Three subs, whether used or not, don't seem enough to provide an effective defence, even if we eventually get them. You could barely maintain one consistently on station. I assume we're hoping the US will locate some of theirs here once we've built the necessary facilities. On the other hand the AUKUS design, if it ever gets built, is massive and will take years to get all the bugs ironed out of it. We'll probably be the ones stuck with doing most of the testing. Being designed jointly between Australia, the UK and the US it will probably not suit anyone. Reminds me of an old joke about what a camel is - a horse designed by a committee.
