The first
418th Bombardment Group was activated in August 1943 at
Lake Charles Army Air Field, Louisiana. It was apparently only minimally manned and never received aircraft before it was disbanded in September. The second
418th Bombardment Group was activated in March 1944 at
Alamogordo Army Airfield, New Mexico as a
Replacement Training Unit for
Boeing B-29 Superfortress aircrews. However, even as the unit was being activated, the
Army Air Forces (AAF) had determined that standard military units like the group, based on relatively inflexible
tables of organization not well adapted to the training mission. The AAF had already determined to change to a more functional system in which each base was organized into a separate numbered unit. The 418th was disbanded and bomber training activities at Alamogordo were assigned to the new 231st AAF Base Unit (Combat Crew Training Station, Bombardment, Heavy) The
United States Air Force consolidated the two groups in April 1958. but has not been active since. ==Lineage==
