## What project 2924 buys

This project provides for labor and engineering support, preventive and corrective maintenance of mission critical Hull, Mechanical and Electrical (HM&E) and remote-control system maintenance aboard the Self Defense Test Ship (SDTS) in support of the Navy RDT&E of ship self-defense systems. Testing aboard this ship provides the capability to safely test self-defense weapon systems within their minimum range and reduces the number of fleet units required to support RDT&E efforts. Funds are used to purchase consumable supplies and repair parts, conduct routine preventive and emergent corrective maintenance and engineering support services and the necessary personnel to support at-sea operations.
