What it is Filled

An American nine-cylinder air-cooled radial aircraft engine of about 450 horsepower, originating in the J-6 Whirlwind series introduced by Wright Aeronautical in 1929 and later built by Continental; it powered light aircraft and, in variants such as the R-975-E2 and R-975-C1, several Second World War armoured vehicles. Described here at a heritage and technical-history level.

Why it exists Filled

Let an agent describe the R-975 Whirlwind engine by history, variants, general specifications and surviving examples, at a heritage level without operational military detail.
