PGZ, Poland's largest defence technology manufacturer and partly state-owned, comprises around 60 companies. It plays a key role in the rearmament of the Polish armed forces. This is particularly true when it comes to upgrading armoured land vehicles to protect the country's borders. “The fact that PGZ has chosen us as a potential partner for deeper cooperation is both a recognition of our collaboration to date and an incentive to work towards a successful future together,” said Andreas Görtz, President Mobile & Sustainable Business Unit at Rolls-Royce Power Systems.
