History
The unit was established in early 1944 at Dalhart Army Air Field, Texas, being formed as a B-29 Superfortress Very Heavy bombardment Group. Thu unit was initially formed with four bomb squadrons (393d, 398th, 421st, and 507th ), being a mixture of both newly-constituted and reassigned units. The 398th was formerly a III Bomber Command B-25 Mitchell medium bomber Operational Training Unit in the southeastern United states, being formed in 1942. It later became a B-26 Marauder Replacement Training Unit until being inactivated in October 1943.
Due to a shortage of B-29s, the group was initially equipped with former II Bomber Command B-17 Flying Fortresses previously used for training heavy bomber replacement personnel. The unit was then reassigned for advanced training and received B-29s at Fairmont Army Airfield, Nebraska during the late spring and summer of 1944.
In May shortages in aircraft and equipment led to the 507th Bomb Squadron being inactivated, with its personnel being consolidated into other group squadrons (the 507th would be reactivated a month later as part of the 333d Bombardment Group). In November, the 393d Bombardment Squadron was reassigned to the to 509th Composite Group at Wendover Field, Utah, leaving the 504th to be a two squadron group. The 393d became the 509th's only operational B-29 squadron. The 393d would eventually become the only military unit in history to engage in Nuclear warfare, dropping Atomic Bombs on Hiroshima and Nagasaki, Japan, in August 1945.
As a two squadron group, the 504th was deployed to Pacific Theater of Operations (PTO) in late 1944, being assigned to the XXI Bomber Command 313th Bombardment Wing in the Northern Mariana Islands; being stationed at North Field, Tinian. The group began combat operations from Tinian in January 1945 with attacks on Japanese airfields and other installations on Maug and Iwo Jima and in the Truk Islands. Flew its first mission against the Japanese home islands early in February 1945 when the group bombed the industrial area of Kobe. Continued to attack strategic targets in Japan, operating in daylight and at high altitude to bomb such objectives as aircraft factories, chemical plants, harbors, and arsenals. Switched to night incendiary raids attacking major Japanese cities in the spring of 1945, causing massive destruction of urbanized areas.
Received a Distinguished Unit Citation (DUC) for striking the industrial center at Yokohama late in May 1945. Began incendiary raids in March 1945, flying at night and at low altitude to strike area targets in Japan. Started mining operations against enemy shipping late in Mar, receiving a 2d DUC for mining Korean shipping lanes, the Shimonoseki Strait, and harbors of the Inland Sea, July–August 1945. In April and May 1945 the group hit airfields from which the Japanese launched kamikaze planes against the invasion force during the assault on Okinawa. During mid June 1945 the 680th Bomb Squadron was attached to the 504th bomb group to bring the group up to full strength with 3 squadrons. The group continued strategic bombing raids and incendiary attacks until the Japanese Capitulation in August 1945.
After V-J Day, the 504th dropped supplies to Allied prisoners, participated in show-of-force missions, and flew over Japan to evaluate bombardment damage. In the fall of 1945, the group largely demobilized as part of the "Sunset Project", with some aircraft being sent reclamation on Tinian; others being returned to the United States for storage at aircraft depots in the southwest. By Christmas, the group fleet was reduced to 30 or less planes Many of the remaining veterans signed for "any conditions of travel" to get home, arriving three weeks later in Oakland, California, where troop trains scattered them for points of discharge close to their homes.
The unit was largely a paper organization when it was reassigned to Clark Field in the Philippines in March 1946, and assigned to Thirteenth Air Force. At Clark its remaining aircraft and personnel were consolidated into other units, and it was inactivated in June.

Famous quotes containing the word history:
“What is most interesting and valuable in it, however, is not the materials for the history of Pontiac, or Braddock, or the Northwest, which it furnishes; not the annals of the country, but the natural facts, or perennials, which are ever without date. When out of history the truth shall be extracted, it will have shed its dates like withered leaves.”
—Henry David Thoreau (1817–1862)
“No cause is left but the most ancient of all, the one, in fact, that from the beginning of our history has determined the very existence of politics, the cause of freedom versus tyranny.”
—Hannah Arendt (1906–1975)
“There has never been in history another such culture as the Western civilization M a culture which has practiced the belief that the physical and social environment of man is subject to rational manipulation and that history is subject to the will and action of man; whereas central to the traditional cultures of the rivals of Western civilization, those of Africa and Asia, is a belief that it is environment that dominates man.”
—Ishmael Reed (b. 1938)
