France and Italy used that arrangement since the 60s without many problems (among others on the Jeanne d'Arc and Vittorio Veneto helicopter cruisers).I did notice interestingly that the hanger deck was reached from the flight deck via a lift, didn't the US try that arrangement and had lots of issues?
The 8,800-ton Vittorio Veneto, especially post-modernization, in fact shows some more similarity in the heavy, layered air defense system (with SM1-ER long-range SAMs and eight 76mm guns and three 40mm CIWS as close-in defense).
