Description:
The SSPH (Singapore Self-Propelled Howitzer) 1 Primus is a lightweight 155mm 39-caliber howitzer designed to meet the requirements of the Armed Forces of Singapore. SSPH 1 howitzer consists of a tracked chassis with a 155mm gun compliant with Joint Ballistic Memorandum of Understand and fully compatible with all NATO ammunition.
The 30 tons class SSPH1 howitzer is powered by a 550-hp diesel engine. It fires 3 rounds within 20 seconds and provides a burst rate of 6 rounds per minute. The fire control system uses the latest digital technology to effectively and precisely deliver artillery rounds on the battlefield.
The Primus howitzer maximum range is 19km firing unassisted projectiles, while that figure increases dramatically to 30 kilometers with rocket assisted projectiles.
The SSPH1 Primus self-propelled howitzer entered service with Singapore artillery units in late November 2003.
