HJ Shipbuilding Completes First U.S. Navy MRO Project, Eyes Follow-On Contracts

HJ Shipbuilding & Construction has finalized its inaugural maintenance, repair, and overhaul (MRO) project for the U.S. Navy, signaling a substantial progression in the company's ambition to penetrate the defense vessel maintenance sector. In a statement made on October 15, the South Korean shipbuilder confirmed that the USNS Amelia Earhart, a 40,000-ton-class U.S. Navy dry cargo and ammunition ship, had sailed away from their Yeongdo shipyard in Busan post-maintenance.

This milestone represents the maiden U.S. Navy MRO contract secured and finalized by a mid-sized South Korean shipbuilder, underscoring HJ Shipbuilding's capacity to adhere to stringent U.S. naval maintenance standards while managing intricate repair tasks. The company inked the maintenance deal with the U.S. Navy's Naval Supply Systems Command (NAVSUP) and Military Sealift Command (MSC) in December 2025.

The vessel was transported to HJ Shipbuilding's Busan shipyard in January 2026 for inspections and maintenance encompassing its hull, major systems, onboard equipment, facilities, and component replacements.

During the inspection process, HJ Shipbuilding unveiled supplementary maintenance prerequisites and defects that were not incorporated in the initial contract. The company proposed corrective actions, which the U.S. Navy then embraced, thereby significantly augmenting the project's scope. As a result, the project's timeline was extended from the originally scheduled completion in April to October.

HJ Shipbuilding affirmed they completed the additional maintenance work while maintaining close coordination with the U.S. Navy throughout the process. The supplementary work also elevated the contract value, generating additional revenue prospects for the shipbuilder.

Although the company refrained from disclosing the revised contract amount, the scope expansion illustrated its ability to adapt to evolving maintenance needs while upholding quality and project management standards. The successful completion is anticipated to bolster HJ Shipbuilding's pursuits to secure additional U.S. Navy MRO contracts. The U.S. Navy expressed contentment with the quality and completeness of the work, acknowledging its technical acumen and contract execution performance.

Industry analysts perceive the project as a significant milestone for South Korea's mid-sized shipbuilding sector, which has historically concentrated on commercial vessel construction and repair. Entering the U.S. naval maintenance market could offer opportunities to diversify income streams and optimize existing shipyard infrastructure and engineering expertise.

The demand for naval MRO services is also garnering attention, as the United States strives to bolster maintenance capacities across the Indo-Pacific region. South Korean shipyards could capitalize on their geographical proximity, established ship repair capabilities, and experience managing large vessels. However, securing recurrent contracts will hinge on persistently meeting U.S. Navy standards, upholding competitive turnaround times, and showcasing dependable performance across subsequent projects.
