Lockheed Martin is positioning its TPY-4 ground-based long-range surveillance radar for the Republic of Singapore Air Force’s (RSAF’s) air-defence requirements.

Chandra Marshall, vice-president for radar and sensor systems at Lockheed Martin, confirmed the matter during a briefing for media representatives on 14 February. The briefing was held as a run-up to the Singapore Airshow, which will be held from 20 to 25 February.

The RSAF operates the FPS-117 long-range surveillance radar as part of a multilayered network of air-defence sensors that the service refers to as the island air defence (IAD) system. The FPS-117 has an effective detection range of up to 250 n miles (463 km).

“The TPY-4 is the premier ground-based long-range air surveillance radar in the world. It really represents a generational leap in performance over the FPS-117 radars that Singapore currently operates today,” said Marshall, who also oversees rotary and mission systems at Lockheed Martin.
