RAF Mildenhall History: Project Ruby
This month marked the first major involvement by the USAAF with RAF Mildenhall in 1945. Two B-17 Flying Fortresses arrived at the station for bomb trials. They were stripped of their armament and modified to carry a rocket assisted 4,500 lb bomb, or a 2,000-pound bomb with a special penetration head under each wing. A third B-17 arrived shortly after the first two. These were the Project Ruby deep penetration trials. (Photo courtesy of the 100th Air Refueling Wing Historian)
