About this Unit
The 657th Radar Squadron was a United States Air Force unit activated in 1949 as part of the nation’s expanding air defense network during the early Cold War. Stationed at Houma Air Force Station, Louisiana, the squadron operated ground-based radar systems to detect, track, and identify potential airborne threats approaching the Gulf Coast region. As part of the Air Defense Command, the 657th played a pivotal role in continental air surveillance and coordination with interceptor aircraft. The unit remained in service until its inactivation in 1970, reflecting changes in national defense priorities and advances in radar and missile technology.
Historical Facts
•
Formation and Role: The 657th Radar Squadron was established in 1949 as part of the United States Air Force’s Air Defense Command and primarily tasked with ground-controlled interception and airspace surveillance during the Cold War.
•
Location: The squadron was based at Houma Air Force Station, near Houma, Louisiana, a key site for monitoring the Gulf of Mexico approaches for potential Soviet threats.
•
SAGE System Integration: In the early 1960s, the unit was integrated into the Semi-Automatic Ground Environment (SAGE) system, a revolutionary computer network that automated the detection and interception of enemy aircraft.
•
Radar Technology: The squadron operated several radar systems over its history, including the AN/FPS-20 search radar and AN/FPS-6 height-finder radars, which were state-of-the-art at the time.
•
Cuban Missile Crisis Vigilance: During the Cuban Missile Crisis in October 1962, the 657th was on high alert, scanning for any Soviet bomber or missile activity approaching the southern United States.
•
Air Defense Identification Zone (ADIZ): The squadron played a crucial role in monitoring and maintaining the southern ADIZ, identifying and tracking all aircraft entering U.S. airspace from the Gulf region.
•
Friendly Skies: Personnel from the squadron often coordinated with both civilian air traffic control and NORAD, ensuring that commercial flights and unidentified aircraft were properly distinguished.
•
Deactivation: The squadron was inactivated on June 30, 1980, as advances in satellite and over-the-horizon radar made many ground-based stations obsolete.
•
Legacy: Many veterans of the 657th went on to serve in other radar and air defense roles, contributing their expertise to the evolving American air defense network.
•
Preserved Site: While much of the original Houma AFS has been redeveloped, some radar towers and buildings still remain, serving as reminders of the squadron’s role in Cold War defense.
