Reports that the Chungnam-class frigate was mentioned for consideration in a new U.S. frigate competition have drawn attention to the identity of ROKS Chungnam and the actual stage of the program. However, based on the materials currently available, there is no basis to say that the United States has selected or ordered ROKS Chungnam or a Chungnam-class frigate, or that Hanwha Ocean has signed a contract to build U.S. Navy warships.
Key Developments
On August 13, 2026, the White House directed a review of using foreign designs and shipyards to expand U.S. Navy shipbuilding capacity. In a September 1, 2026 report, USNI News said that Japan’s Mogami class, South Korea’s Chungnam class, and Türkiye’s Istanbul class had been mentioned for consideration in a new U.S. frigate competition.
The key distinction is between being ‘under consideration’ and being selected or ordered.
Reports confirming that the Chungnam class was mentioned as a candidate have been identified, but no final U.S. government selection or contract announcement has been confirmed.
Current Status
ROKS Chungnam is the Republic of Korea Navy’s FFG-828 frigate and the lead ship of the Ulsan-class Batch-III. Official materials from the Defense Acquisition Program Administration describe Chungnam as a 3,600-ton next-generation frigate intended to replace existing Navy frigates and patrol corvettes. The ship was delivered to the Navy on December 18, 2024, and is operated as a Korean Navy vessel after undergoing the necessary force integration procedures.
Accordingly, the Chungnam identified in the currently available materials is a ship for the Republic of Korea Navy. This cannot be interpreted as confirmation that it has been incorporated into the U.S. Navy or approved for export to the United States.
Implications
Hanwha Ocean and Hanwha Systems completed their acquisition of Philly Shipyard in the United States in December 2024, securing a local shipbuilding base. This facility may draw attention as industrial context for the U.S. review of overseas warship construction, but the acquisition of Philly Shipyard itself does not mean that Hanwha has won a U.S. Navy warship contract.
The overseas construction model outlined in the White House memo is also conditional. It would initially allow up to two ships to be built at foreign shipyards, while subsequent ships would be built at U.S. shipyards. The model also calls for investment in the United States, workforce development, technology transfer, and supply-chain establishment.
The issue can be summarized as follows:
- Confirmed fact: The United States was directed to review shipbuilding options that include foreign designs and shipyards
- Reported: The Chungnam-class frigate was mentioned as a South Korean candidate
- Not yet confirmed: Final selection, an order, contract value, and production schedule
What to Watch Next
The next points to monitor are official announcements from the U.S. government or relevant agencies naming candidates, announcing a selection, or disclosing an order or contract. Until then, the safest description is that the Chungnam-class frigate was mentioned as being under consideration in a U.S. competition.
