US Navy Sends Ammunition Ship USNS Alan Shepard to Vigor Marine for $13.8M Mid-Term Maintenance

Military Sealift Command awarded Vigor Marine a $13.8 million firm-fixed-price contract for a 50-day mid-term maintenance availability on USNS Alan Shepard, a Lewis and Clark-class dry cargo and ammunition ship. The work is scheduled at Vigor's Portland, Oregon, yard from December 1, 2026, to January 19, 2027, with three unexercised options potentially lifting the total to about $14.15 million. The auxiliary vessel supports at-sea replenishment of US Navy carrier and amphibious groups with stores, equipment and ammunition. This award covers planned ship maintenance, not construction of a replacement vessel or an additional operational deployment.
