But then what platform are we launching them from?
A conventional submarine with the ability to launch a dozen or so would be useful capability, hence why I had hoped this might be scoped into the Collins refit. It could be a pretty potent strike platform. Both Japan and Korea have that kind of capability. Japan has a new sub launched strike missile, it might be worth looking at, but then you have integration costs.. Tomahawk is already compatible with the combat system.
Given the current shortage, I'm not sure the US could easily deliver Australia (and Australia integrate/Inservice) more than 200 in a timely way, Japan and other countries have orders too (400 for Japan).
Historically production was at ~90 a year. They are trying to ramp that to 1000 a year.
There are real concerns that now after the Iran strike that stocks are perhaps not as robust as they could be, particularly for a proper Sino-American conflict.
