Four sites initially protected the Spokane region and the Strategic Air Command Base at Fairchild. Nike Ajax Batteries were built and activated at (F-07) Spokane, (F-37) Cheney, and (F-45) Medical Lake in 1957; the fourth battery at (F-87) Deep Creek was built and activated in 1958. Medical Lake was converted to Hercules missiles in 1960 and 1961. Headquarters facilities were located at Fairchild.
The Seattle District of the Corps of Engineers had land acquisition, design, and construction supervision responsibilities. The Army deactivated the Nike Ajax batteries in 1960. The two Nike Hercules batteries remained activated until 1966.
