About this opportunity
The Department of the Navy Naval Sea Systems Command issued a Justification and Approval for sole-source contract modification to National Steel and Shipbuilding Company (NASSCO) on March 9, 2026, to perform a TACLOG HVAC Upgrade (Work Item 512-11-004) aboard the USS HARPERS FERRY (LSD 49) during FY25 Selected Restricted Availability. The upgrade is necessary to address critical operational requirements, as newly installed Intelligence Carry-On Program (ICOP) equipment generates excessive heat that would overheat critical electronic systems without the HVAC enhancement before the vessel's deployment. The sole-source justification was based on strict scheduling constraints, as a competitive procurement would consume over 40 percent of the remaining five-month schedule for mobilization and would delay the ship's operational commitments; NASSCO was determined to be the only responsible source capable of executing the work within the required timeline while maintaining continuity with ongoing shipyard operations. The contract modification adds this work to existing firm-fixed-price contract N00024-25-C-4422, with work completion required by the C5ILO milestone on August 10, 2026, and delivery by October 16, 2026, though the estimated total value is redacted in the justification document. Funding for this modification is provided through FY25 OPN, with costs managed by TYCOM.
