Type 26 frigates: new info and some thoughts


My earlier post on the reported troubles with firming up costs for the Type 26 and with getting to contract award have been generating a healthy discussion in the comments section, and that is great. Someone has been reading in my post a sort of hostility from me against the Type 26. I deny this very firmly. My point is another: for what we know about the ship requirements (settled in May 2012 and stable since then) and MOD-endorsed design (which has been frozen in its main lines for quite a long while, now), there is nothing excessively revolutionary that should make this platform unaffordable, considering how much equipment will be carried over from the Type 23 frigates.
It is not my invention, but a fact, that the Royal Navy has deliberately shaped Type 26 as a program which builds on earlier, incremental improvements adopted on the Type 23s and then moved across, without seeking innovation at all costs. A rough figure has been suggested, putting Type 26 in the field of "80% old, and 20% new".
This does not mean that Type 26 won't deliver a step change in capability from the current Type 23s, but rather that it will deliver so using already existing technology, and indeed re-using a fair amount of equipment.
The savings obtained by re-using equipment and by sticking with proven technology and systems are to be employed, in the idea behind the programme, to ensure a decent number of hulls get built, and to ensure that those hulls come with some new and exciting capability thanks to their large size, large aviation spaces and vast "flexible" mission space and, importantly, a large vertical launch silo that will open up routes the Type 23 has simply never been able to pursue.
I very much like the general idea, and my only wish is to see it working as intended.

I'm writing this new article because i've come across some excellent material that provides some great details about the Type 26 design that has been finalized and is being costed ahead of the Main Gate. The document is a letter, dating October 2014, from the Secretary of State for defence to the house of common's defence committee. The SoF replies to a series of direct questions, and provides some excellent information.

First of all, the Flexible Mission Bay. There is no indication of its size and shape, but the SoF finally provides a confirmation that the helicopter hangar is directly connected to the Mission Bay, with a passage large enough to enable the transfer of manned and unmanned aircraft from hangar to mission bay.
Hangar size unsurprisingy at least matches that of the Type 45: the destroyer is slightly larger in beam, but the hangar is not full-width, as it has the RHIB bays on both sides. On Type 26, there are no boat bays, although it is likely that the helicopter bay will be flanked by logistic and aviation stores spaces and by the delivery end of the new mechanized Air Weapons Handling System, designed by Babcock, which is to store, retrieve and deliver the weapons for the embarked helicopter to the Weapons Preparation Area.
Apparently, the AWHS will also handle the Stingray torpedoes for the ship's launch tubes (if they will be fitted, see further down in the article).
The hangar thus can be assumed to match the Type 45's one and it might actually be larger: the SoF says it "comfortably" fits one Merlin or 2 Wildcat. Using the Mission Bay space, more aviation resources could be carried: UAVs, both fixed and rotary wing, but also additional manned helicopters. It would be possible, albeit with limitations, to embark a second Merlin in the Mission Bay, the SoF specifies.
The ability of the mission bay to communicate directly with the hangar (and thus with the flight deck) is an eminently sensible feature to have, and it is good to have the confirmation that it will be there, and with ample chances of exploiting it over the long life of the ships (at least 25 years of design life).

It is also confirmed that the Flight Deck is being sized to allow a Chinook to land and deploy the ramp to enable comfortable embarkation and disembarkation. The compatibility with Chinook, while not strictly necessary, is useful as the heavy transport helicopter could make good use of the ample Embarked Military Force contingent that can sail into a Type 26, and it could also be used to bring aboard capability modules and stores.
Moreover, the Chinook-sized deck should also, and probably mainly, be seen as a way to ensure that simultaneous UAV and manned helicopter operations can happen with suitable space available for necessary deconfliction.
These features add a huge amount of flexibility to the design.


The mission bay itself is a large open space stretching from side to side, with large doors on both sides for deploying boats, unmanned surface and subsurface vehicles, as well as to embark mission modules which can come in containers as big as 20 feet standard TEU.
The mission bay can hold up to four 12 meters boats (and probably a few containers of additional equipment in the middle of the bay, judging from images seen this far) or up to 10 modules / 20 foot containers.
This flexibility will be invaluable in adapting to future missions and in enabling the adoption of future unmanned vehicles which are almost certain to become not just the main MCM system, but also more important in ASW. Having space and infrastructure is, consequently, very desirable for warships which have to last long into the future.
The UK is actively collaborating with France to develop modular payloads for MCM operations, and such developments are happening in other nations across NATO: the UK has taken the lead, according to the letter, for a project that aims to set international standards for the module interfaces, so that foreign systems in future can be embarked and operated where necessary.
One thing which isn't yet detailed is what kind of equipment the ship will have for embarking and disembarking containers and modules: will she depend on external infrastructure, or will the slide-out gantry crane be able to lift not only boats, but also the containers? It will be interesting to see which solutions are adopted. The mission bay will require a strong deck, as reinforced as the flight deck itself. A fully loaded TEU can weight some 24 tons, so a useful payload margin of at least 240 tons is apparently requested. The mission bay estimated size, considering what it can fit, is probably not inferior to a 15 meters long, 20 wide space.


The Type 26 will have a crew of 118, and room for 72 other personnel for the aviation element, for boarding teams, pre-landing forces of the Royal Marines, or for specialists coming to operate the modular mission systems. From the SoF letter, it becomes clear that some real attention has been paid into giving the frigate excellent capability to host the Royal Marines pre-landing party.
In recent times, HMS Montrose, a Type 23 frigate, experimented with a sizeable pre-landing force of over 70 Marines in 2012: must have been a real tight fit on a Type 23, but on the Type 26 there will be space and infrastructure to do much better.

In terms of weapons fit, the letter specifies that the vessels will be fitted at build with a sizeable Flexible Strike Silo numbering 24 cells, for anti-ship, land attack and anti-submarine weapons. The letter specifies that the cells will be american MK41. This is a surprise, since earlier info suggested that since MK41 is somewhat larger than Sylver modules, only two launchers (for 16 cells in total) could be fitted: it appears it is not so, and the higher number of cells has been confirmed in the finalised design.

