The 509th Operations Group is the flying component of the 509th Bomb Wing, assigned to Whiteman Air Force Base, Mo.
It is equipped with all 20 of the USAF's B-2 Spirit stealth bombers, and also employs a robust fleet of T-38 Talon trainer aircraft.
The 509th OG traces its history to the World War II-era 509th Composite Group, which conducted the atomic bombings of Hiroshima and Nagasaki, Japan, in August 1945.
In 1993, the unit was reactivated as the 509 OG, as part of the objective wing organization implementation of the 509th Bomb Wing.
