On 5 December 1991, by the decision of the Government of the Armenian SSR, the State Defence Committee under the Council of Ministers was created.

The police patrol and special operations regiment of the Ministry of Internal Affairs of Armenia, the civil defence regiment of the Civil Defence Headquarters of the Republic of Armenia and the republican military commissariat were transferred to the subordination of the newly formed ministry.

The next step was the creation of the central apparatus of the Ministry of Defence, which included the Main Headquarters and management.

The formation of the military department coincided with the beginning of large-scale operations in the First Nagorno-Karabakh War, in which the Armed Forces of Armenia actively participated.

Auxiliary buildings include a swimming pool, boiler room, sports grounds and complex, checkpoints, barracks, centralized communication system, shooting range, a closed and spacious parking lot and a large helipad.