Confirmed are the 48 Sea Ceptor canisters as well, almost certainly in the two silos configuration seen in CGIs and models so far, so with 24 cells on the bow, ahead of the strike cells, and 24 aft of the funnel mast, amidship.
The Type 26 will have a 127mm gun, too, replacing the old MK8. I'm told that, although it has not yet been officially announced, only the MK45 Mod 4 remains in the frame, with the Oto Melara 127/64 out of the race. Jane's had reported a while ago that the MK45 had been given preferred bidder status, so it seems things are moving in that direction. The new gun will "allow" the Navy to buy into the new long-range guided ammunition being developed for the calibre, which is a NATO standard, unlike the 114 mm of the MK8.
There will also be two 30mm light guns, as expected, and the possibility to fit two Phalanx CIWS.

The list shown in the letter comes without one notable piece, however: it makes no mention of Stingray torpedo tubes, which is very surprising considering that the Type 26 is an ASW platform, and that the launcher systems could reasonably be transferred from the Type 23s.
It is an omission that causes questions to arise: it seems unlikely that there would not be such a fit on this kind of vessel, especially since vertical launch anti-submarine rockets, which are mentioned in the letter, are not in british service, and would have to be somehow procured (read: financed, as that is the issue). It is not a product line where there is much choice: the americans have the ASROC, the italians have the MILAS (which is not vertically lauched, however) and the South Koreans are producing a system of their own. Japan also has its own anti-submarine missile system. None of these is fitted with a british Stingray torpedo, obviously, although this could probably be fixed quite easily.
Not fitting the torpedo tubes would be a puzzling decision, if confirmed. The ship's tubes are admittedly more of a snap self-defence fit than anything else, considering the limited range of the lightweight torpedo fired from them means that the frigate launching them would probably already be under attack by the enemy submarine; but doing away with them entirely, besides while not having a clear path to a vertical launch solution, is questionable.
Might it be just a case of them having been "forgotten" in the letter? Can't be excluded.

The letter also has another nice little bit of a news in itself: the FASGW(L) missile, the Thales Light Multi-mission Missile, has been given the name MARTLET in british service. This hadn't been disclosed to the public before, as far as i'm aware, unlike Sea Venom which was named earlier this year.

(Secretary of State for Defence - Type 26 letter to the defence committee)




A displacement of 8000 tons? 

Type 26 is going to be a large and "dense" warship. The 6000 tons displacement quoted by BAE is pretty much certainly not the weight of a fully loaded Type 26, and indeed some recent news reports have suggested that the ship might now be an "8000 tons full load displacement vessel". I'm however not sure i can believe the 8000 tons value at this point, because it sounds excessive in relation to the specifications and the size of the vessel, but it will be an heavy ship, that's for sure. The SoF letter does not provide any helpful indication about this subject.

Type 26 is 148,5 meters long and around 20 meters in beam. Not too far from the 144,6 and 19,7 meters of the italian variant of the FREMM frigates (the french ones are slightly shorter, as the italian ships are being lenghtened post-build by some 3,5 meters adding an additional section in the stern) which have a declared displacement of 6700 tons, sometimes indicated in more than 7000. The italian navy has released some different, contradictory figures for the displacement, which consequently isn't identifiable with certainty. Even the reason for the lenghtening isn't yet fully clear: officially, the expansion was mainly due to the need to improve all-weather operations with the AW-101 Merlin helicopter and was exploited to provide additional accommodation space, 100 tons of additional fuel (bringing endurance to 6700 nautical miles against 6000 earlier) and a second RAS station. The weight increase coming from the lengtening was indicated in 250 tons.
Unofficially, there have been strong suggestions that the lenghtening has been inspired by the wish to correct weight distribution, as the italian FREMM have been given the same huge main mast of an Horizon destroyer, carrying the heavy, powerful EMPAR radar system, and this has, again reportedly, made the ship remarkably bow-heavy, with consequences on handling, particularly in rough seas.

In many ways, the italian FREMM is a good comparison to Type 26: the italian navy is taking delivery of two variants, the General Purpose and ASW. The first replaces the towed sonar of the second with a stern ramp for the deployment of a 11-meters RHIB. The other main differences are that the GP is armed with a 127 mm gun and a 76 mm gun-CIWS, while the ASW has two 76 mm guns. The GP is, for now at least, not fitted with the SLAT anti-torpedo decoy system, which is instead standard on the ASW.
Both ships carry two helicopters in two hangars: one, slightly larger than the other, can house an AW-101 Merlin, while the other is sized for the NH-90 helicopter. The frigates can employ one AW-101 and one NH-90, or two NH-90.
In fairness, i've heard comments suggesting that the AW-101 hangar is quite tight, and considered more adequate to carry a NH-90 and offer spaces for its maintenance rather than allow the actual enduring embarkation of an AW-101 Flight. The smaller hangar bay has been described as just large enough to house the NH-90, without work spaces, so it does seem more practicable to go with two NH-90s, which is by the way more likely as Italy is procuring 40 to 46 NH-90 NFH, while the AW-101s are much fewer (10 ASW, 8 amphibious assault / transport and 4 AEW) and generally meant for use on the Cavour aircraft carrier.  
Both ships employ one 11-meters RHIB and one 7-meters one, with the GP adding a second 11-meters in the stern, as already said.

It would be interesting to have an accurate displacement value, as it could provide a useful ballpark idea for what the Type 26's own displacement might be.

The italian FREMM has accommodation for at least 200 following the modifications (180 on the french FREMM), but also has a core crew considerably larger than the french variant (108 including 14 men of the helicopter flight): the GP was meant to have a crew of 131, and the ASW of 133. Use of the platform at sea has since inspired an expansion of 34 men, as well as some 23 for the aviation department.
The increase in crew size has had some impact on the vessel: currently, the space originally preserved to fit two 8-cell Sylver A70 launcher modules for strike missiles has been sacrificed to provide additional accommodation spaces.
The standard of accommodation, especially in the original rooms, is very high. The room with more bunks has only 4 beds. That's a lot of volume used in what does not appear to be a very efficient way.  

