I saw a depiction of the Chinese LHA with one on the starboard side, but I now realize it was an older, inaccurate depiction. The only one you might consider that way is the aft elevator which allows an aircraft to extend back, over the edge there...sort of like the aft elevator on the Tarawa class, of which five were built andfrom the mid-1970s until 2015 when the last was decommissioned.
Here are some pictures of th Tarawa class LHA. It had a rear elevator like the CHinese vessel, but also had a deck edge elevator on the port side towards the aft. They were all replaced by the Wasp class.
Since that time the US has built 8 Wasp class LHDs and is now working on the 3rd America Class LHA, which will make 11 in total. It is not clear yet whether the US will maintain 11 or 12 of these vessels. I believe it may be 12.
The last two Tarawa class, the USS Nassau LHA-4 and the USS Peleliu, LHA-05, are being held in reserve.
