Strategy is a long term vision


There is not too terribly much that can be said on sir Parker’s review of the UK shipbuilding situation, at the moment. His is merely a list of suggestions, an independent report which might or might not generate policy changes. To know whether his recommendations have changed anything, we’ll have to wait for the actual Shipbuilding Strategy which the government has promised to publish sometime in “spring 2017”.
That document is the one we want to read, and the one from which answers should come. We can only hope that something serious comes out of the whole exercise, but skepticism is more than justified.

The single most important recommendation formulated by sir Parker, in my opinion, is this:

The MOD Sponsor should establish a transparent Master Plan for naval shipbuilding that lays out Defence’s procurement plans for each series of naval ships over the next 30 years. This should be backed by “set and assured” capital budgets for each new series of ships. The Master Plan should be reviewed at each SDSR.

The importance of an overarching, long term vision cannot possibly be overstated. What sir Parker denounces in his report is that the Royal Navy’s future is dependent on a series of programmes that almost come out of the blue. There is no master plan, there is no long term vision guiding the succession of studies, assessments and attempts to launch a new shipbuilding programme of any kind.
The result of the short-termism is evident in today’s frankly desperate situation, in which the Royal Navy, at very short notice, has been saddled with 5 OPVs that it didn’t really want nor yet need (the current ones could easily last another decade, as was planned until recently); while at the same time seeing its main frigate programme not only delayed, but broken into two halves, the second of which has no defined shape, role, budget. RFA Diligence is gone without replacement, RFA Argus is very much at risk of ending the same way within the next 4 years, and the future of everything else is still vague and indefinite, subject to the shifting fortunes of yearly budget negotiations.

Ultimately, the current process involves many people and too many ‘hand-offs’. Too many think they have a vote, or even a veto, in the process. Current governance is not sufficiently clear. There is no assured “Capital budget” for a RN project which means programmes are subject to arbitrary intervention and delays adding to cost. Senior Responsible Owners’ objectives and accountability are not always properly aligned. There is a clear system of financial approvals via the Investment Approvals Committee, but the system is not always applied intelligently to ensure that good quality information and early engagement with decision makers results in well evidenced and timely decisions. The result is a lack of empowered project grip.  

Sir Parker talks of “set and assured” capital budgets for the 30 year plan, and this would clearly be helpful, but it is also evidently very complicated. Even just a more flexible commitment would help, however, as it would help the Royal Navy’s struggle to preserve what’s left of the fleet.
The navy itself needs to plan that far ahead, not so much in terms of what the singular ship will look like that far away in time, but in terms of how to retain and possibly enhance a capability. There are, in my opinion, two critical cases in which long term planning is long overdue: one has to do with the role of the MCM, Hydrographic Capability (MHC) mothership expected to eventually replace current Hunt, Sandown and Echo classes, beginning in 2028. The MHC mothership plans have taken, this far, a very far back seat, with all MHC attention going to the payload development and test.
There are certainly good reasons for focusing on the new unmanned vehicles and the new kind and breadth of stand-off mine clearing they enable. It is a great innovation, with all the risks that innovation entails, and until the system is proven the Royal Navy cannot take a final decision on whether the future mothership will be a steel-hulled, multi-role vessel or a novel edition of the super-specialized GRP hulls in use today.

The Royal Navy, however, needs to take a decision quickly because as Type 31 drops down the capability ladder to become a “light frigate”, or a General Purpose vessel, the fields of usefulness of Type 31 and of the potential MHC Mothership begin to overlap.
Without a plan, there is a very real risk that the Royal Navy, within a decade, goes from having no “second line” flotilla to having three classes of second rank ships: Type 31, River Batch 2, MHC. It would be an incredibly bad use of money, because it would leave the high end fleet of escorts short of numbers and capability, while overcrowding the lower segment.
Sir Parker mentions that containerized MCM kit could one day be deployed from Type 31, and while this might well be, the point that needs to be made, very quickly, is what overlap exists between Type 31 and MHC – Mothership. Can they become the same programme? If not, how can the RN make sure that the Type 31, while being “light” is an escort oriented towards the high end of warfare, with MHC covering the low end, rather than duplicating a same set of limited capabilities?
This is how wasteful procurement is born: lack of clarity, lack of long term vision.