The Type 26 is aiming for a core crew of 118, with accommodation for another 72 personnel. On the Type 45, junior rates sleep 6 per room. On the Queen Elizabeth class, the 6 bunks rooms are larger, but come with two folding beds which can be used to embark 2 more personnel.
On the Type 26, which will need some pretty well optimised use of space for fitting accommodation for 190 plus a large flexible mission bay and a substantial number of VLS, the arrangement of bunks has not yet been detailed. However, back at Euronaval 2012 some reporters talked about 9-bed rooms, a bit of a sacrifice in terms of crew spaces to make everything fit.

Sensor-wise, the italian FREMM is fitted with the EMPAR, as said earlier, a system considerably larger than ARTISAN 3D: the antennas of the two systems weight 2,45 tons against 0,7 tons.

In armaments, the italian FREMM carriers two 8-cell Sylver A50 modules, with the SAAM - Extended Self Defense control system, which enables limited area defence employing not just Aster 15 but Aster 30 as wll. The limitation in area defence performance comes, effectively, from the fact that the FREMM does not support the EMPAR with a long-range radar as happens instead on the Horizon destroyers.  
Type 26 will be able to employ up to 48 CAMM / Sea Ceptor missiles, distributed in two silos. Weight-wise, despite the big difference in numbers, it is the SAAM-ESD that weights the most, since each Aster 15 in its canister weights a full 550 kg, with Aster 30 reaching the 700 kg, while each CAMM canister is in the region of the 100 kg, and being a cold-launch weapon it does not need a VLS as bulky and complex as Sylver (over 8 tons per module, but exact weight not available).
The FREMM armament is completed, in the GP case, by a 127/64 gun (34 tons with turret ammunition drums filled with 56 shells) plus 305 shells in an automated handling two-storey ammunition depot; two 25 mm guns, two triple MU-90 torpedo tubes, eight TESEO anti-ship missiles (770 kg each in their canister) and a 76mm gun on top of the hangar, weighting 7,9 tons without ammunition.

The Type 26 however will have, as of October 2014 information, 24 MK41 strike lenght cells available in addition to Sea Ceptor. Each module, bare of weapons, weights some 14,5 tons. If each cell was filled with a MK14 Mod 2 canister containing a Tomahawk missile (the heaviest, at 2,777 kg each), the weight would rise rapidly! The maximum weight of the Flexible Strike Silo, launchers plus Tomahawk canisters, could be in the region of an impressive 110,15 tons.
However, to this day there is no real indication yet of what the Royal Navy wants to fit. Tomahawk appears to be likely, but the Royal Navy also needs to replace Harpoon, and the only MK41 candidate which could be readily available by then would be the american LRASM solution. The anti-submarine "rocket", if it will be actually pursued at some point, would be another novelty.

The italian FREMM carries enough fuel for 6700 nautical miles, and enough stores for 45 days, officially. The Type 26 reportedly aims for no less than 7000 nautical miles and 60 days, so there might easily be dozens of tons of difference in the amount of fuel carried, and a significant difference in the volume and weight of stores, as well, but providing exact figures is not possible at this point.
The propulsion systems have in common the presence of a gas turbine and four diesels, but that's about it. The italian FREMM uses a 32 MW LM2500+ G4 gas turbine and 4 Isotta Fraschini VL1716 diesels and 2 Jeumont Electric motors, while the Type 26 will have a 36 MW Rolls Royce MT30 and 4 MTU V20 diesels generating 12 MW. However, the FREMM is a CODELAG ship which can run the gas turbine and the diesels at once to sustain high speed in rough sea or obtain greater max speed, thanks to a RENK 170-175 gearbox set weighting some 120 tons; while the Type 26 will be CODELOG, which means the diesels will be used to generate electric power for silent cruise speed, but will be detached when max speed is requested, leaving the sole MT30 to directly drive the two shafts.
The electric motors of the Type 26 are to be supplied by General Electric, and the gearbox by David Brown.

Overall, it is quite natural to expected a loaded Type 26 to exceed 7000 tons and the weight of the slightly smaller and less armed FREMM, but 8000 tons would seem to be an exaggeration.



Costs  

It is a good thing that the Type 26 does seek to reuse much of the expensive equipment fit (main radar, Future Local Area Air Defence System / Sea Ceptor, light guns, navigation radars and other equipment) and build on existing technology (including the shared infrastructure common combat system, which is being rolled out across the Royal Navy's surface fleet in the coming years, having already been installed on HMS Ocean, ordered for the Type 23s and mandated for the new build OPVs), because otherwise there would be no chance to meet the ambitious cost targets set for the programme.
The hull is going to be big and capable, and very dense, with such big spaces being requested for the Strike VLS, mission bay, fuel and stores. The Strike VLS fit is not new (it builds on something that is operational on hundreds of ships around the globe) in general terms but is a new entry in the Royal Navy, so will need to be acquired anew.

Ultimately, we do not know which is the current target pricetag for the Type 26. The newspapers have recently made headlines about Type 26 being a 4 billion project, but this isn't too helpful because government has notoriously indicated that there is likely to be a first contract for 8 ships, to be followed (hopefully) by 5 more later. If 4 billion applied to the first 8 hulls only, the cost per ship would 500 million pounds, rather non ambitious at all. On the other hand, 4 billion for 13 ships would likely be too little, at little more than 307 million per hull. Result maybe not beyond the realm of the possible in general terms, but looking too ambitious for british shipbuilding, which isn't really famous for being cheap.

Maybe the danes could get it done: they have very successfully built the IVER HUITFELDT class frigates, three capable air area defence warships which have cost an amazingly low 313 million USD each.
These impressive vessels, however, build their hulls on the experience of the commercial operator Maersk, a factor not to be underestimated. The design has also benefitted from previous work done to design the Absalom class, another success story.

