Singapore is upgrading its HIMARS rocket launchers to integrate more powerful missiles.

The country’s Ministry of Defense said that HIMARS MLRS has been in service with Singapore since 2010.

“The Singapore Army’s High Mobility Rocket System (HIMARS), […] battle-tested by Ukraine in the Russia-Ukraine War, will also be upgraded to integrate more capable rockets,” the country’s Ministry of Defense stated.

The upgrade is expected to enable the launchers to use the new high-precision extended-range GMLRS-ER missiles.

There is also a possibility that the launchers will be able to fire short-range Precision Strike Missile (PrSM) ballistic missiles.

The GMLRS-ER high-precision rocket launchers are an improved version of the well-known and actively used in Ukraine M30A2 and M31A2 GMLRS.

The improved ones have an increased range of up to 150 km (compared to 90 km of conventional GMLRS).

At the same time, each transport and launch container, as before, will hold six missiles.

The Precision Strike Missile (PrSM) short-range ballistic missile was developed to replace the MGM-140 ATACMS missiles and is capable of hitting targets at a distance of up to 500 km (compared to 300 km in ATACMS).

At the same time, the PrSM carries a much smaller warhead weighing only 91 kg, which should be compensated by high accuracy.

In total, 18 M142 HIMARS launchers and containers with missiles have been delivered to the Singaporean army.

In 2017, the country’s military received a new mobile battery command post from Lockheed Martin Corporation.
