The AN/FPS-35 radar was a long range radar used in the early 1960s.

Sperry Corporation built 12 long range radars (picking up objects 200 miles away) in the 1960s to succeed existing Semi Automatic Ground Environment (SAGE) to provide enhanced electronic counter countermeasures (ECM). The systems operated at 420 to 450 MHz. The antennas weighed 70 to 80 tons and had numerous problems. The concrete tower bases were 80 feet high.

All of the radars have been dismantled except for the one at Camp Hero on the eastern tip of Long Island, New York. Boaters on Long Island Sound lobbied to save it since the massive radar was a better landmark than the Montauk Point Lighthouse.

The radar complex is now part of Camp Hero State Park which adjoins Montauk Point State Park. The radar has worked its way into an urban legend that it was used in time travel experiments called the Montauk Project.
