Modification of the ships to operate the F-35B will enhance flexibility and expand the range of missions, with Yonhap quoting a source as saying that the South Korean military is looking at “maximizing the strategic value of the vessel’s capabilities.” The ships can carry several helicopters during normal operations, with the Izumo and Dokdo class designed to carry a maximum of 14 and 10 helicopters respectively.

Both ship classes will however need to be modified extensively internally and externally to operate the F-35B, including the application of a thermally protective coating on areas of the flight deck to withstand hot exhaust gases during F-35B vertical landings, and possibly even reshaping the flight deck to allow rolling takeoffs.

They will also need to have the ammunition magazines hardened and enlarged to accommodate the F-35B’s weapons, while aviation fuel storage facilities will also likely need to be expanded to account for higher fuel consumption compared to helicopters.
