The Armstrong Siddeley Cougar was an aero engine developed by Armstrong Siddeley in 1945. The design was a departure from earlier Armstrong Siddeley engines in many ways, it was the company's only nine-cylinder radial design. Although the engine was tested it did not find an aircraft application and was not produced.