The Type 26 itself is already suffering from severe lack of long term vision. The Royal Navy arrived to the Type 26 programme after close to two decades of desperate attempts to get a new frigate programme on the move. Countless efforts began and died without ever generating a single ship, and the last of the big studies had eventually come up with a fleet-wide plan for 10 “C1” high-end ASW combatants supported by 8 “C2”, simpler “general purpose” frigates, with a third class, the “C3” for OPV roles and MHC mothershipping.
Type 26 came out of the killing blow dealt to that tentative long term plan: C1 and C2 were merged into Type 26 and their cumulative total was reduced to 13, with any C3 equivalent deferred to a vague future.
Then, just a few years into the Type 26 programme, the Royal Navy has been effectively kicked back to a C1 and C2 situation, where 8 Type 26 are supposed to be the C1 element and the Type 31 the C2.
This is an example of catastrophic long term planning failure, and the Type 26 now arguably suffers of design imbalances caused by having to be the “one and only”. The Type 26 has been designed with extremely long logistic endurance, a vast defensive armament spread in two different areas of the ship, a very large mission bay and a Chinook-capable flight deck, and thanks to the MK41 it has the potential to be very well armed as well (overlooking for a moment the fact that right now she is far more likely to have empty cells than filled cells, again for lack of clarity on the future and cash shortage). Was all this necessary in an ASW-roled escort which, by virtue of its role, would spend most of its time in task group? They are all very helpful attributes, but being in task group means having relatively easy access to extra firepower from the other vessels; access to fuel and stores replenishment; aviation support.
Currently, the RN is facing the prospect of having a large, multi-role ASW vessel inside the task group and a cheap, light frigate doing solo deployments. One is left to wonder if it wouldn’t make more sense to have built a somewhat simpler ASW escort, more rationally thought out for Task Group roles, and a capable “global combat ship” as supporting element, designed to be a capable “solo player”.
Imbalances caused by lack of long term clarity, again.

Another area that needs long-term clarity is the amphibious capability, left in disarray by the loss of HMS Ocean without replacement, which damages very badly the UK’s capability in the sector and imposes a hybrid use of the new aircraft carriers, under the acronym CEPP, for Carrier Enabled Power Projection.
The long term solution, if a realistic amphibious capability is to be retained, is to replace the current LPDs with LHDs, combining aviation spaces with well dock and large landing crafts. But this will be extremely complex unless a coherent plan is worked out well beforehand and the government endorses the requirement. As of now, would you be willing to bet any money on the LPDs being replaced at all…? I would be very torn.

The lack of a long term plan inexorably makes it almost impossible to sustain the shipbuilding sector. How can a serious industrial and infrastructural project be put together if there is not a realistic idea of what it is that the Navy will buy, how it will do so and when? Who could ever seriously invest in shipbuilding if the only thing somewhat assured is that a few frigates will, indeed, one day be built again, while everything else might simply be replaced by vessels built abroad, if not by nothing at all?
A long term plan is desperately necessary. Everything depends on such a plan, and on decisions to be made. If we look ahead, we see that a shipbuilding plan for the surface fleet includes:

-          3 large Solid Support Ships, probably close to 40.000 tons each, to be built between 2020 and 2025
-          8 Type 26, between 2017 (hopefully) and the 2030s
-          N Type 31 between X and the 2030s
-          N MHC ships, to be defined, from the late 2020s onwards

The LPDs should enter “replacement age” around 2030 – 2032. Now that they alternate in and out of service in 5 year intervals their useful life might be effectively stretched out, but their lack of aviation facilities and overall insufficient troops and vehicles capacity, in light of the loss of Ocean, suggests that a replacement is needed sooner rather than later, so the carriers can eventually concentrate on being carriers, rather than LHAs. Depending on the choices that will be made, building the LHDs would also help sustain the whole shipbuilding sector.
By 2039, the Type 45 will all have gone out of service too, unless their 25-years life is extended. The Royal Navy is currently planning to have them gone by 2039, taking the last MK8 Mod 1 guns with them (there is currently no money for ever retrofitting the 127mm gun on Type 45).
Depending on how the government wanted / was financially able to proceed, there is no real shortage of work: these programmes often overlap, suggesting that for many years there could be a relative abundance of orders. Assuming all programmes eventually start and that ships are not procured abroad. And this is what the strategy needs to say.
In the early 2020s, the RFA Argus question will resurface as well, and a successor to RFA Diligence is highly desirable, so there is in theory a need for a couple of large civilian ship conversions or new builds, if the government is willing to endorse the requirement.

The Venator 110 is sir Parker's idea of what a Type 31 base design could be. Hard not to agree with him, especially since the two BAE alternatives seen so far, the Avenger and Cutlass, have little good to offer, particularly the former. 

 
The Royal Navy desperately needs a long term plan for weapons, too. VL or canister? Type 23/45 would need the latter, Type 26 the former, Type 31? Land attack? Anti-ship? Currently, only confusion is apparent. 

