So in a pre-“Trident Debate” mode let me say…

1) The whole debate is about replacing the ballistic missile submarines (officially the SSBNs). Not the Trident D5 missiles (whose name is incorrectly used to describe the whole system), not the nuclear warheads, which are the ones which cause the devastation. Read this House of Commons research report. Another simple to read document is this one, yet another MOD publication

2) No one and no organisation (including the Campaign for Nuclear Disarmament (CND), the Scottish National Party (SNP), the anti-“Trident” Labour Party members including Jeremy Corbyn) have come up with a sensible idea what to do if the vote falls against the motion. No one has said how to properly scrap the not-even-completed-Successor-class submarines, how to quickly retrain specialised skilled workers, what to do with the Royal Navy submariners destined for these submarines, the support personnel, the civilians who support these personnel, their families. Then what to do with HMND Clyde which is prepared or is preparing to house these submarines.

3) People forget (and in relation to point 1)) that even if the vote doesn’t go in favour, it does not mean the UK’s nuclear weapons are gone. With the vote just about replacing the SSBNs, the missiles (yeah of course they are American-made but British-leased) will still be there. The nuclear warheads will still be there. Again, in relation to point 2, no one has created an idea how to dismantle all of them safely and quickly without thinking about the astronomical cost. At the most, the Yanks (heh) will take back the missiles, AWE will have to prove they can dismantle the warheads (such cost still paid by the British (not just Scottish) taxpayer) and their whole company.

4) A removal of the submarines and then maybe the whole infrastructure (which the vote again is not about) WILL NOT reduce global nuclear weapons or create a spark for nuclear weapons reduction. The response will likely be: US (and France) will increase their warheads or delivery systems to match the loss of the UK’s nuclear deterrent. Or Russia and China may also join the “replace the short fall” race. Or regional, non-Nuclear Proliferation Treaty (NPT) nuclear powers would increase their stockpile.

5) With the lack of any current feasible anti-ballistic missile defence (BMD) system, a total removal of the UK’s nuclear deterrent would be the UK has no option should there be a nuclear threat (however so unlikely) or WMD or non-WMD missiles launched at British territories or interests. Of course, using a nuclear response to a non-nuclear attack has always been ruled out by British governments. However, the total removal of its deterrent means the door will be really open for threats. Can diplomacy and conventional forces subdue the threats?

6) The UK is a puny nuclear deterrent nation. The US has its triad (Bombers, ICBMs and SSBNs with SLBMs and tactical nuclear weapons–eek!), the French has two modes of delivery (SSBNs and via fighters (Rafales) launched by land or via their single aircraft carrier). The Russians have a less updated (maybe) triad which is being modernised. China (PRC) has some sort of triad. And then there are regional nuclear powers as mentioned in point 4. So a removal will mean a removal of the puniest nuclear weapons state.

7) The issue therefore is not about the Successor-class submarines or system of delivery but about reducing what is the real WMD–the warheads. At around 120 operationally available warheads and a stockpile of around 225 warheads, it is argued by pro-“Trident” pundits that is enough or not enough. I say there can be a slow phased reduction but simultaneously, there must be harder or more efforts placed on multilateral non-nuclear proliferation. The UK is right to maintain a minimum deterrent but not correct is being arrogant about it.

8) As the information charts say, this nuclear deterrent has never been set out to deter conventional, state or non-state based threats including terrorism. Yes, each terrorist or non-nuclear attack every day makes it hard to believe that the UK needs a deterrent. I bet the submariners, no some of them, are thinking, what the hell am I doing when London was attacked on 7 July 2005, or the latest Nice attacks. Or what’s happening in Syria. But again, don’t shut down all your electrical goods because you want to save energy. That’s too extreme….

9) Continuous-at-sea-deterrent (CASD) does play another crucial role besides (attempting) to deter nuclear threats from state powers. It helps train submariners, from the chef to the captain, on submarine-based procedures. It’s not your holiday cruise but a military activity where crew members do get their “Dolphins”. Removing their vessels or boats means less ability to train them.

10) Back to point 2. What’s going to replace the SSBNs? There’s no such thing as money immediately going back to the government’s “bank” because you still need to spend it on dismantling the submarines and their infrastructure (as I pointed out), and probably more billions in safely removed the whole system. By then, would you expect government to say, hey, here are savings for the NHS and non-military means? Or military stuff?

From SDSR 2010 to 2015: The “positives”

Well the Conservatives are in full power and they will dominate the decision making for the 2015 Strategic Defence and Security Review (SDSR). People of course will remember the Treasury-led 2010 SDSR which was more of a review to find monetary savings, not to instruct defence plans and to consider security threats. Inasmuch as it wasn’t really a review, the years after until 2015 saw several “positives” for UK defence assets and policies. Below is a (quite incomplete) list of UK defence procurement and initiatives that hae take place, due to the 2010 SDSR as well as the security threats subsequently.

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.
