A modified F-15E Strike Eagle, assigned to the 494th Fighter Squadron, launched on an operational training mission with the bomb release unit-61 attached to the center pylon at Royal Air Force Lakenheath, England, Monday. The aircraft was one of four to participate in the first training mission with the new technology. The BRU-61 carries the newest small-diameter bomb, the guided bomb unit-39, into battle when the unit deploys in September. (U.S. Air Force photo/Airman 1st Class Michael Hess)
