Korea Steel

Korea Steel, a South Korean for-profit corporation based in Gimhae, Gyeongsangnam-do, operates as a subcontractor (94% of recent awards) and occasional direct supplier to the U.S. Navy, delivering specialized marine hardware and ship construction materials to support vessel repair and new-construction programs. The company competes full-and-open with no small business set-aside posture.

Korea Steel's federal footprint is narrowly concentrated with the Department of the Navy. Naval Sea Systems Command accounts for 29 of 31 recent awards, all in a subcontractor role under National Steel and Shipbuilding Company (NASSCO), the prime contractor for tanker (T-AO class) construction and modernization work. Korea Steel supplies specified and non-specified materials, pipe, and detail design and construction support for the T-AO 205, T-AO 206, T-AO 207, and T-AO 209 programs. The remaining two awards, both direct prime purchases, come from Military Sealift Command: a $287,350 purchase order for a watertight sliding door on the USNS Lucy Stone and a $287,350 purchase order for a watertight door on the USNS Robert F Kennedy, both dated June 2026 and with completion required by January 2027. These two orders represent the only transparency into Korea Steel's pricing at the prime level; the NASSCO sub awards carry no visible dollar values in the source, though their combined obligated amount ($79.3 million across 29 subs) indicates substantially larger individual sub-awards than the published potential values suggest.

Activity accelerated sharply in 2024, when 24 awards were placed, compared to one award in 2023 and four in 2025. Two awards (combined potential value $575 thousand) face completion inside the next twenty-four months. The vendor's NAICS concentration splits between Ship Building and Repairing (29 awards) and Metal Window and Door Manufacturing (2 awards); PSC coding flags Marine Hardware and Hull Items for the two Military Sealift Command orders. Performance occurs in South Korea, which is typical for offshore marine component and material supply chains. Korea Steel's role is exclusively as a materials and hardware supplier and design-support sub to NASSCO on major Navy tanker programs, with limited direct Navy prime exposure and no demonstrated capability or vehicle presence outside ship construction and repair.
