The BMD-4 airborne combat vehicle entered service with Russian airborne units in 2005. This vehicle uses the BMD-3 chassis, but carries a significantly more powerful armament. In some cases the BMD-4 can replace main battle tanks and artillery units with its firepower during landing operations. Some older BMD-3 are being upgraded to BMD-4, while a low-rate production of new vehicles continues.

Armor of this airborne combat vehicle provides protection against small arms fire and artillery shell splinters. The BMD-4 is fitted with NBC protection and automatic fire suppression systems.

Vehicle has a crew of three, including commander, gunner and driver. It provides accommodation for five fully equipped troops.

The BMD-4 is powered by the 2V-06-2 diesel engine, developing 450 hp. Vehicle can be paradropped with all the crew inside, thus saving time for the assembly after landing. Furthermore it is well suited for amphibious landing operations. The BMD-4 is fully amphibious and can fire all its weapons afloat at sea worthiness 2. On water it is propelled by two waterjets.

The new IFV features more spacious hull compared to its predecessor. The manned compartment accommodates up to two crew and six infantrymen. The driver is seated in the front and the engine is placed at the rear part of the hull.

A satellite navigation system is incorporated to provide geographic location details. The vehicle also features a digital computer control system.

Armament and protection of BMD-4M IFV

The airborne assault vehicle is armed with a 100mm 2A70 semi-automatic gun / missile launcher weighing 332kg.

The 100mm gun uses an automatic loader with 34 rounds of 100mm ready to fire and 18 in reserve. The main gun can fire conventional types of ammunitions and also the 100mm laser-guided ammunition Arkan Tandem 9M117M1 which can be used against modern main battle tanks at a maximum range of 5,500m and against sheltered and exposed personnel and fortifications at a maximum range of 7,000m.

The 2A70 gun is coupled to a highly reliable 30mm 2A72 automatic cannon mounted on the turret. It can fire GSh-6-30 rounds with a muzzle velocity of 960m/s. The rate of fire is more than 300 rounds per minute. The launcher can fire either 3UOF17 or 3UOF19 rounds at a rate of ten rounds a minute. Its muzzle velocity ranges from 250m/s to 355m/s.

30mm 2A72 automatic cannon

30mm 2A72 automatic cannon
 The 2A72 is a late Cold War era 30mm autocannon of Soviet origin. It was developed as a less complex and lighter alternative to the widely used 2A42. Studies revealed that the 2A42 was virtually always used at the low rate of fire setting. By modifying and simplifying the 2A42 design it could be produced at lower cost and be used for a wider range of applications. The 2A72 is used both as main armament and as a coaxial weapon for the 100mm 2A70 low pressure cannon.
The 2A72 is a much simplified design based on the 2A42 consisting of only 349 parts instead of 578. Unlike the 2A42 it is not gas operated but recoil operated. A new design muzzle brake is used in order to retain enough recoil to cycle the weapon.
The 2A72 fires the common 30x165mm round of which several types are available. The rate of fire is 330 rpm which is effectively similar to the earlier 2A42 that was hardly used at the higher rate of fire setting. The effective range is 1.5 km versus armored vehicles. The effective range for the high explosive rounds is about 2 km versus infantry, vehicles and aircraft although it has a slant range of 4 km.

30 x 165mm round

2A72 cannon is a part of armament system of Russian highly advanced BMP-3 IFV, as well as a part of armament system of the KLIVER turret, designed for mounting on the old-design IFVs and APCs.

2A38 cannon is a part of armament system of self propelled, advanced AD gun/missile weapon systems 2S6/2S6M TUNGUSKA and PANTSYR-S1.

These weapon/ammunition systems are capable of engaging the following targets:

  • Low-flying aerial targets (fixed and rotary wing aircraft, UAV’s, cruise missiles, stand-off weapons )
  • Lightly armoured targets (APC’s, IFV’s)
  • Wide range of ground targets – field fortifications, dismounted infantry etc.
  • Wide range of targets in urban warfare

Basic features:

  • Advanced propellant charge design, providing for high ballistic performances of the projectile, low weight and small dimensions of the cartridge case, as well as for small cannon dimensions and weight and high weapon system ammunition capacity.
  • Highly reliable mechanical gun primer
  • Advanced steel cartridge case manufacturing technology, providing for high mechanical stress resistance and extremely high rate of fire weapon capabilities
  • Modern HE projectile design, providing extremely high interior and exterior ballistic performance and terminal efficiency against wide range of aerial and ground targets
  • Highly effective explosive charge ( RDX or RDX / Al mixture )
  • Effective range against aerial targets at more than 3000 m
  • Effective range against ground targets at more than 4000 m
  • Advanced impact fuzes with highly reliable self-destruction device
  • Highly reliable tracers with long burning time, enabling visual control of projectile’s flight
  • High flexibility of tactical use
  • Target practice/target practice with tracer rounds for training purposes

