This builder profile groups catalog entries where public sources identify General Dynamics Ordnance and Tactical Systems, GD-OTS, or OTS as a manufacturer, systems integrator, production source, or component supplier. The company is especially relevant to the catalog's U.S.-origin munitions records because its published portfolio spans air-delivered bomb bodies and penetrator components, 2.75-inch rockets, 30 mm ammunition, 120 mm mortar bodies, and 105 mm to 155 mm artillery ammunition.

GD-OTS describes itself as a global leader in the design, engineering, and production of munitions, energetics, weapons, armaments, and missile subsystems. Official and U.S. Army procurement sources also show the company tied to recent U.S. artillery-industrial-base expansion, including new 155 mm metal-parts capacity and load-assemble-pack capacity for modern 155 mm projectiles.
