It will most likely be as it currently is.
There are 12 surface combatants(10 operating) but only 4 have a helo embarked. When a ship sails for MEAO they embark a flight, while 1 returned, 1 preparing for deployment and another frigate heading either SEAD or USA, so they take a flight with them. When we had the LPAs running, they only took a flight when heading overseas or on excercise, and these we mostly Sea king in any case. Success hasnt carried a flight for a while and with what im hearing, wont be going anywhere to require one. And sirius of course can not carry one.
With 24 MH60s these will be spread across the 8ANZACs as 4 with helos, 1 AWD will have a flight unless fleet places a greater emphasis on ASW so maybe 2(its a lot better without a flight as more room onboard and less egos...
) and the LHDs will carry maybe one seahawk for S&R as the rest will be MH90, with the majority coming out of Army Air wings.
Theres also the future training helo to be worked out, whether or not we stay with the A109 or something else, and these would be alot better operating off from the minor war vessels as theres less flight team required and will provide a greater range and survellance for patrols up north as well as S&R for the boats and any other emergenices which may arrive.
