Boston Air Defense Sector
military unit
The Boston Air Defense Sector (BADS) is an inactive United States Air Force Air Defense Command (ADC) organization. Its last assignment was with the 26th Air Division at Hancock Field, New York.
History
BADS was established in 1956 at Stewart Air Force Base (AFB), New York as the 4622nd Air Defense Wing pending completion of the new Semi Automatic Ground Environment (SAGE) Direction Center (DC-02) and Combat Center (CC-04) which became operational 15 September 1958. DC-02 was equipped with dual AN/FSQ-7 Computers. Early in 1957, the wing was redesignated as the Boston Air Defense Sector.
The mission of the BADS was to provide air defense over New England initially in an area covering southern Maine, southern New Hampshire, southern Vermont, Massachusetts, northern Rhode Island and Connecticut and part of New York. The day-to-day operations of the command were to train and maintain tactical units flying jet interceptor aircraft (North American F-86 Sabre, Northrop F-89 Scorpion, Lockheed F-94 Starfire, Convair F-102 Delta Dagger, Lockheed F-104 Starfighter) and operating radars and interceptor missiles (Boeing CIM-10 Bomarc) in a state of readiness with training missions and series of exercises with Strategic Air Command and other units simulating interceptions of incoming enemy aircraft. From 1960 to 1962, BADS was also responsible for a squadron in Nova Scotia that controlled interceptors "manually" (by voice instructions rather than by data link).
The Otis Bomarc SAMs (26th ADMS) were directed from the Air Defense Direction Center (CC-01/DC-03) at Hancock Air Force Base, Syracuse, New York. Continental Air Defense Command, in setting up the air defence command and control system in the area, had designated the Boston Air Defense Sector as 1 of 4 sectors in the 26th Air Division "effective April 1, 1958" DC-03 was operational on 1 December 1958; and the division was the 1st operational in the SAGE Air Defense Network — 1 January 1959 (CC-01 was the "first SAGE regional battle post", beginning operations "in early 1959".)
The radar network supporting BADS required near-total coverage, with radar beams overlapping and sites no more than 25 miles apart.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Boston Air Defense Sector”, the useful work is to connect “military unit” to the records capable of establishing context and consequence.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Jan 2, 2026.

The first chronological checks are 1956, 1958, 1957 and 1960.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
