The NATO nuclear mission raises questions about force size and funding

Why buy into NATO's dual-capable aircraft mission when Britain already has a nuclear deterrent?

It may add another deterrent option and allow funding through the nuclear budget, but the small order and distant delivery date cast doubt on its practical value.

The decision could be a first step toward an additional deterrent leg, but twelve aircraft are too few to make that step convincing. A possible accounting motive is that assigning a nuclear mission lets the F-35A purchase sit within the ring-fenced nuclear budget. The aircraft are not due to arrive until the 2030s, leaving several opportunities for a later government to alter the order. The plan's nuclear symbolism and accounting logic therefore run ahead of a fully developed operational force.
