That depends what counts as a major war.
But both Rheinmetall and Dynamit Nobel are established companies, probably have clientele to sell the stuff, or maybe there are already orders in place.
Apparently these investments are part of the so called "Zrínyi program" which aims to revitalize our arms industry beside modernizing the Defense Forces. We not just buy foreign products (liek Leopard 2, self-propelled artillery, airplanes), but manufacture what we can, and develop what we need, to mitigate dependence. The first one was a deal with a Czech company, bought licenses of small arms, pistol, smg, assualt rifle (I can recall the Cz BREN 2).
