Nike Ajax Bases

1. The best preserved Nike installation is site SF88L located in the Marin Headlands just west of the Golden Gate Bridge in San Francisco, California. The site is a museum, and contains the missile bunkers, and control area, as well as period uniforms and vehicles that would have operated at the site. The site has been preserved in the condition it was in at the time it was decommissioned in 1974. The site began as a Nike Ajax base and was later converted to Nike Hercules.
2. The second best preserved Nike installation is site NY-56 at Fort Hancock in Sandy Hook, New Jersey. The site has been restored and contains the original missile bunkers, as well as three Nike Ajax and a Nike Hercules on display. The site is on the National Register of Historic Places.