The IVER class use a fully-diesel propulsion with 4 large MTU sets which can push the ship for 9300 nautical miles at 18 knots, but that can also thrust her to over 29 knots speed with a 120 seconds acceleration time. The base crew of 116 isn't too far from Type 26's target, nor is total accommodation available, set at 165+ men.
The IVER is a 6649 tons displacement vessel, about as large in beam as Type 26, but around 10 meters shorter.
The ships are fitted with an advanced combat system and with the excellent APAR multi-function radar used also on the german SACHSEN ships, supported by the SMART L, the long range radar which equips the Horizon and Type 45 destroyers (in the S-1850M variant). They have a 32-cells MK41 Strike Lenght silo amidship, supplemented by 24 additional cells for ESSM missiles and by space for more ESSM or for up to 16 Harpoon. They are fitted with two 76 mm guns, and a Millenium CIWS, but could soon enough swap one 76 for a MK45 MOD 4 gun. The other 76 could stay or be replaced by another Millenium.



Amazingly cheap, these ships deliver formidable value for money. The budget for all three was 940 million USD, supplemented by 209 million in re-used equipment (ESSM cell modules, Harpoon and 76 mm guns, mainly). The budget did not include the purchase of the SM-2 missiles for air area defence, so for now the MK41 is empty and only ESSM is available, and the 127 mm gun is planned but not yet purchased.
Deep in the hull, they have space reserved for a towed sonar, and further space for other equipment with a footprint equivalent to four 20 feet containers. 







It will be a big challenge for the british shipbuilding industry to keep Type 26 costs down. There is no revolutionary system being requested, but on the other hand there is admittedly quite a lot of capability being designed into a dense hull.
The amount of re-use of existing equipment migrating from the Type 23 could be a real lifesaver for the programme: the abundant carry over should represent a big "saving" of sort (money will have of course have been spent for all items, but early and separately), especially since it covers most of the big-money items of the combat equipment.

Saying how much it will cost to fit the new MK45 main gun and the MK41 silo is not easy, but thanks to an immensely useful USN document detailing the cost of new build DDG-51 destroyers by major subsystems, i've put together a ballpark estimate. Take it with prudence and salt, of course: this is a very rough method for estimating costs, but i think it is interesting enough to be included as a basis for discussion and reflection.



To provide a rough cost indication, i've scouted US Navy documents which helpfully provide a major breakdown of the cost of a DDG-51 by major subsystems and related components and activities, looking at the years 2013, 2014 and 2015. There are, as always happens in these things, some pretty large variations in price from a year to the next, but it is at least possible to get an idea. The yearly data suggests that ordering many in the same years significantly lowers the costs with economies of scale. (USN document)




The MK41 fit on a DDG-51 is a 12 launch modules affair, with a cost in the region of the 48 million dollars. 12 modules, however, are the fit of 4 Type 26s, according to the info we now have. So it might take around around 160 million USD to put 24 MK41 cells on all Type 26s. Rough estimate, of course, i want to say that again. The number of modules is lower per hull, but there are more ship sets. However, there should not be a big difference per se in terms of ship sets installation. Dropping 36 modules in three hulls or 39 in 13 hulls shouldn't be excessively different, but for the fact that they would be separate operations happening on different years. This might raise the cost, but overall i would like to think that things would even out in a reasonable way.

If it is decided that the Type 26s have to be able to successfully employ Tomahawk, they need the Tactical Tomahawk Weapon Control System fit too, and that could require up to some 16 million USD per ship (cost for a single ship set in 2014, the unitary cost drops as low as 11 million with 3 sets in 2013 and 13 million with 2 sets in 2015). 16 million for all 13 ships would add up to 208 million for the class. Again, rough estimate. All costs inclusive of technical support, engineering, initial spares etcetera. I don't know if LRASM has a comparable, separate mission planning system. Probably not, but there would be of course integration costs of its own with it having its own backend in a shape or another.

The rest of course depends on the missile, and how many All Up Rounds are purchased. The last Tomahawk contract, which included 20 submarine torpedo tube TLAM for the UK, was a firm fixed price order for 231 rounds (147 Vertical Launch rounds for US surface warships, 64 encapsuled rounds for US navy submarines with VL cells and 20 torpedo tube launch TLAM rounds for the UK) for 251,13 million dollars.


In theory, and i'll say it again in theory and in rough estimates, 24 MK41 cells + Tomahawk mission system + 231 missiles (using the 231 figure and its cost, even though the torpedo tube missile is more expensive than the VL) = 619.13 million dollars, or around 396 million pounds, at today's rates. And that's with a 231 TLAM order thrown in for good measure, that we all know isn't going to happen. Probably there would be a finite, much smaller number of missile loads purchased, and the deploying ships would stop by the Upper Harbour Ammunitioning Facility prior to deployment to take the rounds on board, since pretty much never are we going to see all 13 vessels on operations at once anyway.

All this, just to have a ballpark idea based on something. Better than speaking purely on wild speculation.
If you follow the link to the US Navy document, you'll see that it quotes Unitary Item Costs which are all much lower than the amounts i used. I did that deliberately, by looking at the total expense per ship related to the various items so to include, albeit of course in a rough way, the spares, engineering and services costs which are very much inevitable. Using the unitary cost alone would not be realistic, as the amounts resulting would be much lower than the real ones. In this other way, the cost figures should be much closer to the truth. 
This is mainly to indicate that it won't be the fitting of MK41 launchers that will break the programme's budget on its own: they fit 32 MK41 cells on the cheapest high end combat ships out there, as we saw.

As for the MK45 Mod 4, it is also of some interest to see its cost is in the region of some 25 million apiece, apparently. Again, the cost for a british purchase might be different, and it is indeed likely to be somewhat higher since for the UK it will be a totally new system, while it is business as usual for the US Navy. 



