海军系统中先进的金属加工解决方案
Advanced Metalworking Solutions for Naval Systems That Go in Harm's WayThe U.S. Navy, like other Department of Defense services, is challenged to deliver needed capability in an austere budget environment. The Navy Manufacturing Technology Program (ManTech) plays a critical role in the Navy s ability to meet its affordability and performance challenges. The ManTech Program, including the Navy Metalworking Center (NMC), continues to execute an investment strategy that helps key acquisition Program Offices achieve their affordability goals. Our strategy includes the Virginia Class Submarine, DDG 51 Class destroyer, Littoral Combat Ship, CVN Class carrier, and the Joint Strike Fighter. NMC's projects, which are described more fully in this report, reduce total ownership cost by addressing acquisition and life-cycle affordability. For example the Plate Edge Preparation Improvements project is developing a solution for removing surface rust and pre-construction primer from large steel plates that will save up to $7 million on the cost of a modern surface combatant and is 300faster than the current process. Other projects like Main Propulsion Shaft Taper Inspection will save the naval shipyards $7.5 million in life-cycle refurbishment costs by eliminating the maintenance on gauges currently used and replacing them with white light scanning systems, reducing the labor to perform shaft inspections, and eliminating the need to purchase additional gauges for VCS and CVN.
