MT-LB with 14.5 mm BPU-1 turret

Also known as
  • MT-LB BPU-1
  • MT-LB with BPU-1 turret
  • MT-LB with KPVT turret
  • MT-LB with 14.5mm BPU-1 turret
  • MT-LB with BRDM-2 turret
  • MT-LB with BTR turret

The MT-LB with 14.5 mm BPU-1 turret is an improvised armored fighting vehicle that places a conical BPU-1 machine-gun turret, normally associated with BRDM-2 and BTR-family vehicles, onto the Soviet MT-LB tracked carrier. Open-source loss records document both Russian and Ukrainian examples in the 2014 Russia-Ukraine War, making the vehicle a narrow but useful example of how both sides converted available armored chassis into heavier direct-fire platforms.

Specifications

Armament
BPU-1 turret with 14.5 mm KPVT heavy machine gun and coaxial 7.62 mm PKT machine gun
Base vehicle
MT-LB tracked armored carrier and artillery tractor
Conversion type
Field or workshop conversion using existing MT-LB hulls and BPU-1/KPVT turret assemblies
Gun caliber
14.5x114 mm for the KPVT; 7.62x54 mmR for the PKT coaxial machine gun
KPVT rate of fire
About 550-600 rounds per minute cyclic for the KPVT gun
Effective range
Weaponsystems.net gives the KPV/KPVT family practical effective ranges of about 2 km against ground targets and 1.5 km against aircraft, depending on mount and sights
Mobility
Tracked MT-LB chassis; mobility varies by donor hull condition and conversion weight
Protection
Light MT-LB welded-steel armor with turret protection dependent on the salvaged BPU-1 installation
Variants

Public evidence treats the vehicle as an improvised conversion rather than a standardized production model. The key distinction is whether the fitted turret is recorded as a generic BPU-1/KPVT turret or as a donor upper hull section from a BRDM-2 or BTR-family vehicle.

Base Chassis And Gun Family

This conversion joins two already cataloged Soviet components: the MT-LB tracked carrier and the KPV/KPVT 14.5 mm machine-gun family used in the BPU-1 turret.

The conversion uses the MT-LB as the tracked base vehicle, replacing the normal light armament with a heavier turreted 14.5 mm gun installation.

The BPU-1 installation centers on the KPVT vehicle derivative of the KPV family; Weaponsystems.net identifies KPVT use on BRDM-2, BTR-60PB, BTR-70, and BTR-80 vehicles.

Why the conversion matters

The configuration gives a light tracked utility carrier heavier 14.5 mm direct-fire capability, but public evidence points to a small number of improvised vehicles rather than a standardized fleet.

Conversion Pattern

The sourced record points to a practical battlefield adaptation: crews or workshops reused available BPU-1 turret assemblies from BRDM-2 or BTR-family vehicles and mounted them on MT-LB hulls. That changed the MT-LB from a light carrier and tractor into a heavier machine-gun fire-support vehicle, while retaining the base chassis' light armor and tracked mobility.

Turret fit

Army Guide identifies the BPU-1 mount as carrying a 14.5 mm KPVT, a 7.62 mm PKT, and smoke grenade equipment in BTR-80-style installations.

Public reporting shows the concept emerging in 2022 with Ukrainian Kraken and Territorial Defense-linked examples, trading the towed gun's normal setup time for a more mobile direct-fire and support-fire platform with limited crew protection.

Its higher hull, longer seven-road-wheel chassis, and 300 hp YaMZ diesel engine gave armies more internal volume and payload margin for command posts, artillery fire-control vehicles, radar carriers, electronic-warfare systems, and later battlefield conversions in conflicts such as the 2014 Russia-Ukraine War.

Designed to move infantry and light weapons across rivers and broken terrain, it carried a small crew plus a large troop compartment behind light welded steel armor. Its record spans Arab-Israeli wars, the Iran-Iraq War, Syria, and Russia's Ukraine deployment of stored vehicles, including photographed and loss-documented BTR-50PK carriers fitted with BPU-1 turrets.

Open-source reporting and Russian loss documentation tie the conversion to the full-scale 2014 Russia-Ukraine War, where it appears as a short-range air-defense and direct-fire adaptation rather than a standardized factory combat vehicle.
