NSS and SDSR 2015: My review of the military context

The National Security Review and Strategic Defence and Security Review 2015 has been published, rather late in the day but nevertheless published. One immediate difference from the 2010 reviews is that both the National Security Strategy (NSS) and the Strategic Defence and Security Review (SDSR) are combined together. That makes a big difference, but I’ll deal with the strategy part in a later post. First, the military (which forms the defence part):

The Royal Navy:

* Senior service in the NSS and SDSR 2015 stays almost as expected.
* Major ships in surface fleet stay at the small number of 19. But only eight/8 x Type 26 Global combat Ships will be ordered, the anti-submarine variant with Sonar 2087. Five more will appear later, but possibly more with a revised version for “General Purposes”. As many point out, this goes back to the original C1 and C2 variants. Would we thus get more than thirteen/13 type 26 frigates? What exactly will this GP variant be like? Will it have Mk41 Vertical Launch Silos (VLS)? Or are they copying my old idea?
* The graphic shows “up to 6 Patrol Vessels”. Batch 2 River-Class Frigates for sure, plus HMS Clyde, plus the two more that the document (page 31) that will be ordered. I suspect these two/2 additional vessels will also be Batch 2 River-Class? So goodbye to the Batch 1 Offshoere Patrol Vessels (OPV). All seems really good–These can help patrol the Caribbean to some extent and release Royal Navy and Royal Fleet Auxiliary (RFA) vessels for other more pressing commitments. It well, also means the Scottish workers have more secured jobs for a while. Lucky them.
* No mention of other patrol vessels, especial the Gibraltar Squadron. Will there be any change?
* Only twelve/12 Mine-counter measure vessels are specified in the graphic, down from the fifteen/15 the Royal Navy has at present. No mention if these are the Mine countermeasures and Hydrographic Capability (MHC) future variant, though they are likely to be. That’s ok but only if they can extend their reach to the present commitments–the MENA area–or possibly elsewhere.
* Goodbye HMS Ocean. No mention in the graphic or elsewhere. Instead, “We will enhance a Queen Elizabeth Class aircraft carrier to support this amphibious capability.” That, as I and many others point out, is not a practical use of the QEC but well has to be.
* The LPDs and LSDs will stay, ok.
* No mention of the Point-Class Ro-Ros, but they will likely stay.
* No mention of the Merlin HM4/Mk4 variants, oh wait, they put that under the Army graphic. Typo or just saying it’s Joint Helicopter Command (JHC) controlled?
* Royal Marines with Arctic capability. Well, not exactly new; they have operated in Norway for a long time.
* Six/6 Fleet Tankers. Is this four/4 Tide-Class tankers plus the two/2 Wave-Class fuel and support tankers/support ships? Will the Wave-Class ships be replaced in the distant future? Ok, not a worry.
* Three/3 Fleet Solid Support Ships. At present it is RFA Fort Victoria, RFA Fort Rosalie and RFA Fort Austin. Will Fort Rosalie and Fort Austin be replaced by newer Solid Support Ships, again built in South Korea?
* No mention of a replacement for RFA Argus and RFA Diligence. So sad though you did say it it was to be considered. Liar.
* Likely or most likely no change in the number of Merlin HM2/MK2 ASW/ASAC helicopters. Which you know, means a tight Tailored Air Group (TAG). Boo…
*Type 45s may be part of a future Ballistic Missile Defence (BMD).
* Not forgetting the Queen-Elizabeth Class Carriers. Still no confirmation how they will operate, especially with HMS Ocean going away. The TAG is questionable even with the 138 F-35B order which will arise only in the distant future. There are still questions regarding the order. For example, this report says “It means the UK will have 24 F35 Joint Strike Fighter aircraft available on its two new aircraft carriers by 2023.” Does that mean 24 on one operational carrier or 24×2 = 48 on both carriers? Let’s take it as 24 on HMS Queen Elizabeth. What about the 138-24 others (besides OCU and OEU?) As Justin Bronk points out, could they be the A version?
* Of course, Successor-class, that is the SSBNs will be procured. The submarines that cannot do anything.

