Improving the manufacturability and installation of weapons magazine C-channels will reduce labor and cost. Newport News Shipbuilding photo
The Navy Metalworking Center (NMC) is leading a Navy ManTech project to improve a labor-intensive process involved in the manufacture and installation of the universal Weapons Magazine Tie-down System (WMTDS) on Navy platforms.
Installation of the deck channel (C-channel) involves considerable welding, grinding, leveling, and surface preparation. The legacy welding procedure induces channel distortion that requires rework. In addition, the C-channels are difficult to access when applying surface coating after they have been installed.
The Integrated Project Team (IPT) will examine both Newport News Shipbuilding (NNS) and Ingalls Shipbuilding (Ingalls) installation processes, explore manufacturing and installation process improvements, and consider alternative component materials and designs to improve installation and quality, as well as to reduce rework. The IPT will develop and evaluate several concepts and construct prototypes to validate the process improvements.
This project will reduce the overall installation hours and the associated cost to manufacture and install the WMTDS. The estimated cost savings for this project are $5.5 million over a five-year period on CVN 80; LHA 7 and LHA 8; and Ingalls-built DDG 51 class ships. In addition to cost savings, the improved universal WMTDS solution is expected to improve first-time quality and final preservation (surface coating). Finally, this project will result in a standardized installation approach for a cross-platform solution.
This project’s results are expected to be implemented in the fourth quarter of fiscal year 2017 on LHA 8 at Ingalls and in the third quarter of fiscal year 2019 on CVN 80 at NNS.