All decisions about the future of the shipyards can only be taken if there is a long term master plan upon which assumptions and plans can be built.
If the three MARS SSS ships were built in the UK, in Blocks and Super Blocks, even Rosyth could have a future as the yard of assembly. As of now, Rosyth does not have much of a post-carriers future, with the Goliath crane already expected to be sold once the work on the flagships is over and all that remains is nuclear submarine dismantling and, maybe, the carrier refits over their service life.
A decision to have the SSS built in the UK could change the situation entirely, and the LPD replacement could slot on the back of the three ships (with a bit of a gap in the middle, admittedly, but probably manageable).

The recommendation to assemble the Type 31 away from the Clyde is a political hot potato. In some ways it is highly desirable, in others it is a problem. The SNP will be given something to moan about if the Clyde does not assembly the new frigate. On the other hand, if a yard down south does the job, the SNP can be told, much more credibly, that if they play their independence stunt, the flow of work for the yards will dry up and construction will move south.
It is also evident that trying to built two different frigate types at the same time in the same yard could cause all sorts of problems, including the transmission of delays from one programme to the other whenever something does not work as intended. It might be reasonable to assume that BAE systems will attempt to craft out a plan to use Govan and Scotstoun differently, perhaps assigning a frigate type to each site. What will happen with the Type 31 is, at this moment in time, anyone’s guess.

The exportability bit is the one that leaves me shaking my head. It is hard to imagine that Type 31 will turn out a great export success. The market is already quite saturated with “cheap” warships which come with extremely good capability and a very heavy load of weaponry. If the Royal Navy insists on its usual trend of trying to contain cost by shredding sensors and weapons rather than adjusting building standards and other areas, the Type 31 will never sell. Look at the ships that are being sold, or seriously considered by this nation or that: they are capable vessels. They have probably cut corners somewhere, otherwise they would cost more, but they carry sensors, they tipically have an ASW capability, perhaps not always exploited by the customer, but present. They are heavily armed. The MEKOs sold to Algeria, for example. Or the Aster-armed ships recently sold in the Gulf.
Extremely well armed and cheap vessels from Russia and China are an increasingly attractive proposition.
And there is now a strong political pressure on the US Navy calling for the design of a new “small” surface combatant to build in place of the LCS-derived Fast Frigates in the 2020s. If such a ship was to emerge, it could deal the killing blow to any Type 31 export hope before Type 31 even becomes a thing.
For a variety of good reasons, it is very hard to imagine the Type 31 actually selling, especially if it is built as something which is little more than an OPV.

The Royal Navy needs to get a Type 31 which is actually useful at escorting. It also needs, possibly, to reconsider exactly how Type 26 and Type 31 will be used to cover future requirements. Perhaps it makes more sense to have Type 31s with variable depth towed sonars doing Task Group escort work and Type 26 in solo deployments.
The Royal Navy needs escorts that are credible and that respond to the two greatest dangers out there: air and sub-surface attacks. Type 31 must focus first of all on this simple truth, like the French FTI “intermediate” frigate is doing. The lower end constabulary tasks should not be a design driver, nor, arguably, should they be the Type 31’s concern. What kind of role will the MHC mothership be able to play in that area? Knowing it in good time is fundamental.

The Marine Nationale has been clear all along about what it wanted out of FTI: a ship with capable AAW defences and a good ASW capability, at a lower cost than that of a FREMM. The Type 31 should follow the same path rather than venture in "General Purpose" non-ASW land which will never deliver what the navy effectively needs from its escorts.  

Two other recommendations stand out to my eyes: that the MOD and Navy should be more intelligent buyers of ships; and that a marine design centre of excellence is missing from the picture.
There is a bond between the two things, I feel: the Royal Navy needs to be part of such a design centre of excellence, and it must probably have its own design office inside the organization. Much, if not all, of the Royal Navy’s internal know how and capability in designing warships was lost years ago, leaving the service more or less completely in the hands of industry. This was supposed to save money, but it has probably generated more trouble than benefit.
A Navy able to design its own solutions is a more capable and intelligent customer by default. It will not need to buy the solution to every problem: it can design it and then have it realized. The Italian navy is currently kicking off a major shipbuilding programme building 7 PPA, “light frigates” that will complement the FREMMs and replace everything from two of the old Destroyers down to the current OPVs. The programme also includes a massive and very capable LHD and a supply ship. The cost of the entire programme is lower than the Type 26 alone is expected to cost, and this is extraordinary.

Only 2 of the 7 PPA will be fully equipped with sensors and weaponry, at least initially (torpedoes, towed sonar, Aster missiles, Teseo SSM, 127mm, 76mm CIWS), with a few more having an intermediate fit including 76mm CIWS on top of the hangar, 127mm gun and Aster missiles and the remaining having lighter sensors fit and only the guns, with no Aster. But all come with significant innovations in their design, from the bow to their high speed, from the mission spaces under the flight deck and amidship to the new fixed-face radars to the impressive two-man "cockpit". 

