The BTR-D is a Soviet airborne multi-purpose tracked APC which was introduced in 1974 and first seen by the West in 1979 during the Soviet war in Afghanistan. BTR-D stands for "Bronetransportyor Desanta" (БТР, Бронетранспортер Десанта, literally "armoured transporter of the Airborne") [http://www.milparade.com/Soderzhaniye.pdf †] . It is based on BMD-1 airborne IFV. NATO gave it the designation BMD M1979.

Development history

In 1969 the BMD-1 airborne IFV entered service with the Soviet Army. The vehicle had many flaws but the biggest was the fact the troop compartment was extremely cramped and could only transport up to four infantrymen although even this number was shortened to three because it was impractical for four infantrymen to operate inside the troop compartment and dismount the vehicle. Because of that in the beginning of 1970s the design bureau of Volgograd Tractor Plant which designed the BMD-1 began designing an airborne APC based on BMD-1. The prototype was ready in 1974 and in the same year after it passed the trials it entered production and service with the Soviet Army as the BTR-D.

Description

Overview

BTR-D is based on BMD-1 however it's 60 mm longer and its turret is removed. A small flat superstructure with a hatch on top of it is in place of the turret.

Crew

The crew consists of the driver, the commander and the left bow mounted machine gun gunner who are in the same positions and have the same equipment like in the BMD-1.

Armament

Although the turret with all of the main armament was removed, the two bow mounted machine guns have been retained. However the original PKT tank machine guns have been replaced by PKB general purpose machine guns. The vehicle can also be fitted with pintle-mounted automatic grenade launchers (AGS-17, AGS-30 or AGS-57) and/or machine guns (PKM, 6P41, "Utyos" or "Kord").

Maneuverability

The BTR-D is powered by the same engine as the BMD-1 however its suspension is longer because the entire vehicle has been lengthened by 60 mm. Because of this the vehicle has six roadwheels on each side instead of five. It also has five return rollers on each side unlike the BMD-1 which has four.

Amphibious ability

Armour protection

The armour protection is slightly better on the BTR-D than on the BMD-1. That's because the upper front armour has a dual slanted angle. Also its armour is made out of aluminium which proved to be much better than the armour on the BMD-1 which was made out of cast magnesium alloy and caught fire and burned fiercely, often killing the crew if hit with a weapon such as an RPG.

Troop compartment

Because the turret has been removed the troop compartment has been enlarged and can carry up to ten fully equipped soldiers. It's also linked with the crew compartment in the front. Also the are two firing ports in the sides and one in the rear, two of which are for RPK-74 light machine gun.

Equipment

BTR-D has all the same equipment as the BMD-1 but also has towing equipment for ZU-23-2 twin AA autocannon.

Air-drop techniques
