These machines differ typical four-axis location - average close together, front and rear spaced and managed.

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".

BAZ developed and manufactured platforms various Soviet and Russian SAM systems such as 9K33 Osa and S-400.
