Royal Air Force Cranwell or more simply RAF Cranwell is a Royal Air Force station in Lincolnshire, England, just west of the village of Cranwell, and approximately 4 miles (6.4 km) east-northeast from Sleaford. Among other functions, it is home to the Royal Air Force Officer Training Academy (RAFOTA), which trains the RAF's new officers and aircrew. The motto, Altium Altrix, meaning "Nurture the highest" appears above the main doors of the Officers Mess. Since January 2025, RAF Cranwell has been commanded by Wing Commander Matthew "Chocka" Thornton.
