Maintain, operate, configure and upgrade the TSRCS and associated infrastructure in support of T&E requirements onboard the SDTS to support the Air Warfare Ship Self Defense Enterprise test requirements as well as surface ship combat system developmental test programs. Continue to work outstanding maintenance and repair efforts and complete necessary repairs to clear any outstanding DFS.

**FY2026 to FY2027 change.** Increase of $.976M from FY 2026 to FY 2027 due to OPTEMPO of SDTS in FY 2027. Increase from two (2) events planned in FY 2026 to six (6) events planned in FY 2027, projected to require increased HM&E maintenance costs to ensure safe operation of the SDTS.
