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.
The 13th Bomb Squadron provides combat training for the B-2 Spirit aircraft, preparing aircrews and squadron personnel to support of Joint Chiefs of Staff nuclear and conventional taskings.
The unit trains for high- and low-altitude, day or night missions to ensure maximum combat readiness, while building a combat force capable of projecting B-2 global firepower at a moment's notice, anytime, anywhere.
Constituted on June 14, 1917, the 13th Bomb Squadron is one of the oldest units in the United States Air Force, and was deployed to Europe during World War I.
The unit has been engaged in almost every major conflict - World War I, World War II, Korean War, Vietnam War, Global War on Terrorism - in which the United States Air Force or its predecessors has been involved.
The 509th Operation Support Squadron Hawks make the wing ready to fight. The OSS manages the airfield and all airfield operations for the wing, to include the tower, radar approach control, base operations and weather support.
OSS also functions as a wing intelligence provider, supporting the conventional and nuclear mission of the B-2 and integrating with theater commanders to assist in war planning.
The 509th OSS is the wing's weapons employment experts, with the most experienced and knowledgable B-2 instructor pilots in the wing, supporting mission planning for wartime and peacetime missions.
They manage the "stealth" of the B-2 fleet with a survivability flight, and combine all efforts to put the tip on the spear of national defense.
