The AN/FPS-6 radar, developed at RADC, was the first long-range height finder radar employed at all Semi-Automatic Ground Environment (SAGE) locations. This system had a maximum range of 200 nautical miles and a height-finding capacity of 75,000 feet within an angle limit of minus 2 to plus 32 degrees. The AN/FPS-90 is a modified AN/FPS-6B.
