Could modern LHD or LHA amphibious ships remain useful as escort carriers for convoys or lower-intensity theatres?
Short answerYes, if enough hulls are available after amphibious priorities are met; in that situation their flight decks can provide escort-carrier capability.
NotesThe role depends on fleet availability rather than a rigid ship label. An LHD or LHA is normally valuable for amphibious operations, and that primary mission may consume every available hull. If a navy has enough of them and urgently needs aviation for convoy escort or a lower-intensity theatre, the same flight deck can fill an escort-carrier role. Force structure and competing commitments determine what a flexible ship actually does in war.