One of the “secrets” of the current Italian shipbuilding programme is that the new ships have largely come out of the work of the Navy’s own design office. Industry is involved, of course, but in a very good way: the new ships introduce a large number of new systems (a new CIWS 76mm turret, new IRST, new radars, new towed sonar, a modular and multi-mission design, an innovative wave piercing bow for very high speeds (PPA is meant for 35 knots speeds) and others) designed by the nation’s industries. Why the UK can’t put together something as ambitious? Why has the Type 31 to be affordable only through being a depressingly low capability hull?


The long-term shipbuilding strategy for the UK must include a real centre of excellence in shipbuilding design, and the Royal Navy probably needs to have its own office inside. Shoulder to shoulder with industry, but with doors that can be locked when the moment calls for it.

The incoming aircraft carriers: more than just carriers


HMS Queen Elizabeth will be officially named in a ceremony planned for July 4, and the ship will be pulled out of dry dock soon afterwards, so that a major, historic milestone is quickly approaching. The importance of these new carriers for the Royal Navy goes beyond the "simple" regeneration of naval fixed wing aircraft capability, expanding well into the amphibious domain. This truth has not yet been fully understood by many external observers, which continue to focus on impressive, but far less relevant aspects of the program. In this article i want to take a look at the current situation and explain how the carrier's air group is taking shape.
There is still confusion about what role the new aircraft carrier(s?) will have in the Royal Navy once they enter in service. Of course there’s realistic worrying about having enough aircraft embarked, both because doubts reasonably remain on how the RAF will utilize the aircraft (which it owns) and because the UK’s order for the F-35B is currently standing at 48, down from what once was an ambition for 150, then 138 from roughly 2006 onwards. More orders might be made in the 2020s, but no one is willing to bet on those as of now, and actually even the planned buy of 48 has to pass through the SDSR 2015 and multiple successive Gate points, which might actually reduce the number even further. I will try and provide a more in depth explanation of what is happening.

More than anything else, however, in this article i want to explain just how important the new carriers are for the future of the british amphibious capability as well. This is a key aspect, which needs to be cleared, because getting the carriers wrong would not only end the Fleet Air Arm's fixed wing branch once and for all, but also deal a very heavy blow to the Royal Marines. 




The aircraft to be carried
  


The Joint Combat Aircraft program, which is the purchase of the F-35B, is currently sitting at its Main Gate 4 decision point. This major development was announced a few weeks ago, with Philip Hammond releasing an interview to the BBC and with several reports appearing on the press. This main gate reportedly covers the purchase of 14 F-35B plus spares and infrastructure investment, not better specified yet, to support the whole planned fleet. It was understood that a formal announcement in Parliament would follow, but so far this has not happened. 

Of course, this silence has been interpreted by some as a way of the british government to distance itself from the F-35B, but this is absolutely false. There was never going to be a big contract signed at once for the 14 jets, but only an internal budget-setting exercise to cover purchases that will happen over several years, in different production lots, over multiple contracts signed through the F-35 Joint Project Office and the Pentagon.
The idea seems to entail receiving 14 F-35B by 2018, in order to form the training fleet in Beaufort and stand up the core of the first operational squadron (617 Sqn RAF). The UK has already ordered four jets, three of which are instrumented test aircraft destined to the soon-to-stand-up OEU Sqn (XVII Sqn RAF) on Edwards AFB, in the United States. BK-1, BK-2 and BK-4 are the instrumented aircraft, while BK-3 is not instrumented and will join the operational or training fleet.
The training fleet (expected to eventually number some 6 aircraft, judging from earlier plans) will be based on the US Marines air base Beaufort, where, in 2016, 617 Sqn will officially stand up again (the squadron disbanded on 1st April this year, with the Tornado GR4). The core of the squadron will be trained in America, before transferring in the UK, in Marham, by 2018.

If this plan is respected, the 14 aircraft the UK will soon be ordering will have to be spread at most on LRIP 8, LRIP 9 and possibly LRIP 10. This is based on the roughly 2 years it takes from contract finalization to delivery. The UK has long been expected to order 4 F-35B in LRIP 8, and on March 25, 2014, the Long Lead contract for the LRIP 9 has been signed, including materials for 6 F-35Bs for the UK. That leaves 4 more to be ordered later in LRIP 10 to make up the total of 14. The aircrafts in production lots beyond the 10th would only be delivered in 2019 and in the following years, as roughly two years separate the signing of the final production contract and the delivery of the airplane. 
In early march there was also the news of a 7 million dollar contract signed for site-activation activities for starting to make RAF Marham the main operating base for the british F-35Bs. So, even if without a formal announcement in Parliament, the acquisition programme is indeed going on.

