GCAP Sixth-Generation Fighter Contract to Be Signed This Month as UK, Italy and Japan Advance Program

The UK government has confirmed that the full international contract for the Global Combat Air Programme (GCAP) sixth-generation fighter jet will be signed before the end of June 2026. According to Breaking Defense and Jane’s reporting on June 16, the deal will transition the program from a £686 million bridge contract into a unified trinational legal framework covering the UK, Italy, and Japan.

Contract Crossing the Finish Line

GCAP’s joint vehicle — Edgewing, formed by BAE Systems (UK), Leonardo (Italy), and JAIEC (Japan) — is moving to finalize the full program contract after UK ministers confirmed negotiations were in their final stages. Army Recognition previously reported a combined bridge contract value of $850 million for the three nations. The full contract will encompass multi-decade development, manufacturing, and sustainment commitments expected to run into tens of billions of pounds sterling.

What GCAP Brings

GCAP is a sixth-generation combat aircraft targeting a 2035 service entry. Core capabilities include manned-unmanned teaming (MUM-T), advanced sensor fusion, AI-assisted combat management, and operations in heavily contested airspace. The aircraft is designed to replace the Typhoon in UK and Italian service and the F-2 in Japan — representing the most significant air combat procurement in each nation’s recent history.

The program’s industrial architecture ensures work share is distributed across the three nations. Beyond the prime contractors, the GCAP supply chain will draw in specialists across radar, electronic warfare, and weapons integration — with names like MBDA, Safran, and Leonardo DRS already prominently positioned.

Strategic Context

GCAP’s contract signature arrives at Eurosatory 2026 — a show centered on the theme of “Industrial Warfare” — underscoring how deeply the defense industrial base is reshaping itself for high-intensity peer conflict. France, meanwhile, is pursuing its own sixth-generation fighter under the FCAS program with Germany and Spain, ensuring that Europe’s premium air power tier remains a competitive, multinational affair.
