BTR-D (1974)

Airborne Armoured Personal Carrier - circa 500 built

The Soviet Airborne APC

The BMD-1 of 1969 was the world's first airborne IFV, entering service with the Soviet Army, but keeping many flaws due to its compromised nature. Notably a cramped troop compartment which barely accomodated four infantrymen. In practice it was more often three, both to carry the necessary equipment and efficiently dismount. In the beginning of the 1970s, the Volgograd Tractor Factory design bureau under the leadership of A. Shabalin (the original designer of the BMD-1) started working on a derivative version based on the same chassis. The goal was to make it longer, but not heavier. It was intended primarily for the transportation of airborne personnel, airbone, and to reduce costs, shared as many parts from the previous BMD-1 airborne assault vehicle was possible, starting with the chassis. The prototype was tested in 1973, and accepted with little modififications.

This serial airborne APC was completed in 1974, approved for production entering service the same year a "BTR-D". Since then, it was largely produced in the hundreds and deployed within all Soviet paratroopers units. It is still in service to this day, after seeing service in Afghanistan and other theaters of operations, and also in use in other countries. The BTR-D also benefited of a larger chassis and was declined a whole range of variants, most famous of which being the 2S9 Nona-S (see later).

Design

The base layout of the BMD-1 was preserved with its engine compartment aft of the hull, followed by the troop compartment and the driver's section forward. Like the BMD-1, the vehicle has a fully enclosed sealed body for NBC protection. Its hull is assembled by welding, using a high-strength aluminum armor. Due to the small mass required, the level of protection is limited to small arms fire and shell fragments, plus small mines. Compared to the BMD-1 howeve rits body is much longer, increased by 48,3 cm and the adjonction of an extra roadwheel. It is slightly better due to the upper front armour having a more slanted angle. It is overall also 60 cm higher and have a small flat superstructure with a hatch on top. The crew consisted of the driver, commander and left bow machine gun gunner, same positions and equipment as in the BMD-1. The driver could see through its hatch when lifted up, or three interchangeable periscopes, the central one swappable with an infrared night vision device. Two seats are installed either side of the driver, one manning a 7.62-mm PKT machine gun, mounted in the upper frontal armor plate in a ball mount. For communication, each vehicle is given a R-123M radio station. For active protection, the BTR-D is also given four 902V smoke grenade launchers. The crew is protected inside from fire by an automatic fire-fighting system, plus the full NBC lining and overpressure. The BTR-D carried overall the same equipment as the BMD-1 plus towing equipment for a ZU-23-2 twin AA autocannon.

Powerplant

The engine compartment is essentially the same as in the BMD-1, housing a diesel V6, liquid-cooled, 5D20. It was rated to 177 kW. Its main clutch, gearbox and side clutches were combined in a compact single power unit with the engine. The BTR-D ressts on six rubberized road wheels and five support rollers per side. The drive sprokets at the back, to avoid using a transmission shaft and keep the vehicle low. Suspension comprises individual hydropneumatic arms like on the BMD-1, allowing to radically change ground clearance from 110 mm to 450 mm. Itt can also change the track tension. This airborne APC uses also the same steel fine-link tracks, with a rubber-metal hinge. Performances are good, also high maneuverability on rough terrain. It was tested capable of climbing a 32-35 ° slope, a 0.7 m vertical wall, 2 m wide trench. It was capable of crossing rivers at 10km/h when swimming, using two water-jet propellers.

Armament

The hull comprises two frontal ball-mounted MG, while the troop compartment section, higher than on the BMD-1, comprises and observation windows placed in the frontal armor plate of this compartment, closed by armored shutters. Two more 7.62-mm PKT machine guns could be installed in pistol ports's ball mounts, to fire on the move plus another in the back exist hatch. Variants introduces either a rotating remote turret (PKT MG) on the roof of the troop compartment, or two 7.62-mm PKSM machine guns, one 30-mm automatic grenade launcher AGS-17 "Flame" at the front. The "human armament" is carried by the vehicle: Ten fully equipped paratroopers. They dismount through two hatches in the roof of the troop compartment or the back door aft. These pistol ports are assisted by Periscopic observation devices. So technically the base APC could fire five PKTs on the move. The paratroopers had they own AK-47s and grenades, portable mortar, and in the 1970s, small AT missiles (like the "Spandrel") could be carried by reducing the crew. The standard onbooard became the PKB general purpose machine guns in the 1980s, and pintle-mounted automatic grenade launchers like the AGS-17, AGS-30 or AGS-57 could be fitted as well as PKM, 6P41, "Utyos" or "Kord" machine guns.

Variants

BTR-DG (Ob'yekt 925G)

Cargo variant without bow machine guns, firing ports and periscopes. The troop compartment was modified to serve as a cargo compartment. At least one was converted into an airborne SPAAG fitted with a specially built three-legged ZU-23-2 twin anti-aircraft autocannon mount over the roof of the cargo compartment.

BTR-D San

BREM-D

(BREM-D stands for bronirovannaya remonto-evakuatsionnaya mashina desanta – armoured maintenance-recovery vehicle of the airborne) (Ob'yekt 932) – BTR-D converted into an airborne ARV. It carries specialized equipment for the repair and recovery of BMD-1 type vehicles. This equipment includes a light collapsible crane stored on the roof of the personnel compartment, which can be traversed through 180°, a recovery winch, a combination spade and dozer blade, a generator, towing equipment, electric welding system, tools and ready use spares. One of the 7.62 mm bow PKT tank machine guns was eliminated. This entered service in 1989 in very small numbers.
