## What project 5010 buys

AS(X) will conduct steady state and wartime sustained, forward-based tending, resupply, depot and intermediate level repair operations on submarines while anchored or pier side. In steady state, AS(X) will provide pier side support in a forward deployed submarine homeport, providing sustained repair, supply, weapons handling, and tending operations for submarines. AS(X) is being specifically designed to support deployed VIRGINIA class (VCS), COLUMBIA class (CLB) and future generation submarines in the 21st century. AS(X) is required to support all aspects of Intermediate level maintenance and support to deliver expeditionary tending operations to VCS block V (and later) submarines. The FY2026 budget for AS(X) Submarine Tender was zeroed out as part of the Congressional Mark for Reconciliation Funding Incongruence. FY2027 request for AS(X) Submarine Tender includes $90,092 thousand of discretionary funding and $0 thousand of mandatory funding for a total of $90,092 thousand.

**R-3 lines of work:** Product Development; Support; Test and Evaluation; Management Services.
