what is it?
Replica was a design study for an envisioned military aircraft with stealth capabilities, developed by British defence manufacturer BAE Systems. It was ultimately not pursued as the British government chose to proceed with involvement in the American Joint Strike Fighter programme instead, which ultimately led to the Lockheed Martin F-35 Lightning II. The design study was associated with the Royal Air Force's (RAF) Future Offensive Air System (FOAS) initiative, which was ultimately discontinued. A key attribute of the conceptualised aircraft was the integration of low observability features, which were intended to achieve a balance between reduced detectability and overall affordability.
