Rolls Royce Griffon Engine

This page has hierarchy - Parent page: Engines & Weapons

The Rolls-Royce Griffon is a British 37-litre (2,240 cu in) capacity, 60-degree V-12, liquid-cooled aero engine having a similar general configuration to its smaller capacity stablemate, the Merlin. Design work on the Griffon started in 1933, but development was temporarily put on hold to concentrate efforts on the smaller Merlin and the engine did not go into production until the early 1940s.

The Griffon was the last in the line of V12 aero engines to be produced by Rolls-Royce Limited with production ceasing in 1955. Griffon engines remain in Royal Air Force service today with the Battle of Britain Memorial Flight and also power the last remaining airworthy Avro Shackleton.
