BELFAST — The UK says a sixth-generation fighter contract is to be signed in a matter of weeks, in line with bilateral talks held over the weekend between Prime Minister Keir Starmer and Japanese premier Sanae Takaichi.

The flagship project of the Global Combat Air Programme (GCAP) between Italy, Japan and the UK has faced uncertainty amid infighting between the British Ministry of Defence and the Treasury (UK budget office), which has, in collaboration with Starmer, struggled to address a budget shortfall. The inking of the fighter contract could help relieve GCAP partner concerns however.

“During the meeting [in London], the Prime Ministers are expected to confirm their shared commitment to the Global Combat Air Programme, and discuss the launch of the next phase of the international programme, including through the international contract that will be signed by the end of the month,” the UK Prime Minister’s Office said in a Saturday statement.

Italy, Japan and the UK, are committed to the future fighter effort, with a timeframe of 2035 marked as the sixth-generation type’s entry to service. However, Tokyo reportedly raised eyebrows at the UK holding up funding for an existing £686 million ($905 million) design and development contract.