British Army:

* The Army 2020 model is no more; it is Army 2025. Instead of the austerity-linked but nice plan by General Sir Nicholas Carter (see this), the Army 2025 plan alters the Reaction and Adaptable Forces. Now there will be two/2 x Armoured Infantry (AI) Brigades, down from 3 from the original plan and a change from the typical division size. Wait, two/2 “Strike Brigades” that that could quickly deploy anywhere with independent logistical footprint.
* Strike Brigades?! They want to draw in the 589 Ajax (SCOUT SV) Brigades to form these brigades. But Ajax was to be for the original 3 AI brigades, not playing with a new fantasy fleet concept. What will these Strike Brigades consist of? Say one of the existing AIs and one brigade from the Adaptable Force (AF), maybe 7th Infantry Brigade. What else besides Ajax? Mechanised Infantry Vehicle (MIV) formerly UV, formerly FRES UV. Ok. But what else? How on earth are they independent in terms of logistics? And if you need to deploy a division, will the Strike Brigade (single) become a AI?
* A further question: What happens to the third Challenger 2 Armour regiment with these Strike Brigades? Will the disband/stay in suspended animation or will they be re-organised into the two other AI brigades? Good that Challenger 2 LEP will continue but well tank’s gun is outdated.
* Warrior CSP will continue–will all the six/6 Armoured Infantry battalions get the CTA 40mm gun?
* Upgraded helicopters–expected, nothing new.
* “Two innovative brigades comprising a mix of Regulars and specialist capabilities from the Reserves able to contribute to our strategic communications, tackle hybrid warfare and deliver better battlefield intelligence.” From the AF brigades? What will these be? MRV-P centred?
* 16 Air Assault Brigade stays but any change?
* Field Hospitals stay in the Joint Force (Command). See below.
* No mention of the Armoured Battlefield Support Vehicle (ABSV).
* No mention of upgrades or replacement for the Defender planes or Gazelle.
* No core mention of MIV and MRV-P and other key projects that will replace soon to OSD assets.
* Of course, the magical 77th Brigade will remain as a soft-power enabler.
* Hey look, Commander Land Forces is now Commander Field Army. Great priority change.

The Royal Air Force

* It gains the most as it did in the 2010 SDSR. Junior Service wins.
* 20 “Protector” RPAS, basically MQ-9 Repear upgraded. Not new, announced before.
* Nine/9 PBoeing P-8 Poseidon, the expensive US MPA, to be based at RAF Lossiemouth. The usual cheers around, and it shows how incorrect Mark Hookham is. But 1) They wont appear instantly; 2) RAF and the Royal Navy have no air-launched Harpoons left so they can’t conduct ASuW 3) UK Stingray torpedoes and MK 11 depth charges need to be integrated onboard. Its “overland surveillance capability” is questionable.
* Amazingly, Sentinel R1, the formerly to-be-scrapped aircraft, will stay on “into the next decade”. Possibly they will help the P-8s or act as interim aircraft until the P-8s reach Full Operational Capability (FOC).
* They “el-cheapo: Shadow R1 will stay on until 2030. Really not bad for a propeller plane that could be taken up be Defender (theoretically). And the UK will get two more of them, bringing the total to eight.
* Sentry E-3 and the Rivet Joint (not Air Seeker!!!) stay on till 2035. Any upgrades darling?
* Hey, you didn’t want to keep the C-130s before. Hey! You are keeping 14 of the J models. Plus still aiming for 22 A400Ms plus just only 8 C-17ERs. Suddenly there’s the money to keep the C-130s? Ok, the Special Forces are really happy. More on that later…
* Along with the P-8s and keeping of Sentinel R1, you get this new drone that “will fly at the very edge of the earth’s atmosphere and allow us to observe our adversaries for weeks on end”. As Beth Stevenson points out, it is likely to be the “Airbus Defence & Space Zephyr high-altitude pseudo-satellite”.
* T1 Typhoons to form additional 2 x Squadrons, but only around 12 planes each, down from the 13-15 as seen in FOIAs like this. It is yet to be seen where they will be based given that RAF Lossiemouth will be choked full of planes.
* F-35s as above. But with the great projected order, isn’t it time to given all light blues and all dark blues to Squadrons and dark blue FAA Squadrons?
* Voyager Fleet: You get Cameron Fore One or PM Force One. Save money, give prestige it works out well. But please UK, don’t abuse it.
* The Future UCAV research project with France will continue. Yay..

Joint Forces (Command):

* Special Forces will get the most high-tech equipment. But with a shrunken active force, you would (still) struggle to get enough people to operate this. More later…
* Will you even have enough reserve special forces personnel?
* Joint Force Command, particularly, PJHQ, will get more stars (my FOIA). With a shrunken force, don’t try a top-heavy leadership. Won’t sound out well with the lower ranks.
* Space Operations Centre–a mouthful. For non-military means as well?
* How much effort will be place on cyber, since it is a Tier One threat?

