4713th Defense Systems Evaluation Squadron

The squadron was organized as the 4713th Radar Evaluation Flight at Griffiss Air Force Base, New York in March 1954, assigned to Eastern Air Defense Force and equipped with Boeing B-29 Superfortresses.Cornett & Johnson, p. 112 The primary mission of the squadron was to provide electronic countermeasure (ECM) training and evaluation services to Air Defense Command's (ADC) aircraft control and warning squadrons. It also had a mobilization mission to provide electronic warfare support to combatant commands.

The squadron soon added the TB-29 model of the Superfortress, and some North American TB-25 Mitchells to its strength. The B-29s and B-25s contained an assortment of radar jamming devices to provide the required ECM and a Douglas C-47 Skytrain was used as a support aircraft to ferry personnel and equipment. During the period that the 4713th operated these aircraft, they provided the operators at ADC radar squadrons with thousands of hours of ECM training.{{citation needed|date=December 2020}} On 8 July 1958, ADC expanded the flight to a squadron.

In August 1959, the squadron moved to Stewart Air Force Base, New York. By this time the World War II aircraft flown by the squadron were becoming expensive to operate, needing excessive amounts of maintenance to remain airworthy suffering from a lack of spare parts. At Stewart, the squadron began to equip with the Martin B-57 Canberra, originally developed as a medium bomber, but which was being phased out in favor of the North American F-100 Super Sabre.{{citation needed|date=December 2020}} Some of these B-57s were reassigned to the squadron to replace the B-29s and B-25s.

In addition to the ECM training for Radar Sites, the B-57s could operate at altitudes over 40,000 feet and train fighter interceptor squadrons. Exercises were conducted with North American F-86D Sabre, Lockheed F-94C Starfire, and Northrop F-89D Scorpions. Later, the B-57Es were adapted to ECM and faker target aircraft against Convair F-102 Delta Dagger and Convair F-106 Delta Dart interceptors. Following a new electronics fit in the 1960s, the B-57Es were redesignated EB-57E.{{citation needed|date=December 2020}} These specially-equipped EB-57Es were operated until 1974 when the squadron was inactivated.

As Stewart was being transferred to the United States Army, the squadron moved to Otis Air Force Base, Massachusetts in December 1969. However, its stay at Otis was short, as Otis was being turned over to the Massachusetts Air National Guard and the squadron moved again to Westover Air Force Base, Massachusetts, a Strategic Air Command baseMueller, p. 578 in September 1972. However, in May 1974, Westover was transferred to the Air Force Reserve. The reserves were not funded or manned to support regular units on their installations, and the decision was made to inactivate the squadron in April.
