BMP development

From Wikipedia, in a visual modern way
BMP-1
BMP-1

The BMP series were among the first production line infantry fighting vehicles. Included in the series are the mainline BMPs, the airborne variant BMDs, and licensed modified (i.e. MLI-84) and reverse engineered versions (i.e. Boragh, Type 86). BMP stands for Boyevaya Mashina Pekhoty (Russian: Боевая Машина Пехоты), meaning "infantry fighting vehicle".[1] They were initially developed in the 1960s in the Soviet Union.

Infantry fighting vehicle

Infantry fighting vehicle

An infantry fighting vehicle (IFV), also known as a mechanized infantry combat vehicle (MICV), is a type of armoured fighting vehicle used to carry infantry into battle and provide direct-fire support. The 1990 Treaty on Conventional Armed Forces in Europe defines an infantry fighting vehicle as "an armoured combat vehicle which is designed and equipped primarily to transport a combat infantry squad, and which is armed with an integral or organic cannon of at least 20 millimeters calibre and sometimes an antitank missile launcher". IFVs often serve both as the principal weapons system and as the mode of transport for a mechanized infantry unit.

Airborne forces

Airborne forces

Airborne forces are ground combat units carried by aircraft and airdropped into battle zones, typically by parachute drop or air assault. Parachute-qualified infantry and support personnel serving in airborne units are also known as paratroopers.

MLI-84

MLI-84

The MLI-84 is a tracked Romanian infantry fighting vehicle currently in service with the Romanian Land Forces. It was derived from the chassis of the Soviet BMP-1 but possessing a lengthened hull, a 12.7×108mm DShK 1938/46 heavy machine gun mounted on the roof of the troop compartment and MLI-84M having Oerlikon KBA autocannon and new ATGMs.

Boragh

Boragh

Boragh or Boraq is an Iranian-made armoured personnel carrier. Boragh is believed to be a reverse engineered and upgraded model of the Chinese Type 86 (BMP-1). The upgrades include a reduction in weight, a higher road speed, and stronger armor. The vehicle is fully amphibious and is fitted with an NBC protection system and infra-red night vision equipment.

Russian language

Russian language

Russian is an East Slavic language mainly spoken in Russia. It is the native language of the Russians and belongs to the Indo-European language family. It is one of four living East Slavic languages, and is also a part of the larger Balto-Slavic languages. Besides Russia itself, Russian is an official language in Belarus, Kazakhstan, and Kyrgyzstan, and is used widely as a lingua franca throughout Ukraine, the Caucasus, Central Asia, and to some extent in the Baltic states. It was the de facto language of the former Soviet Union.

Soviet Union

Soviet Union

The Soviet Union, officially the Union of Soviet Socialist Republics (USSR), was a transcontinental country that spanned much of Eurasia from 1922 to 1991. A flagship communist state, it was nominally a federal union of fifteen national republics; in practice, both its government and its economy were highly centralized until its final years. It was a one-party state governed by the Communist Party of the Soviet Union, with the city of Moscow serving as its capital as well as that of its largest and most populous republic: the Russian SFSR. Other major cities included Leningrad, Kiev, Minsk, Tashkent, Alma-Ata, and Novosibirsk. It was the largest country in the world, covering over 22,402,200 square kilometres (8,649,500 sq mi) and spanning eleven time zones.

Background

Priest Kangaroo armored personnel carrier, 1945.
Priest Kangaroo armored personnel carrier, 1945.

World War II began with the concepts of armored warfare relatively undeveloped, particularly the use of combined arms teams. Tank and infantry units were often organized as separate units, which led to problems of command and coordination.

As the war progressed the doctrine of combined arms became better refined, and the need for specialist vehicles to keep the infantry in close contact with the armor became increasingly important. Most of these vehicles were half-tracks. There were expedient measures; the infantry of the Red Army often rode on the top of tanks. In 1944 the Canadians introduced the practice of converting self-propelled guns and tanks to carry infantry - known as "Kangaroos". The Kangaroo pointed the way forward, offering much better armor than half-tracks and able to keep up with the tanks on any terrain.

In the post-war era most armies started introducing fully tracked vehicles in the dedicated armored personnel carrier role, including the Soviet BTR-50, British FV432, and the US M113. These vehicles generally suffered in terms of range and speed, and many forces also adopted wheeled vehicles in addition to, or instead of the tracked versions. In general, these vehicles offered limited protection and were not expected to join in the actual fighting; they would keep the infantry in close proximity with the armor during movement, but upon enemy contact they would unload their infantry before retreating to safer areas - a practice that led to them being called "battlefield taxis" or "battle-taxis". The German Schützenpanzer Lang HS.30 was an exception as it carried a 20mm cannon for support of its infantry and against light vehicles.

