Question

What changes if a 3,500-horsepower Napier Sabre VII is available in 1941?

Short answer

Britain wins an early engine-horsepower advantage, with major effects on bombers, fighters, and possible US interest.

Notes

A reliable 3,500-horsepower Napier Sabre VII in 1941 would put British aircraft engines well ahead of German, Italian, and Japanese competitors. The engine could transform Lancaster-class bombers and provoke competition between Fleet Air Arm and Royal Air Force fighter programs. The United States might consider it for the B-29 or pursue an even more powerful domestic alternative. The main effect is an early British lead in the aircraft-engine horsepower race.
