The Ural-4320 military all-wheel drive car was produced in 1977. It was popular and widely distributed due to its high operational qualities, and the production of its modernized versions is still ongoing. The car has many versions, among which there are versions with bodies of the “KUNG” type – closed van bodies for the installation of special equipment and transportation of personnel. Initially, they were made of wood, later – using metal. These van bodies were developed for specific car models, but they were also universal, which made it possible to use them on different chassis. In addition to special army equipment, such van bodies were equipped with heating, ventilation, and lighting systems. A significant quantity of Ural-4320 cars with such closed bodies continues to be used in the Armed Forces of Ukraine.
The Ural-4320 is a military, all-wheel drive all-wheel drive (6x6) truck, originally Soviet, and now Russian. UralAZ plants based in the city of Miass are responsible for its production. Serial production of the vehicle started in 1978 and is still ongoing. The drive was provided by a single engine diesel KAMAZ-740.10 with 210 HP, and since 1993, JaMZ-236 and JaMZ-238 engines with 230 HP.
The Ural-4320 was developed as a modernization and development of the Ural-375D car. The main modernizations involved changing the shape and ergonomics of the driver's cabin, strengthening the structure - especially the suspension - and increasing the load capacity of the truck from 4000-4500 kg to 5000 kg. The power unit was also changed to be much less fuel-consuming and the performance was slightly improved - especially the top speed. The Ural-4320 performs in the Russian army primarily transport tasks - cargo and infantry units, both on the road and in the field. The chassis of this truck also serves as a wheeled platform for the BM-21 Grad rocket launcher.