Larger questions:

* So much of the SDSR and NSS is on equipment. How about personnel shortfalls? Getting women and minorities into the armed forces is only one bit to gain strength. You won’t get enough personnel for these major high tech assets–the carriers, the surface ships, the submarines, the F-35s, the additional Typhoons, the Army units etc. Personnel shortages hasn’t but must be addressed.
* When will the new equipment and assets be ready?
* Buying Yank stuff. Do you have a plan if prices increase?
* Will you really spend 2% of GDP on Defence and ho much contingency money is there?
* Any plans to increase, not alter, the personnel size? Or will you make cuts to unit strengths? No use claiming to have a division-sized force when the companies or battalions are under-sized.
* Will the joint model between departments (not JFC), ie. DFID, FCO, improve?
* How much change will there be for this Joint Force 2025 between now and 2020?

Next up, reviewing the Strategy…

PS: Did I miss anything out?

What you will likely and may not get from SDSR 2015

I never like rumours or hearsay but I guess it’s not harm jumping on the pre-Strategic Defence and Security Review (SDSR) 2015 bandwagon.

What will likely be mentioned (in terms of Strategy and Security):

Strategy:

* Government will mean 2% of Gross National Product/Income (GDP/GDNI) of spending on defence.
* Budget (for maybe just equipment) will rise to rise in real terms – 0.5% above inflation – every year during the Parliament (as stated previously in the July 2015 Budget statement )
* NATO will be the core alliance the UK will work with for eternity (or for the super long term), not the European Union (EU)
* Government will also mean the (oudated) Official Development Assistance aka foreign aid target of 0.7% of GDP.
* Focus will be on core areas such as the Middle East (Daesh/ISIS/ISIL), Africa (North and Central)
* Falklands Garrison will stay with no immediate change
* US will be the main strategic ally
* Lancaster House treaty will continue
* Focus will be on value for money–efficiency savings as MOD budget is not ringfenced–but value for strong output
*Linking to above, people such as the Reserves will play a core role in Future Force 2020

In terms of armed forces:

Royal Navy:

* 2 Queen Elizabeth-Class aircraft carriers will be built
* The Type 26 Global Combat Ship/frigate will be built
* 4 x Successor Ship, Submersible, Ballistic, Nuclear) (SSBNs) will be built to retain the UK’s strategic deterrent.
* 7 x Astute Ship Submersible Nuclear (SSN) Astute-Class boats
* 3 x River-Class Batch 2 Patrol Boats (likely to replace the older 3 Batch 1 boats)
* The Mine countermeasures and Hydrographic Capability (MHC) will be considered to replace current Mine-countermeasure vessels
* Merlin and Wildcat numbers will remain
* The Response Force Task Group (RFTG) annual COUGAR deployments will continue, with either Queen Elizabeth-Class carrier joining the RFTG post-2020.
* Unmanned aircraft, surface craft (USV) and undersea craft (UUV) will form the main R&D projects in the future Royal Navy

British Army:

* Army 2020 will continue with some unit changes and some units changing barracks. All units in Germany will return to the UK.
* Ajax (formerly SCOUT SV) production and numbers will continue and stay the same.
* Warrior upgrades aka Warrior Capability Sustainment Programme (CSP) will continue, except that only 245 of them will receive the CTA 40mm gun/cannon (see this article). That is, not all of the six Army 2020 armoured infantry vehicles will gain the new gun/cannon
* Money will be set aside for the Mechanised Infantry Vehicle (former Utility Vehicle, former FRES UV) and the Multi-Role Vehicle-Protected (MRV-P) programmes.
* 50 Apaches will be upgraded to the E version.

Royal Air Force:

* 20 new “Protector” Remotely-Piloted Air Systems (RPAS) will be acquired, a double of the existing number. Basically, updated version of the MQ-9 Reaper.
* F-35Bs will be purchased.
* Trance 1 (T1) Typhoons will be retained to create additional Typhoon Squadrons for UK Quick Reaction Alert (QRA). Tranche 2 and 3 aircraft will thus be free for air-to-ground operations (that is, Operation Shader) (see this link)
* Sentinel R1 aircraft will be replaced.
* Other Intelligence, surveillance, target acquisition, and reconnaissance (ISTAR) aircraft to be upgraded, except the E-3s.

