True a 155mm solution would offer synergy with army ammunition supplies. But no navy operates a split charge 155mm solution at the moment, many navies do operate 5inch guns and it is a proven solution hence why it does make sense for the export market.
Considering the MK8 Mod1 is no longer in production and current turrets would be overhauled for RN Type 26 they needed a realistic option for export sales. So I’m not surprised about Babcocks agreement with Finmeccanica, the OTO127mm is a fine gun and makes the Type 26 more attractive.
At the moment I still see Merlin as the MASC solution with Cerberus and Searchwater 2000AEW.
The only way I see Hawkeye being operated by the UK is if we do some form of joint squadron with the French by co-financing at least a couple more Hawkeyes and then operating them as part of a common pool with the French keeping all maintenance and support in France where it already is. The French operate three Hawkeye as it stands and would like a fourth, that would give five Hawkeye which is enough to service Charles De Gaulle and whatever CVF is available at the time.
The Key questions would be:
a) Does purchasing a couple of Hawkeye and operating them with France cost less then refiting seven or eight Merlin as a MASC type?
b) Could they sort out the politics of it and operational practicalities between the FAA and Aeronavale?
One thing of note is neither the Royal Navy or Carrier Alliance Websites have updated yet, still all the pictures and information about the STOVL design nothing nefarious in that but amusing nevertheless:

Well Diesels might well be adequate to provide the power requirements of EMALS/EMCAT then again a smaller Gas Turbine can be compact.
I have no doubt that if they fit EMALS or EMCAT more diesels or Gas Turbines will be required to run it.
There is no chance that MK13 steam catapults will be fitted because the RN doesn’t know how to look after steam plant anymore and doesn’t want to relearn.
Also weight is important, CVF performance is marginal as it is for CATOBAR operations so the top weight of the plant required for catapult launch and landing will be critical!
I’m aware of the AAG program which as of yet isn’t in service, but I wasn’t refering to that.
I was making the comparison with current in service US MK-7 arrester gear engines that are less advanced then the British DAX-II. MK-7 isn’t much changed now then thirty to forty years ago when DAX-II was fitted to the old Ark Royal.
I should of made that more clear.
I would also add to that the time taken for extra contractors to be brought onboard, UK and American.
The Mujahadeen were trained to use the Stinger – as part of the process of distributing the MIM-92, the Americans initiated a training scheme which took into account the typical low level of literacy among the Muj.
I’m afraid that this is also a myth perpetuated about Mujahideen use of the FIM-92 Stinger during the war against Russia.
The Americans supplied the FIM-92 to Pakistan who then supplied it to the Mujahadeen. The training was provided by the ISI/Pakistan army who had been trained by the US.
Once trained in Pakistan Mujahideen fighters were supplied limited numbers of Gripstocks depending on how trustworthy the ISI regarded the particular Afghan factions. When it came to missiles themselves the ISI would only supply a couple to a faction at one time and then only give replacements when they brought back the empty launch tubes on a like for like basis.
This was to ensure there were not lots of missiles just washing around in Afghanistan and also ensure that the fighters did actually use them, despite that some accidently passed over the border into China and Iran who studied them for their own missile programs.
Arguably the most effective weapon supplied to the Mujahideen was the 107mm rocket, the Chinese even put the single tubed variant back into production to sell to Pakistan using American money who then passed them onto the fighters.
hmmm my guess the vague statement from the press office is more down to the fact that BAE Systems, Thales and Babcock are in frantic meetings thrashing out the change in build strategy. As it is they have to put the brakes on fairly quick as Cammell Laird are in effect building incorrect flight deck modules now. They will have to stop that to allow redesign time, remember the CATOBAR configuration was only a proposal. My hope they will be able to streamline this work using whatever design proposals Thales put together for PA2 and the French Navy but nevertheless it throws a massive spanner in the works stopping build to allow redesign time plus reschedule a carefully planned build strategy! Proposals will also now need to be put together for the CATOBAR deck equipment, everything from the arrester gear and catapult through to extra power generation plant and landing sights (more then likely the American IFLOLS). Any American equipment will also need an export licence and I presume FMS clearance which is a formality but again adds time.
