Niewiadow Polish Military Group Joint Stock Company (Niewiadow Polska Grupa Militarna S.A., GPW: GNS) is a Poland-based defense holding company that develops, manufactures, and supplies military armament, combat systems, ammunition, and dual-use technologies for domestic and international defense sectors. The company traces its industrial heritage to the establishment of the Nitrat explosives manufacturing facility in 1920 in Niewiadow and maintains its corporate headquarters in Warsaw, Poland, with primary industrial, testing, and production facilities located in Niewiadow. The enterprise operates across core business segments encompassing Ammunition Systems, Combat and Rocket Equipment, Drone Technologies, and Defense Engineering Services. Its product and service portfolio includes large- and medium-caliber artillery ammunition, notably 155 mm artillery projectiles and modular propellant charges; 40 mm grenade launcher ammunition produced under license from ST Engineering; recoilless anti-tank weapon systems, including the RPG-75M platform; unguided aviation rockets, including S-5 and S-8 calibers; anti-tank and anti-personnel landmines; explosive charges, pyrotechnic components, and defensive hand grenades; combat warheads and loitering munition payloads; precision artillery fuzes, including ZLT-50M models; unmanned aerial and ground vehicle systems; and specialized technical services, including explosive melting, pressing, filling, laboratory quality testing, ballistic range evaluation, and military hardware demilitarization. In recent strategic developments, the company executed a corporate consolidation integrating Polska Grupa Militarna S.A. with the industrial assets of Grupa Niewiadow and its operating subsidiary Zaklady Sprzetu Precyzyjnego Niewiadow Sp. z o.o., subsequently graduating from the NewConnect alternative market to the Main Market of the Warsaw Stock Exchange under the ticker GNS. To scale manufacturing output toward a targeted annual capacity of over 180,000 rounds of 155 mm artillery shells, the company secured growth financing from London-based investment fund Fidera, modernized its production lines at the Niewiadow industrial complex, and established major international and domestic strategic alliances. These partnerships include a framework agreement with United States-based Northrop Grumman for joint 155 mm shell casing and projectile production, a technology transfer agreement with KNDS France for LU211P artillery ammunition and Modular Charge Systems (MCS), and a joint development and commercialization initiative with the Polish Military Institute of Armament Technology (WITU) and PGO S.A.
