Rolls-Royce Hawk

The Rolls-Royce Hawk was an aero engine built by Rolls-Royce, similar to one bank of six cylinders from the Rolls-Royce Eagle.

It was produced between 1914 and 1918, during which 204 were built at Brazil Straker and one by Rolls-Royce. Many were used to power SSZ blimps; coastal patrol airships.

The British Rolls Royce Hawk engine was used in the British-Built SS "Zero" (Submarine Scout, Zero) airship of which 76 were built.
