The 9th Bombardment Group was a bombardment group that spent much of the war in Panama, the Caribbean and the US, before moving to Tinian at the start of 1945 where it spent the last year of the war operating B-29s against Japan.

The group was formed as a reconnaissance unit in 1922 and didn't become a bombardment group until 1935. It was home based until 1940 when it moved to Panama to defend the canal (providing the only heavy bombers in December 1941), and also used its Flying Fortresses for anti-submarine patrols over the Caribbean. In October 1941 the squadron moved to Trinidad, where it remained for the next year.

Between October 1942 and November 1944 the group was based in the US, where it flew a mix of aircraft types and was used as a training unit.

This changed in March 1944 when the group became a Very Heavy bombardment unit and converted to the B-29. It moved to the Pacific at the end of 1944 and joined the Twentieth Air Force on Tinian (where it would be based for the rest of the war). The group was part of the 313th Bombardment Wing, the first B-29 wing to move onto the North Field on Tinian. Operations began in January 1945 with an attack on Maug (in the northern Mariana Islands).

The group spent most of the rest of the war taking part in the heavy bombing campaign against Japan. It was an awarded a Distinguished Unit Citation for an attack on Kawasaki in April 1945. At first the group operated as a high altitude daylight unit, but from March night incendiary raids began.

In April-May 1945 the group was diverted to the Okinawa campaign, attacking Japanese airfields that were being used to against the American invasion force. The group also dropped mines in Japanese waters, and received a second DUC for mining dropping in the Inland Sea in 1945.

After the end of the fighting the group dropped food and supplies to Allied POWs, as well as over flying the Japanese home islands. It remained on Tinian until April 1946 when it moved to the Philippines. The group remained in the Far East until it was inactivated on Guam in 1948.