Joint Forces:

* The range of UK Special Forces will gain new equipment.See this news article
* There will be a Multi-Mission Aircraft (MMA), not just a new Maritime Patrol aircraft. (see again this link
* Cyber defences will be strengthened, and the Joint Cyber Reserve will be a key part of this.
* The 77th Brigade (I put this under Joint since it consider of personnel from all services and civilians from other ministerial departments join it) will be a create part of soft power or mechanisms to stabilise or prevent conflict.

These are some of the top issues and assets you may get from SDSR 2015. What you MAY NOT GET or MOST LIKELY WON’T GET:

Strategy:

* Government will not have spare cash or large amount of spare cash to boost the Defence budget beyond 2% of GDP. It may gain funds from the Treasury Reserve, the Conflict Stability and Security Fund (CSSF). The MOD may not have enough money to contribute to the Deployed Military Activity Pool (DMAP), which is a contingency fund within the CSSF, used to support the UK’s emerging in-year security, diplomatic and aid priorities.
* The UK may not, and has not recently been, the second highly country with the largest number of deployed troops in NATO. This level will unlikely be an issue in SDSR 2015.
* The UK will have to depend largely on the US and France should it find itself in a Iraq (Gulf War I mean) or Afghanistan-style conflict. Daesh seems to creating one. SDSR 2015 may not throw in money or personnel into this.
* Personnel shortages may be addressed but not solved in the short or long-term. It would mean lots of equipment without people to operate. More below.
* Chasing targets like 2% and 0.7% would be lots of changing goalposts and a fixation on money not quality. No change in SDSR 2015 for sure.

In terms of armed forces:

Royal Navy:

* SDSR 2015 will not increase personnel strength so that both carriers will operate simultaneously. In fact, snippets indicate that only 450 more sailors will be added to the Royal Navy’s strength. It might mean that HMS Queen Elizabeth won’t operate at full strength, even minus air group. One carrier at all times will most definitely be in port aka extended readiness.
* There will be no definitely confirmation that 13 Type 26 frigates will be ordered. Mybe there could be, but in “drips and draps”.
* There might be, as there always has been, delays to the Astute SSNs boats coming into service. Same with the never to be used Successor SSBNs.
* HMS Ocean may not or never be replaced as a like-for-like. The Royal Navy will have to depend on an aircraft carrier as a strike carrier and a LPH.
* The Royal Fleet Auxiliary (RFA) eldery ships may not be replaced like-for-like.
* The Royal Navy may only end up with the 3 new River-Class Batch 2 ships and HMS Clyde with the Batch 1 ships decommissioned early.
* The MHC project may be delayed.
* Not change in the Merlin HM2/MK2 numbers, so not enough for ASAC and carrier-based ASW roles.
* 809 NAS may have more RAF pilots than Fleet Air Arm (FAA) pilots

British Army:

* No change to Army 2020 in terms of units and personnel. Big adverse implications for units and the Special Forces–see below.
* There may be some removal of 2*s aka Major-Generals or even 1*s Brgadiers who don’t command units. But the Army may still be top-heavy.
* Army Command will change–Deputy CGGS and Commander Personnel Support Command, but that means more money for top commanders not units.
* Challenger 2 will be updated but may not improved or replaced anytime soon unlike this report. So this report is more likely.
* MIV and MRV-P may not appear in the short term.
* No change in CTA turrets or guns/cannon numbers.

Royal Air Force:

* No large order of F-35B aircraft. The orders may likely be in “drips and draps”.
* AMRAAMs may be kept in the long term and there may not be larger numbers of Meteor missile produced or ordered.
* As noted above, there may not be upgrades for all UK ISTAR aircraft or C2 aircraft such as the E-3 which is critical for QRA an operations.
* RAF may end up with more aircraft and still not solving its manpower shortage. This might affect not just the manned aircraft but the 20 new Protectors.

Joint Forces:

* The MMA or at least MPA will not be the highly expensive yet operational P-8 Poseidon. The yet unknown aircraft may not appear in the short term (say 2-4 years) after it is announced.
* The Joint Cyber Reserve may not likely become a full cyber unit despite cyber threats being a Tier 1 threat as identity in the 2010 National Security Strategy (NSS).
* Special Forces will et their new equipment but with the shrunken Army 2020 and Future Force 2020, the various SF units may not be at full strength.

So there you have it folks!!! We wait the announcement around 1530 UK time 23 November 2015.

