The wing was first activated at Langley Field, Virginia, as the 29th Bombardment Group in January 1940.
with the 6th, 43d and 52d Bombardment Squadrons assigned as its original components.
Its organization was part of the pre-World War II buildup of the United States Army Air Corps after the breakout of war in Europe.
 In May, it moved to MacDill Field, Florida, where it was equipped with a mix of pre-production YB-17s and early model Boeing B-17 Flying Fortresses and Douglas B-18 Bolos.

In September 1941, the group expanded whan a fourth squadron, the 21st Reconnaissance Squadron, was attached to it.
The group was still at MacDill when the Japanese attacked Pearl Harbor, and it began to fly antisubmarine patrol missions in the Gulf of Mexico from January 1942.
While the group was engaged in antisubmarine patrols, its 21st Reconnaisssance Squadron was renamed the 411th Bombardment Squadron, recognizing that its mission no longer differed from that of the other three squadrons in the group.
By the summer of 1942, the U-boat threat in the Gulf began to diminish, with all German submarines being withdrawn from the area by September.

No longer needed in the Gulf, the group moved to Gowen Field, Idaho, where it became an Operational Training Unit (OTU) The OTU program involved the use of an oversized parent unit to provide cadres to "satellite groups".
The 96th, 381st, 384th and 388th Bombardment Groups were all formed at Gowen in the second half of 1942.

In 1943, the 29th Group exchanged its B-17s for Consolidated B-24 Liberators.
 The group mission also changed as the Army Air Forces' (AAF) need for new units diminished and its need for replacements increased.
 The group became a Replacement Training Unit (RTU).
Like OTUs, RTUs were oversized units, but their mission was to train individual pilots and aircrews.
 However, standard military units, like the 29th Group, were based on relatively inflexible tables of organization, and were not proving well adapted to the training mission.
 Accordingly, the AAF adopted a more functional system in which each base was organized into a separate numbered unit.
The 29th Bombardment Group and its four squadrons were inactivated.
 Its personnel and equipment, along with that of supporting units at Gowen Field were combined into the 212th AAF Base Unit (Combat Crew Training School, Heavy) on 1 April 1944.
