The squadron was first activated in 1942. After training in the United States as a medium bomber unit, it deployed to the Southwest Pacific Theater, where it engaged in combat, advancing from Australia, through New Guinea and the Philippines, earning two Distinguished Unit Citations and a Philippine Presidential Unit Citation for its combat actions. Following V-J Day, the squadron remained on Okinawa until December 1945, when it returned to the United States for inactivation. The squadron was activated again in 1957 as a tactical bomber unit.
History
editWorld War II
editThe squadron was first organized at Columbia Army Air Base, South Carolina in September 1942 as one of the four original squadrons of the 345th Bombardment Group.[2][4] However, it was not sufficiently manned to begin flight training until December.[5] The squadron trained with North American B-25 Mitchell medium bombers until April 1943, when it departed for the Southwest Pacific Theater.[2][4] The squadron had originally been slated for deployment to the European Theater of Operations, but was diverted to the Pacific at the request of General George C. Kenney following the successful use of medium bombers in the Battle of the Bismarck Sea.[5]
Staging through Australia, the unit reached its combat station near Port Moresby, New Guinea in early June 1943.[2] In theater, its B-25s were modified, including the installation of additional fixed machine guns to equip it for strafing missions.[5] It flew its first combat mission on 30 June. The squadron operated from New Guinea until July 1944, with missions that included bombing and strafing Japanese installations in New Guinea and the Bismarck Archipelago. The squadron attacked enemy shipping in sealanes within range of its Mitchells. It flew air support missions for ground units in the Admiralty Islands, including airdropping supplies to units. It also flew courier and aerial reconnaissance missions.[4]
On 2 November 1943, the squadron flew a series of attacks on flak positions, coastal defenses and barracks at Rabaul, a major Japanese naval base in New Britain. These attacks earned the squadron its first Distinguished Unit Citation (DUC). In July 1944, the 501st moved to Biak Island in the Netherlands East Indies. From its new base, it attacked airfields and shipping in the Philippines and Celebes. It continued moving forward with Douglas MacArthur's forces, occupying a base in the Philippines in November 1944, which enabled it to strike military targets throughout the island nation and strike industrial targets as far north as Formosa.[4] In April 1945, it earned a second DUC during an attack on Saigon, French Indochina.[2]
In July 1945, the squadron moved to Ie Shima Airfield in the Ryuku Islands, from which it was able to attack shipping in the Sea of Japan and carry out a few raids on Kyushu. Following V-J Day, the squadron remained at Ie Shima until December, when it returned to the United States and was inactivated at the port of embarkation on 19 December 1945.[2][4]
Tactical Air Command
editThe squadron was reactivated at Langley Air Force Base, Virginia in October 1957 when the 345th Bombardment Wing replaced the 345th Bombardment Group there. The squadron was equipped with Martin B-57B Canberra jet bombers. It trained to maintain combat proficiency in locating, attacking, and destroying targets from all altitudes and under all conditions of weather and light.[6] It was inactivated at Langley on 25 June 1959 in connection with the phaseout of the Canberra from Tactical Air Command.[2][7]
