About this IDV

Naval Sea Systems Command awarded an indefinite-delivery, indefinite-quantity contract to Epsilon Systems Solutions Inc., Mission Readiness Group Division, on March 15, 2021, with a ceiling of $841,014,199.07 for engineering and technical services to upgrade, repair, and maintain hull, mechanical, and electrical systems on Navy ships. This is a multiple-award vehicle with no set-aside designation.

Work is performed worldwide on various U.S. Navy ships, submarines, and shore facilities in CONUS and OCONUS locations. The contract supports Navy modernization programs across multiple ship classes and platforms, requiring contractors to maintain an approved quality management system and capability to work on diverse vessel types.

The originating solicitation, posted October 23, 2017, with proposals due March 5, 2018, sought engineering and support services aligned with NAICS codes 541330 and PSC codes R425 and R499. This is a follow-on to the Big Blue IDIQ MAC contract. The vehicle carries a five-year base period and five one-year options, with a potential maximum value of $300 million for other direct costs.
