| Source measurement | — | Globalsecurity.org suggests a maximum capacity of 18-24 H-60 class helicopters, or a smaller number of larger helicopters, even though the official complement was reported as three Mitsubishi H-60 and one AgustaWestland AW101 helicopters, or three Mitsubishi H-60 and one Sikorsky CH-53 Sea Stallion helicopters. The ships have also operated JGSDF Fuji AH-64D Apache attack helicopters during joint amphibious exercises with the United States. It is speculated that future modifications may allow the operation of VTOL / STOVL fixed-wing aircraft , such as Harriers or F-35 Lightning II .[source]Hyūga-class helicopter destroyer · Design and specifications; only the objects and conditions stated in this passage In November 2009, Hyūga participated in "Annualex 21G" joint naval exercise with the US aircraft carrier USS George Washington and other USN and JMSDF ships to maintain the interoperability between the two navies.[source]Hyūga-class helicopter destroyer · Ships in the class; only the objects and conditions stated in this passage |