In this long piece, i've wanted to share the quality info i've found about what the design of Type 26 offers, and i've also tried to explain why i talked the way i did about the reports of cost issues and the delay in clearing Main Gate. The requirements, taken as a whole, are ambitious in several ways, and i won't deny that. But they have maintained steady over time, and they are being mitigated by a responsible approach to the programme. I hope that now the whole package can be made to work, and work well. Because one thing is certain: this programme is of vital importance to both the Navy and the british shipbuilding industry. It is in the interests of both that it goes as planned. 
If it did, it really might be a renaissance for british yards, because this ship, while not revolutionary in its subsystems, is very much (r)evolutionary in terms of what it delivers as a whole. A good product at a reasonable price: what is needed for the Navy to survive, and for export orders to return to british shipyards.

News roundup: from airshows and elsewhere




HMS Queen Elizabeth undocked

After being named, the aircraft carrier has now been carefully eased out of No 1 Dock in Rosyth, to be berthed in the shipyard’s basin, where the ship will be completed. The dock will not stay empty for long: the LB03 superblock for HMS Prince of Wales has already been loaded onto a barge for the travel to Rosyth, planned for next week. LB01 (the bow) is already in Rosyth, ready to be craned down into the dock. CB02 has been loaded on another barge itself.
Progress on Prince of Wales will be rapid: it is expected that the assembly phase of the second carrier will take 12 months less thanks to a more efficient process and to the experience made with the first-in-class.  

Moving the carrier out of the dock required a flottilla of tugs. One of them had to be lifted whole via Goliath crane, to be then lowered in the dock, ahead of QE's bow!






F-35 visit to the UK is cancelled even as flight resumes

The June 23 fire on the USAF F-35A AF-27 in Eglin has ultimately, as was to be feared, proven to be a big enough issue to prevent the planned international debut of the F-35. The investigation that followed the incident has located the problem in the F-135 engine, specifically identifying excessive friction between the third-stage integrally bladed rotor and an abradable strip lining the engine casing as the cause for the engine failure, which cut a fuel line and sparked the fire. A general inspection, fleet-wide, has been made on all the engines in the fleet, and it seems that the problem is an isolated anomaly. However, the F-35 fleet has for now only been allowed to flight within strict restrictions which include mandatory engine inspections. The investigation, in fact, is not yet complete and it has so far not been possible to isolate the root cause, a fundamental passage to clear in order to safely determine if other engines are at risk or not.

The restrictions put an end to the hope of seeing the F-35 cross the Atlantic to debut abroad for the first time. It must be noted however that F-35Bs of the USMC have actually flown long-endurance flights across the USA twice after the June 23 fire, as three aircraft were flown from Yuma to Patuxent River on July 27, and they yesterday flew back to Yuma, trailed by tankers.

Other F-35 news include the signing of the contract between AIM Norway and Pratt & Whitney for the standing up of an F-135 engine Maintenance, Repair and Overhaul (MRO) centre in Norway. This is the first such centre selected, and is of special relevance to the UK as well, since cooperation agreements between Britain and Norway have all included the plan to eventually have british F-135 engines maintained by AIM Norway.
Two more engine MRO centres are expected to stand up in Europe on the back of other Pratt & Whitney agreements: one MRO line is expected to open in the Netherlands, at the Fokker Woensdrecht centre. This facility, yet to be contractualized, is a key component of wider multinational F-35 agreements, as the Netherlands expect to maintain Italian F-135 engines in exchange for the assembly of their F-35 jets in Italy’s FACO in Cameri.
Finally, Pratt & Whitney has signed a LOI on May 22, 2014, to help Turkey stand up not just a MRO centre but a true engine-FACO which will also be able to assemble engines in support of the F-35 program. However, while Norway and the Netherlands already have a clear path to achieve at least one major client outside of their own airforces, Turkey has yet to find its place in the enterprise.

Meanwhile, the first third generation Helmed Mounted Display systems for the F-35 program have been delivered for testing. They have been trialed in flight to the satisfaction of test pilots, but so far only on substitutive flying-lab aircrafts. Trials will now be made using F-35A AF-3, a test aircraft fitted with Block 3I software and TR2 processors (both appearing starting with LRIP 6 aircraft). It is expected that the third generation helmet will be delivered as part of the LRIP 7.

Later this year, it is expected that negotiations will be concluded and a contract signed for LRIP 8 production, expected to include 4 F-35B for the United Kingdom.

The United Kingdom is preparing to move personnel and aircraft out of Eglin towards the next destinations: 13 engineers and one pilot will follow the USMC training squadron 501 as it moves from Eglin to its intended permanent base in Beaufort. The USMC move is underway, with the first aircraft having transferred yesterday, following the early move of part of the personnel. The first training courses in Beaufort are expected to begin in the fall (October most likely), with the full transfer completed in 2015. Beaufort is where 617 Sqn RAF will stand up, train and grow before moving to Marham in the UK in the summer (july/august) 2018. By December 2018, land IOC is expected to be declared. The same year, HMS Queen Elizabeth is expected to sail across the Atlantic to have her first aviation trials embarking F-35Bs in the US East Coast area.  

The rest of the current british F-35B personnel (3 pilots and 16 to 20 engineers) will move to Edwards AFB, where they will, later this year, stand up 17(R) Sqn as the OEU unit.

Lockheed Martin, Northrop Grumman and BAE Systems are due to invest 140 million dollars between 2014 and 2016 to fund affordability and cost reduction approaches in order to reduce the Unit Recurring Fly-away Cost to “4th Generation levels”.
Another measure being studied to achieve affordability is the project for a “block buy” which would see international partners committing firmly to substantial number of aircraft in the next few years, in exchange for a “discount price”. This is meant to encourage partners to help the US ramp up yearly production numbers ahead of the passage to full rate production and Multi-Year Procurement, so to achieve the cost reduction that everyone is hoping for.