The Other Merlin: Merlin HC3/4 numbers

Most people have fallen in love with long serving UK military aircraft like the Harrier, the Spitfire and perhaps the Sea King Helicopter. The Sea King Mk4 (the troop carrying version) will soon leaving active service and will be replaced by the Merlin HC.3/HC.4.

Under the Future Force 2020 (not really SDSR 2010), 25 RAF Merlin HC.3s would be modified and transferred to the Royal Navy’s Fleet Air Army (also see this). Or more specifically, the Commando Helicopter Force (CHF) of, or rather for the Royal Marines. The plan has sort of proceeded smoother than most other post SDSR 2010 projects, with 846 NAS being the first squadron to gain these aircraft and then next, 845 NAS. In fact, 846 NAS just returned to RNAS Yeovilton (HMS Heron) with six/6 of these new helicopters. I believe, as the Defense Industry Daily article says, that there were to be at least seven/7, so maybe one more will join it (more on this below). At around the same time, the UK MOD announced a sustainment contract for both Merlin Helicopters. Some may say this is typical Conservative/Tory PR for their General Election 2015/GE2015 campaign, but you still do need investment to create and sustain helicopters.

The whole new Royal Navy/FAA Merlin Fleet will specifically consist of

…845 NAS and 846 NAS each operating 10 Merlin HC.4s, with five aircraft in the maintenance fleet. Each squadron will operate three flights. 845 NAS will have three deployable, go-anywhere flights, with each flight deploying with four Merlins. 846 NAS will have the Operational Conversion Flight, Maritime Counter Terrorist Flight, and a deployable flight to bolster 845 NAS if required.

Now that immediately seems strange. 10 aircraft per each active medium-lift squadron, but you want 4 x Merlins per flight? That would mean 12 x Merlins per Squadron. I guess the extra 2-4 will be drawn from the five/5 helicopters in maintenance? Or would this four/4 per flight configuration only occur during active operations/wartime? Pro-military people would of course still argue this 20 + 5 configuration is too small. I say it’s not bad consideration the fleet size is smaller than it’s counterpart, where 30 HM2 or Mk2 have been ordered and possibly eight more may be converted. Possibly.

Now, let’s go even deeper into the helicopter itself. As said above, it is replacing the veteran Sea King helicopter Mk4. The Sea King supposedly is able to carry 28 troops while these Merlins will only carry carry 24 equipped troops. (I’m not so sure the Sea King’s were able to carry that many soldiers. The Agusta-Westland site says the Merlin can carry up to 38 troops but that’s only possibly without gear). There’s a good description on the upgrades of the Merlin HC.3/HC./3A to the Merlin HC.4 in this Naval Technology article. It is pretty well-written so I shan’t summarise it here.

Overall, the Merlin HC.4 plan seems pretty alright, except how the FAA will detail the number of aircraft per flight. The maximum of twelve/12 Merlins for 845 NAS (as you see 846 NAS ultimately is for training and counter-terrorism, with only one flight for troop transport), means the CHF alone can only life a small almost company-sized force from ship to shore or from land to land. This is the stark reality of Future Force 2020.

This post will be updated later.

The Merlin Mk2 Challenge

The Merlin Helicopter Fleet was was identified as one of the two main Naval Helicopter for the Royal Navy, the other being the Lynx Wildcat. The Merlin Mk2 in particular, would be the key anti-submarine warfare (ASW) helicopter for the ASW-centric Royal Navy, an upgraded version of the Mk1. There however, is another role for the Merlin Mk2. It is to be used as a Airborne Early Warning (AEW)/Airborne Surveillance And Control (ASAC) aircraft. This after all is to replace the age-old Sea King Mk7 which have held the ASAC role for a long time since after the Falklands War.

All seems rather simple, but the challenge boils down to numbers. It was longed planned that only only 30 out of 38 Mk1s would be upgraded to the new Mk2 standard. Dividing that between ASW and AEW/ASAC roles, not forgetting there needs to be Merlins for the Type 23s/45s and training/operational conversion units, 30 is a rather low number. Then in May 2014, a report stated that another few Mk1s would be upgraded although the number was not stated. This report further revealed further details:

In the current fleet configuration, 25 Merlin Mk. 2s need to be available at readiness with five in maintenance. Of those 25, 14 will be dedicated to the new Queen Elizabeth-class aircraft carrier (QEC) when that ship puts to sea as part of a task group, with aircraft configured for the ASW role and the airborne early warning mission, equipped with the radar system selected through the Crowsnest program.