During the 1950s this mode of combat was increasingly questioned. Unloading the infantry onto a battlefield that was assumed to be littered with chemical and nuclear poisons did not seem like a good idea. Further, while the APCs moved to and from combat the infantry section in the back had nothing to do, a claustrophobic environment where the men could not add to the fight. Military theorists turned to the concept of the infantry fighting vehicle (IFV), similar to the APC but with the expectation that the infantry section would be able to stay in the vehicle and fight effectively, while also improving the vehicles own armament. The Soviets were the second to adapt to this new style of fully mechanized combat, issuing requirements and then introducing the BMP in mid-1960s, following after the more limited scale Western German Panzergrenadier deployment of the HS.30.

Kangaroo (armoured personnel carrier)

Kangaroo (armoured personnel carrier)

A Kangaroo was a Canadian armoured personnel carrier (APC) during the Second World War which was created by converting a tank chassis. Kangaroos were created as an expedient measure "in the field" by the Canadian Army, and were so successful that they were used by other Commonwealth forces, including the British Army.

World War II

World War II

World War II or the Second World War, often abbreviated as WWII or WW2, was a global conflict that lasted from 1939 to 1945. The vast majority of the world's countries, including all of the great powers, fought as part of two opposing military alliances: the Allies and the Axis. Many participants threw their economic, industrial, and scientific capabilities behind this total war, blurring the distinction between civilian and military resources. Aircraft played a major role, enabling the strategic bombing of population centres and the delivery of the only two nuclear weapons ever used in war.

Combined arms

Combined arms

Combined arms is an approach to warfare that seeks to integrate different combat arms of a military to achieve mutually complementary effects—for example, using infantry and armour in an urban environment in which each supports the other).

Half-track

Half-track

A half-track is a civilian or military vehicle with regular wheels at the front for steering and continuous tracks at the back to propel the vehicle and carry most of the load. The purpose of this combination is to produce a vehicle with the cross-country capabilities of a tank and the handling of a wheeled vehicle.

Tank desant

Tank desant

Tank desant is a military combined arms tactic, where infantry soldiers ride into an attack on tanks, then dismount to fight on foot in the final phase of the assault. Note that this differs from infantry troops merely riding on tanks as a form of ad-hoc transportation. Desant is a pan-Slavic general term for airborne or parachute drops and naval infantry amphibious landing operations.

BTR-50

BTR-50

The BTR-50 is a Soviet tracked amphibious armored personnel carrier (APC) based on the PT-76 light tank chassis. The BTR-50 was developed in 1952 and entered service with the Soviet Army in 1954. It ceased production in 1970. It has the ability to transport up to 20 fully equipped infantrymen, and can be armed with nothing, a 7.62 mm SGMB medium machine gun, or a 14.5 mm KPV heavy machine gun. It saw notable service in the Six-Day War, the Yom Kippur War, and most recently in the Russo-Ukrainian War.

FV432

FV432

The FV432 is the armoured personnel carrier variant in the British Army's FV430 series of armoured fighting vehicles. Since its introduction in the 1960s, it has been the most common variant, being used for transporting infantry on the battlefield. At its peak in the 1980s, almost 2,500 vehicles were in use.

M113 armored personnel carrier

M113 armored personnel carrier

The M113 is a fully tracked armored personnel carrier (APC) that was developed and produced by the FMC Corporation. The M113 was sent to United States Army Europe in 1961 to replace the mechanized infantry's M59 APCs. The M113 was first used in combat in April 1962 after the United States provided the South Vietnamese Army (ARVN) with heavy weaponry such as the M113, under the Military Assistance Command, Vietnam (MACV) program. Eventually, the M113 was the most widely used armored vehicle of the U.S. Army in the Vietnam War and was used to break through heavy thickets in the midst of the jungle to attack and overrun enemy positions. It was largely known as an "APC" or an "ACAV" by the allied forces.

