WWI Engine research. Developed the engine that would eventually be used in the first successful tank design, the British Mark V. A total of over 8,000 of Ricardo's tank engines were put into military service, making it the first British-designed engine to be produced in large numbers. The Mark IX tank and the British version of the Mark VIII (tank) also used a Ricardo engine.
