Amphibious armoured scout car (1957)
Soviet Union - 10,000 built

A strange amphibious 4x4/8x8

BRDM-1 Obr.1957
The previous BTR-40 light APC was used as a reconnaissance vehicle in the 1950s, but was severely limited in its mobility by its lack of amphibious capabilities, something that did not exist with prior Soviet wheeled vehicles but was made imperative in the new planned tactics based on speed. Eventually, Soviet engineers as often came with an out-of-the box solution. More than converting a BTR-40 to be amphibious, they built a boat-shaped hull with a convertible wheeltrain, 4x4 or 8x8 to increase mobility of the worst soft grounds like swamps, sand, deep mud, creating a truly all-terrain vehicle. Built by ten of thousands, it was exported to the Warsaw Pact countries, built under licence, and fifty countries adopted it worldwide.


Late 1954 work began at the A. Dedkov OKB design bureau, under the direction of designer V. K. Rubtsov. The first drawings were an amphibious variant of the BTR-40 designated BTR-40P, but as the design progressed it changed to a true amphibious armored scout car, or "Boyevaya Razvedyvatelnaya Dozornaya Mashina" which gave BRDM. This designation was changed to BRDM-1 when a brand new model came out in 1962. The BRDM first prototype came out in February 1956, was heavily tested on the black sea, and approved for service in 1957. Production started the same year and ended in 1966 after 10,000 vehicles had been cranked-up with gradual upgrades.



The hull was made in welded steel RHA, made completely waterproof and has a distinctive boat-shape, especially at the front. The hull was only 10 mm at the thickest (at the front), however, the nose had the extra protection of the trim vane, stored in neutral position. The engine was mounted at the front, and crew compartment relegated to the rear, which gave this "long nose", ducky appearance. In the driving compartment, the driver sat on the left, and commander at the right, both with their own armored shutters with integral vision blocks instead of simple slits. There was no IR device but the driver was assisted by driving lights, and a single white light searchlight. At first, the BRDM obr.1957 was given an open roof, but rapidly on the obr.1958, it was enclosed, with hatches above the driver and commander seats while two more were added at the rear slope when the roof joined the hull. The rest of the crew took place behind. he commander operated the main armament, generally placed in a centrally-mounted pintle mount between at the front. They were pistol ports in the superstructure sides (four), and one in each rear hatch. However, the vehicle was not NBC protected.


The Major Innovation of the design came from its unique convertible 4x4/8x8 configuration. The normal stand was 4x4, with fixed axles, but two axles took place in between, belly wheels which can be lowered to improve cross-country performance and ease ground pressure. On road, they were always in raised position. The BRDM was propelled by a GAZ-40PB V8 in-line gasoline giving 90 hp (70 kW) at 3,400 rpm, for a power to weight of 16 hp/tonne (12.4 kW/tonne). This engine was derived from a ww2 US-built Dodge truck engine and was connected to a manual gearbox, single dry-plate clutch, with four forward gears and one reverse. This vehicle was really optimized to be amphibious, being given a front trim vane which, when erected deflected waves, and a rear water jet on the hull's back panel. The jet is produced by an internal four-bladed propeller driven by the engine. its outlet is protected armored shutter while traveling on land.


Normal, standard armament was the pintle-mounted central 7.62 mm SGMB medium machine gun which only appeared with the Obr.1959. Both previous models (1957, and 1958) were completely unarmed. Tow optional 7.62 mm SGMB medium machine guns could be mounted on the side pintle mounts from the Obr.1960. and even three on the late models. From the Obr.1961, the central SGMB was replaced by a heavy 12.7 mm DShK 1938/46 and even later, or optionally by the new 14.5 mm KPV heavy machine gun. So some models were armed with up to four MGs, a central KPV, rear pintle-mounted SGMB and two others on the sides, plus the pistol ports weapons.



NBC reconnaissance vehicle: Two KZO-2 flag dispensers, several detection devices (DP dosimeter, PCHR-54 semi-automatic detection), also designated BTR-40P-Rkh.


Command version: Additional R-112 radios and 3 whip antennas, also designated BTR-40PU. A sub-variant has a rear traffic light.


Tank Destroyer (1958): 2K16 launcher for three 3M6 "Shmel" (AT-1 Snapper) ATGM launchers. The whole compartment was rebuilt and rear seats eliminated to make room for the raising launcher, which could traverse 360°. It is normally hidden inside of the superstructure, making it impossible to distinguish from the standard BRDM.


Tank Destroyer (1962), similar, but upgraded to the 2K8 launcher with four bigger 9M11 "Falanga" (AT-2 Swatter).


Tank Destroyer (1963), armed with the smaller 9M14 "Malyutka" (AT-3 Sagger). Six could be carried on the 9К14М launcher. The launching apparatus was simplified and there was no overhead protection for the operator.

The BRDM-1 in action

It entered service in 1957 and was produced until 1966 when replaced by the BRDM-2. Czechoslovakia only used the BRDM-1 obr. 1958 before swapping to the OT-65, local denomination of the Hungarian D-442 FÚG, and the BRDM-2. Hungary devised soon its own vehicle. Poland was the most prolific user, with more than 800 vehicles, including the 2P27 and 9P110 tank hunters, and BRDM-RKh in recce units before being replaced by their BRDM-2 equivalents in the 1970s. Egyptian and Syrian vehicles saw action in the Yom Kippur war (1973), Iraqi vehicles during the Iran-Iraq war and 1st gulf war. Angolan vehicles participated in the 1980s "Bush war", and many others were found in military actions in minor conflicts and civil wars. An estimated 600 vehicles are still in service worldwide, mostly in Africa, most being second-hand, ex-Soviet vehicles replaced by the BRDM-2. Although its mobility was excellent, poor protection was really a problem, as any heavy machine gun could destroy it with ease. It was also found vulnerable to mines. Its others limitations were exposed gunners, no NBC protection, no default vision equipment nor special sight. It was quite primitive for recce missions, only relying on its mobility. The BRDM-2 solved these problems and was equally successful on the export market.

They go hand in hand.

Tanks had no tactical manual when first used. It was learned the hard way and perfected over decades, as well as weapons, countermeasures and accompanying vehicles.
