P.1154 naval fighter versus the F-4 Phantom

The P.1154 would not match the Phantom on the Royal Navy's preferred terms, but it could create a distinctive and politically attractive British carrier capability.

Question

How would the naval P.1154 compare with the F-4 Phantom?

Short answer

It would not equal the Phantom in the Navy's preferred two-seat interceptor role, but it could offer a valuable uniquely British V/STOL capability.

Notes

The panel expects the aircraft to fall short of the Phantom as a direct like-for-like fleet fighter, particularly where the Navy wanted a two-seat, radar-equipped solution. Its vertical or short takeoff potential nevertheless gives the government a reason to force adoption and could push the Royal Navy toward an unusual but capable operating model. A successful supersonic V/STOL fighter would also interest the US Marine Corps and could change later British carrier plans and Soviet responses. Weight distribution probably keeps the operational aircraft single-seat even if a two-seat trainer exists. The comparison therefore turns on mission systems, crew requirements, and fleet architecture as much as speed or manoeuvrability.
