Re: Brazil might get nuclear-powered submarines even before Australia
#2What are the benefits of a nuclear submarine force for Australia (Or Brazil for that matter)? Maintenance and operating costs are much higher, nuclear subs are less stealthy, and the primary benefit of long-term 'anywhere' nuclear deterrence is irrelevant for a non-nuclear force like Australia.
As I understand it, the Australian Navy patrols a relatively small portion of the ocean near their home continent. Do they have any reason at all to need three-month patrol capability?

> Maintenance and operating costs are much higher, nuclear subs are noisier
Diesel-electrics submerged are quieter for a short time at any significant speed, or a couple days at very low speed, while nuclear subs are nearly as quiet, at speed, for much longer, without a tactical time/speed tradeoff. This is why pretty much everyone who can afford them uses nuclear attack subs in preference to diesel-electrics.
A I understand it, one important consideration is, if you might want to shadow targets during a crisis because orders might come in to take them out, you need to be able to do extended quiet operations without compromising speed to make that work.
