    The department was founded in 1981 by the merger of departments No. 38 (head of department, Doctor of Science S.L. Mandelberg) and department No. 224 of RESEARCH DESIGN AND TECHNOLOGY BUREAU (head of department, Doctor of Technology A.O. Rybakov). At the same time, the department included a group of tanks.
