Kollmorgen Corp., Northampton, MA received a $9.9 million fixed-priced, not-to-exceed modification to previously awarded contract (N00024-02-C-4032) for MK 46 Optical Sight System (OSS) Provisioned Item Order (PIO) spare assemblies, subcomponents and kits. The OSS is an integral component of the MK34 naval gun, which includes the 5″ MK45 Gun Mount and the MK 160 Gun Computer System. The primary function of the OSS is to provide a safety-check sight to allow the gun operator to determine safe firing zones during gun operation. It is also used for gun targeting and target identification. The Mk46 OSS is found on DDG-51 Destroyers, United States Coast Guard Cutters and FMS Naval Ships.
Work will be performed in Northampton, MA and is expected to be complete by September 2006. This modification combines support of the U.S. Navy (96%), as well as the Governments of Japan (2.5%) and Korea (1.5%) under the foreign military sales program. The Naval Sea Systems Command, Washington, DC issued the contract.
