Group Captain Maurice Vivian de Touffreville Fox-Strangways, 9th Earl of Ilchester (1 April 1920 – 2 July 2006), styled Lord Stavordale between 1964 and 1970, was a British engineer.

Fox-Strangways was born in Port Tawfiq in Egypt while his father was serving in the British foreign consular service.

He was educated at the now-defunct Kingsbridge Grammar School, and joined the Royal Air Force (RAF) as an apprentice in January 1936, aged 15.

Fox-Strangeways was selected for commissioning and he attended the Royal Air Force Technical College at RAF Henlow in 1953.

By the mid-1950s he was a Squadron Leader and became involved with the development of nuclear weapons at the Directorate of Air Armament Engineering.

As a wing commander, he served at RAF Biggin Hill, involved in recruitment of officers and aircrew.

Finally, promoted to group captain, he was the assistant director of air weapons development at the Ministry of Technology, and was involved with the UK's Polaris ballistic missile programme.
