The industrial and technology holding Czechoslovak Group (CSG), owned by Czech entrepreneur Michal Strnad, has made its first acquisition within the framework of its expansion into the Unmanned Aerial Systems (UAS) sector. Through its newly established subsidiary AviaNera Technologies a.s., CSG has acquired a 51% stake in the Serbian company MUST Solutions from its founder and majority owner Vladimir Jazarević. The purchase price of the transaction is not being disclosed.

MUST Solutions (Mechatronics Unmanned Systems and Technology Solutions), based in Belgrade, specializes in the development and production of propulsion systems for advanced unmanned aerial vehicles. Its flagship product is a 4,000 N turbofan engine, the only one of its kind developed in Europe, offering significantly lower fuel consumption combined with extended range. In addition, the company produces a 300 N turbojet engine designed for lighter unmanned aerial systems.
The acquisition of MUST Solutions represents the first tangible step in implementing our UAS strategy, which we announced with the establishment of AviaNera Technologies. Our goal is to acquire cutting-edge technologies and know-how in the field of propulsion systems, which are a key component—and often a bottleneck—in the development and production of modern unmanned platforms, said Michal Strnad, owner of CSG. It is the first step toward vertical integration that will allow us to develop and manufacture complete systems, Strnad added.
Founded six years ago, MUST Solutions employs a team of specialists in mechatronics and aerospace engineering. The company operates its own development facilities and a prototype workshop capable of small-scale production. AviaNera plans to invest in expanding these capabilities toward full-scale serial production of engines for both defense and civilian applications.

The strong industrial base of CSG and AviaNera will enable MUST Solutions to grow rapidly. As early as 2026, we expect to deliver several hundred engines to our customers. Production will gradually expand in Europe—including our home base in the Czech Republic—as well as in Asia and the United States, while our R&D center will remain in Serbia, explained Pavel Čechal, CEO of AviaNera Technologies and adds: Our goal is not only to increase production capacity, but also to expand our product portfolio. We are intensively continuing the development of new propulsion units with outstanding performance parameters, which we plan to introduce to the market next year.
When we founded MUST Solutions six years ago, our ambition was to build a European center of excellence for unmanned propulsion systems. The partnership with CSG and AviaNera Technologies is a natural continuation of this mission. It provides us with the backing of a strong industrial group capable of developing and manufacturing our technologies on a much larger scale, said Vladimir Jazarević, founder and former majority owner of MUST Solutions.
The acquisition of MUST Solutions is an important step in building the UAS sector as a major pillar of CSG’s business. Its growth will continue through further acquisitions, partnerships with top industry players, and synergies with other CSG companies active in aerospace, UAS technologies, and large-caliber ammunition production.