On the testing front, there are good news. Structure durability testing has concluded in Brough, UK, on the horizontal tail surfaces for all three F-35 variants. They have survived the 24.000 hours of simulated flying, equivalent to three design lives (the F-35 has a design life of 8000 hours, against the 6000 of aircraft such as Typhoon).
Next year, the same kind of testing should be completed on the vertical surfaces as well. Brough is also doing the durability testing on the F-35A fuselage, and by next year it will clear the second of the three lives in testing.  



The F-35B remains on track to achieve the intended USMC IOC. The final version of the Block 2B software is flying, and testing is progressing, including on complex features such as four-aircraft situational awareness sharing via MADL secure link.
In October and out to early November, 2 F-35C will embark on USS Nimitz for the first sea trials of the type.
Block 3I software testing in flight is also on the way. This is important because Block 3I is needed for acceptance of the LRIP 6 jets.
Block 3I is the Block 2B software hosted on new, more powerful TR-2 processors introduced on the aircraft from LRIP 6 onwards. TR-2 processors are needed to eventually receive the complete Block 3F software, and will be retrofitted to early production aircraft going ahead.  


HMS Illustrious close to retirement

HMS Illustrious will soon decommission. On July 22 she will make her last entry into Portsmouth. Just days ago speculation had made the rounds about her Out of Service Date being pushed back by the delay of 3 months suffered by HMS Ocean’s big refit. It was suggested that Illustrious might have to deploy once more, as part of the Response Force Task Group for Ex Cougar 14, due to HMS Ocean not being ready.
It won’t be the case. HMS Ocean is now busy in post-refit sea trials, and is starting aviation trials: it looks like the trials will be speeded up to allow her to take her place at the centre of the task group, as originally planned.

CBRN reactivation goes ahead

A further step has been moved to restore CBRN wide area recce capability, putting out a tender notice for the regeneration of the Fuchs armored vehicles. The tender covers 9 vehicles, down from 11, but is a key advancement in the story. The regeneration will include spares, logistic support and support for future updates. 3 years of support, plus two 1-year extension options are envisaged. The cost range is between 7 and 11 million pounds.


Sentinel, Shadow and Reaper to stay

Despite providing little actual detail along with the announcement, David Cameron’s much publicized address at Farnborough confirmed the unlocking of funding meant to keep Sentinel and Shadow serving at least out to 2018, reversing the decisions outlined in the 2010 SDSR.
Reaper was not mentioned in the announcement, but it is understood that it will be brought into core and funded for at least five years. A formal confirmation of the plan to retain the RPASs has not yet come as the Royal Air Force is still firming up a decision on where to base the aircraft when it comes back from Afghanistan. It must also be noted that, as of now, personnel from 39 RAF Sqn remains based in Creech AFB, USA, with one Ground Control Station, to maintain the direct ties with the USAF’s own RPAS force. A british pilot is embedded in the 556th Test and Evaluation Squadron, which stood up in march 2008 as the first UAV operational test squadron in the USAF.
39 Sqn had been originally planned to move into Waddington, alongside XIII Sqn which stood up there in 2012 when the other two british Ground Control Stations were transported from Creech to the british base. The two GCS have been housed inside one of Waddington’s hangars to ensure maximum security.
Meanwhile, the last five british Reapers have begun to operate in Afghanistan, after several months of delay due to the challenge of validating the changes and upgrades present in these more recent RPASs. 


The Sentinel R1 will not just be retained, but it will actually receive significant upgrades over which the RAF and Raytheon are already working. It is likely that one of the five aircraft will be devoted to a program of assessment of the upgrade program in the next months: the development paths being considered involve introducing a maritime search mode for the radar; adding long-range EO/IR optics, probably derived from the sensor employed by the DB-110 RAPTOR reconnaissance pod, primarily for high definition, visual validation of radar tracks; and a SIGINT sensor fit.
A maritime radar mode won’t be an MPA replacement, but it will help to fill the gap somewhat, by restoring a wide area surface surveillance capability.


Tornado GR4’s last upgrades

Despite being planned to leave service in March 2019, the Tornado GR4 is still receiving upgrades. 59 aircraft will receive the full package of upgrades (once planned for 96 aircraft) by the end of March 2016, in order to stay relevant until their very last day of service. The remaining Tornado aircraft will be used as a source for spare parts for the forward fleet.

The upgrades include the Tactical Integrated Exchange Capability (TIEC) Data Link 16 and Improved Data Modem capability, which fills a gap which was badly felt in 2011 over Libya. The TIEC program had been in the works from well before operation Ellamy, however (dating back easily to 2004), and had been working to introduce Data Link 16 on the Harrier GR9 first.
The upgrade program includes secure communications fit by Cassidian, and full integration of the Paveway IV guided bomb.

Tornado has received substantial improvements in recent times. For operations in Afghanistan, it was fitted under UOR with the Advanced IR Counter Measures (AIRCM) pod (a customised version of Terma's Modular Countermeasures Pod/MCP) and a CAGNET multi-band transceiver (based on a Rohde & Schwarz MR6000L software radio) which embodies the Have Quick II waveform used for air-ground communications with JTACs.
CAGNET was a stop-gap measure on the way to SCOT (Secure Communications On Tornado), a program started in 2005 and rolled out from 2010 that uses the same transceiver but opens up additional waveforms including SATURN for satcoms.

Tornado also received an Helmet Mounted Display fit for target cueing purpose. At least twelve HMD sets have been procured, and the fleet has been progressively fitted for but not with, so that deploying aircraft can bring the system to bear.

A Honeywell TCAS II anti-collision system has been fitted to two aircraft for development and demonstration, and trialed on a third. It will be rolled onto the whole fleet later this year, in a much delayed answer to the risk of in-flight collisions: 3 RAF crewmen from Lossiemouth died in a collision between two Tornado in 2012, and further collisions had happened in the past, including a tragic impact with a Cessna which caused 4 deaths in 1999.  

