Description
The PT-76 is a Soviet amphibious light tank designed in 1948 which saw service from 1952 up until its gradual retirement from 1967 onwards, partly replaced by the more versatile BMP-1 APC. Characterized by a wide hull and water jet propulsion, the PT-76 offered excellent amphibious capabilities. It was, however, plagued by a large silhouette, weak armor protection, and an underpowered 76 mm gun. Despite these flaws, the PT-76 enjoyed a long service life within the Soviet and Russian armed forces, which only placed it into its reserves in 2006. Comparable to other Soviet Cold War vehicles, it has seen combat in several wars and is still in use within smaller armies. Russia is attempting to replace them with BMP-3F amphibious IFVs.

Variants
PT-76A
This variant is equipped with a D-56T gun with a multi-slotted muzzle brake.
PT-76B
This version features the D-56TS gun with a double-baffle muzzle brake, fume extractor and two-axis stabilizer system. Two auxiliary fuel tanks, each with 25 gal (95 liters), were also fitted, increasing overall weight by 440 lb (200 kg). Speed is increased to 37 mph (60 kmh).
The hull was raised by 5 in (130 mm), the bow lengthened and the stern given a slightly steeper reverse angle to enhance buoyancy.
PT-76C
This variant is fitted with a 12.7-mm air defense machine gun.
PT-76(M)
NIMDA, an Israeli company, designed an upgrade package for the PT-76. This included a new Detroit Diesel 6V-92T engine developing 300 hp at 2,100 rpm coupled to the original transmission and a new clutch; a Cockerill Mk 3M-A2 90-mm main gun; and a new fire-control system with a laser rangefinder. The 90-mm barrel measures 10 ft 8 in (3.25 m).
The upgrade kit also includes a new alternator; new cooling and electrical system; and fuel, exhaust, air inlet, hull and top deck modifications.
PT-76 with AU-220M 57-mm turret
First shown in 2005 as an export-oriented upgrade, the AU-220M replaces the existing PT-76 two-man turret with the AU-220M two-man turret equipped with a 57-mm automatic gun and a 7.62-mm machine gun. The fully stabilized main gun, equipped with a muzzle brake, fires a 57 x 347 SR round. Its ammunition-handling system manages the 20 ready rounds stored in the turret and replaces them with 70 more in the vehicle.
