China develops SWS2 mobile air-defense system (a real drone killer)Posted: July 7, 2016

China North Industries Corporation (NORINCO) has released details of its latest SWS2 self-propelled anti-aircraft gun/surface-to-air (SPAAG/SAM) system, which it is now offering for export.
It is based on an 8×8 VN1 armoured platform that is also used for a number of other applications.
The hull and turret are of all welded steel armour and provides protection from small arms fire and shell splinters.
The complete SWS2 system has a gross vehicle weight (GVW) of 23 tonnes and is operated by a crew of three consisting of commander, gunner and driver.
Mounted on the middle of the platform is a remote controlled turret, which is armed with a 35 mm revolver cannon and a pod of four SAMs. Turret traverse is 360° with gun elevation from -2° to 85° while SAM elevation is from -5° to 70°. It would appear that SAM reloads are not carried so the SWS2 will have to depend on resupply vehicles for missile replenishment.
The 35 mm revolver cannon has a maximum slant range of 4,000 m and a maximum effective height of 3,000 m with 400 rounds of ammunition being carried.
NORINCO is currently marketing a complete family of 35 mm ammunition including high-explosive incendiary (HEI), high-explosive incendiary-tracer (HEI-T), and semi-armour piercing HEI-T (SAPHEI-T) with all of these having a muzzle velocity of 1,175 m/s and fitted with a self-destruct fuze. In addition it can fire the recently developed Programmable Time Fuze Pre-fragmented (PTFP) round, which has a muzzle velocity of 1,050 m/s.
This contains more than 100 spin-stabilised tungsten sub-projectiles and is optimised to engage smaller targets such as unmanned aerial vehicles and is equivalent to the Rheinmetall Air Defence 35 mm Advanced Hit Efficient And Destruction (AHEAD) ammunition. This 35 mm ammunition can also be fired by the Chinese PG99 35 mm anti-aircraft gun (AAG), truck-mounted CS/SA1 twin 35 mm AAG, and the Rheinmetall Air Defence 35 mm KD series twin towed 35 mm AAG.
