The 309th Bombardment Group was a training group that served in the United States from early in 1942 until it was disbanded in the spring of 1944.
The group was formed on 28 January 1942 and became part of the Third Air Force. It was equipped with the B-25 Mitchell, and at first served as an operational training group, preparing entire groups of aircrew for entry to combat.
Once the USAAF was engaged in heavy combat it began to need replacements for casualties in existing units more than entire new units, and so the 309th became a replacement training group. This time it was preparing individual crews to join existing units or individual airmen to join existing crews that had lost a member.
The group was active for just over two years, from its activation in March 1942 until it was disbanded on 1 May 1944.