Schützenpanzer Lang HS.30

Schützenpanzer Lang HS.30

Schützenpanzer Lang HS.30, formally Schützenpanzer, lang, Typ 12-3, or SPz lg 12-3 for short, was a West German infantry fighting vehicle developed from 1956 to 1958. It was a Swiss Hispano-Suiza design, with a Rolls-Royce engine. After some early mechanical problems, only 2,176 were built of the 10,680 planned. It was armed with a powerful 20 mm autocannon, a common choice for infantry fighting vehicles of the period.

BMP-1

BMP-1

The BMP-1 is a Soviet amphibious tracked infantry fighting vehicle, in service 1966–present. BMP stands for Boyevaya Mashina Pyekhoty 1, meaning "infantry fighting vehicle, 1st serial model". The BMP-1 was the first mass-produced infantry fighting vehicle (IFV) of the Soviet Union. It was called the M-1967, BMP and BMP-76PB by NATO before its correct designation was known.

Requirements

The requirement for the BMP was first drawn up in the late 1950s. The requirement stressed speed, good armament, and the ability for all squad members to fire from within the vehicle. The armament had to provide direct support for dismounted infantry in the attack and defense and to be able to destroy comparable light armored vehicles such as the American M59 APC or the West German HS.30 IFV.[2]

The armor was required to protect the crew and passengers from light shell fragments as well as .50 cal armor-piercing bullets and 20–23 mm caliber autocannons across the frontal arc at distances between 500 m and 800 m (the distance of infantrymen dismounting onto the battlefield during an attack). Side armor should be capable of withstanding 7.62 mm armor-piercing bullets from a distance of 75 m. The requirements also included an NBC protection system, observation devices similar to those used in MBTs and a radio capable of communicating with unit commanders and tanks.

The original specification called for the vehicle to be armed with a 23 millimetres (0.91 in) autocannon,[2] however an innovative combination of the 73 mm 2A28 Grom low pressure smoothbore semi-automatic gun firing rocket-assisted projectiles and the newly developed 9S428 anti tank wire guided missile (ATGM) launcher for the selected 9M14 "Malyutka" (AT-3A Sagger A) ATGMs was used instead. The gun was intended to engage enemy armored vehicles and firing points at a range of up to 1,300 metres (1,400 yd), while the missile launcher was intended to be used against targets that were 500 metres (550 yd) to 3,000 metres (3,300 yd) away. The smoothbore gun and the ATGM launching system were to be mounted in a compact one-man turret from the Tula Instrument Engineering Design Bureau (KBP).

2A28 Grom

2A28 Grom

The 2A28 Grom is the main armament of the BMP-1 and BMD-1 infantry fighting vehicles. It is a 73 mm low pressure smoothbore semi-automatic gun with a wedge breech block. Development of the 2A28 Grom was directly linked to that of the SPG-9 recoilless gun; both fired projectiles similar to rocket-propelled grenades.

Firing points

Firing points

A firing point is a prepared fighting position from which infantry can defend territory with minimal exposure to return fire. Construction ranges from simple sandbag walls to sophisticated, permanent fortifications. Large artillery emplacements, for example, are vulnerable to attack by lightly armed and mobile troops who can avoid the primary armament's field of fire by dispersal or stealth, or by taking advantage of the limitations in the weapon's traverse or depression. Military engineers typically include firing points in these constructions, allowing defenders to deflect such an attack. This includes slit trenches, pillboxes, and redoubts.

KBP Instrument Design Bureau

KBP Instrument Design Bureau

JSC Konstruktorskoe Buro Priborostroeniya (KBP) is one of the main enterprises in the field of Russian defense industry, based in Tula. It is engaged in designing high-precision weapon systems for the Army, the VMF and the VKS, as well as anti-air defense systems, high-rate-of-fire cannons and small arms, in addition to civilian products. Its full name goes as "Joint-Stock Company Instrument Design Bureau named after Academic A. G. Shipunov". Its shareholders include High Precision Systems, part of the State Corporation Rostec.

