We need to understand why there are aircraft operating on Landing Assault ships like USS America. And why PLA Navy marine corps are vastly different from US Marine Corps.
1) Combat aircraft, fixed and rotor wings, operating from US Navy LHA are basically under command of US Marine Corps, NOT US Navy. In contrast, PLA Marine corps is a part of the PLA navy and PLA marines do not possesed any aircraft of their own.
2) Since US Marine Corps is a seperated branch from US Navy, their air wing operatiion doctrine is different from US Navy air wings on aircraft carriers. Primary mission of air wings on US Marine corps are to support the marine's expeditionary missions mainly involve amphibious assaults.
3) Unless there is a joint-service operation, US Marine corps use the LHA instead of Navy's aircraft carrier to transport their fighter jets. LHA like USS America are OPTIMIZED for the marine aircraft, basically F-35B, MV-22 and CH-53K, which are short or vertical take-off or landing. Basically it is like you mind your business, and I mind my business, between US navy and US Marine Corps. Such distinction does not exist in PLA Navy.
4) US Navy's air wings DO NOT operated from the LHA eventhough technically all LHA are under the US Navy's command.
5) Seperating manned combat jets and UCAV/UAV operating from aircraft carrier and type 076 may actually stream line the deck operations and logistic requirements. And with seperate set of operational protoco/procedure on aircraft carrier and the LHA Drone ship.