Agree, though not because of energy recovery (not sure if that’s actually planned, since storing that much electrical energy and particularly charging the “reservoir” so quickly, will be a challenge) but because of maintenance requirements. Is DAX-II a conventional hydraulic ram system or the famous water spray based one? If it’s the latter they may well have a shot, since AAG does have water brakes as well and water spray appears to offer many of the same benefits in reducing deceleration loads on the airframe.
This is all I know about DAX-II taken from Beedles site, I would love to know more:
Landing aircraft would engage the wires of a new type of direct action water-spray arresting gear built by MacTaggart Scott, these could engage aircraft at higher speed than possible with contemporary equipment. A unique feature of the device was its ability to halt all aircraft in the same run-out distance – regardless of weight and landing speed – thus simplifying flight deck operations. The new arresting gear was about one-third the weight and half the cost of the currently standard Mk.13 arrester gear. A single DAX II (sometimes referred to as DA-2) wire was experimentally fitted to HMS Eagle during 1966, and a full set of four to HMS Ark Royal during her 1967-70 major refit (a refit instigated after the cancellation of CVA-01).
The diagram below represents the concept:

That MacTaggart Scott is still around helps significantly going British in this respect also whilst they haven’t made a new set of Arrester gear engines in many years I presume they still provided technical support for the Clemenceau class and other carriers when Ark Royal (the CATOBAR one) retired through the 80’s, 90’s and maybe even now in respect of Sao Paulo’s recent refit. So they have been able to keep their hand in when it comes to arrester gear systems.
DAX-II is waterspray. When it was developed it was meant to be cheaper, lighter, smaller and lighter then the equivalent hydraulic system. It is also meant to be easier on the landing aircraft and run them out to the same place on deck.
Whilst going for the US arrester gear engine is low risk I think MacTaggart Scott still have a fairly low risk system. Remember technology wise the US arrester gear engine isn’t that much changed from those used fifty years ago whilst in all respects DAX-II is a newer concept. Also arrester gear engines made in the US and the UK are not mass produced but rather bespoke effectively hand made systems. MacTaggart Scott despite not making an arrester gear engine in decades has better chance at building one with minimal risk then Converteam does with its EM catapult which is still in prototype stage.
The main advantage that the US built systems have over the UK is the facilaties in the US. If the UK decides on its own arrester gear engines and catapult they will have to be built and tested on land here. Using US facilaties piggy backs of USN/DOD spending.
Actually on that note I am also tempted to email MacTaggart Scott about if they intend to bid DAX-II for the CVF build.
I would think the US would be very happy with an F35C sell to the UK as it equates to potentially far more money being spent in America.
Unless MacTaggart Scott and Converteam can put forward a good deal with a DAX-II variant and UK EMALS then we will have to buy that off America along with the engineering help to design them in. Also the UK will now have to buy itself into American training for personel.
Interesting Buitreaux whilst I have always asumed that Brazil plans to build its own carrier in the future I didn’t realise there were any plans for a three carrier build with one going to Argentina.
Of course Brazillian shipyards are expanding and the current plans for technology transfer in respect of the Frigate replacement program so moving onto a carrier is a logical next step. Is there any documentation or reports about these plans? I would be interested in viewing them.
This also has significant implications for the UK’s CVF build, if it can be shown that the South Atlantic threat environment will increase for the UK with a new Argentine carrier it gives more ammunition to the Royal Navy about retaining both carriers.
In respect of the frigate replacement program in Brazil I think the UK should offer as part of the offset if the UK got the contract with Type 26 the building of at least a couple refueling tanker hulls, it would benefit the Royal Navy at a far reduced cost and help with technology transfer in respect of large hull vessels. Finally throw in the Type 22 Batch three as a sweetner and everybody is happy!