Prototypes

The requirements were issued to the various design bureaus between 1959 and 1960. There was a question as to whether the BMP should be tracked or wheeled, so a number of experimental configurations were explored including hybrid wheeled/tracked designs. The prototypes (designated as "objects" according to Soviet classification) were:

  • Ob'yekt 1200 from Bryansk Automobile Works (BAZ), 1964 - an 8-wheeled design, similar to the BTR-60PB APC. Like the said APC, the Ob'yekt 1200 prototype had a rear engine design which counted against it. It was eliminated because its cross-country ability (especially in snow and deep mud) was similarly mediocre to the said APC due to the overweight of the 8 x 8 chassis.
  • Ob'yekt 911 from the Volgograd Tractor Works (VTZ), chief designer I. V. Gavalov, 1964 - was a hybrid tracked design, with 4 additional retractable wheels for high speed road travel. The complex design was felt to offer no advantages.
  • Ob'yekt 914 from the Volgograd Tractor Factory (VTZ), chief designer I. V. Gavalov, 1964 - was a tracked design and a variant of Ob'yekt 911. Based on the PT-76 amphibious light tank chassis with a similar armament to other BMP prototypes (except the Ob'yekt 914 was also armed with two 7.62 mm PKT machine guns mounted in the hull on both sides of the driver). It weighed 14.4 tonnes, had a crew of two and could transport up to eight fully equipped soldiers (two of whom operated the PKT machine guns). The rear engine design counted against it, forcing infantry to mount and dismount through the single door in the rear of the right hand side of the vehicle and roof hatches. It was also felt that the Ob'yekt 764 had a better layout. Work on the experimental Ob'yekt 914 helped a lot in the following layout development of the BMD-1 (Ob'yekt 915) airborne infantry fighting vehicle.
  • Ob'yekt 19 from the Altai Tractor Plant in Rubtsovsk, 1965 - was a 4 x 4 wheeled design with retractable tracks between the wheel axles which were intended for crossing rough ground. Once again the very complicated hybrid design was felt to offer no clear advantage over a tracked design.
  • Ob'yekt 764 from the Chelyabinsk Tractor Works (ChTZ); chief designer P. P. Isakov, 1964-1965 - the main prototype of the BMP was equipped with a waterjet for swimming (the waterjet was later removed to save interior space). After it passed the trials, it was improved and became the BMP-1 (Ob'yekt 765).

During this time, the United States had successfully introduced the M113 armored personnel carrier in the Vietnam War in 1962. Though not designed as a combat vehicle, its light armor and mobility was effective against most small arms employed by the Viet Cong forces. It had been adapted into an infantry fighting vehicle with the fitting of an open turret and gun shields. Unlike the BMP, it lacked the firepower and armor to defeat and survive against other armored combat vehicles. After the appearance of the BMP, the US responded with a series of infantry fighting vehicle designs, starting with the MICV-65, although nothing entered service until the M-2 Bradley appeared during the early 1980s.

A number of designs were studied as part of the MICV project, but none of them entered service for a variety of reasons. Nevertheless, experience gained in the MICV project eventually led to the M2 Bradley, which incorporates many of the MICV concepts.

Ob'yekt 765

The tracked Ob'yekt 764 was chosen, after a few improvements, because its front engine design provided a convenient and fast way of mounting and dismounting through two rear doors. As a result of its rather weak armor, the BMP was relatively light and required little preparation for amphibious operations.

The original production prototype, which was built in 1965, was designated BMP.[3] Small-scale production began in 1966 at Chelyabinsk to permit field trials, although the Kurgan Machine Building Plant (KMZ) was converted to BMP production as Chelyabinsk was committed to tank production. A number of defects were corrected between 1966 and 1970 resulting in four slightly different production design variants of the first models. (Ob'yekt 765Sp1 and Ob'yekt 765Sp2). The key changes made to the design were:

  • The suspension was strengthened to cope with high speeds.
  • A new chemical filter system was fitted on the left hand side of the turret in addition to the already existing radiological protection system.
  • The openly mounted air filtration system was moved from the left hand side of the hull to a separate compartment inside the vehicle behind the commander's station.
  • The fume extractors for the firing ports were moved to eject the fumes to the rear of the vehicle.
  • The trim board was modified.
  • The new air intake was fitted with a low snorkel to prevent water flooding the vehicle while swimming.
  • The fender profile was modified.
  • The detachable hatch cover over the engine compartment was replaced with a hinged cover.
  • The Commander's hatch was fitted with a torsion bar, the troop hatches were fitted with key locks.
  • The tool stowage boxes on the fenders were removed.
  • Firing ports (one on each side) were provided for the squad's PKM general purpose machine gun.
  • The 9S428 ATGM launcher was improved to fire 9M14M 'Malyutka-M' (AT-3B Sagger B) ATGMs.
  • The nose section of the hull was modified and extended by 250 mm to shift the center of gravity to prevent the nose section from being too heavy, it could often cause "submarining" when swimming. The height of the hull was slightly increased for the same purpose.