RAF Marham is expected to be built up to include a full Integrated Training Centre, which means the UK plans to step away from training in the US to do things domestically. The ITC won’t begin operations before 2019, but we can expect investment for it to begin soon enough, if the plan does not change. The UK appears interested to gain money by selling training services in its ITC to other European customers of the F-35. Mainly, talks are ongoing with Norway. A recent agreement is pretty clear in foreshadowing the idea at the base of the collaboration: Norway’s state-owned AIM hopes to do depot maintenance for the engines of the british F-35 fleet. AIM signed an agreement with Lochkeed Martin and Pratt & Whitney in april 2012 to secure its role as a depot maintenance hub for the F-135 engine, and now wants to secure a long term gain, exploiting such role.
Norway, in exchange, would send its pilots training in the british ITC, instead of sending them all the way to Luke, in the US. 

It has been announced in Parliament that the F-35s will not wear squadron specific colors, but only the low-visibility grey national markings. Hope there will be a rethink...

Or at least, something like this, in grey. Image @ Al Clark, janetairlines.com
 
Depending on how things go with the announced new Defence White Paper in Italy, UK and Norway will probably have new talks with Rome about expanded cooperation. The Italian FACO in Cameri is expected to become the regional MRO facility for the F-35, which means doing depot maintenance and upgrades installation for the aircraft of the USAF-Europe as well as those of all other countries that will buy in.
As of today, a single MRO centre is expected in Europe and in the Mediterranean area, so that the options will be restricted: UK and Norway will have to choose between Cameri and the MRO facilities in the US.
Italy could collaborate with the UK by co-financing Meteor missile integration (discussions ongoing) and by sending its personnel to the UK for training in the british ITC, instead of sending people all the way to Luke and Beaufort in the USA. In exchange, the british F-35Bs could have their depot maintenance done in Cameri. Finding a fair agreement with Norway will be tougher, as Italy has already agreed to have its F-135 engines serviced by the Dutch, which are getting their F-35s assembled (and in future maintained) in Cameri in exchange.

As of October 2013, Lockheed Martin expects that the UK, in 2018, will have taken delivery of some 17 aircraft, with 9 based in Marham with 617 Sqn, 3 in Edwards with XVII Sqn, and 5 more as training fleet in Beaufort. 

The expected 2018 situation for the F-35, as of October 2013

In terms of UK-specific trials, work to develop and validate the Shipborne Rolling Vertical Landing tecnique has resumed after being stopped over 2010 and 2011 when the plan was temporarily changed in favor of acquiring the C variant of the F-35. Work is now ongoing with computer simulations in Warton. SRVL will improve performance in hot climates, produce less stress on the vertical lift system and add thousands of pounds of useful payload at recovery. The F-35B is to be capable to land vertically with some 5000 pounds of unused fuel and ordnance, which is a value far higher than the Harrier's and close to the 6000 pounds carrier bring back of the old F-18 Hornet, but it could prove insufficient were the aircraft to be heavily loaded with, for example, Storm Shadow cruise missiles that the UK hopes to integrate in the future. 
SRVL could add some 2000 lbs of additional payload margin, which would do wonders to enable safe operations with heavy configurations. 

It has also been reported that it is likely that up to three F-35Bs, including one of the british ones, will do their first flight across the Atlantic in the Summer, to participate at the RIAT and Farnborough airshow. 


Beyond the F-35B

The CROWSNEST program for the replacement of the Sea King MK7 ASaC has finally started to roll, and the In Service Date has been moved closer in time, to reduce the gap that will be formed when the Sea King goes out of service.


The Merlin HM2 fleet will be fitted with a palletized radar suite enabling the helicopters to take up the role of Airborne Surveillance and Control platforms. 


The Merlin HC3 and HC3A of the Royal Air Force are going to be navalized and transformed into amphibious support helicopters, under a contract which has finally been signed. It will however take time to have the whole fleet of 25 machines fully ready.


Last, but not least, the Apache attack helicopters of the British Army are now being all fitted with additional naval features, including an emergency flotation device, to enable them to serve on board of warships in a safer and more effective way.


Details of these and other helicopter programs can be found in this detailed article.


