The MT-LB (Russian: Многоцелевой Тягач Легкий Бронированный, romanized: Mnogotselevoy tyagach legky bronirovanny, literally "multi-purpose towing vehicle light armored") is a Soviet multi-purpose, fully amphibious, tracked armored fighting vehicle in use since the 1970s. It was also produced in Poland, where (starting in the mid-1990s) its YaMZ engine was replaced by a Polish 6-cylinder SW 680 diesel engine.^[2]

In the 1950s, the Soviet Central Auto and Tractor Directorate began a development program to replace the AT-P series of artillery tractors (which were based on the ASU-57 airborne self-propelled gun) with a new generation of vehicles. The MT-L was developed to meet this requirement based on the PT-76 amphibious light tank chassis. The MT-LB is the armored variant of the MT-L. Entering production in the early 1970s, it was cheap to build, being based on many existing components, e.g. the engine, which was originally developed for trucks.

It was built at the Kharkiv Tractor Plant^[3] (KhTZ) in Soviet Ukraine, and in Bulgaria.^[4][5] Formerly it was also manufactured under license in Poland by Huta Stalowa Wola^[6]

The crew (a driver and a commander/gunner) sit in a compartment at the front of the vehicle, with the engine behind them. A compartment at the rear enables up to 11 infantry to be carried or a cargo of up to 2,000 kilograms (4,400 lb). A load of 6,500 kilograms (14,300 lb) can be towed. The vehicle is fully amphibious, being propelled by its tracks in the water.^[7]

A small turret at the front of the vehicle fits a 7.62 mm PKT machine gun with 360-degree manual traverse and an elevation of −5 to +30 degrees. The vehicle is lightly armored against small arms and shell splinters with a thickness of three to ten millimetres (0.12 to 0.39 in) of steel with a maximum of 14 millimetres (0.55 in) for the turret front.^[8]

Several weapon systems are based on this hull (for example Strela-10 or SNAR-10).

  • MT-LB (izdeliye 6) – basic model, often used as simple APC but also as artillery tractor or ambulance. In the West the term MT-LB Blade or MT-LB M1980 is used for vehicles that are fitted with a hydraulic dozer blade.^{[citation needed]}

• Bulgaria has various models of the MT-LB in service, as of 2016.^[9] Along with the base model, between 1971 and 2012 Bulgaria manufactures MT-LB VM variation with improved snow and swamp-going capabilities.^[10][11]

• MT-LB (BO) SFL – battery command vehicle in self-propelled artillery units.
• San MT-LB – ambulance
• MTP-LB – technical support vehicle.

• MT-LB converted into a SPAAG by mounting a ZU-23-2 23×152mm twin anti-aircraft gun on the rear part of the vehicle. The gun had its wheels removed and as such cannot be easily dismounted and used separately. There were at least two variations of this conversion; one with the ZU-23-2 mounted in an open-topped turret, the other with the ZU-23-2 mounted on a platform extending beyond the hull of the MT-LB with a roof for the gun operators. The second version was most likely intended to be used in a fire support role, as the roof would hinder the gun's sights at high elevation.^[13]

Polish HSW S.A. (Huta Stalowa Wola S.A.) license produced MT-LB since 1976, and it also developed a modified chassis SPG-2, with better floating capabilities.^[14]
