Something I keep coming back to with surface combatants is since WWII we seem always end up with about a dozen irrespective of cruisers, carriers, submarines, strategic requirements, crew sizes etc. we seem to always remain at that figure.
There is a chance, if the FFGs are not life extended and only six FFs are ordered to replace the ANZACs, that the total number of combatants may drop to nine. Probably fair enough if submarine numbers were being increased to twelve but that's highly unlikely now. Could be argued that the LHDs are very big and add to capability but the thing is they are not combatants and need to be escorted to in actual fact, all else remaining the same required an increase in combatant numbers not a reduction.
Looking outside the square if we can order OPVs to replace the PBs that will take some of the load of the majors that are currently required to supplement the BPC efforts where the PBs are not up to scratch. Take it a step further and acquire a class of light frigates similar to the new South Korean Inchon Class

or the Turkish MILGEM to slot in between the OPVs and majors and they could cover off many of the RANs international obligations far more affordably than the current FFG and ANZAC deployments. Such a ship could be locally design and built and use systems from the ANZACs such as the VLS, 5" Gun, torpedos etc. as well as ensuring it can operate MH-60R (and S
) as well as Firescout etc. The OPVs would ideally share a common hull with the MCM and Hydrographic vessels, whether going for the OCV concept of the previous government or simply progressively replacing like for like using common hull and systems to ensure savings in logistics and training.
This leaves the question of what to do with the majors, the AWDs (we really should start calling them DDGs) form part of that but what to do with the rest? Do we order six (Smith), eight (Rudd), or nine (common sense) new generation GP frigates with high end ASW, air defence and land attack capability or do we look outside the square and go for something different to address the elephant in the room, China. Half a dozen Type 26, FREMM, something indigenous or something cheap and nasty, like fore like?
My thinking is how about we go to the USN and ask how much for three repeat DDG 1002 (steel superstructure fully sorted systems) but with Dual Band Radar as fitted to Gerald R Ford and then go to Japan and ask how much for three repeat Izumo Class DDHs but also fitted with Dual Band Radar. Also look at fitting both classes with AUSPAR in place of DBR. This would more than cover he RANs ASW, land attack and air defence requirements, allowing the formation of three identical task groups to escort the LHDs or participate in international or national operations. Throw in a couple of the light frigate of the OPV based MCMs or survey vessels or even a couple of the LCH replacements as required and you have a flexible task groups that can be tailored as required.
The DDG1002s could be specified with SM-3 and maybe additional VLS in place of the 155mm in "B" position and the Izumo could be equipped with a variety of helos and UCAVs to suit the mission. MH-60 R&S would be a no brainer with Tigers, MRH90 and Chinooks also in the mix but EH101 and Osprey could also be options. A mix that would make sense would be a sqn of ASW helos and detachments of AEW, CSAR, Utility / Assault and MCM helos, as well as UCAVs.
On the LCH replacement an idea that comes to mind is an OPV based APD with a well dock or a ramp premising the launch and recovery of an LCU or a LCM1E and or CB90 type Assault boats with a vehicle deck accessed from the rear ramp but also from side ramps.