That sounds much better for the future Royal Navy, particularly for the carrier-centred Response Force Task Group (RFTG)/COUGAR deployment. Even so, the numbers must be finalised to be more than 30 to make the Mk2 force credible. From the quote, 14 Mk2s will operate off the Queen-Elizabeth Class carrier, though this depends on the mission. This news release, particularly page 71, states that an adequate force would be 4 Merlins for ASW activities, and 4 for AEW/ASAC. It has been reported that only ten Crowsnest (see also this article ) radar sets would be purchased, and not all ten will probably be used. I would wage, as has others, that at the maximum eight (8) sets will be for AEW/ASAC duties, and the remainder for training/OCU.

It sounds nice to have more than 30 Merlin Mk2s but the number must be finalised soon. Stepping back, it’s all about the two carriers. If we have 14 Merlin Mk2s operational on one carrier but the other rotates, we need spare Mk2s to deploy on the next carrier when it relieves the second. Theoretically, there should be 14×2=28 Merlin Mk2s for rotation, though that would mean really stretching the Royal Navy’s budget. But let’s be conservative and have only four Merlin Mk2s (in rotation with the AEW/ASAC Merlins). That means exactly 34 Merlin Mk2s to be brought in service. There’s also the other eleven (11) Merlin Mk2s by the way. We know around five or six (5/6) will be for the small ship flights, 829 Naval Air Squadron (NAS). That leaves the other half for training/OCU or even rotation if the budget is tight and regretably, only 30 Merlin Mk2s will be around from 2015.

Another challenge is which helicopter squadrons will be around when the final numbers of Merlin Mk2s will be fixed. At present:

Merlin Squadrons:
814 NAS
820 NAS (both ASW Merlin Mk1/Mk2s based upon the assault ships/QECs/RFA ships
824 NAS (training/OCU “Parent” unit for the ASW Squadrons)
829 NAS (small ship flights for Type 23/26/35 frigates and destroyers)

Sea King Mk7 AEW/ASAC Squadrons:

849 NAS (training/OCU “Parent” unit for the AEW/ASAC Squadrons)
854 NAS (AEW/ASAC Squadron)
857 NAS (AEW/ASAC Squadrons)

Basing upon 30 Merlin Mk2s, 829 NAS will definitely survive, especially with the future Type 26 frigates with Sonar 2087. 849 NAS will survive until at leasr 2018, operating seven/7 Sea King Mk7. It will probably disband afterwards. Now with 30 Merlin Mk2s and 14 operational on a QEC, that would mean 1) at least one squadron on the QEC. This one squadron will govern all 14 Mk2s, but they be split amongst ASW, AEW/ASAC and Search and Rescue (SAR) duties (you need SAR for an aircraft carrier! Don’t just depend on your escorts). Or 2), two (2) Squadrons governing all 14 Merlin Mk2s on the carrier, meaning one squadron for ASW, one for AEW/ASAC.

As stated, there should (logically) be rotating Merlin Squadrons (one/two back at a Royal Naval Air Station (RNAS) and those on the QEC so that as the carriers rotate, the flight personnel and helicopters do as well. Looking at the picture, since ASW is the bigger component on a QEC (but not more critical), 814 and 820 NAS both should survive post 2015/2020 so that they rotate between each carrier. If option 2) occurs, that would mean 845 and 857 NAS will survive, or one of the NAS will survive but will be double manned (like part of 815 NAS). Not forgetting the 5 or 6 NAS remaining from the 25-14-5/6. Those will either be training/OCU or even a Test and Evaluation Squadron. So either 824 or 849 NAS will survive, but not both.

All this is of course guesswork. But bottom line is that there must be more than 30 Merlin Mk2s in the future and enough NAS squadrons to make both carriers worthwhile.

Update: Well, the Royal Navy has revealed some part of it. 849 NAS, the OCU for the Sea King Mk.7 ASAC/AEW will be the one and only ASAC squadron after 2018, and turn into a front line squadron. It will have three flights of possible six Merlin Mk2s will the Crowsnest technology (logical guess.). Two of the flights are drawn from the two current frontline ASAC/AEW squadrons, 854 and 857 NAS. They will be named “Normandy Flight” and “Palembang Flight” respectively. 857 NAS will disband in 2015 and 854 later. See this link. Sad case for only one ASAC/AEW Squadron but good confirmation.
