The UK is about to commit to the F-35 fighter project, a US-led effort to produce 3,000 aircraft which is set to cost more than £600bn globally.

The initial UK order for 14 F-35Bs will, with support costs added, cost about £2.5bn, Newsnight has learned.

Defence Secretary Philip Hammond said the F-35B was an expensive plane, but one with an "incredible capability".

But critics have questioned Ministry of Defence suggestions that the jets will be combat capable by 2018.
