Russian APC/IFV Design Overview

A typical example of a Soviet styled wheeled APC is the BTR-80. The BTR-80 is a 30,000 pound (13.6 tonne) 8×8 wheeled APC which is approximately 25 feet (7.7 meters) long, 9.5 feet (2.9 meters) wide and 8 feet (2.4 meters) high. Operated by a crew of three with a driver, commander and gunner the vehicle also transport 7 infantry troops. The driver and commander are situated to the forward of the vehicle while the gunner is positioned in a roof mounted seat beneath the main weapon. Two of the troops are located forward of the driver and commander, while the other five sit on bench style seats in the back of the vehicle. The troops are provided with firing ports. The rear positioned troops enter and exit the vehicle through side doors that are split. The upper door swings to the side and the lower half descends downward, thereby acting as a stepping surface. This approach is supposed to let troops exit the vehicle while it is in motion, with the side of the vehicle having the doorway oriented away from enemy fire.

The BTR-80 is powered by a 260 hp V-8 turbocharged diesel engine which provides a power-to-weight ratio of 17 hp/ton. This is a significant improvement over the dual gasoline engines that powered the earlier BTR-60 and BTR-70. Able to attain road speeds of up to 55 mph (90 km/hr) and having an operational range of 370 miles (600 kms) with on-board fuel the vehicle is also fully amphibious with a water speed of 6.2 mph (10 km/hr). The vehicle is powered through the water through hydrojets. The vehicle is able to navigate a gradient of 60% and climb a vertical step of 1.6 feet (0.5 meters).

A large number of variants of the BTR-80 have been produced to meet various operational needs and customer requirements. The more common of these are noted below:

• BTR-80 – standard Armored Personnel Carrier (APC) produced in 1986.

• BTR-80M – enhanced version available in 1993 with improved engine and tires.

• BTR-82 – further enhanced version available in 2009 with increased armor, addition of spall liner, improved night vision equipment and a 300 hp engine.

• 2S23 – a fire support version of the vehicle, mounting a 120 mm mortar rifled gun.

• BTR-80A – An Infantry Fighting Vehicle version introduced in 1994 and equipped with the remotely operated 2A72 30 mm auto-cannon in the turret and provided with 300 rounds of ammunition.

• BTR-82AM – A Naval Infantry (Marines) version of the BTR-82A.

• BTR-82A – Further enhanced IFV introduced in 2009 that has been well received by Russian troops battling in Ukraine. Weapon system has a FCS and improved night vision optics. Includes increased armor, addition of spall liner to the vehicle interior, GLONASS navigation system and a 300 hp engine. The vehicle is also able to accommodate 8 dismounts.

A typical example of a Soviet styled tracked vehicle is the BMP-1. BMP-1 – Modernized by the Belarusian 140th Repair Workshop from Barysaw in Belarus during major repairs between the 1970s and 2000s (decade). The modernization package included the pintle-mounted 9P135M-1 ATGM launcher capable of firing SACLOS guided 9M113 “Konkurs” (AT-5 Spandrel), 9M113M “Konkurs-M” (AT-5B Spandrel B), 9M111 “Fagot” (AT-4 Spigot) and 9M111-2 “Fagot” (AT-4B Spigot B) ATGMs as well as a new electronic pulsed infrared jam-resistant weapon system.

Armored Personnel Carriers became common during World War II, originally introduced by the German army to rapidly transport troops along the battlefield front. Capable of transport under conditions that regular trucks could not traverse, this provided tactical mobility to support the Blitzkrieg (lighting war) form of war. The Infantry Fighting Vehicle, essentially an APC styled vehicle with enhanced armor and armaments, was introduced during the 1960s by the Soviet Union. Its role was to provide fire support to dismounts and to engage lighted armored vehicles.

