About this file
This document is a Liaison Action Record (LAR) for a Bath Iron Works Planning Yard (BIW PY) contract related to a Split Riser modification for a SATCOM Rack on DDG-105. The LAR addresses an issue with a technical drawing (DWG 180-8942078A) that lacks specific installation location and material details for the Split Riser. The document involves multiple Navy organizations including NAVWAR, NIWC, PEO C4I, and various shipyard and support centers, with a distribution list of over 40 recipients.
The LAR, dated September 11, 2025, details a technical communication requesting concurrence to install an aluminum 4"x6" Split Riser behind the SATCOM Rack on the False Deck for new cable routing. Bath Iron Works Planning Yard concurred with the issue, indicating a material impact that will require procurement. The document is marked with Distribution Statement D, limiting distribution to DoD and U.S. DoD contractors, and contains a warning about technical data export restrictions under the Arms Export Control Act.
