History

History

During the 1960’s, the Soviet Union set out requirements for a new type of vehicle: a BMP (Boyevaya Mashina Pyekhoty), or infantry fighting vehicle. This vehicle would be used to transport troops to the battlefield while still having enough firepower to defend itself. It would be armed with the 73mm 2A28 cannon that fired reactive projectiles, as well as an ATGM “Malyutka”. The BMP-1 was put into production in 1966, and would change the history of armored fighting vehicles forever.

In 1980, the production of the BMP-2 began. The BMP-2 solved various issues with the BMP-1. It used a 2-man turret with a 30mm 2A42 automatic cannon, with a more advanced fire control system with backup from the commander. The “Malyutka” ATGM was replaced with the more advanced “Konkurs” ATGM. The 30mm 2A42 gun could elevate significantly higher than the 73mm 2A28 and thus would allow the BMP-2 to engage targets higher above it, such as aircraft and infantry in an elevated position.

When the American Bradley IFV began to surpass the BMP-2 in several qualities (firepower, armor, and fire control system), a search was began to upgrade the BMP even further.

However, the BMP chassis itself had been essentially exhausted of upgrade options, so the Ministry of Defense set out tactical and technical requirements for a new BMP. The Ministry of Defense clarified the main tasks of the IFV:

“The main tasks of arming infantry fighting vehicles are:

-Suppression of tank-hazardous manpower both openly located and sheltered in trenches, concentrations of infantry and equipment;
-Effective fight against lightly armored targets (BMP, APC, BRM);
-The ability to fight main tanks and other armored targets with enhanced protection;
-Self-defense against attacking planes and helicopters.”

With these requirements in mind, the BMP-3 was developed. It would use a completely new chassis, as well as modern fire control systems and a new universal weapons system containing a 100mm rifled gun launcher, a 30mm automatic cannon, and a 7.62mm machine gun.

The BMP-3 went into production in 1988, and has reminded in service with the successor states of the Soviet Union to this day, and will likely remain in service for years to come. There have been many different modifications and modernizations of the BMP-3, of which I have listed some below.

Design Specifications

Armor Layout

1 = 18mm ABT-102; 2 = 60mm ABT-102; 3 = 16mm BT-70III + 70mm air + 50mm ABT-102; 4 = 18mm ABT-102; 5 = 43mm ABT-102; 6 = 15mm ABT-102; 7 = 13mm ABT-102; 8 = 10mm AMG-6; 9 = 43mm ABT-102; 10 = 15mm ABT-102; 11 = 43mm ABT-102; 12 = 10mm BT-70SH + 70mm air + 60mm ABT-102; 13 = 10mm BT-70SH + 70mm air + 12mm BT-70SH + 60mm ABT-102

The BMP-3 features all aluminum ABT-102 armor; it lessens the damaging effect of rounds hitting the armor, and it is more manufacturable.

“For example, a sheet of ABT-102 alloy with a thickness of 43 mm (this is equivalent in weight 15.6 mm of BT 70-Sh steel) provides protection against the 3OBT projectile when fired from a distance 300 m and a meeting angle of 68 degrees”

“As calculations have shown, the advantages of aluminum armor make it possible to achieve the level of armor protection required by the technical requirements with a weight saving of about 1.7 tons compared to a steel hull”

The BMP-3 makes use of its water deflector shield to both allow for amphibious capability, and to improve frontal armor protection.

Shown below is a diagram of the rear portion of the BMP-3, where dismounts are held. There are 2 hatches in the roof and 2 doors on the rear of the vehicle. Dismounts sit above the power unit.

Armament

IMG_4535

2A70 100mm Cannon

Details

The 2A70 10mm cannon can fire both high-explosive (HE) and anti-tank guided missiles (ATGM) at ranges up to 4,000m.

High-explosive shells are stored in an autoloader with a capacity for 22 rounds (+18 hull stowage, 40 rounds total) and a firing rate of 10 rounds per minute.

Anti-tank guided missiles are stored in a mechanized rack with a capacity for 3 missiles (+5 hull stowage, 8 missiles total).

2A72 30mm Autocannon

Details

The 2A72 30mm autocannon can fire a wide variety of ammunition types, including but not limited to: armor-piercing tracer, high-explosive incendiary, fragmentation tracer, armor-piercing discarding sabot, and armor-piercing fin-stabilized discarding sabot rounds.

The 2A72 itself is a simpler derivative of the 2A42. It consists of far fewer parts has a lower rate of fire. It is recoil operated and not gas operated. The BMP-3 can carry 500 rounds for the 2A72.

PKT 7.62mm Machine Gun

Details

There are 3 PKT machine guns located in the BMP-3: one coaxial, and two located in either side of the hull.

This is the chassis the Khrizantema-S and Kornet-T are built on, but there were proposals to mount many different weapons systems to it. These include the Mistral and Wildcat SAM systems, “the creation of a combat missile system for Bulgaria”, and the 2R2M mortar.

Based on the 2A42, it’s a simplified variant, still dual feed though :-)

Ah, forgot to include the dual feed part. I’ve been writing this for a few hours now so if there’s any inaccuracies let me know!

Also, do you by any chance have any more information on Object 699, specifically the export proposal variants?

The 2S25?

No, I’ve seen a source state that the Object 699 was intended to be exported to various countries and would mount various (notably NATO) weapon systems,

there is a post on secret projects forum about it

I’ve never even heard of the 699, only the 799, and nothing of the caliper of a mobile mortar system.

Also forgot to mention you forgot the 2S38 system, which is based on the BMP-3. :3

There’s a few I missed, I have some photos saved from a few months ago of variants I haven’t mentioned. I’ll update the post later with them when I can, I’m tired of writing rn lol

2S31, my beloved headached’ BMP-3.

If 2S31 has a headache, 2S18 has a brain tumor.

Anyway, I am going to return tomorrow and add details about the fire control system and auto loading mechanism (if I can find good sources for the latter)

Added history section and a new source! Bulletin of Armored Vehicles is an absolute gold mine for material on Soviet Vehicles.
