I think timing is important. Now that we have F-35's in our hands, and operational and procurement costs are knowns and getting cheaper, with less and less operational issues cropping up, the F-35B is actually operational, and our LHD's are also proven, the time to seriously ask the question and address what it would require is getting closer. Probably a 3 year window. But you really have to formulate capability requirement, before you go shopping for platforms. Back when we were talking about the old fortress Australia and continental defence, a carrier was not needed. We had long range strike platforms and clear technological superiority over everyone in the region. If we are talking about being a full spectrum key security partner for a dozen major nations, and being the primary security for half a dozen nations, that are directly facing expeditionary heat from a rising power as well as being a moderation force and a buffering power between two polarising super powers. Then you would probably need significant carrier capability, based over multiple ships, supported by extensive land based capability. (among other things). If I was Spain I would moving heaven and earth that the AOR's comes under budget and early. I assume Turkeys LHD has all the F-35B modifications installed, and is probably most likely to be the first of class to operate with the F-35. Sometime around 2021. I hope Spain can find some money to resurface their ship before then. Would be great to have proven F-35B operations off the platform, before 2021. As for moving M1A2.. we don't need to amphibiously land them that often. Realistically, landing two Boxers would be much more useful (and around the same weight). Boxers would be deployed in nearly every amphibious deployment. So carrying two in a landing craft is a tremendous benefit. For intra-theatre lift I think there is still a need for something more autonomous and ocean capable than even the MSVL. Something like the Damen LST-120 might fit in as an order after the OPV's as a multirole ship. Batch of 2-3. Built in WA.