Fire control

The weapon system is integrated with an improved fire control equipment to provide the IFV with the ability to track and engage the targets while on the move. The fire control system incorporates a gunner’s sight to identify the targets during both day and night, a commander’s panoramic TV-aimed sight and an automatic target tracker.

Unobserved threats, antitank weapon and other small targets, fixed-wing and rotary-aircraft can be engaged at a maximum range of up to 4,000m. A total of eight Arkan ammunitions are carried, with four ready to use and four in reserve. Three smoke grenade dischargers are mounted to each side front of the turret. The BMD-4M can fire at day and night, while the vehicle is on the move, stationary or afloat. The weapon station is equipped with an advanced computerized fire control system including a combined day/night gunner’s sight, a commander’s panoramic TV-aimed sight, a digital computer, an automatic target tracker and automatic devices which supply data on unobserved targets.  @thesovietarmourblog.blogspot.com

Engine and mobility

The BMD-4M is powered by a multi-fuel, type UTD-29 diesel engine that produces a power of 500hp.

See details of  Il-76 cargo aircraft: HERE

The Il-76 cargo aircraft can carry two of these ACVs.

The engine, with a power of 500 horsepower, allows the machine to reach speeds up to 65 kilometers per hour. In addition, BMD-4M is able to force a serious water obstacles, literally swimming across them. The speed of the machine can reach 10 miles per hour. Without refueling the BMD-4M can cover a distance of up to five hundred kilometers. This allows her to fight for several hours as breaking through the line of defense and retreat, if the need arises. The BMD-4M is the world’s only machine that can be parachuted together with the crew – and right into the fray.

As the previous vehicle, the modernized BMD-4 is adapted to make parachute landing from airplane of transport aviation together with the crew, and also to moving over the water and ground. The BMP-4M is to Spawn a range of derivatives for use by the Army and other uniformed services. This will both enable Kurganmashzavod and VgTZ to step up their output and expand their export capabilities. Power plant installation, running gear and the chassis control system with plants unified with systems of BMP-3 allowed to increase the following functional characteristics of modernized vehicle:

  • Maneuverability: cause of increasing the average traveling speed (the power of engine is 50 h.p. more)
  • Cross-country ability is better, because of the lowering specific ground pressure by the increasing of track undersurface length.
  • Reliability of PPC and running gears units (road wheels, tracks).
  • Volumetric capacity: the crew is increased from 7 to 8 men in the manned compartment because of the great compactness of the power plant compartment.
  • Controllability is better because of the usage of chassis digital informative-processing system.
  • Fire power: the fighting compartment with improved fire control system, digital control system and satellite navigation were set at the vehicle.
  • Buoyancy: the rear part of the vehicle is made without space above power pack, which increases inside volume of hull and reserve vehicle buoyancy (up to 41,5%), and different on buoyancy is not more than 2… 3º.
  • Ergonomy: convenient come in/out through the rear hatch for the crew, that is sitting near the bulkhead, and the possibility to leave the vehicle through the hatches on the roof (above the draught-line) without pouring water inside. 

By 2013 a total of 123 BMD-3 and 60 BMD-4 airborne combat vehicles were in service with the Russian Airborne Troops, with the rest being outdated BMD-2 models. The Russian military expected to acquire at least 1,000 BMD-4Ms under the current rearmament program until 2020.

The Russian Defense Ministry is to receive more than 250 airborne troops’ combat vehicles BMD-4M and armored personnel carriers BTR-MDM Rakushka over three years to come under a contract with the Tractor Plants concern, its first vice-president and co-owner, Albert Bakov told TASS 13 May 2015. “We have a three-year contract with the Defense Ministry for providing BMD-4M and BTR-MDM. More than 250 vehicles are to be delivered to the airborne troops,” Bakov said.

According to earlier reports, the first batch of the new vehicles was provided in early March 2015. Then it was expected that Russia’s paratroop units would receive a total of 62 BMD-4M and 22 BTR Rakushka by the end of the year. Source thesovietarmourblog.blogspot.com
