Answering a question in the House of Commons Minister of State at the Ministry of Defence (MoD), Jeremy Quin, said that, while the international Block 4 (full combat) upgrade has been costed into the UK’s procurement programme, the precise numbers of already-delivered jets to go through the retrofit process have not yet been decided.
“The F-35 Block 4 upgrade has been included in the UK F-35 programme budget since its inception. Decisions on the number of aircraft to be upgraded will be made on the basis of military capability requirements. The costs of the Block 4 upgrade are managed through the F-35 Joint Programme Office and, as one partner in the multinational F-35 programme, the UK is not in a position to share detailed cost information,” the minister said.

Also worth noting that, aside from the Block 4 update, the UK has already committed itself to fitting its aircraft with the new Raytheon Distributed Aperture System. No costing for this given, but will likely take a large chunk out of any wider retrofit budget.— Gareth Jennings (@GarethJennings3) June 24, 2020
