Operations.  The 509 Composite Group, the first Army Air Forces group to be organized, equipped, and trained for atomic warfare, moved to Tinian by Jun 1945 and flew practice missions through Jul.  On 6 Aug 1945 a B-29 named the “Enola Gay,” piloted by the group commander, Col Paul W. Tibbets Jr., dropped an atomic bomb on Hiroshima, Japan.  Three days later “Bockscar” piloted by Maj Charles W. Sweeney, dropped a similar bomb on Nagasaki.  These two bombs, the first atomic weapons ever employed, contributed immensely to the war’s end.  The group returned to the United States, Oct-Nov 1945.  In Mar 1946, the group provided the nucleus for the Strategic Air Command’s atomic striking force.  Later in 1946, participated in atomic tests (Operation CROSSROADS) in the Marshall Islands.   After CROSSROADS, except for two periods when the group was not operational (17 Nov 1947-14 Sep 1948 and 10 Feb 1951-16 Jun 1952), trained in long-range bombardment and air-to-air refueling missions.  The group inactivated on 16 Jun 1952.   Since 1993, supported, maintained and operated aircraft fleet that enabled the 509 Bomb Wing to fulfill its mission of conducting conventional or nuclear operations.  Equipped with B-2s.  Since 1993, with like-numbered wing to which it was assigned, furnished USAF’s only source of stealth heavy bomber capability.  In 1999, flew nonstop bombing missions from Whiteman AFB, MO to Serbia during Operation Allied Force.  At the beginning of Operation Enduring Freedom, in October 2001, six of the group’s B-2s flew the longest bombing missions in history, from Whitman to Afghanistan after flying across the Pacific and Indian Oceans.  Each of those flights took more than 40 hours.  After landing at Diego Garcia briefly, the six B-2s returned to Whiteman, after 30 more hours of flying, but with different crews.  The group also took part in Operation Iraqi Freedom in 2003, flying non-stop flights from Missouri to targets in Iraq.  Maintained combat-ready resources to conduct conventional or nuclear operations. In Feb 2005 started continuous deployments to Andersen AFB, Guam to provide bomber presence in the Asia-Pacific region.  Group B-2s also flew missions during Operation Odyssey Dawn in 2011.
