Information : Weapons Proofing
CSTA is responsible for proofing, inspecting, reassembling, and shipping of all Army large caliber cannons. By performing the final quality assurance functions on these cannons, CSTA maintains the safety of the gun system.
CSTA receives large caliber gun tubes from Watervliet Arsenal and recoil mechanisms from the Rock Island Arsenal. These major subassemblies are then inspected, assembled, and proof tested. Proof testing consists of firing three standard rounds through the gun and then one "super slug." The standard rounds subject the cannon to typical stresses, while the super slug subjects the recoil to more severe stresses than normally experienced during its service life.
Once the cannon system is proofed, it is broken down, cleaned, and inspected. The gun tubes are cleaned in the traditional fashion, while the breech ring assembly and other small components are placed in a hot-water-based, high pressure parts washer. Inspection consists of both physical and magnetic particle inspection processes. Once the gun passes inspection, it is then prepared for shipment to its final destination.
