Singapore Army Adds SIGMA 155mm Howitzer and Precision Strike System for Faster Target Engagement.

The Singapore Army is introducing the truck-mounted SIGMA 155mm L/52 howitzer and a new Precision Land Shooter in Singapore to modernize its artillery and land-based fires. The SIGMA will progressively replace the tracked SSPH Primus and towed FH-2000, while the Precision Land Shooter adds another option for rapid and more precise target engagement.

Singapore is reshaping its land-based firepower around the SIGMA 155mm L/52 and the Precision Land Shooter, combining a new truck-mounted artillery system with a mobile precision-strike capability. The SIGMA is intended to replace both tracked and towed artillery currently in service, while the Precision Land Shooter expands the Army's options for engaging targets rapidly and with greater precision.

This development forms part of the broader modernization of the 6th Singapore Division, a combined-arms formation that already operates Leopard 2SG tanks, HIMARS rocket launchers, and several intelligence and targeting capabilities. The simultaneous introduction of a new automated howitzer and a lighter precision-strike weapon gives the division a wider range of fires, extending from conventional artillery support to the selective engagement of higher-value targets.

The systems made their first public appearance in images released by the Singapore Army on October 2, 2026, during events marking the 50th anniversary of the 6th Singapore Division. Singapore's Ministry of Defence later confirmed that the Truck Mounted Gun will become the Army's next-generation howitzer and will be introduced progressively to replace the SSPH Primus and FH-2000. MINDEF also confirmed the role of the Precision Land Shooter, without identifying the manufacturer or releasing detailed technical specifications.

The new howitzer closely matches the SIGMA 155mm L/52 developed by Elbit Systems. In 2021, the Israeli company announced a $106 million contract to supply the fully automated system to an unidentified customer in the Asia-Pacific region, with deliveries scheduled over five years. That timeline is consistent with the weapon's appearance in Singapore, although MINDEF has not officially identified the manufacturer.

Automation is one of the main changes introduced by the SIGMA. The system uses a 155mm 52-calibre gun paired with an automatic loading mechanism capable of selecting and loading the projectile, modular charges, and primer required for each fire mission. According to data released by Elbit Systems and reported by Asian Military Review, the vehicle can carry 40 projectiles, 216 modular charge units, and 45 primers in automated magazines. Its stated maximum rate of fire is eight rounds per minute.

The SIGMA also has a Multiple Round Simultaneous Impact capability, allowing several projectiles to be fired on different trajectories so they reach the target within a short interval. Transition from travelling configuration to firing position reportedly takes around 30 seconds. By comparison, Singapore Army data indicates that the FH-2000 requires about 90 seconds to deploy or leave its firing position. Shortening this exposure period can reduce vulnerability to counter-battery radars and reconnaissance drones tasked with locating artillery after firing begins.

The Precision Land Shooter complements this development with a lighter and more selective strike option. The system displayed by the 6th Singapore Division is based on a utility vehicle carrying nine launch canisters in a 3x3 arrangement. Its exact weapon has not been officially identified. Janes noted an external resemblance to launchers associated with Rafael's Spike NLOS family, while Asian Military Review described it as a loitering munition. Both assessments should remain cautious at this stage, as Singapore has only confirmed its role as a precision-strike capability.

At the tactical level, both systems fit directly into the structure of the 6th Singapore Division's Headquarters Sense & Strike, which is responsible for linking intelligence assets, sensors and fires with manoeuvre units. The SIGMA provides an option for missions requiring sustained artillery fire with a shorter deployment cycle, while the Precision Land Shooter could be used against more specific targets without committing a full 155mm battery or HIMARS launchers. This combination gives commanders greater flexibility in matching weapons to targets while supporting dispersed operations and rapid movement after firing.

The joint replacement of the Primus and FH-2000 also shows that Singapore is seeking to reduce the manpower and logistical demands associated with its artillery force. The Primus retains the advantage of tracked mobility alongside armoured formations, but relies on a heavier architecture. The FH-2000, for its part, requires more personnel and more time to deploy. An automated truck-mounted system is better suited to an army with limited manpower operating from a territory where road mobility remains important.

For Singapore, the introduction of the SIGMA and Precision Land Shooter responds above all to the strategic constraints of a small state with limited geographic depth, where artillery units have relatively little space to disperse and survive after opening fire. The SIGMA's ability to deploy quickly, fire, and relocate can reduce exposure to reconnaissance drones and counter-battery systems that are becoming more widespread across the region. The Precision Land Shooter adds a more selective strike option between 155mm artillery and the HIMARS systems already in service. Together, these capabilities allow Singapore to diversify its land-based fires while maintaining a relatively compact force in an Asian security environment where precision, targeting speed, and launcher survivability are becoming increasingly important.
