Behold, the most ridiculous MOD decision since they removed cats and traps from the QE design.
To be clear, I'm in favour of bolstering our nuclear deterrence. However, we already provide nuclear ICBM capability to NATO - one of only three countries to do so.
Quite why NATO (or let's be realistic, the USA) needs a 7th country capable of employing the same ancient "dumb" nuclear bomb is completely lost on me. Our "NATO first" approach recognises that Belgium, Germany, Italy, the Netherlands, and Turkey already fulfil this role. The UK's additional 12 airframes will contribute nil towards NATO's strategy, while providing the UK nil in terms of sovereign nuclear capability.
By the time F-35A becomes a reality for the UK, Tempest will be maturing, which is all but certain to be a more suitable air frame for this job with greater range and payload. It's also an obvious requirement that these weapons need to be delivered by way of stand-off cruise missile - not a ww2 style dumb bomb which will require F-35A to survive overhead, at high altitude, in a hotly contested environment - something that is questionable today, let alone when we finally receive them. Then there's the question of refuelling them (our current tanker fleet can't do this for F-35A), and weapons integration (F-35B STILL can't employ our world-beating meteor missile, and won't now until "early 2030's").
A new American airframe, to drop an ancient American bomb, on a new American friend, with explicit American permission. It's nothing short of Trump fluffing.
God forbid we support our own brand new 6th gen fighter program.
Leave it to the French to provide a nuclear deterrence that everyone, even an increasingly adversarial USA, is obliged to respect.
