JMRC VISMOD BMP-2 Russian Amphibious Infantry Fighting Vehicle (IFV)

JMRC VISMOD BMP-2 Russian Amphibious Infantry Fighting Vehicle (IFV) The BMP-2 [BMP = Boyevaya Mashina Pyekhota - Infantry Fighting Vehicle] infantry combat vehicle, fielded in the early 1980's [initially designated BMP 1981], is an improved version of the BMP-1 incorporating major armament changes. The new two-man turret mounts a 30-mm automatic gun with a long thin tube and double-baffle muzzle brake that can be used against aircraft and helicopters. The ATGM launcher on top of the turret can employ either AT-4 SPIGOT or AT-5 SPANDREL missiles, though the AT-5 Spandrel canister is normally mounted. Given the enlarged turret, there are two roof hatches in the rear fighting compartment, rather than the four of the BMP-1, and the the BMP-2 accommodates one less passenger. Each side of the troop compartment has three firing ports with associated roof-mounted periscopes.The BMP-2 is the base IFV of the family, it is designed to support MBTs during an assault and is expected to engage vehicles that are in a similar category to itself. In the centre of the vehicle is the welded steel turret, which seats the commander and gunner, both of whom have hatches. The commander sits to the right and has three day-vision periscopes, a 1PZ-3 day-sight designed for anti-aircraft use with 1×, 2× and 4× magnification, an OU-3GA2 infra-red searchlight, a TNP-165A designator and a TKN-3B binocular sight with 4.75× day magnification and 4× night-sight magnification. The gunner sits to the commander's left and has a smaller rectangular hatch with a rearward-facing day periscope, additionally, there are three other day periscopes facing forward and left. The gunner has a BPK-1-42 binocular sight with a moon/starlight vision range of 650 metres, or 350 metres using the infra-red searchlight, and a TNPT-1 designator. An FG-126 infra-red searchlight is mounted coaxially to the 30 mm cannon. The driver sits in the front left of the vehicle, with the engine in a separate compartment to his right. The driver has his own entry hatch above him, with three day-periscopes. The centre TNPO-170A periscope can be replaced with either a TNPO-350B extended periscope for amphibious operation or a TVNE-1PA night vision scope. An infantryman sits immediately behind the driver, and has a firing port and vision block. TNPO-170A periscopes are used throughout the vehicle and are electrically heated. In the BMP-1 and BMP-2 ammunition is stored near or even inside the compartment, which can lead to a catastrophic failure in case of a hull breach. The BMP-1 and BMP-2 share the same chassis and have almost identical road performance. The BMP-2 is heavier, but also has a more powerful engine to compensate. The BMP-2 is amphibious with little preparation, using hydrodynamic fairings to convert track momentum into water jets. Peacetime regulations require that any BMPs entering water must have a working radio set, since its bearings are not airtight and it can be carried away by currents in case of loss of engine power (the vehicle lacks an anchor). The main armament is a turret with a stabilized 30 mm 2A42 autocannon with dual ammunition feeds, which provide a choice of 3UBR6 AP-T and 3UOR6 HE-T / 3UOF8 HE-I ammunition and 9M113 Konkurs ATGM. The gun has a selectable rate of fire, either slow at 200 to 300 rounds per minute or fast at 550 rounds per minute. The original stabilization provides reasonable accuracy up to a speed of about 35 kilometres per hour. The AP-T ammunition can penetrate 15 millimetres of armour at sixty degrees at 1,500 metres, while a new APDS-T tungsten round can penetrate 25 millimetres at the same distance. A typical ammunition load is 160 rounds of AP ammunition and 340 rounds of HE ammunition. The ammunition sits in two trays located on the turret floor rear. The gun can be fired from either the commander's or the gunner's station. The commander's 1PZ-3 sight is specifically designed for anti-aircraft operation and combined with the high maximum elevation of 74 degrees, it allows the 30 mm cannon to be used effectively against helicopters and slow flying aircraft. The turret traverse and elevation are powered and it can traverse 360 degrees in 10.28 seconds and elevate through 74 degrees in 12.33 seconds. Reloading the BMP-2's 30 mm cannon can be somewhat problematic and can take up to two hours, even if the ammunition is prepared. Additionally, the cannon is normally only used on the slow rate of fire, otherwise, fumes from the weapon would build up in the turret faster than the extractor fan can remove them. The effective range of the 30 mm cannon is up to 1,500 metres against armour, 4,000 metres against ground targets, and 2,500 metres against air targets. A coaxial 7.62 mm PKT machine gun is mounted to the left of the 30 mm cannon, and 2,000 rounds of ammunition are carried for it. On the roof of the turret is an ATGM launcher, on Russian vehicles this fires AT-5 Spandrel missiles, but on export models, it normally fires AT-4 Spigot missiles. A ground-mount for the missile is also carried, allowing it to be used away from the vehicle. The missiles are a substantial improvement on the AT-3 Sagger missiles used on the BMP-1, in both range and accuracy. Behind the turret is the troop compartment that holds six troops, the seventh sits just behind the driver. The troops sit back to back, along the centre of the vehicle. Down each side of the compartment are three firing ports with periscopes. Access to the compartment is by the two rear doors, which also hold fuel tanks, both doors have integral periscopes and the left door has a firing port. In addition to the main weapons, it can carry a man-portable surface-to-air missile launcher and two missiles, and an RPG launcher and five rounds. The vehicle is fitted with a PAZ overpressure NBC system and fire suppression system, and carries a GPK-59 gyrocompass.
