The PT-76 ( Russian ПТ-76, плавающий танк , p lawajuschtschi t ank or Object 740 ) is a light floating tank that was introduced in the Soviet Army in 1952 ; Licenses and replicas were made in China and Czechoslovakia . The PT-76 was delivered to over 25 countries and mainly used in reconnaissance units. It was also part of the original equipment of the East German NVA .
description
PT-76
His strengths in terms of swimming without preparation, speed and agility contrasted with a number of weaknesses. To reduce weight, the PT-76 had only weak armor and light armament with limited vertical swivel range - to limit the vehicle height. Neither night vision equipment nor NBC protection were intended for the model. The main armament was a 76 mm D-56T cannon with a maximum rate of 15 rounds per minute with an ammunition supply of 40 shells. A 7.62 mm MG SGMT was installed parallel to the axis. Both weapons could be used during the water journey. The 14-ton tank was powered by a 240-horsepower W-6 diesel engine (practically a W-2 engine cut in half ), which reached 45 km / h. The drive of the PT-76 was a torsion bar sprung roller drive with six one-piece rollers on each side. The drive wheels were at the stern, the idlers at the front of the vehicle. The crawler belt was a link chain with two guide teeth between which the rollers ran.
In the water, two water jet drives were switched on, with which 10 km / h could be achieved. There is a flip-up surge board at the bow of the tank .
The crew consisted of three soldiers.
The PT-76 was continuously modernized, so the cannon was replaced by the modified D-56TM, which had an active-reactive muzzle brake and a smoke extractor in the middle of the barrel . A modernized radio equipment was installed and the tank was equipped with the TDA night vision device.
PT-76M
Prototype of an improvement from 1950 (Object 740M) for the Soviet marine infantry : greater water displacement, night vision device, NBC protection, engine W-6M with 300 hp. Cannon D-56TS with 2-plane stabilizer STP-2P "Sarja". The vehicle was never mass-produced and the Marines received regular PT-76Bs that could be equipped with snorkels in its place .
PT-76B
The PT-76B (Object 740B) produced from 1958 corresponded to the previous model. Parts of the combat value increase from the PT-76M were implemented. It was equipped with the stabilized D-56TS cannon (2-level stabilizer STP-2P "Sarja"), which was more accurate. As a result of the improved weapon system, the tower was around 15 cm higher at 2.32 meters and the total weight increased by 200 kg to 14.2 tons. The W-6 engine with 240 hp was retained. Furthermore, the PT-76B was equipped with a nuclear weapon protection system and an additional internal tank, and improved electronics were installed. Part of the PT-76B received launch equipment for the PALR 9M14 "Maljutka" on the rear of the tower.
Others
The PT-76 drive served as the basis for various other tracked armored vehicles. Among other things for the SPw 50P , -PK and -PU; for the tactical rocket launch pads 2K1 Mars and 2K6 Luna it was modified with support rollers.
A derivative with reinforced armament is the Chinese Type 63 and Type 63A .
The turret of the PT-76B was in 1967 for the gunboats of the project in 1204 used.
