China North Industries Corporation (NORINCO) is marketing at the 2012 Zhuhai Airshow its wheeled CS/SA1 35mm Self-Propelled Anti-Aircraft Gun (SPAAG). Somewhat similar to the tracked PGZ07, but mounted on a 6 x 6 truck, the system has been designed against aircraft, helicopters, cruise missiles and unmanned aerial vehicles (UAVs).
The CS/SA1 SPAAG
has been integrated with the AF902A fire control system (FCS) and is able to direct missiles and towed
gun systems. The FCS features a roof-mounted 3D search
radar, a tracking radar below and an electro-optical day or night sensor
package for continuous operations in a jammed or passive mode environment.
The FCS comes with its own auxiliary power unit (APU) and can continuously operate for up to 12
hours. The surveillance radar has a maximum
detection and tracking range against aircraft of up to 35 km and 15 km against cruise missiles. Maximum target detection height is listed as 6 km.
The twin guns are based on the 35mm guns originally developed by Oerlikon Contraves. The guns have an effective range of 4000 meters and a maximum range of 8000 meters. Effective ceiling is 3500 meters. They can fire a variety of 35 x 228 rounds, including High Explosive Incendiary (HEI), Semi Armour Piercing High Explosive Incendiary (SAPHEI) and Frangible Armour Piercing Discarding Sabot (FAPDS).
NORINCO is also marketing Programmable Time Fuze Pre-fragmented (PTFP) rounds, which are similar to the Advanced Hit Efficiency And Destruction (AHEAD) rounds. PTFP rounds are programmed as they pass through
the muzzle coils located on each gun barrel. Each round releases more than 100 spin-stabilised tungsten projectiles in front of the target at a pre-determined distance
for maximum effect.
