The Whirlwind was designed by engineers Lawrance, Jones and Heron under supervision of P. B. Taylor. The aim was to obtain a reliable, medium power aircraft engine. The Whirlwind engine proved exceptionally successful. In 1927 Charles Lindbergh made a non-stop flight across the Atlantic from New York to Paris in Ryan NYP “The Spirit of St. Louis”, powered by J-5C Whirlwind engine. In the 30’s these engines were licence-built in Poland by Polish Skoda and Avia companies. 5-, 7- and 9-cylinder Whirlwinds powered training, observation, executive aircraft and airships. Whirlwinds built under licence by Continental Motors were used in tanks (M3 Lee, M4 Sherman, Ram) and self-propelled guns.
