The 678th Air Defense Group is a disbanded United States Air Force organization. Its last assignment was with the 20th Air Division of Air Defense Command (ADC) at Tyndall Air Force Base, Florida. The group was formed in 1970 when ADC expanded its radar units that operated Backup Interceptor Control sites from squadron sized units. From 1977 until it was inactivated in 1983 the 678th was responsible for operating the Southern Air Defense System.

History[edit]

The group replaced the 678th Radar Squadron (SAGE) (formerly the 678th Aircraft Warning & Control Squadron) at Tyndall AFB in 1970.[1] The group operated a Backup Interceptor Control (BUIC) site with the mission to back up the centralized and vulnerable Semi-Automatic Ground Environment (SAGE) operations center at Gunter AFB.[2] The group provided air defense mission command and control from 1970 to 1983. It was a component of Aerospace Defense Command (ADC)'s (later transferred to Tactical Air Command (TAC)) Air Defense Weapons Center from 1974 to 1981. The group earned an Air Force Outstanding Unit Award for exceptionally meritorious service for the period 1 June 1970 through 1 June 1972.[3]

In 1969, the inadequacy of the radar coverage to the south of the United States had been dramatically illustrated whan a Cuban MiG-17 went undetected before it landed at Homestead AFB,[4] and two years later, an An-24 similarly arrived unanounced at New Orleans International Airport.[4] As a result, ADC established The Southern Air Defense System (SADS). Initially, the 630th Radar Squadron operated a manual control center at the Houston Air Route Traffic Control Center and the USAF added radars to supplement the existing Federal Aviation Administration coverage in the area.[4] In 1977, responsibility for operating the SADS control center was transferred to the group, which was operating the last BUIC III site in ADC.
