We can't afford to accelerate the frigate and submarine programs, to do so would be to repeat the mistakes of the past and return to the boom or bust cycles of the past, with its black holes, block obsolescence, and waste.
Ideally the OPCs would have followed the ANZACs out of Williamstown, followed in turn by the DDG replacements, FFG replacements and then full circle, the ANZAC replacement. The only stuff up we would have had to persist with would be the FFGUP as without that there would have been an unacceptable capability gap, unless of course we bought the four Kidd class DDGs and ran the four best FFGs on unmodified.
Instead we had black holes, expensively upgraded and developed facilities left dorment or shut down, work forces run down, then greenfield sites developed and work forces created from scratch less than a decade later at great expense, only for the process to be repeated.
We now have a national ship building plan, we just need to stick to it.
