The Rolls-Royce Hawk
was a British aero engine
designed by Rolls-Royce
in 1915. Derived from one bank of six cylinders of the Rolls-Royce Eagle
, it produced 75 horsepower
at 1,370 rpm. Power was progressively increased to 91 hp by February 1916, and 105 hp by October 1918.
After Rolls-Royce made the prototypes, the Hawk was manufactured under licence by Brazil Straker in Bristol between 1915 and 1918. During this period 204 engines were built, and the Hawk earned a reputation for high reliability.
Many engines of this type were used to power the SSZ class coastal patrol airships of which 76 were built.
