Strategic Air Command in the United Kingdom
Between 1948 and 1992, personnel and aircraft of the United States Air Force (USAF) Strategic Air Command (SAC) were routinely deployed to bases in England. An informal agreement to base SAC bombers in the UK was reached between US General Carl Spaatz, and Marshal of the Royal Air Force (RAF) Lord Tedder, in July 1946.
