Singapore Army commissions TPQ-53 S-band WLR system

The Singapore Army has commissioned the Lockheed Martin TPQ-53 weapon locating radar (WLR) system to replace its current fleet of X-band (8–12.5 GHz range) ThalesRaytheonSystems TPQ-36 and TPQ-37 WLRs that have been in service since 1986 and 1991 respectively.

The new radar system was commissioned by defence minister Ng Eng Hen at Headquarters 6th Singapore Division/Headquarters Sense and Strike (HQ 6 Div/HQ SS) at Mandai Hill Camp on 28 June. Unlike the US Army, which operates the type under the AN/TPQ-53 designation and integrated on five-tonne M1083 6×6 medium tactical vehicles (MTVs), the radar's active array assembly in the Singapore version is mounted on a four-wheeled trailer and towed by a MAN TGS 6×6 truck.

The Ministry of Defence (MINDEF) noted that the new system provides improved acquisition and target identification of rocket, artillery, and mortar (RAM) threats out to a maximum range of up to 60 km – up from 50 km previously – along with improved accuracy. Unlike the earlier radar systems that can only operate in staring mode, the TPQ-53 can operate in both rotating and staring modes for operations that require all-round force protection.

“This provides early warning, protects forces on the ground, and enables swift destruction of hostile threats,” said MINDEF in a 30 June statement.

“The [radar] has improved locating accuracy to better deliver counter attacks on enemy artillery forces,” it added, noting that the highly automated system requires about 30% less manpower to operate as compared with its predecessors. “This also enhances situational awareness and increases survivability of ground troops.”
