FPS-117

1998

The RSAF introduced the FPS-117 radar, enhancing 24/7 airspace defence with long-range, high-precision detection.

The FPS-117 is an advanced, all-weather, three-dimensional long-range radar with high precision detection capabilities. Operated by 201 Squadron, it replaced the ITT RS-321 radar to become the main surveillance system for round-the-clock defence of Singapore’s airspace.
