United States approves US$73m HIMARS upgrade for Singapore artillery systems

The United States Department of State has approved Singapore’s request to upgrade its M142 High Mobility Artillery Rocket Systems (HIMARS) in a deal estimated at US$73 million.

The approval was confirmed in a press release dated 15 June 2026.

The United States Department of State stated that the Government of Singapore had requested to purchase eighteen Common Fire Control System (CFCS) upgrade kits for the rocket artillery platform.

The systems are intended to enhance command, control and targeting functions across existing launchers.

Scope of proposed sale

The proposed package extends beyond the CFCS upgrade kits and includes a range of associated support components.

These include support equipment, technical documentation, spare parts, training, and both United States Government and contractor technical assistance.

Additional elements outlined by the United States Department of State include engineering and logistics support services, field office support, and other related logistics and programme support elements. Officials noted that the sale incorporates a full suite of sustainment measures intended to ensure operational continuity.

According to the United States Department of State, “The Government of Singapore has requested to buy eighteen (18) Common Fire Control System upgrade kits for the M142 High Mobility Artillery Rocket System.”

Singapore defence perspective

According to state media CNA, Singapore’s Ministry of Defence (MINDEF Singapore) stated on 19 June that the HIMARS system has been in service with the Singapore Armed Forces since 2010 as a land-based precision strike asset.

MINDEF said, “As the Singapore Armed Forces continues its modernisation efforts, the HIMARS remains a critical component of its operational capabilities, and will undergo upgrades to ensure it remains capable of meeting evolving operational and training requirements in the years ahead.”

The ministry added that the upgrade programme supports ongoing efforts to maintain readiness and training effectiveness within the artillery formation.

Technical capabilities and system role

According to MINDEF Singapore’s published specifications, the HIMARS launcher typically fires six 227mm surface-to-surface guided rockets capable of striking targets up to 70km away.

Each rocket carries a 90kg controlled fragmentation high explosive unitary warhead.

The system can be prepared for firing in under 20 seconds, while a full salvo of six rockets can be launched within approximately 45 seconds.

Defence publications describe the CFCS upgrade as a digital processing enhancement designed to improve targeting accuracy and operational efficiency.

The proposed upgrade also aims to strengthen command-and-control integration and improve overall launcher reliability, particularly in network-centric operational environments.

Regional context and prior procurement

The United States Department of State said the decision “will not alter the basic military balance in the region”, while emphasising that the upgrade strengthens a strategic defence partnership.

The department further stated that the proposed sale will enhance United States foreign policy and national security objectives by improving the security of a strategic partner described as “an important force for political stability and economic progress in Asia”.

The approval follows a separate HIMARS-related procurement announced by MINDEF Singapore in April, which involved the acquisition of M30A2 GMLRS Alternative Warhead pods valued at approximately US$83.1 million, according to the United States Department of State.

In March 2025, then-Defence Minister Dr Ng Eng Hen noted that Singapore’s HIMARS systems would be upgraded with more capable munitions to meet evolving operational requirements.

Dr Ng highlighted the effectiveness of HIMARS in recent conflicts, particularly in Ukraine’s ongoing war with Russia, and stressed its importance to Singapore’s defence.

The United States Department of State identified Lockheed Martin, based in Dallas, Texas, as the principal contractor for the upgrade programme.

The package includes contractor technical support and logistics coordination as part of the broader sustainment framework.

Singapore has operated the HIMARS platform since the early 2010s, following its initial request for 18 launchers in 2007.

The systems entered operational service under the Singapore Artillery formation in 2011.

Current estimates suggest the Singapore Armed Forces operates approximately 18 to 24 HIMARS launchers within the 23rd Battalion, Singapore Artillery, forming a key component of its long-range precision strike capability.
