Nike Hydac

Nike Hydac is the designation of an American sounding rocket with two stages, based upon the Nike Ajax system. The Nike Hydac was launched 87 times from many missile sites. Such sites were White Sands Missile Range, Poker Flat Research Range ("Poker Flats"), Kwajalein Missile Range, Cassino Site - Rio Grande Airport, Brazil and North Truro Air Force Station.

The directing agency for Nike Hydac was the Air Force Cambridge Research Laboratory, (AFCRL) Cambridge, Massachusetts. The AFCRL began its origins to the Cambridge Field Station in 1945 to analyze and study Massachusetts Institute of Technology (MIT) wartime efforts on electronic countermeasures and atmospheric research.
