The S.5 followed the failed S.4 with much more metal in its structure, an RAF 30 wing section, and a 900-horsepower Napier Lion. Although it was shorter and had a smaller span, it reached about 319 mph and won the competition. That was an increase of approximately 80 mph in only two years. The smaller racer measured the rapid changes in structure and aerodynamics driven by Schneider Trophy competition.

The S.5 paired metal construction with an 80 mph speed jump
See how greater use of metal, an RAF 30 wing section, and a 900 hp Napier Lion accompanied the smaller S.5's victory at roughly 319 mph.