A weakness of APCs and IFVs is that they could not be armored sufficiently to protect against RPGs and ATGMs. Therefore modern warfare techniques rely heavily upon mobility, with tanks, IFVs and APCs advancing quickly upon enemy units. Supported by artillery and infantry to suppress the deployment of shaped-charged warhead equipped weapons, the armored vehicle are expected to overwhelm the enemy before they can effectively deploy their RPGs and ATGMs. This method of rapid mobile combat, known as maneuver warfare, was designed to engage in a successful full-scale conventional confrontation, as combat in Europe might unfold.

Modern warfare however has tended toward descending into asymmetric warfare and urban combat, with Armored Fighting Vehicles (AFVs) often operating from isolated or stationary positions. This once again left them vulnerable to attack by infantry armed with RPGs and man-portable ATGMs. As Russians incurred heavy losses in the insurgent warfare experienced in their Afghanistan War and in Grozny during the 1st and 2nd Chechen Wars, they painfully came to recognize these vulnerabilities. Many Russian IFVs and APCs were destroyed by poorly trained but well-motivated infantry armed with relatively simple and inexpensive RPGs, ironically typically of Russian origin.

Multiple approaches were devised to overcome these vulnerabilities. These included having infantry outside the vehicle as it moved through cities to provide it protection, positioning troops at the vehicle front to operate defensive weapons, increasing the firepower available to the vehicle crew to destroy hostile enemy before they could deploy their weapons, installing lighter versions of ERA on these vehicles (the heavy tank versions of ERA damage the thin skinned IFVs and APCs) and to develop softkill and hardkill APS systems. The other approach is simply to provide APCs and IFVs with the same level of protection provided to MBTs (i.e., use tank chassis as APC/IFV chassis). Though the light-weight aspect of these vehicles is sacrificed by this approach, their survivability in insurgent and urban warfare is significantly improved. This has resulted for example in the development of the T-15 from the T-14. The Israelis are also taking this approach, developing the heavily armored Namer from the Merkava.

Soviet and Russian IFVs and APCs share regularities in their design approach, reflective of their military encounters, with designs evolving to meet the challenges presented by emerging technologies and tactics. Much like their Western counterparts, the Soviets field both wheeled and tracked APCs and IFVs that can be produced as a ‘Family of Vehicles’. Similar to the West, Soviet/Russian IFVs tend to be more heavily armored than their APCs. The IFVs ALSO tend to be tracked, permitting them the ability to maintain pace with MBTs, which their principal role is to support. For APCs however the Russians has long shown a preference for wheeled vehicles, with the West only absorbing the long established Russian approach in the 1990s. The Russians also have a strong preference for building APCs and IFVs that can ‘swim’, able to traverse rivers they encounter during an advance. While Western vehicles tend to stress higher armor levels, and therefore greater weight, the Russians keep their vehicle light enough to permit swim capabilities.

Until recently the Soviets in general have shown less interest in protecting their crews and providing for their comfort than their Western counterparts, focusing more on keeping their vehicles small, mobile and fast. Where Western vehicles tend to be taller and larger, providing more space for the occupants, Russian APCs and IFVs tend to be very low and flat by comparison, minimizing both the silhouette and vehicle weight. They also tend to be wider, and have wider tracks or wheels. Combining these features provides for optimized vehicle mobility, making them fast, able to traverse steep banks (low Center of Gravity) and able to navigate mud and snow.

The disadvantage of this approach is that the vehicle crew and dismounts (transported troops) have to operate is very cramped conditions. Therefore crews become exhausted more quickly, have more difficulty operating equipment and suffer higher casualties when the vehicle armor is breached due to slow and difficult vehicle egress. To counter these restrictions the Soviets have actually devised some rather novel innovations to improve the conditions for the crew and dismounts, and to improve overall vehicle performance.

Where older models of Russian APCs and IFVs have the transported troops enter and exit the vehicle from highly constrictive side doors, newer designs provide troops access through large doors and folding roofs at the vehicle rear. And where the loading rate of the main weapon was often only a quarter of that achievable on the more open spaced Western vehicles, integrated autoloaders has provided Soviets vehicles reload rates equal to or better than those achieved by their Western counterparts.

