In May, we reported on the acquisition of DOMAR MS by the Czech industrial and defence group Czechoslovak Group (CSG). The Warsaw-based company is 1 of the key players in the market, offering comprehensive manufacturing of cable harnesses, fiber-optic systems, control boxes and panels, and components for the most demanding applications—ranging from military and aviation to space. We spoke with Bolesław Janczewski, CEO, about the beginnings, development, challenges, and future of DOMAR MS.
