The story
Bryansk Automobile Plant was founded 4 June 1958 [1] as a branch of the Moscow factory ZIL for the manufacture of components: driving axles, barrels, boxes handout, suspension and other components for automobiles ZIL-131. The basis for the creation of new business was the manufacture tractor Bizhytskoho steel plant [1]. Already in 1959 from Moscow factory was moved production of vehicles for the army, and in 1960 on the base created a special closed design bureau and independent production. In 1961 the first development of the plant, BAZ-930, was tested, but the series did not go, and instead plant began production modifications Moscow ZIL-135L: ZIL-135LM, with manual transmission, processed BAZ-135MB and BAZ-135MBK. These machines differ typical four-axis location - average close together, front and rear spaced and managed.
In the mid-1960s in the BC plant was begun designing triaxial floating chassis with four-wheel drive. The paper used backlogs and design principles taken from ZIL, such as airborne transmission and extreme steam driven wheels. The result was the design of a family of triaxial chassis BAZ-5937, BAZ-5938 and BAZ-5939 rear engine, which became the basis of machines SAM Osa and BAZ-5921 as well as BAZ-5922 mid-engined, which was based missile system "Point".
From March 1971 by order of the Ministry of Defence KB plant began designing a new series of standardized four-chassis, which received the name "Base". As part of this development was created several models floating ground and chassis widespread. This series of pairwise grouping sets of axles, front pair - controllable.
