ACE-72104 1/72 SA-9 GASKIN Mobile SA Missile System model kit
The SA-9 'Gaskin' mobile surface-to-air missile system is based on a modified BRDM-2 (4 x 4) amphibious chassis with its belly wheels removed. The original turret has been replaced by a new one-man turret with an elevating arm on either side of which are mounted two box-type launchers for the SA-9 fire-and-forget missiles. The SA-9 first entered service in 1968 and has since been widely deployed. In the CIS and some other countries it is being replaced by the SA-13 'Gopher' SAM system on a modified MT-LB chassis. The SA-9 system has a maximum range of 7000 m with altitude limits being 900 to 5000 m. It is normally deployed in batteries of four systems with one of the vehicles being fitted with the 'Flat Box A' passive radar detection system. To reduce the overall height of the system for travelling, the missiles are normally lowered into the horizontal position either side of the vehicle. No reserve missiles are carried on the SA-9 system.

The driver is seated at the front of the hull on the left with the vehicle commander to his right. Both are provided with a bullet-proof windscreen to their front which is covered by an armoured shutter, hinged at the top, when She vehicle is in combat areas. When the shutters are in position the driver and commander observe the terrain through periscopes around the front and sides of their position, mounted level with the roof of the vehicle.
The engine compartment is at the rear of the hull and there are two air-inlet louvres in the forward part of the engine compartment roof and four smaller air-inlet louvres to the rear. The exhaust pipes are on either side of the hull. The engine compartment is separated from the crew compartment by a bulkhead.
The suspension consists of four semi-elliptical springs with telescopic dual-action shock absorbers mounted two per axle. Steering is hydraulically assisted on the front two wheelswith the sealed brakes having air-assisted hydraulic actuators.
On each side of the vehicle, between the front and rear wheels, are two chain-driven belly wheels, which are lowered by the driver and give the BRDM-2 improved cross-country performance and a!so allow it to cross ditches. A central tyre pressure regulation system allows the driver to adjust the tyre pressure to suitthe type of ground being crossed. The driver can adjust the pressure on all four tyres or on individual tyres while the vehicle is still moving. If one of the tyres is damaged, the air compressor can maintain the tyre pressure until the vehicle is out of the combat area.
The BRDM-2 is fully amphibious being propelled in the water by a single water-jet at the rear of the hull. Before entering the water a trim vane which is stowed under the nose of the hull when travelling is erected at the front of the hull. When not in use the water-jet outlet is covered by a triangular plate pivoted at the top. The hydraulic control that activates both the hydrojet drive and the trim vane is located to the front of the driver. When afloat the driver uses the steering wheel as on land with the water rudders being connected to the steering wheel. At a speed of 6 to 7 km/h, its turning radius is about 10m.
The vehicle is fitted with an overpressure NBC system and its air inlet is on the top of the hull to the left rear of the turret. Standard equipment includes infra-red driving lights, an infra-red searchlight mounted over the commander's position which can be operated from within the vehicle, a winch mounted internally at the front of the hull, a radio and a TNA-2 land navigation system.
