BMP-1 Infantry Fighting Vehicle (IFV)

The BMP-1 is the first mass-produced infantry fighting vehicle (IFV) of the SSSR. It is tracked vehicle which has full amphibious capability. One of its most important features is a front-engined chassis developed especially for it, a welded steel hull with a sharp, sloping front with a conspicuously ridged surface, and a centrally located, flat, truncated cone turret with a troop compartment at the rear.

Introduction

BMP-1 is an Infantry Fighting Vehicle (IFV) developed in the early 1960s to replace BTR-50P series tracked APCs and was first seen in public in 1967. It was replaced in production by BMP-2 ICV, which, although similar in appearance, has a slightly different layout and new turret and weapon system. The latter followed BMP-3.

Design

In the BMP-1, the driver sits front left with the vehicle commander to the rear, and the engine compartment is to the right of the driver with a one-man turret center and troop compartment rear. Turret power traverses through 360 degrees, and a 73mm gun elevates from -4 degrees to +33 degrees and fires HEAT or HE-FRAG rounds. 7.62mm machine gun is mounted coaxial to the right of the 73m gun, and mounted over the gun is the launcher for AT-3 Sagger wire-guided ATGW, which has a maximum range of 3,000m.

The troop compartment is at the rear with eight infantry seated, four on each side, back to back. On each side of the troop compartment are four firing ports with a periscope above and in each of the two rear doors is a further firing port and periscope.

BMP-1 is fully amphibious, propelled by its tracks. Before entering the water, a trim vane is erected in front of the vehicle, and bilge pumps are switched on. As BMP-1 was produced for some 20 years, there are minor detailed differences between production models.

Key recognition-features

Pointed nose with almost horizontal ribbed glacis plate, driver front left, engine compartment louvers in the roof to the right, turret slightly to the rear of the vehicle, troop compartment rear with four roof hatches, two on each side. Vertical hull rear with two bulged doors opening rear. Similar in appearance to BMP-2 but with a different turret with a long-barreled 30mm cannon and a wider hull

A circular turret with well-sloped sides has a 73mm gun with a launcher above for Sagger ATGW (not always installed in peacetime) single gunner’s hatch on the left side of the roof. Four firing ports on each side of the hull and three on each rear door

Suspension on each side has six road wheels, a drive sprocket at the front, an idler rear, and three track-return rollers—the upper part of the track is covered by skirts.

Status

The vehicle was in service with Afghanistan, Algeria, Angola, Bulgaria, Russia, Cuba, Egypt, Ethiopia, Finland, Greece, Hungary, India, Iran, Iraq, North Korea, Libya, Mongolia, Poland, Romania, Sri Lanka, Sweden, Syria, Yemen, and former Yugoslavia.

Today, a dozen countries are still using it, but the major countries with more than 1,000 units in active service are Russia, India, Poland, and the People’s Republic of China.

Conflicts

The BMP-1 was first tested in combat in the 1973 Yom Kippur War, where Egyptian and Syrian forces used it. Based on lessons learned from this conflict and early experiences in the Soviet-Afghan War, a version with improved fighting qualities was developed, the BMP-2 and BMP-3, that followed later.

Syrian Civil War

It was used widely in the Syrian civil war, first by Syrian government forces and later with almost all factions owning some of the vehicles. It was also used as VBIED (vehicle-borne improvised explosive devices) in suicide attacks. The vehicle’s advantages in this role are the large capacity of explosives it can carry, the off-road capability afforded by tracks, and the armor that both protects the driver from fire and amplifies the effect of the explosion.

Ukraine War

During Ukraine War, Ukrainian Armed Forces had dozens of those IFVs at their disposal. At the beginning of April, Germany announced that it would send a total of 56 those IFVs to Ukraine to support its defense against the Russian invasion. Most of them had previously been in service in Eastern Germany.

Former Czechoslovak and Russian state’s arsenals. China has its version of this IFV designated as WZ 501.
