It was placed on inactive status on 23 September 1946, although a small cadre of Army and Air Force personnel (331 Composite Squadron) remained assigned to Alexandria Municipal Airport throughout the late 1940s.

With its subordinate 416th (activated 28 September 1970) and 431st Tactical Fighter Squadrons,[2] it absorbed returning North American F-100 Super Sabre aircraft of 31st TFW from Tuy Hoa Air Base South Vietnam.

[3] Alexandria (and later England) AFB was base for Air Defense Command interceptor and radar units along the Gulf Coast.

In addition to the fighter-interceptor squadron, England AFB part of the planned deployment by Air Defense Command of forty-four Mobile radar stations across the United States to support the permanent Radar network established during the Cold War for air defense of the United States.

As a GCI station, the squadron's role was to guide interceptor aircraft toward unidentified intruders picked up on the unit's radar scopes.

In addition to the main facility, Air Defense Command operated three AN/FPS-18 Gap Filler sites: England AFB was a planned Semi Automatic Ground Environment (SAGE) Data Center (DC) location, for the also-planned Shreveport Air-Defense Sector.

However, in March 1963 Air Defense Command ordered the site to close due to budget reductions and operations ceased on 23 April.