Further improvements included a new 1PN22M2 sight, turn signals, and many smaller details, (for example, mounting the trim vane on six hinges instead of two, improved hermetic sealing of the commander's hatch, new construction of the gunner's seat, etc.). All those changes resulted in the combat weight increasing from 13.0 tonnes to 13.2 tonnes. Series production of the final production model, the Ob'yekt 765Sp3 (NATO: BMP-1 Model 1970), began at the Kurgan Engineering Works in 1973.

Models

A large number of variants of the BMP-1 were produced. The most notable IFV variants based on the BMP-1 were: BMP-2, MLI-84 and Boragh.

Although the BMP-1 was a revolutionary design, its main armament, the 2A28 Grom and the 9S428 ATGM launcher capable of firing the 9M14 Malyutka (NATO: AT-3A Sagger A) and the 9M14M Malyutka-M (NATO: AT-3B Sagger B) ATGMs, quickly became obsolete. Therefore, the Soviet Union decided to produce an updated and improved version of the BMP-1. The main emphasis was put on improving the main armament. In 1972 work got underway to develop an improved version of the BMP-1. An experimental prototype, the Ob'yekt 680 was produced. Ob'yekt 680 had a new two-man turret armed with a Shipunov 2A42 30 mm autocannon and a secondary 7.62 mm machine gun mounted in a barbette similar to the Marder.

The BMP-1 was to be tested in combat in the October 1973 Yom Kippur War. Egypt received 230 BMP-1s in 1973. Syria had received between 150 and 170 by the start of the war, of which about 100 were committed to the front line. Israeli forces captured or destroyed 40 to 60 Egyptian BMPs and 50 to 60 Syrian BMPs, mechanical problems accounting for a large number of the Syrian losses.

The BMP proved vulnerable to .50 caliber machinegun fire in the sides and rear, and to infantry-based 106 mm recoilless rifles. The need to keep some of the roof hatches open to prevent the vehicle from overheating meant that the vehicle could be disabled by machinegun fire from infantry on higher ground shooting into open hatches. The 73 mm gun proved inaccurate beyond 500 meters, and the AT-3 Sagger missile could not be guided effectively from the confines of the turret. The BMP-1's low profile means that it was difficult for the BMP to fire over the heads of the advancing infantry it was supporting.

On the positive side, the vehicle was praised for being fast and agile. Its low ground pressure enabled it to navigate the northern Kantara salt marshes where other vehicles would have bogged down. Its ability to swim proved useful: it was used in the first wave of canal crossings by the Egyptians.

Several Soviet technical teams were sent to Syria in the wake of the war to gather information. These lessons combined with observations of western AFV developments resulting in a replacement program for the original BMP in 1974.

The first product of this program was the BMP-1P upgrade intended as a stopgap to address the most serious problems with the existing design. Smoke grenade launchers were added to the rear of the turret and the manually guided AT-3 Sagger missile system was replaced with the semi-automatically guided AT-4 Spigot and AT-5 Spandrel system. The new missiles were somewhat difficult to use since the gunner had to actually stand out on the roof to use the weapons, exposing himself to hostile fire. The BMP-1P was in production by the late 1970s and existing BMP-1s were gradually upgraded to the standard during the 1980s.

A development program to completely address the shortcomings of the BMP was started at the same time resulting in four prototypes, all of which had two-man turrets.

  • Ob'yekt 675 from Kurgan - BMP-1 hull, armed with a 2A42 30 mm autocannon. This eventually became the BMP-2.
  • Ob'yekt 681 from Kurgan - BMP-1 hull, armed with a lengthened 73 mm gun.
  • Ob'yekt 768 from Chelyabinsk - Lengthened hull with 7 road wheels and armed with a lengthened 73 mm gun.
  • Ob'yekt 769 from Chelyabinsk - Lengthened hull with 7 road wheels and armed with a 2A42 30 mm autocannon.

