Editing M51 Skysweeper (section)

==Deployment==
Skysweeper deployment began in the early 1950s.  Skysweeper was also part of the [[Army Anti-Aircraft Command]] (ARAACOM) in the U.S near targets that would have to be attacked by low-altitude aircraft. During the 1950s the Army formed the Army Anti-Aircraft Command (ARAACOM) to operate batteries of anti-aircraft guns and missiles. Most ARAACOM deployments were around cities and used the 90&nbsp;mm and 120&nbsp;mm guns, as well as the [[Nike Ajax]] missile defense.

[[CONUS]] had 896 120mm and 75mm ''Sky Sweepers'' in service in 1953. Most were along the NE Corridor from Boston to District of Columbia and in Washington State.

In 1957, ARAACOM was renamed to US Army Air Defense Command (USARADCOM, ARADCOM in 1961) and, ARAACOM started to dramatically replace gun sites with fewer missile sites ([[List of Nike missile locations#Florida|ARADCOM ended in 1975]]).

By the end of 1957 Skysweeper battalions remained at [[Sault Ste. Marie, Michigan]], to protect the [[Soo Locks]] (one battalion), [[Savannah River Site]] (two), and one 90mm and two Skysweeper battalions at [[Thule Air Base]], [[Greenland]] (all were removed by 1959). The last overseas Skysweeper were deactivated in the mid-1970s, being wholly replaced by other more advanced anti-air missile systems.
