What happened

The UK is building a next generation fighter jet in collaboration with Italy and Japan.

Common ground

The GCAP aircraft, which will be known in Britain as Tempest, should enter service by 2035.

Claim 7: “On July 3 2026, the UK, Italy and Japan signed a £4.6 billion deal to move the project into its next design phase.”

DISPUTED

The claim states the deal was signed on July 3, 2026. However, the provided evidence for Edgewing mentions it was launched in June 2025. More importantly, July 3, 2026, is a future date relative to the current real-time context of the evidence provided (which discusses 2025 events). The specific date and year provided in the claim are not supported and are chronologically inconsistent with the 'launched in June 2025' evidence.
