The VERy LOng Range Tracking (VERLORT) S-band radar (2700 t0 2900 MHz) was an extended-range version of the SCR-584 - often credited as "the radar that won WW II".
For space missions, its range was increased from 650 Km to 4000 Km and the dish diameter from 1.8 m to 3 m; it was given a long name befitting its new space-tracking capabilities. The Red Lake (Woomera) Mercury tracking station used the more accurate AN/FPS-16 radar installed at Woomera for previous space activities.
The Verlort performed reliably for the six Mercury orbital missions at Muchea. It was then relocated to the new Gemini tracking station at Carnarvon as an acquisition aid and back-up for the even more accurate FPQ-6 radar to be installed there.
Although the Verlort was kept operational at Carnarvon for the first few missions it was soon taken off the operational list once the FPQ-6 proved its reliability and other acquisition methods also proved sufficient.
The SCR radars, developed at the MIT laboratories, were remarkable for MIT’s innovative mechanical solutions to radar operations that are now met by electronic methods in modern radars: see Technical Details
The SCR-584 pedestals and angle-control mechanisms were widely used by NASA as the basis of other antenna systems; for example, the VHF Acquisition Aid and Telemetry Antennas for the Mercury, Gemini and Apollo projects.
