The mounting hardware for the main gun allows for an elevation span of -5 to +75 degrees with full 360-degree traversal. Rate-of-fire is approximately six rounds maximum with sustained fire in the 2 rpm range and burst fire (over a 20 second span) in the 3 rpm range. Projectiles can reach out to 19 miles with rocket-assist.
The finalized hull structure features armor protection up to 25mm thick and a well-sloped glacis plate. Dimensions include a length of 33 feet (with gun forwards), a width of 9 feet, 10 inches, and a height to turret top of 10 feet, 9 inches. Combat weight is listed at 31 tons (short). The SSPH 1 chassis is believed to be based on that of the American M109 "Paladin" SPH.
Power to the vehicle is through a Detroit Diesel 6V 92TA series diesel-fueled engine developing 550 horsepower. This supplies the SSPH 1 with a maximum road speed of 31 miles per hour with a 220 mile road range. The powerpack is said to be similar to one already in use by the ST Kinetics Bionix Infantry Fighting Vehicle (IFV) detailed elsewhere on this site.
Since inception, the SSPH 1 has stocked the inventory of the Singapore Army through the 21st Battalion Singapore Artillery.
