The Scranton Army Ammunition Plant is a Joint Munitions Command installation at 156 Cedar Avenue in Scranton, Pennsylvania. Army and GD-OTS sources describe it as a government-owned, contractor-operated plant whose operating contractor is General Dynamics Ordnance and Tactical Systems. Its public role is metal-parts manufacturing: billets are forged, nosed, heat-treated, machined, welded, phosphated, painted, inspected, and tested before projectile bodies move into the wider ammunition supply chain.

The site has a long industrial history. Joint Munitions Command says the buildings began as a 1908 steam-locomotive erecting and repair facility, SCAAP was established in 1953, U.S. Hoffman Machinery operated it until 1963, Chamberlain Manufacturing followed, and General Dynamics Ordnance and Tactical Systems assumed operation in 2006. GD-OTS states that Scranton Operations has remained in continuous production of weapon-system metal parts since 1963 and has delivered more than 26 million projectile and mortar metal parts.

For current ammunition context, the plant is especially relevant to 155 mm production. GD-OTS describes Scranton Operations as producing artillery shells for 105 mm to 155 mm applications and lists M795 and M107 155 mm high-explosive projectile metal parts among products shown on its Scranton Operations page. U.S. Army reporting in 2026 said SCAAP manufactures large-caliber metal projectiles and was undergoing major modernization to expand 155 mm shell production capacity.
