Poudreries Réunies de Belgique SA (or PRB) was one of Belgium's oldest and largest manufacturers of munitions, once the second-largest Belgium armaments manufacturer. The company indirectly started in 1778 in Wetteren as a gunpowder factory. By its 200th anniversary in 1979 it had 73 factories throughout the world, with the headquarters in Brussels. PRB finally became bankrupt in 1993 after being demilitarised in 1990 with parts sold to the Luchaire Defense SA, part of Giat Industries (now known as AFAIR Société Nouvelle PRB SA)