A key role in amphibious operations

A factor that not always is kept in mind when talking of the new carriers, however, is that they will not just be fundamental to restore the british capability to deploy airpower at sea and from the sea, but they will also be absolutely vital for ensuring that the amphibious capability of the UK continues to exist and to respect the levels set by the SDSR 2010.
The defence planning assumption is that the Royal Navy has to be able to land a Royal Marines commando group with related vehicles, helicopters and supports, sealifting and then landing a total of roughly 1800 men.
This is only possible using one LPD of the Albion class, one LPH and the three remaining Bay class LSDs. The LPD is fundamental because it brings to the party the command and control facilities and the most part of the landing crafts available to the group, as well as vehicles and substantial amounts of stores. The LPH is fundamental as it carries the most men and almost the totality of the helicopters. The LPD and the LSDs have very limited aviation facilities, and no hangar, so the LPH is absolutely vital in order to ensure that the battlegroup can be supported from the air and moved by air.
The LSDs transport men, boats and landing crafts, bulky materials, normally at least one army workboat, mexeflotes and a lot of the vehicles and stores of the group.

None of these components can go missing, otherwise the whole force is in serious trouble. The 1800 men figure is not casual: it is quite clearly calculated on summing the capacity of the vessels remaining in force.

LPD: 305 men
LSDs: 356 men (x 3)
LPH: around 600   

The Royal Navy has two LPDs, but only one is in service at any one time, following the SDSR 2010. Currently, HMS Bulwark is in service and acting as the flagship of the fleet, while HMS Albion has been de-stored, disarmed and tied up in Devonport, in the amphibious center now known as HMS Tamar, where it is languishing, sealed up and fitted with controlled humidity devices to preserve her. The plan as of now is that in 2016, when HMS Bulwark hits refit time, HMS Albion will be re-activated, and the two ships will swap places.

The LPHs are also two, as of now, but again this is virtual only: HMS Ocean is about to come out of major refit, while HMS Illustrious has been working as LPH / Commando Carrier in the meanwhile.
HMS Ocean will be back into action soon enough, but that will be the end of HMS Illustrious, as she will be decommissioned.
HMS Ocean is more or less just air assault. It can lower a pontoon in the water at the back that serves as a steel beach. Light vehicles can drive down a ramp and use the floating pontoon to board landing crafts, but the LPH carries just a relatively tiny number of small vehicles and trailers (tipically Land Rovers). Other than that, she is pure air assault.

HMS Ocean normally carries just L118 Light Guns, land rovers with trailers and some BV206s
This photo of HMS Ocean during operation Ellamy shows the steel beach pontoon folded up and stored on top of the structure protecting the vehicle ramp going down from flight deck to vehicle deck

HMS Albion and HMS Bulwark are LPDs with an alarmingly low capacity for soldiers (only about 300 unless you start being less permissive with the space each man has, but that is not good for months-long deployments abroad which are now the norm for amphibious task groups including the RN's RFTG), and the LPDs offer limited air facilities, with no hangar.

The Point-class RoRo strategic sealift vessels are fundamental to carry stores and lots of vehicles for the support of the landing force, but they have no accommodation for troops, and can only carry vehicles and stores meant to be loaded ashore later, when the beach head is secure.
Besides, the Points are down to 4, from the 6 they used to be, as two were released from MOD service, despite the SDSR 2010 document promising specifically that all six would stay. 


The Point class Ro-Ro ships carry huge amounts of vehicles and stores
The LSDs used to be four, but the SDSR 2010 saw Largs Bay withdrawn from service and sold to Australia. Of the three that remain, one is permanently deployed in the Persian gulf (right now it is Cardigan Bay) to act as mothership for the MCM force based in Bahrain. Cardigan Bay has been fitted with a prefabricated shelter on deck, as a hangar of sorts, and has been recently assigned a permanent Lynx helicopter flight. It has also now been equipped with a Sea Eagle UAV system, which is entering in service in this week.

The end result is that the daily reality of the amphibious force is the ability to sealift and land a smaller force than the 1800 promised in the SDSR. The vessels can of course be crammed with more men for short periods of time (up to 700 on the LPD and LSDs, and over 800 on HMS Ocean) but this is not a very realistic capability, because it is not accompanied by an increase in stores and vehicles carried. And anyway, the men will start finding the crowded vessels unbearable very quickly, in a matter of days.

For a normal, yearly deployment such as Cougar 13 this year, the Response Force Task Group spends months at sea, so the ships are preferably lightly loaded in terms of men. The already mentioned Cougar 13 is a good example: 42 Commando, the formation currently at high readiness, did not embark whole on the ships. For example, Lima company was flown out to Albania ahead of the rest of the formation moving on the ships. The occasion was exploited to conduct mountain training.
The company then traded place with Kilo company. The end result is that the amphibious battlegroup pretty much never was fully present at once on the ships. Aside from the training requirements dictating the independent movements of companies, the availability of only 2 Bay-class LSDs has obviously part of the responsibility.

