BRDM-1 is the first purpose-built Soviet amphibious armored scout car to enter service. It was a successor of the older BA-64 and was built on the chassis and drive train of the BTR-40 armored personnel carrier. It is the world’s first mass-produced combat vehicle of its class.


The BRDM-1 primary advantage over other vehicles of that time was its amphibious capability. It was its main advantage over its direct counterpart, BTR-40. Another unique feature of the vehicle’s design was two pairs of chain-driven auxiliary wheels, which could be lowered to provide additional traction on muddy terrain.

The BRDM-1 was manufactured from 1957 to 1966 when 10,000 units entered service with the Soviet Union and its military allies worldwide. It was superseded by the improved BRDM-2, which possessed greater amphibious capabilities, a more powerful engine, and a fully enclosed turret.

BRDM-1 (4×4) was developed in the mid-1950s and entered service with the Russian Army in 1957. The later BRDM-2 (4×4) amphibious reconnaissance vehicle has replaced it in all front-line Russian units.

BRDM-1 is fully amphibious, propelled by a single waterjet mounted at the hull rear. Before entering, a trim vane is erected at the hull front, and bilge pumps switched on. On each side of the hull, between road wheels, is a set of powered belly wheels that are lowered to the ground to improve cross-country mobility. Tyre pressure regulation system is fitted as standard.

Typical armament comprises a 12.7 mm DShKM machine gun at the front and a 7.62 mm SGMB machine gun at the rear of the crew compartment.

Key recognition features

  • A pointed nose containing the engine slopes upwards towards the crew compartment, extending almost to the vehicle’s rear. Only men’s entry and exit via roof hatches.
  • Hull sides and rear are vertical, but the crew compartment’s front, sides, and rear slope inwards with two armored covers on the front and two firing ports on the sides.
  • On each side of the hull between roadwheels are two belly wheels raised when traveling on roads. Trim vane under nose when not in use.


BRDM-1 Model 1957

It had an open roof, but only a few were built.

BRDM-1 Model 1958

It was most common, with enclosed roofs and hatches.


It is a command model with four radio antennas compared with one in the standard vehicle.


It is a radiological-chemical reconnaissance vehicle with two rectangular packs at the rear for dispensing poles with pennants.
