MSM GROUP Ltd. was established by transformation of MSM Martin Ltd., which dealt with construction, development, production and sales mainly with military material. MSM Martin Ltd. in the last few years took over several military companies located in the middle of Slovakia, and built on its traditional manufacturing activities in military and civil production. Due to ZVS inclusion into the group structure the company can state that the origin of MSM GROUP Ltd. comes back to 1927 when then Škoda Works in Plze?, as a monopoly producer of ammunition decided to build so called „spare factory“ in Slovakia. The company was totally destroyed during the World War II, and it took several years while the production was restored to such extend, that its products were supplied not only for
the Ministry of National Defence, but for many countries worldwide as well. Today the MSM GROUP Ltd. makes use of rich experiences from the past and knowhow of highly qualified workers and vast archive of technical documentation for all necessary procedures. In 2009 the biggest Czech military holding CSG (CZECHOSLOVAK GROUP) entered MSM as a co-owner.