The big problem on the horizon, however, is the planned decommissioning of HMS Ocean, without replacement, in 2019. The task force however obviously continues to require a big platform for the amphibious assault helicopters and for the transport of hundreds of men, and this is where the carriers step in.
Since the platform for helicopters is going without a direct replacement, the Queen Elizabeth-class carriers will have to be hybrids. It is not a choice, it is an unavoidable necessity. And hopefully the new ships can pull such a mixed role off. They will be, in fact, closer to America than to a supercarrier. The Royal Navy and Royal Marines will need to be able to cram hundreds of marines into Queen Elizabeth, along with some stores and perhaps some air-liftable vehicles and L118 Light Guns too. Helicopters, including Chinook and Apache, will have to be carried. And in addition to that, at least a squadron of F-35B, if airpower is to be finally brought back to the fleet.
The fact that the new vessels are so large gives hope that the hybrid role can be covered well, despite the design of the ship being clearly centered on delivering fast jet sorties, not to land and support troops ashore.

The Royal Navy has finally formally recognized the need to operate the new carrier as a hybrid in the SDSR 2010, with the public description of the Carrier Enabled Power Projection concept. A surprisingly detailed note was shown in the SDSR fact sheets, when it was described that:



We will plan concurrently to operate a mix of helicopters as well as Joint Strike Fighters from the carrier. This will include up to 12 Chinook or Merlin transport helicopters and eight Apache attack helicopters. The precise mix will depend on the mission.



There are obvious challenges to be faced and won, if this has to work. Embarking and employing simultaneously jets and helicopters for amphibious assaults is not at all easy. The US Marines do it routinely on ships smaller than the QE-class carriers, but specifically thought all along for such use. And anyway, the fixed wing component they use in such cases is normally made up by just 6 Harriers (possibly growing up to 10 F-35B on the new America LHAs). Obviously, they enjoy the formidable cover offered by the US Navy supercarriers: the UK doesn’t, so it will have to embark more jets to give the task force proper cover.
A key difficulty is finding suitable space for the many hundred men needed. Fast jets and helicopters require a large number of maintenance and deck personnel, and having to add hundreds of Royal Marines means needing lots of accommodations.
The needs of the Royal Marines are different from those of an aircraft ground engineer, besides: the Marines need space for their weapons and kit, and also need to be accommodated in spaces properly dimensioned and located around the vessel: they need to be able, once kitted up and ready to go, to walk easily up to the flight deck or to the ship’s boats, to board landing crafts and helicopters.

Fortunately, a secondary role as Commando Carrier was always part of the aircraft carriers design, so that there are wide corridors and spaces for the embarkation of troops. The December 2013 issue of Navy News includes one of the very first, rare mentions of these arrangements. There are accommodation quarters for “easily” 250 men, with wide assault routes. 250 men, however, will not be enough, and it will always be a struggle to balance embarked forces and air wing personnel numbers and accommodations. 
The Marines will probably be able to board boats and landing crafts from the boat boarding area in the stern of the carriers, which can be accessed via stairs going down from the hangar deck. It has not yet been cleared whether the boat areas of the carriers feature spaces and cranes sufficient for the embarkation of LCVP MK5 landing crafts. 

This photo, courtesy of navyrecognition.com, shows well the stairs leading down to the boat boarding area. A crane is fitted to a sponson just beneath the flight deck level, and it could be useful to move stores to and from boats coming up behind the carrier.

This image from earlier phases of the building process shows (evidenced in blue by me) one of the large openings in the sponsons for the launch and recovery of ship's boats.

Other problems come from trying to operate large number of helicopters as well as fixed wing jets. The design of the deck of the carrier is being developed and refined with these conflicting needs in mind. As of September 2013, the Royal Navy was reportedly trying to carefully design the deck to achieve 10 helicopter ops spots.

If the “hybrid carrier” works, we will have a high value vessel which will be forced to sail far closer to the shore than we'd like it to. It is true that the Royal Navy is planning for escort ships sporting flight decks big enough to easily accommodate even the Chinook (Type 45 already in service, and even the new Type 26 frigate is planned to have such capability), which could be used as forward refueling sites to allow the carrier to stay further back and still fly troops ashore by helicopter, but the feasibility of such concept is questionable.

At least, even with all the conflicting requirements crammed together, all the three key capabilities of any naval / amphibious task force will be present: fast jets for air cover and support, helicopters, troops.
But if it does not work, we will have a disaster, with amphibious capabilities badly maimed and with air strike capabilities set to remain dramatically limited by the very small number of F-35B that are going to be purchased. In practice, the gap in embarked fixed wing aviation would be closed (at least in part), but a gap in amphibious rotorcraft capability and simply in amphibious troops lift will open, making the whole task force just as crippled. It would be a case of swapping  a problem for another.

