Detyens Shipyards has been awarded a $20.5 million firm-fixed-price contract by [Military Sealift Command](https://akta.pro/company-profiles/003hx6r/military-sealift-command) for a regular overhaul and drydocking of the fleet replenishment oiler USNS Leroy Grumman, [Pulse 2.0](https://pulse2.com/detyens-shipyards-awarded-20-5-million-contract-for-usns-leroy-grumman-overhaul-and-drydocking/) reported on November 2, 2026. The work covers a 152-calendar-day shipyard availability in North Charleston, South Carolina.

## Inside the Leroy Grumman Availability

The contract includes a base work package and four unexercised options for additional work and time. If all options are exercised, the cumulative value would rise to approximately $23.2 million. Work begins January 20, 2027, and the overhaul is expected to be completed by June 20, 2027.

Military Sealift Command obligated the full $20.5 million base amount using fiscal 2027 Navy operations and maintenance funding, which expires at the end of the fiscal year. The procurement was a small-business set-aside solicited through the government-wide Point of Entry website, and four offers were received. Military Sealift Command in Norfolk, Virginia, is the contracting activity under contract N3220527C0012.

USNS Leroy Grumman is a fleet replenishment oiler that delivers fuel and other supplies to Navy ships at sea to sustain extended operations. Regular overhaul and drydocking periods let Military Sealift Command complete maintenance that cannot be efficiently performed while the vessel remains operational, including hull inspections, mechanical repairs, system maintenance and preservation. The option structure lets the command authorize additional work if inspections identify further requirements or the availability needs to be extended.
