449th CSG

The 449th Combat Sustainment Group (CSG) was a United States Air Force unit with a legacy dating back to World War II. Originally activated as the 449th Bombardment Group (Heavy) in 1943, it flew B-24 Liberators in strategic bombing missions over Europe. After the war, the group was inactivated and later re-designated several times, ultimately becoming the 449th Combat Sustainment Group in the 21st century. The unit’s mission focused on providing logistics, sustainment, and support to Air Force operations before its inactivation in 2010 as part of an Air Force logistics restructuring.
