History

B-29 Superfortress operations against Japan

Established as a B-29 Superfortress heavy bomb group in early 1944; trained under Second Air Force in Nebraska. Initially trained with B-17 Flying Fortresses until B-29 aircraft were manufactured and assigned to the unit.

Deployed to Tinian, Northern Mariana Islands in December 1944. Entered combat by flying navigational escort for a major attack force bound for Iwo Jima. The squadron then struck Tokyo and other major Japanese cities and facilities during daylight high-altitude bombing raids, with crippling, non-stop incendiary raids which destroyed lines of communication, supply, and numerous kamikaze bases. On 25 May 1945, the squadron flew a low-altitude night mission through alerted enemy defenses to drop incendiary bombs on Tokyo, for which they received their first Distinguished Unit Citation.

In addition to incendiary raids, the 40th also participated in mining operations. By mining harbors in Japan and Korea in July 1945, the squadron contributed to the blockade of the Japanese Empire earning their second Distinguished Unit Citation. The 40th's final World War II mission came on 14 August 1945, with the dropping of 500-pound general purpose bombs on the Marifu railroad yards at Iwakuni.

With the war over, the squadron dropped food and supplies to Allied prisoners of war and took part in show-of-force flights over Japan. Aircraft and were returned to the United States in late 1945; unit remained assigned to 20th Air Force primarily as an administrative unit where it was unequipped; finally inactivated in 1948.

Strategic Air Command

Reactivated in January 1951 due to expansion of the Air Force due to the Cold War. Equipped with B-36 Peacemaker intercontinental strategic bombers. Initially was equipped with B-36Fs. Later Featherweight III B-36Js were added, the squadron operating both types. Carried blue stripe on the tip of the vertical stabilizer; the lip of the jet intakes and the "nose cone" of the jet itself along with triangle-R tail code. SAC eliminated tail codes in 1953. In September 1957, the B-36s were replaced with B-52E Stratofortress aircraft and all squadron markings were eliminated. Continued strategic bombardment training until 1967 when the squadron was inactivated with the closing of Walker AFB.

Reactivated as a provisional B-52H strategic bomb squadron as part of the Global War on Terrorism in 2002. Engaged in combat operations over Iraq and Afghanistan. Suspected to have ended combat operations in 2006; current status is undetermined.
