I would love to see a 4th AWD or/and a 3rd LHD, but in reality we dont need to build either to have continuous work at Adelaide. All that is required is to bring forward the submarine project. We are going to have an increase in numbers, so why cant our submarine fleet grow prior to the end of Collins? If the third new submarine were to replace the decommissioning Collins, we would have a fleet of 8 subs until the final Collins was gone.
Too much like a good idea to have any chance of happening.
Collins will probably follow the example of so many other "replacement" defence projects, and either limp along or more likely cease to exist for a time until the new one - note -one takes up the capability again. To be followed at agonisingly snail like speed by 'some" others. We want 12, we plan for 8, we get 5 ---- you know how it works.
Here are some programs that follow the trend:
MRTT ..... existing aircraft gone - and being operated by someone else - still waiting for the replacements
Caribou - so long gone that a new generation of Australians doesn't even know what they were - still waiting for their replacements
Landing platform amphibious ships - what a mess
Fleet replenishment ships - ditto
etc etc
A real tale of woe...................