The AIRCM gave the Tornado GR4 increased protection against IR missiles, and a new contract is due to completely renew the Skyshield 2 pod, carried on the other wing, to massively enhance protection against enemy radars.
Selex ES will take the existing Skyshield 2 pods and rework their internal structure completely, replacing the entire receiver chain, introducing a digital control unit and a digital techniques generator as well as updating to the TWT transmitters. Two Towed Radar Decoys (TRDs) identical to those currently in service with the Eurofighter Typhoon will be incorporated into the rear of the pod. Flight trials are expected by the end of the year, with IOC in late 2015. 

Skyshield 2 pods have not quite kept up with enemy radar developments. In Afghanistan, the lack of radar-guided threats has lead to Tornado often flying with a BOZ simulacre (with the only purpose of keeping the aircraft balanced) instead of a Skyshield pod (unlike the Tornado in this picture, which has it under the left wing)


This Tornado carrying RAPTOR is equipped with an AIRCM (to the right, in the picture) and a simulacre (on the left). No Skyshield 2
  
The TERMA AIRCM was introduced as UOR to protect Tornado against possible IR-guided threats. The AIRCM combines missile warning sensors and flare dispensers, slaved to an Electronic Warfare
Management System, AN/ALQ-213(V) which automatically reacts to a threat by deploying the adequate countermeasure while giving the pilot video and audio warnings as suitable.

Selex ES has received a final  support contract for Tornado, which will carry it towards OSD.




Typhoon AESA and Storm Shadow

The E-Scan Radar Development Programme for Typhoon is currently still within the Assessment Phase, prior to its main investment decision. In fact, despite the fanfare at Farnborough, a go-ahead contract has yet to be signed. United Kingdom and Italy appear to be ready to sign, but Germany is known to still have to secure parliamentary approval, and until the contract is signed, we are still stuck at the hopes level, like it has already happened many times in the past years. The Typhoon AESA story has been a long and so far disappointing tale.

The contract, once it will be signed, is expected to be worth a billion pounds, spread on the partner nations, but there are no confirmations. The signing of the deal is expected before year’s end.

At Farnborough, as announced by David Cameron, a british-only £72 million Extended Assessment Phase contract has been awarded to BAE Systems, to de-risk UK specific requirements as part of the pre-main investment decision work. It has long been known that the RAF has set ambitious and extensive requirements for the Typhoon’s AESA, to include electronic war functions. This is not the first work that is authorized into developing those additional features, with the most well known earlier project known as Bright Adder.
The RAF hopes to install the AESA radar on its Tranche 3 aircraft, and have the system operational in the early 2020s.

A final contract has instead been signed for the integration of Storm Shadow on Typhoon. Earlier, the first study contract for integration of Brimstone 2 had been announced. The RAF wants to have both weapons integrated on Tranche 2 and 3 Typhoons by 2018, in order to be ready when Tornado GR4 is withdrawn in March 2019.

 
Ongoing work is evaluating how to add a collision avoidance system to RAF Typhoons, as well.

The RAF is also probably in talks with BAE regarding their Striker II Helmet system. The Typhoon currently employs the Striker I, but BAE has already developed a follow-on thanks to the work made into the F-35 program to provide an alternative HMD.
Striker II is a fully digitally integrated helmet display which removes the need for the pilot to wear Night Vision goggles at night as it comes with an integrated ISIE-11 sensor camera. The night vision is then projected binocularly onto the visor.

Striker II will be flown on a Typhoon already later this year. BAE won’t disclose who it is talking to, but it reasonable to assume that the RAF will be interested.

The RAF is also considering its options regarding recce capabilities beyond Tornado GR4 and RAPTOR pod. Rafael is said to be offering the new TopLite MHD (Multi-High Definition) for Typhoon integration: the pod offers visual, near infrared, medium-wave infrared, short-wave infrared and laser units integrated in the same stabilized package. It can also cover the targeting role currently performed by the Litening III, also by Rafael.  



Brimstone

On the complex weapons front, MBDA has announced that Brimstone 2 series production has now started at Henlow, and the missile will be operational on Tornado GR4 next year. Typhoon will hopefully follow by 2018. Brimstone 2 is the solution for the SPEAR Capability 2 Block 1 program. Future evolutions of the missile are expected, which could see it being adopted on British Army Apache helicopters from around 2021 as a replacement for the Hellfire as it goes out of service. Successful firing trials on a Reaper have been concluded, and integration could follow pretty soon.

Paveway IV

Raytheon provided an update regarding the development of new capabilities for Paveway IV under the SPEAR Capability 1 program.
SPEAR Capability 1 is, as always, further broken down in blocks. Block 1 is about the development of a low-collateral damage warhead option. Tests on the ground have already been carried out.
Block 2 is about developing a capable bunker-buster warhead. The challenge is achieving good penetration and lethality while maintaining the external shape and the current 500 lbs mass of the warhead, to avoid costly trials and integration procedures. The bunker-buster warhead has an external shroud which makes it look like a base warhead, but the shroud is shredded on impact as the special, hardened core penetrates deep into the target. The objective is developing a suitable replacement for the much larger 2000 lbs Paveway III BLU-109, which is not expected to be integrated on Typhoon and F-35B and thus looks set to end its career together with Tornado.

On its own, outside of SPEAR, Raytheon is developing a new digital seeker with high off-boresight field of view and proportional navigation to enhance the capability to hit moving targets running at up to 70 mph.
Raytheon is also working to offer enhanced, active anti-jamming GPS guidance. All capabilities should be available by 2018.
Improvements have been rolled out onto the Paveway IV already several times: the over 4000 bombs produced for the UK MOD have in fact actually been delivered in at least three marks (MK 0, MK 1 and MK 2).

In the next few years, it can be anticipated that Paveway IV, with its various new warhead options, will replace all other, earlier Paveway iterations in the british arsenal, with obvious logistic advantages.

