The PTS is a Soviet tracked amphibious transport. PTS stands for Plavayushchij Transportyer - Sryednyj or medium amphibious transport vehicle. Its industrial index was Ob'yekt 65.

Introduced in 1965,^[1] 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 somewhat higher purchase costs because it is tracked. The most common model is the improved PTS-M that is powered by a 350 hp diesel engine.

The PTS has a boxy, open watertight hull, with six road wheels per side,^[1] front drive sprocket,^[1] 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. The engine is under the floor.^[1] Propulsion in water is by means of twin propellers, in tunnels to protect them from damage during land operations.^[1]

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;^[1] the combination allows the PTS-M to accommodate an artillery tractor, field gun (up to medium caliber),^[1] its crew, and a quantity of ammunition, all in one load.^[1]

• Top speed: 40 km/h (25 mph) (road)
• Range: 300 km (190 mi)

• PTS-2
• PTS-3
• PTS-4

In 2014, the Russian Defense Ministry intends to purchase 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).^[2] Unlike its predecessors, it uses T-80 suspension components. The fully enclosed cab offers protection against small arms fire and splinter. Production began in 2014.^[3]

The PTS-M was adopted by the Soviet Army and Warsaw Pact forces,^[1] and has been supplied to Egypt,^[1] the former Yugoslavia, Iraq, Uruguay, and other nations.
