The judgement call

Account-gated at launch

GCAP represents a significant international collaboration to develop future combat air capabilities. - The programme aims to deliver a fighter jet for 2035, replacing existing fleets. - Emphasis on deep-strike capability, stealth, long range, and heavy weapons load.

Key engineering challenges

Developing a highly advanced, interoperable, and connected sixth-generation fighter jet. - Integrating cutting-edge technologies such as stealth, AI, and drone teaming. - Managing a complex multinational development and production programme. - Ensuring the aircraft meets the diverse operational requirements of three nations.
