GCAP Fighter Jet Engine Passes 100 Subscale Component Tests

Published Jul 23, 12:10 PM UTC

Rolls-Royce, Japan's IHI Corporation, and Italy's Avio Aero have completed over 100 subscale component tests for the engine of the Global Combat Air Programme (GCAP) fighter jet. The milestone, announced on July 20, 2026, reduces technical risk ahead of the more challenging integrated ground demonstrator phase. The engine must provide thrust, electrical power, and heat management for advanced sensors and weapons. The UK Ministry of Defence awarded BAE Systems a £708 million contract extension for sovereign technologies. Canada joined the program as an observer at the Farnborough Airshow. The three nations target 2035 for the aircraft to enter service, with Japan's F-2 retirement schedule adding urgency.
