Detyens Shipyards Inc.

Detyens Shipyards Inc., a small business Subchapter S corporation based in North Charleston, South Carolina, provides ship repair, drydocking, maintenance, and modernization services to federal maritime agencies as a prime contractor (100% of recent awards), with no subcontractor relationships. The vendor operates the largest commercial shipyard on the U.S. East Coast and holds NAICS 336611 (Ship Building and Repairing) as its primary classification, serving federal customers across PSC codes dominated by ship maintenance and repair (H228, J998).

Customer concentration sits overwhelmingly with the Department of the Navy's Military Sealift Command, which accounts for approximately 68% of Detyens' federal exposure—158 awards valued at $1.79 billion in combined potential value out of the vendor's $2.62 billion total portfolio across 1,375 awards. The Department of Homeland Security's U.S. Coast Guard is the second-largest customer with 40 awards worth $203.1 million, followed by the Department of Commerce's National Oceanic and Atmospheric Administration with 45 awards worth $91 million. Together, these three customers cover 93% of the combined potential value across the vendor's named customer base. Recent representative work includes a $70.4 million Military Sealift Command definitive contract awarded March 5, 2025, for lay berth, regular overhaul, and dry-docking of the USNS Lewis and Clark (T-AKE 1) with ultimate completion by October 30, 2026; a $26.5 million Coast Guard delivery order issued July 1, 2026, for heavy depot maintenance and drydocking of WMSL-class cutters; and a $52.9 million Military Sealift Command definitive contract from March 13, 2026, for regular overhaul and dry-docking of the USNS SUPPLY (T-AOE 6).

Detyens holds position on five major Navy indefinite delivery contracts that anchor most of its task-order volume. The top three vehicles by task-order count are Indefinite Delivery Contract N0002485H8139 (229 task orders), Basic Ordering Agreement N6267382C0001 (200 task orders), and Indefinite Delivery Contract N6267370C0002 (149 task orders). The vendor also holds a five-year single-award Coast Guard IDIQ awarded July 1, 2026, with a ceiling of $119,815,501.25 through June 30, 2031, for drydock and heavy-maintenance repairs to 418-foot WMSL-class cutters at its Charleston facility. The vast majority of Detyens' awards carry total small business set-aside designations, reflecting its small business posture.

Activity has remained relatively stable over the past five years—13 awards in 2022, 9 in 2023, 10 in 2024, 15 in 2025, and 13 in the first ten months of 2026—with seven awards valued at $195.3 million in combined potential value reaching ultimate completion within the next twenty-four months and therefore exposing the vendor to recompete risk in that window. Service Contract Inventory data shows SCI-reportable invoiced revenue of $396.1 million across FY2022–FY2025, with 347 FTEs delivered in FY2025 on seven prime service contracts. Government-paid hourly rates on Detyens' prime service contracts run a median of $205.28 per hour, with senior labor pricing through $265.19 per hour at the 90th percentile. The vendor self-performs all reported work across SCI-reportable prime contracts with zero subcontractor-hours engagement, reflecting a vertically integrated delivery model. Detyens also received a $566,617 Project Grant from the Maritime Administration under the Assistance to Small Shipyards program (CFDA 20.814) awarded July 21, 2022, for replacement of diesel-powered fire pumps with electric-powered ones at its Charleston facility, with completion targeted for July 29, 2024. Three recent sub-award records show minimal subcontractor volume: work as a named sub to Vector Planning & Services LLC on Coast Guard C5I systems engineering (December 2025), to Oceanetics Inc. on vessel repair task orders (January 2025), and to BAE Systems Land & Armaments L.P. on guided missile launching system engineering support (July 2024).
