Receiving the Defense Secretary's approval on 21 July, the Air Force directed the Corps of Engineers to proceed with construction.

Completed in early 1951, and fully manned and operational when the 765th Aircraft Control and Warning Squadron brought Charleston AFS to life in April 1952[1] and assumed coverage that had been provided by a temporary Lashup Radar Network site at Dow AFB (L-l).

The award is for the period 1 Jan 1959, and 30 April 1963, during which time the unit demonstrated "exceptionally meritorious service in support of military operations".

Basic mission of the unit, situated atop Bull Hill in Central Maine, is to provide search and height data on aircraft to the Bangor North American and Bangor Air Defense Sectors headquarters Semi-Automatic Ground Environment (SAGE) Direction Center at Topsham Air Force Station.

Factors involved which led to the award were primarily the quality and quantity of radar inputs and air-to-ground communication capability provided the SAGE Direction Center at Topsham AFS.

The supply account record review for the unit was judged the "Best In 26th Air Division" in September, 1961, by Air Defense Command headquarters personnel who accomplished their review in three hours rather than two days which was standard time at other installations; the 26th Civil Engineering section in July, 1962, indicated that the station was the "Best Maintained" in the division; the unit dispensary was rated "Best In Division"; and the Communication-Electronics section, through continuous outstanding performance of mission requirements, is considered one of the "Best In Air Defense Command."

Consecutive reports by the USAF Inspector General's office from 1960 through 1962 relate better than normal degree of efficiency by the unit; the squadron was the first to win the 26th Air Division Commander's Recreation Trophy for morale and team spirit in September, 1962; and the unit is well respected by the surrounding civilian community populace because of an active public relations program by all personnel.

Over the years, the equipment at the station was upgraded or modified to improve the efficiency and accuracy of the information gathered by the radars.
