Improving the manufacturability and installation of weapons magazine C-channels will reduce labor and costs.
S2582 Improved Weapons Magazine C-Channel
This Navy Metalworking Center (NMC) project improved a labor-intensive process involved in the manufacture and installation of the Universal Weapons Magazine Tie-down System (WMTDS) on Navy platforms. Installing the deck channel (C-channel) involves considerable grinding, leveling, welding, and surface preparation. In addition, access is difficult when applying surface coating to the C-channels. This project reduced the overall installation hours and the associated costs to install the WMTDS through improved manufacturing and installation processes.
The Integrated Project Team (IPT) developed and evaluated several WMTDS concepts that targeted changes to channel spacing and tolerancing, channel alignment fixtures, and improvements to grinding and painting. An automated welding system and revised primer system were also investigated for future implementation. The IPT analyzed the selected improvements to ensure compliance with the structural system requirements, and constructed and evaluated prototype(s) to validate the process improvements.
Implementation and Technology Transfer:
Early implementation of the spacing, tolerancing, and other process improvements began in July 2015 on LHA 7 at Ingalls. A request for contract modification is pending at NNS for spacing and tolerancing changes; spacing changes are not likely on CVN 79, but are expected on CVN 80 as initially planned. The implementation target date for C-channel improvements is the fourth quarter of FY17 on LHA 8 at Ingalls and the third quarter of FY19 on CVN 80 at NNS.
