Differing significantly in design from short-range, high-performance defensive fighters like the Supermarine Spitfire, escort fighters were usually inferior in a dogfight. The perfect escort fighter had long range, a lengthy combat loiter time to protect the bombers, and enough internal fuel to return home.)
