In March 1944 the 348th was disbanded when the AAF found that standard military units, based on relatively inflexible tables of organization were proving less well adapted to the training mission. Accordingly, a more functional system was adopted in which each base was organized into a separate numbered unit during a reorganization of units in the United States. The squadron's personnel and equipment were transferred to Squadron B of the 450th Army Air Forces Base Unit (Night Fighter Replacement Training Unit).

606th Air Commando Squadron which transitioned to other aircraft. The primary mission of the 609th was night interdiction of truck traffic along the Ho Chi Minh Trail. Its call sign for these missions was "Nimrod", inherited from the 606th and other squadrons that had flown that mission, and "The Nimrods" soon became the squadron's nickname. The squadron's A-26 aircraft carried tail letters "TA".
On 1 August 1968, all Air Commando Wings were redesignated as Special Operations Units, and the 56th Air Commando Wing became the 56th Special Operations Wing, with the 609th Air Commando Squadron becoming the 609th Special Operations Squadron.

The 609th was inactivated on 1 December 1969. The squadron's losses had been heavy, and it was awarded the
