Not directly a QEC issue, but Flight Global has an interesting short analysis of the Japanese Izumo carriers.
"Fully loaded, the Izumo class ships displace 27,000 tonnes, which compares with 22,000 tonnes for the Royal Navy’s former Invincible class. The ships will reportedly carry about 10 F-35Bs in addition to helicopters and, possibly, the Bell Boeing V-22 Osprey, which Japan is also obtaining."
“There may be issues of having to provide extra workshop facilities, redesigning weapons magazines, and in particular providing all the necessary support for the F-35B’s considerable surveillance and reconnaissance capabilities,” says Childs. “Also adding further heat resistance to the flight deck. The Japanese may also have to decide whether or not they want to equip the Izumo class with a ski-jump ramp like the British, but unlike the Americans.”https://www.flightglobal.com/news/articles/analysis-izumo-and-kaga-aircraft-carriers-in-all-457571/
