Tempest

Also known as
  • BAE Systems Tempest
  • Tempest FCAS
  • Future Combat Air System
  • FCAS
  • Global Combat Air Programme
  • GCAP

Tempest is the UK name for the crewed fighter at the centre of the Global Combat Air Programme, a UK-Italy-Japan effort to develop a next-generation stealth combat aircraft with digital engineering, advanced sensing, and networked future-air-system roles. The programme is not fielded in combat, so this draft records programme identity and development context without conflict-use claims.

Programme Status

Tempest is best read as a development programme rather than a fielded aircraft. Official programme sources describe a crewed stealth fighter planned for GCAP, supported by uncrewed platforms, next-generation weapons, networks, data sharing, and training rather than a single aircraft-only replacement.

Current phase

Advanced concept, assessment, and detailed design work under an 18-month Edgewing contract announced on 2026-07-03.

Industrial structure

Edgewing leads GCAP aircraft design and development, drawing on BAE Systems, Leonardo, and Mitsubishi Heavy Industries as national lead systems integrators.

Conflict-use limit

No direct source found for operational combat use; the aircraft remains in development with a 2035 target stated by programme sources.
