GCAP sixth‑generation fighter program gains momentum in Europe and Asia

The United Kingdom, Japan and Italy are jointly developing a sixth‑generation combat aircraft under the Global Combat Air Programme (GCAP). The partnership, formalised in July 2026 with a £4.6 billion agreement, is led by the Edgewing consortium – comprising Italy’s Leonardo, Britain’s BAE Systems and Japan’s Aircraft Industrial Enhancement Company – and aims to field the aircraft, known as Tempest, by 2035. The design follows a “system‑of‑systems” approach that integrates autonomous drones and real‑time data hubs. A prototype is expected to fly by the end of 2027, with the programme’s development phase running through 2030.

Singapore has expressed interest in joining GCAP as an observer, evaluating how a sixth‑generation fighter could fit alongside its existing fleet of F‑15SG, F‑16 and P‑8A aircraft. While negotiations remain exploratory, the Singapore Air Force’s long‑term planning reflects a desire to integrate fifth‑, sixth‑generation platforms and unmanned systems within a multi‑layered combat architecture.

Leonardo’s CEO Lorenzo Mariani has indicated that the partner nations are discussing an accelerated entry‑into‑service date, potentially moving the operational debut from 2035 to as early as 2033. The acceleration would involve revising initial requirements and streamlining the development process, while still maintaining a phased capability build‑up over the aircraft’s lifecycle.
