The 73rd Aviation Company (Airplane Surveillance) (Light) was activated at Fort Rucker, Alabama, on 27 March, 1963, with Personnel Fill Date 15 May, and Readiness Date 24 May, and Equipment Readiness Date 20 May, 1963. The Department of the Army priority allocation of effort insured the highest degree of cooperation. At the time of departure from Fort Rucker for Vietnam, on 28 May, 1963, there were 98% officers and 96% enlisted men present for duty. All personnel received highly concentrated mission training, in the short time available, and were in fact ready to perform the unit's stated mission. The Company was air transported by MATS from Maxwell AFB, Alabama to Saigon, Vietnam. There was no finalized stationing plan or mission for the unit upon its arrival in Vietnam. The Company was temporarily located at three sites - Saigon, Vung Tau, and Nha Trang - for billeting purposes, awaiting mission and stationing disposition by Headquarters, Military Assistance Command, Vietnam (MACV). On 9 June, 1963, the Company was assigned the mission of providing an Aerial Surveillance Section per Army of Republic of Vietnam (ARVN) Division (3 aircraft each) and one section in support of Hqs, Special Forces. Also, on same date, the Company was augmented with 10 TO-1D's; total 32 aircraft, VOCG, USASCV, and J-3 MACV.

On 10 June, 63, the first aircraft was received from Air Vietnam; on 23 July, the 32d aircraft was received. On 20 June, the initial Aerial Surveillance Platoon was deployed in the 4th ARVN Corps area. From the initial deployment date (20 June 1963) through 30 Sept 1964, the Company accomplished over 45,000 missions, logging over 43,000 hours, average flying hours per month per assigned aircraft 100, average monthly aircraft availability 90%. The high sustained aircraft availability rate was noted by the Deputy Secretary of the Army. Several were shot down and unit aircraft were hit by enemy ground fire on more than 85 occasions. Operational results were most gratifying. The Company was favorably noticed by the Department of Army Flight Safety Team for its flight safety record. There were nine pilot error accidents in over 45,000 hours of flying. Other accidents were combat damage connected.

The Unit was recommended by the supported Commanders for the award of the Distinguished Unit Citation, and was approved by CG, USMACV on 19 March 1964 for the award of Meritorious Unit Citation since the award of Distinguished Unit Citation is currently not authorized. The Meritorious Unit Citation was presented to the Company by General W. C. Westmoreland at ceremonies in Nha Trang on 18 July 1964. This represented the first such award to be presented to a unit since the Korean War, and in addition, the 73rd was the first aviation unit to receive the coveted distinction in Vietnam.
