609th Special Operations Squadron
The 609th Special Operations Squadron is an inactive United States Air Force unit. Its last assignment was with the 56th Special Operations Wing at Nakhon Phanom Royal Thai Navy Base, Thailand. The squadron served for two and a half years combat duty during the Vietnam War, primarily flying missions over the Ho Chi Minh Trail in Laos. It earned several decorations, including the Presidential Unit Citation, before it was inactivated in December 1969. The first predecessor of the squadron was the 349th Night Fighter Squadron, which served as a night fighter training unit in Florida and  California until it was disbanded in a reorganization of Army Air Forces training units and replaced by the 450th AAF Base Unit. The second predecessor of the 609th was the 329th Transport Squadron, which was organized overseas to provide airlift services in the Mediterranean Theater of Operations History. Night fighter training. The 349th Night Fighter Squadron was formed at Orlando Army Air Base, Florida in October 1942 as part of the Army Air Force School of Applied Tactics Fighter Command School from elements of the 81st Fighter Squadron. Its personnel were veteran American pilots trained by the Royal Air Force  in night interception operations. It was initially equipped with three Douglas DB-7s and twenty-three Douglas P-70s. Shortages in operational flying aircraft, spare parts and other issues kept flying training very rudimentary for the squadron's first classes that graduated in December 1942. As 1943 progressed additional aircraft and equipment arrived and the program expanded. In September, the first American-built dedicated night fighter began to arrive, the YP-61, and a few production Northrop P-61A Black Widows. In January 1944 the entire night fighter training program moved to Hammer Field, California and was placed under IV Fighter Command. The move  placed the squadron nearer to Northrop Aircraft manufacturing facility at Hawthorne, California. Most P-61 squadrons trained by the squadron were planned to deploy for operations in the Pacific and China Burma India Theaters. 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). Airlift in the Mediterranean Theater. The 329th Transport Squadron delivered cargo and mail throughout the Mediterranean Theater of Operations from its activation in March 1944 until it was inactivated in September 1945. The squadron was disbanded in 1948, then reconstituted in 1985 and consolidated with the 609th. Combat Operations During the Vietnam War. The 609th Special Operations Squadron was organized as the 609th Air Commando Squadron at Nakhon Phanom RTAFB, Thailand on 15 September 1967. It was assigned to the 56th Air Commando Wing. The  squadron flew the Douglas A-26 Invader, a twin engine attack bomber of WWII vintage. These aircraft were transferred from the 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 night interdiction tasks of the 609th were gradually taken over by squadrons flying Lockheed AC-130 gunships, and the A-26 aircraft were phased out of active service by November 1969. By the time the last four surviving A-26s were withdrawn at the unit stand down, the squadron had flown 7,159 combat missions, and been credited with destroying 4,268 enemy supply trucks. The 609th was inactivated on 1 December 1969. The squadron's losses had been heavy, and  it was awarded the Presidential Unit Citation for gallantry. The remains of two squadron pilots, Maj. James E. Sizemore and Maj. Howard V. Andre, shot down over Laos in 1969, were recovered in 2013 and buried at Arlington National Cemetery
