Chinese navy requires both a heavy-duty helicopter and VTOL multirole fighter at the same time, they are not mutually exclusive in any way. Obviously the US isn't only one who consider these as light carriers. The most, if not all, of the LHDs are planned to accommodate deck fighters. The most striking and up-to-date examples are:
•Spanish Navantia's Athlas 26000 class (also known as Juan Carlos I class | 4 ships built, one planned and is being operated by 3 navies; Spain, Australia & Turkey)
•Italian Trieste is planned to accompany the sole light carrier of the nation, the Cavour
•Izumo class received the Cabinet approval to make necessary arrangements to convert into a proper light carrier (2 in service)
These nations does not have immediate plans to conduct amphibious operations across some ocean, far from home. A light carrier comes with a certain power projection capability which is aspired by the most. Furthermore, such capability would create a unique opportunity to strengthen the fleet formation via a 5th-gen fighter's astonishing sensor capabilities. If capable as an F-35B, some 3 fighters can provide some AEW capability, in absence of a proper one, on the unfamiliar seas.
