Development of the Hawker Typhoon began in 1936 when Sydney Camm, designer of the Hurricane, started working on its successor. Camm proposed two designs: one powered by Napier Sabre engine and another (Type R) powered by Rolls-Royce Vulture engine; both delivered more than \[2\],000 horsepower.
These designs were submitted to Britain's Air Ministry which issued Specification F\.18/37 calling for an aircraft capable of flying over \[400\] miles per hour at \[15\],000 feet with an impressive service ceiling up to \[35\],000 feet armed heavily with machine guns among other specifications needed then placed orders totaling \[500\] units each design named Tornado & Typhoons respectively by July \[1939\].
The first prototype took flight on February \[24th\], \[1940\], powered by Napier Sabre engine despite developmental delays caused initial testing setbacks including mid-air structural failure May same year yet test pilot Philip Lucas managed landing earning him George Medal recognition thereafter production prioritized proven models like Supermarine Spitfire & Hurricanes under Lord Beaverbrook's directive until second prototype armed Hispano cannons flew May third finalizing orders exceeding thousand fighters from Hawkers alone while Avro handled Tornado developments separately ensuring focus remained building crucial Hurricanes needed
