Dokdo-class

The Dokdo-class amphibious assault ship is a landing platform helicopter (LPH) class operated by the Republic of Korea Navy. Hanjin Heavy Industries designed and built the vessels to meet blue-water navy requirements and to support amphibious operations and military operations other than war. The class is planned to be succeeded by the CVX program.

The ships feature a well deck to accommodate amphibious assault vehicles and landing craft air cushion (LCAC) vessels. The design incorporates stealth technologies and supports an over-the-horizon assault concept, which utilizes high-speed air-cushioned vehicles and helicopters for landings. The flight deck is treated with urethane to support vertical take-off and landing aircraft. While the class has primarily operated land-based helicopters such as the UH-1H and UH-60P, development of an amphibious variant of the KAI Surion was initiated for ship-borne use. The second ship of the class, ROKS Marado, includes modifications such as a flight deck adapted for V-22 Osprey operations and different sensor suites and weapon systems compared to the lead vessel.

ROKS Dokdo was launched on 12 July 2005 and entered service on 3 July 2007. ROKS Marado was launched on 14 May 2018 and entered service on 28 June 2021. ROKS Dokdo provided assistance during search and rescue efforts following the sinking of ROKS Cheonan. In November 2024, the Republic of Korea Navy used ROKS Dokdo to test the Gray Eagle STOL unmanned aerial vehicle, which performed a take-off and a simulated landing procedure. The ships are also intended for roles in disaster relief and United Nations peacekeeping operations.