Another novel feature devised by the Soviets was to place the engine of their IFVs in the rear of the vehicle, providing it greater protection, similar to MBTs (IFVs and APCs more often place the engine at the vehicle front, to the right of the driver). By placing the engine low in the vehicle, troops are able to enter the vehicle over the rear mounted engine. This also permits the driver to be positioned in the center of the front of the vehicle, also similar to typical MBT design. The Soviets then place a soldier on either side of the driver, each operating as a machine gunner or grenade launcher operator. Similar to some WWII tanks, in which a weapons operator sat alongside the vehicle driver, this approach provides substantially greater firepower that can be directed at infantry to protect the vehicle from attack by RPGs and ATGMs.

Much like Western vehicles the Soviets fabricate their vehicle hulls from welded ballistic aluminum and/or ballistic steel, providing all around 360 degree protection to lower calibre threats. The vehicles possess highly sloped frontal glacis plates as well as sloped sidewalls, the oblique surfaces more effectively deflecting incoming rounds. While this reduces space availability for crew and troops, it does enhance vehicle overall survivability. With their low vehicle profile, Soviet APCs and IFVs are also more challenging to hit than their higher standing Western counterparts.

The Soviet approach to increasing the protection on their vehicles beyond the inherent capabilities of the hull have historically been more progressive than Western thinking. In many ways the Soviets have led the way in innovative armor developments, with the West later duplicating their advancements. Having led the way in developing ATGMs, the Soviets foresaw a need to counter such weapons, and so were first to develop ceramic armor solutions. As well the Soviets led the way in the development of ERA, electronic countermeasures (soft kill dazzlers and jammers) and hardkill Active Protection Systems. They also remain the only military to have integrated ERA directly into hull designs, and have APS as a standard system on their AFVs.

The Soviets also tend to more heavily arm their IFVs than equivalent Western vehicles. This includes deployment of multiple guns installed on a single turret, such as the dual 100 mm gun / 30 mm autocannon on the BMP-3 and BMD-4. Their main weapons also tend to be more multi-functional in terms of ammunition that can be fired than Western vehicles, often able to fire ATGMs as well as the standard KE and/or HE-I rounds. This provides them greater firepower and an extended maximum effective combat range. Additionally most modern Russian IFVs can be armed with various turret mounted ATGM systems. Vehicle protection is enhanced by offering firing ports to troops and positioning soldiers at the front of the vehicle to operate machine guns and grenade launchers. This set-up is particularly effective in suppressing infantry units trying to engage the vehicle.

Perhaps the most defining aspect of Soviet/Russian APC and IFV design, similar to their MBTs, is low cost and simple design. Soviet experiences in World War II convinced them that to defend their nation and to overwhelm and invader, they must be able to produce huge numbers of armored vehicles. This necessitates that the vehicles be inexpensive and fast to build. Where Western vehicles are built to a high quality standard and utilizes expensive components and advanced technologies, Soviet experience recognizes that armed forces are expended rapidly once conflicts erupt and must be able to be rapidly replaced. Therefore the fabrication quality of Soviet armored vehicles tends to be poor compared to Western vehicles and the use of sophisticated technologies is generally restricted.

A negative result of this approach has been that the Soviets fell behind significantly in the advancement of integrated computerised systems and sensor technologies. While this lack of sophistication was not disadvantageous is the early cold-war period, computerised capabilities and advanced sensors have become critical in modern AFVs, as they are essential for operating the Fire Control Systems that permit cannon to accurate fire on the move, for providing night fighting capabilities through use of thermal imaging, and for the guidance of advanced munitions.

Recognizing that in a modern ultra high-tech environment that an overly simplified AFV will not survive for long, and that replacing lost vehicle with more low quality units won’t suffice to win a battle anymore, the most recent generation of Russian designed vehicles, the T-14 and T-15, are making a clean break with traditional Soviet design. A new emphasis is being placed on crew and troop survivability, and inclusion of high tech equipment and capabilities. However, due to the relative distance that the Soviets have fallen behind in these aspects, they are actually reliant on Chinese and French computers and sensors to equip their latest generation of vehicles until they are able to catch up and develop these components within Russia.