SPEAR 3

Development of SPEAR 3 continues, and at Farnborough a mock-up gives us a first vision of the Common Weapon Launcher option that MBDA has been asked to come up with to ease SPEAR 3 integration on Typhoon. The Common Weapon Launcher has the same general shape and mass of the current triple rail Brimstone launcher, so that the two different weapons can capitalize on the same flight trials, with the savings that this enables. It is worth remembering that SPEAR 3 actually sees light with a SDB-like quadruple rack especially meant to maximize internal carry capability on the F-35.

SPEAR 3 has many points of contact with the American Small Diameter Bomb II by Raytheon, and indeed Angus Batey writes from Farnborough about the drive of Raytheon to try and sway the MOD away from the MBDA product.
Despite all the points of contact, however, it must be noted that SPEAR 3 is a powered weapon, while SDB II only glides. SPEAR 3 has two small side intakes for its Hamilton Sundstrand TJ-150 turbojet, and the engine opens up a whole range of unique capabilities for a weapon so small. This 80 kg mini-cruise missile can be launched even when not facing the target (differently from SDB) and with more freedom regardless of launch height and weather conditions that affect gliding. The weapon is to be able to engage fixed and mobile targets alike, with a data link enabling post-launch control and retargeting. The propulsion is also fundamental in order to achieve the range of at least 100 km that the MOD wants. SDB is a 45 nautical miles glide weapon, while MOD and MBDA believe they can achieve north of 62 nautical miles for SPEAR. 

SPEAR 3 comes with a quadruple rack, but for ease of integration, the triple launcher could be used on Typhoon.

MBDA is also offering a vertical launch SPEAR 3 development for future use ashore and on warships. Four SPEAR 3 rounds could be fitted inside a single MK41 cell, for example on Type 26 frigates.

FASGW

After many delays, FASGW is finally on the move, with all contracts signed. 48 million pounds are going to Thales to complete development and validation of LMM and of the five-round launcher, the FASGW(H) contract has been signed time ago with France, and at Farnborough a 90 million deal has been signed with AgustaWestland to integrate both weapons on Wildcat. 

Sea Venom integration contract is signed
 
The FASGW(H) has also a name, finally: according to Jane’s, the MOD has chosen the name Sea Venom. 

Thales has also showcased for the first time one LMM derivative that was known to be in development: the Free Fall mini munition, primarily meant to arm UAVs. The FFLMM is a gliding mini-bomb obtained by removing the LMM rocket motor and adding redesigned wings. The weapon is 70 cm long, 7.6 cm in diameter and weights just 6 kg while retaining the LMM's dual-effect shaped charge and pre-fragmented blast warhead

Thales has added INS and GPS navigation as well as a semi-active laser guidance that replaces the beam-riding system currently used on the LMM. An airburst fuze is a possible development for the near future. The weapon will glide 4 kilometers if dropped from 10.000 feet, and 3 munitions can be carried on an Hellfire rail. 



The british MOD so far has not committed to this variant, but has been involved in its development. Development launches were made from a Lynx AH7, for example.



FCAS and Storm Shadow MLU

Two Memorandum of Understanding documents have been signed with France at the Farnborough airshow: one sets out the course of the next phase of joint studies for the Future Combat Air System (FCAS), the UCAV to be jointly developed for the 2030s.
The other MOU covers the next phase of joint activities aimed at the incoming Mid Life Upgrade for the Storm Shadow missile.


More Merlin HM2 might still be within reach

After the successful exercise Deep Blue, which saw Illustrious deploying in the Atlantic with 9 Merlin HM2 and two Type 23 frigate escorts to stage a full-size ASW war against four between british and French nuclear submarines and dutch diesel-electrics, the RN has achieved IOC with the first 15 Merlin helicopters upgraded to HM2 status.

Flight trials of the two systems in the race for CROWSNEST will soon be ongoing, beginning with the Lockheed Martin VIGILANCE podded solution “in the coming weeks”. The THALES solution based on the current, well known Searchwater “bag” will follow.

The key development emerged at Farnborough is that the Royal Navy has obtained a re-evaluation of the case for upgrading some more helicopters. The original HM2 plan was for 30 helicopters and 8 options, but at one point the option was dropped and it seemed to become more or less official that the 8 HM1 remaining would be shelved.
The Royal Navy is now trying to flesh out a plan for the upgrade of some more helicopters, up to 8 of them, in recognition of how high in demand the Merlin is and is going to be. The current assumption is that the 30 Merlin HM2 will have to deliver a forward fleet of 25, 14 of which would be committed to the aircraft carrier when it deploys at sea. The 14 helicopters would cover the requirement for an ASW force of 9 (to ensure 24 hours coverage) and an AEW group of 4 to 5 helicopter swith CROWSNEST kit.
Add to this training needs, the unexpected and the need for frigate small ship flights, and it becomes evident how hard worked the fleet would be.
Obtaining more HM2s would be a massive boost.


UAVs at sea

The Scan Eagle contract for the Royal Navy has been extended out to June 30, 2017. The earlier contract would have ended in April 2015.
Meanwhile, AgustaWestland is continuing to develop the optionally manned SW-4 SOLO helicopter. It has showcased it in unmanned flight to the Italian ministry of defence, the company announced, and later this year or early in 2015 the system will be used for the Royal Navy’s RWUAS demonstration campaign which is expected to include operations at sea on a Type 23 frigate.


RAF A400M deliveries to be accelerated by 3 years  

The A400M has received around 80 tons of fuel in air to air refueling trials which used the Voyager tanker that the RAF is providing for the Atlas program in Getafe. Parachute launch trials have also been cleared, and will continue with expansion of airdrop capability to include low-level, high-weight load extractions.

Program-wise, the RAF now expects to receive its full fleet of 22 aircraft by March 2018. Until last year, the 22nd unit would have not been delivered before 2021.
The deliveries have been reprogrammed thanks to a swap of production slots with France. This year, starting with MSN 15 in September, the RAF will receive four aircraft. Six more will follow by the end of next year, with the balance spread over 2016, 2017 and early 2018.