The next time someone asks what the carriers are for, or wonders why they are so big, remind them that they are very much needed, and that their huge sizes are to be blessed, as smaller vessels would never be able to approach the kind of mixed role that lays ahead. And no, there is no guarrantee at all that building smaller carriers would have been made it possible to also build dedicate LHDs. It is pretty likely that the cost of more numerous, relatively smaller ships would have been equal, if not higher, especially considering that the CVF vessels have very small crews. More, smaller ships would have almost certainly required more personnel to crew and support them, and personnel is exactly what the Royal Navy post SDSR does not have.

It is painful to watch two fine LHDs of the Mistral class being built for Russia, knowing that having at least one such vessel in Royal Navy service would solve much of the problem, and represent an excellent boost in capability. But I’m not going to spend much time daydreaming: the deal will go ahead, as the money is too much and too good to pass up. Paris is highly unlikely to truncate the deal, and even if it did, the MOD has no budget to procure the vessels. Not one, and certainly not both. Besides, the ships would need some serious work done to remove the Russian kit and have Royal Navy equipment fitted in its place, which would make the purchase even more financially challenging.
Even in the best case scenario, the problem won’t be solved until HMS Albion and HMS Bulwark are replaced, most likely by large LHDs. Until then, the Royal Navy will have to make do.

This leaves the big question: will both carriers enter in service, or will the Royal Navy get only one?
If both carriers are kept, but one is held in reserve, mothballed like Albion, only coming out of its "coma" every six years to replace the sister as she goes into refit, the problem remains: perhaps a major operation (but it has to be really big) would see the second hull hastily reactivated (ala HMS Intrepid back in 1982) with the fleet then faced by the decision of perhaps using one as carrier and one as LPH, so only one of the two has to sail close to the shore.
However, this neat separation would probably be judged unworkable because if either of the two ships was damaged the task force would lose most or all of either air power or amphibious helilift. Probably, even with both ships in the task force, fast jets, Marines, helicopters and stores would still be split among the two in roughly equal terms for prudence.
In normal years and normal operations, the RFTG would still be faced with the problems coming from having a single flat top for two roles.
The above situation (with one carrier active, one tied up in port with sealed doors and Controlled Humidity kit installed to try and keep it together while it languishes in port for years on end) is probably the best outcome we can realistically hope for in 2015. Which is a bad scenario, but... not the worst of possibilities, at least.

If both ships are regularly operated, side by side, the RFTG could sail (most of the time) with both carriers in the group, one working as LPH, one as carrier (in "peacetime". In war, the split described before would probably still be preferred). This would cost more in terms of money and manpower, and i'm not optimistic. I don't think we are going to see it happening, sadly.
Even if we do see it happening, there will still be periods in which only one of the two hulls is available, with the other in refit. So the problem still pops up, but at intervals.

So, the Perfect Solution is already out of the window, and it has crashed to the ground already years ago: the problem won't be eased until Albion and Bulwark are (hopefully) replaced with (hopefully) two LHDs, allowing the carrier to act as a carrier, while the large LHD carries both the large landing crafts and the helicopters, and more men.
The question is whether or not the Good Enough Solution (hybrid carrier / assault ship ala America but with greater number of fixed wing aircraft embarked, operated and supported) is achievable and workable. Considering that QEC is considerably larger than America, i think it should be achievable. But it is far from sure. It depends on how the spaces inside the carrier have been configured, on accommodations, on lots of other factors.

The worry here is that this reality has apparently been fully grasped only in 2010, with the emerging of the famous Carrier Enabled Power Projection acronym, which includes this double role problem (along with other things less directly connected to the carrier, such as MARS and CROWSNEST). My hope is that proper thinking about this problem was actually going on from many years earlier inside the RN and the design team which worked on the carriers. I hope they actually worked on the "Commando Aircraft Carrier" (which is something different from both the Commando Carrier and from the Aircraft Carrier) from much earlier, and that 2010 only marked the date in which the Royal Navy publicly admitted that, with no replacement for Ocean on the way, QEC would have, in a way or another, to do it all. Some provisions for a secondary LPH role are understood to have been into the requirements all along, and i hope they have provided a good base to build upon.

If it wasn't so, and planning for it only began in haste in 2010, the carrier design is probably going to struggle in taking the full burden of the requirements on the horizon because the time for making adequate adjustments was allowed to pass and go.
In a way or another, the concept must be made to work, because there is no real alternative in hand’s reach. What is clear is that the carriers are definitely needed. Next time someone asks, you’ll know how to reply.
