South Korea to Replace F-35Bs with Drones on Future Aircraft Carriers

South Korea has revised its plan to build a light aircraft carrier, opting to forgo the acquisition of F-35B fighter jets in favor of deploying domestically developed drones, according to the Chosun newspaper.

The updated concept reflects a shift in strategic priorities and a push for greater autonomy in defense technologies.
Instead of U.S.-made F-35B short takeoff and vertical landing jets, the carrier will be equipped with South Korean-made unmanned aerial vehicles.

The decision is also driven by financial considerations, as both the procurement and maintenance of F-35Bs are costly.

By replacing manned fighters with UAVs, the Navy aims to reduce dependency on foreign imports and promote domestic defense capabilities.

UAVs are expected to provide a more cost-effective means of carrying out reconnaissance, surveillance, and strike missions.

The original plan, launched under former President Moon Jae-in as part of the “Multi-Purpose Large Landing Craft II” program, called for the construction of a 30,000-ton light aircraft carrier measuring 260 meters in length and 40 meters in width by 2033. That design included 20 F-35B fighters.

Under the new plan, the carrier will deploy a mix of combat, reconnaissance, and loitering munitions (kamikaze drones), while retaining some manned rotary-wing aircraft for landing and attack missions.

Navy officials explained advances in unmanned systems and evolving operational requirements at sea as key reasons for the change. The vessel is envisioned as a command ship for mobile forces, capable of executing strike, amphibious, security, and search-and-rescue operations.

Cost savings are also a major factor. The original project was expected to cost ₩7 trillion (approximately $5.1 billion), while the revised UAV-based design is projected to reduce costs by several trillion South Korean won.

Last month, the Navy commissioned HD Hyundai to develop the new ship concept. Final approval of the revised plan is expected after a staff meeting in late May. If adopted by the end of the year, construction could begin in the second half of the 2030s.
