The Department of Defense, through the Southwest Regional Maintenance Center, is seeking to add a new work item to an existing sole-source contract with National Steel and Shipbuilding Company (NASSCO) for the USS PINCKNEY (DDG-91) during its Fiscal Year 2022 Depot Modernization Period. This contract modification involves the replacement of the Bleed Air Hose Assembly, which is critical for maintaining the ship's operational capability prior to deployment. The justification for this sole-source action is based on the unique qualifications of NASSCO, as they are the only responsible source available within the current maintenance window, and bringing in another contractor would significantly disrupt the schedule and incur additional costs. Interested parties can contact Jonathon Mata at jonathon.f.mata.civ@us.navy.mil or Erik Lyons at erik.s.lyons.civ@us.navy.mil for further details regarding this procurement.