The commander was moved inside the turret on all of the prototypes because of the dead zone created by the infra-red searchlight when he was seated in the hull, additionally the commanders view to the rear was blocked by the turret. The new two-man turret took up much more space in the hull than the original one-man turret resulting in a smaller crew area. A lengthened version of the original 73 mm gun was considered, but after some debate the 30 mm gun was selected for the following reasons:

  • It offered higher maximum elevation - a critical factor in Afghanistan, where the limited elevation of the gun caused problems.
  • The high-velocity gun had better maximum range (2000–4000 meters) that would allow the BMPs to support the tanks spearheading any assault.
  • It also offered a useful anti-helicopter capability.
  • The 73 mm gun had been mounted on the older BMP-1 to retain anti-tank capability as a basic doctrine design specification. With the introduction of Chobham armour on NATO tanks, the 73 mm gun became ineffectual and obsolete, and given a lack of a suitable gun design as a replacement in this role at the time, a 30 mm gun was introduced as a replacement, notably with an anti-helicopter role as a new threat emergent since the Vietnam War. (Perrett 1987:77) The anti-tank capability was however retained in the BMP-2 with the continued use of anti-tank guided missiles. The new vehicles now allowed the gunner to fire 9K111 Fagot (AT-4) and 9M113 Konkurs (AT-5) missiles from within the protection of the turret.

Eventually the Ob'yekt 675 was selected to become the BMP-2, probably because a new hull design would have required extensive retooling at BMP production plants.

9M14 Malyutka

The 9M14 Malyutka is a manual command to line of sight (MCLOS) wire-guided anti-tank guided missile (ATGM) system developed in the Soviet Union. It was the first man-portable anti-tank guided missile of the Soviet Union and is probably the most widely produced ATGM of all time—with Soviet production peaking at 25,000 missiles a year during the 1960s and 1970s. In addition, copies of the missile have been manufactured under various names by at least six countries.

Egypt

Egypt

Egypt, officially the Arab Republic of Egypt, is a transcontinental country spanning the northeast corner of Africa and southwest corner of Asia via a land bridge formed by the Sinai Peninsula. It is bordered by the Mediterranean Sea to the north, the Gaza Strip of Palestine and Israel to the northeast, the Red Sea to the east, Sudan to the south, and Libya to the west. The Gulf of Aqaba in the northeast separates Egypt from Jordan and Saudi Arabia. Cairo is the capital and largest city of Egypt, while Alexandria, the second-largest city, is an important industrial and tourist hub at the Mediterranean coast. At approximately 100 million inhabitants, Egypt is the 14th-most populated country in the world.

Recoilless rifle

Recoilless rifle

A recoilless rifle, recoilless launcher or recoilless gun, sometimes abbreviated "RR" or "RCL" is a type of lightweight artillery system or man-portable launcher that is designed to eject some form of countermass such as propellant gas from the rear of the weapon at the moment of firing, creating forward thrust that counteracts most of the weapon's recoil. This allows for the elimination of much of the heavy and bulky recoil-counteracting equipment of a conventional cannon as well as a thinner-walled barrel, and thus the launch of a relatively large projectile from a platform that would not be capable of handling the weight or recoil of a conventional gun of the same size. Technically, only devices that use spin-stabilized projectiles fired from a rifled barrel are recoilless rifles, while smoothbore variants are recoilless guns. This distinction is often lost, and both are often called recoilless rifles.

Chobham armour

Chobham armour is the informal name of a composite armour developed in the 1960s at the British tank research centre on Chobham Common, Surrey. The name has since become the common generic term for composite ceramic vehicle armour. Other names informally given to Chobham armour include Burlington and Dorchester. Special armour is a broader informal term referring to any armour arrangement comprising sandwich reactive plates, including Chobham armour.

Anti-tank guided missile

Anti-tank guided missile

An anti-tank guided missile (ATGM), anti-tank missile, anti-tank guided weapon (ATGW) or anti-armor guided weapon is a guided missile primarily designed to hit and destroy heavily armored military vehicles. ATGMs range in size from shoulder-launched weapons, which can be transported by a single soldier, to larger tripod-mounted weapons, which require a squad or team to transport and fire, to vehicle and aircraft mounted missile systems.

BMP-3

The design of the BMP-3 or Obyekt 688M can be traced back to the Obyekt 685 light tank prototype with 100 mm gun 2A48-1 from 1975. This vehicle did not enter series production, but the chassis, with a new engine, was used for the next-generation infantry combat vehicle Obyekt 688[5] from A. Blagonravov's design bureau. The Ob. 688 weapons configuration—an externally mounted 30 mm gun and twin Konkurs ATGM launcher—was rejected; instead the new 2K23 armament system was selected. The resulting BMP-3 was developed in the early 1980s and entered service with the Soviet Army officially in 1987. At the moment the BMP-3 is the most modern, in service, tank of the BMP series while it is supposed to be replaced by the BMP T-15 Armata which is currently in the prototype stage.
