The creation of the state owned enterprise Letecké opravovne Banská Bystrica (Banská Bystrica Aviation Repair Shop) in 1947 as well as its further development was directly related to the building of the Air Force in Czechoslovakia. From the very beginning, the company focused on the electrotechnical production, repairs and servicing of special military equipment of aeronautical ground facilities and for air defence control, control and dispatching centres, remote control systems, meteorological means and, for a short period of time, also ultralight aircraft manufacturing. In 2006, the enterprise was gradually transformed to a public limited company, and later, in 2009, it merged with VOP Trenčín, a. s. In 2014 it was incorporated into MSM Martin, s. r. o. as a separate operation in Banská Bystrica.

The current main nature and purpose of business of MSM Banská Bystrica is the design, manufacture and repair of NARASYS radio navigation systems for civil and military air traffic control, as well as the design and manufacture of MATC (mobile air traffic control) towers according to customer requirements. In addition, the company is marginally still active in the area of repairs and modernization of various types of special equipment of the Armed Forces of the Slovak Republic, the main focus being on radars and air defence.

Other activities of MSM Banská Bystrica include the development and production of starting devices for aircraft and helicopters, as well as designing in the field of modernization of special military radar equipment.

In 2015, the MSM GROUP s.r.o. was founded, covering several important companies engaged in activities within the defence industry. In addition to MSM Martin s.r.o., one of the companies is ZVS. With the creation of MSM GROUP, our company gained not only strong partners, but also an important unifying entity for business activities.
