Costs of Submarine Maintenance at Public and Private Shipyards
Abstract
Public shipyards conduct a large majority of all submarine maintenance. Those shipyards are Navy-owned and -operated, but the Navy has been experiencing long delayssometimes as much as several yearsto obtain maintenance on its submarines at those shipyards. As a result, some submarines have missed deployments or had shortened deployments. The Navy has sent several submarines to private shipyards for overhauls in recent years but could send more. This report compares the costs of submarine maintenance at public and private shipyards. This analysis focuses on depot maintenancespecifically, Docking Selected Restricted Availability (DSRA) overhauls for the Navys Los Angeles class attack submarines (SSN-688s). DSRAs are medium-sized maintenance events that last several months and occur every four to six years over the 33-year lifetime of an SSN-688 submarine. They include maintenance, repairs, and upgrades; the submarine is put into a dry dock to enable work on the hull, propulsion, and systems (which would otherwise be underwater).
