Are there reasons why SM2 could not be fitted to the ANZAC's tactical length Mk41 VLS? Or perhaps post-AMCAP fit-out when CEAFAR2-L is fitted?
Size and weight wise appears feasible (SM2 weight
708kg versus quad packed ESSM at 1,120kg). (Individual ESSM weight
280kg).
Potential loadouts: 8x SM2 or 6x SM2 + 8x ESSM etc. Granted probably not the most ideal loadout for such a deployment so may need a second ANZAC on standby or already in-theatre to relieve the first ANZAC if they deplete their inventory, which may be able to restock at a nearby friendly naval port facility "relatively' quickly (assuming arrangements to do so are put in place). And the RAN would be operating with other allied assets to share the tasking so re-arming may be able to be factored in.
The RAN has a highly capable medium(?) Frigate compared to many even well resourced nations and surely having some extra flexibility with its (limited) VLS cells may be a useful and inexpensive capability addition for these challenging times until the replacement Hunters are ready?
