This is a multiple-award IDIQ supporting non-complex emergent maintenance, continuous maintenance, and Commander Naval Operations availabilities on amphibious ships homeported in or visiting San Diego, California.

Work is performed at Southcoast's primary operational facility in San Diego. The originating solicitation (posted July 9, 2020, partial small business set-aside opportunity) sought suppliers for planned maintenance, continuous maintenance availability, emergent repairs, and facility work on amphibious transport dock ships, guided-missile destroyers, cruisers, and littoral combat ships homeported in San Diego and Norfolk.

The period of performance runs from the November 30, 2021 award through November 29, 2026. Southcoast Welding & Manufacturing, LLC, a Chula Vista, California-based structural steel and aluminum fabrication specialist, is an 8(a)-certified small business.

Recent delivery order activity under this IDIQ includes a $3.87 million firm fixed-price order (March 2, 2026) for USS Makin Island (LHD-8) FY26 Continuous Maintenance Availability level-of-effort reconciliation; a $1.91 million order (February 23, 2026) for USS Essex (LHD-2) FY26 continuous maintenance work; a $2.67 million order (December 1, 2025) for USS Anchorage (LPD-23) FY26 structural maintenance; and a $1.25 million order (December 1, 2025) for USS Ashland (LSD-48) FY26 continuous maintenance availability de-scoping. Delivery orders span fiscal years 2023 through 2026, with completion dates typically six to twelve months from issuance. The contractor has issued more than 192 delivery orders against this vehicle since award, generating combined potential value exceeding $205 million.
