Introduced in 1965, it is large, with a substantial payload of 10 tons, two to four times the capacity of the BAV 485, and better cross-country performance, at the cost of greater somewhat higher purchase costs because its tracked. The most common model is the improved PTS-M that is powered by a 350 hp diesel engine.
It resembles its antecedents, the BAV 485 and ultimately DUKW, having a boxy, open watertight hull, with six road wheels per side, front drive sprocket, rear idler sprocket, and no return rollers. Like the BAV 485, and unlike the DUKW, it has a rear loading ramp. The crew is seated at the front, leaving the rear of the vehicle open for a vehicle, which can be driven (or backed) in, rather than lifted over the side (as in the DUKW). To aid in facilitating this, the engine is under the floor.
The PTS-M also has a companion vehicle, the PKP, a boat-like amphibious two-wheeled trailer, with fold-out sponsons providing stability on water; the combination allows the PTS-M to accommodate an artillery tractor, field gun (up to medium caliber), its crew, and a quantity of ammunition, all in one load.
In 2014, the Russian Defense Ministry intends to purches an undetermined number of PTS-4s, which underwent acceptance trials in 2011. The vehicle will be fitted with a remotely-operated 12.7 mm (0.50 in) machine gun and a multi-fuel engine. The PTS-4 weighs 33 tons, with a payload of 12 tons on land (18 tons on water). Projected maximum road speed is 60 km/h (37 mph), with an expected maximum speed in water of 15 km/h (9.3 mph). Unlike its predecessors, it uses T-80 suspension components. The fully enclosed cab offers protection against small arms fire and splinter. Production is expected to begin in 2014.
