The RAF is set to acquire 12 F-35A aircraft, which are capable of carrying nuclear weapons, but there are concerns over how they would be integrated without compromising the jet’s stealth capability, Air Chief Marshal Sir Rich Knighton has warned.The UK plans to acquire an additional F-35s – taking the total up to 74 – and the 12 F-35As will give the RAF a nuclear capability for the first time since the 1990s.However, in a meeting of the Public Accounts Committee, ACM Sir Rich told MPs he was worried about “the integration of a standoff weapon onto that platform to ensure that we’re able to maximise the value of the stealth capability”.
