Canada's last working sub?

Interestingly, old diesel submarines can be harder to detect than modern nuclear submarines. The reason being that a diesal sub can turn off all of its machinery and run completely silently off of batteries. A nuclear sub can never shut off its reactor and as such can never completely eliminate its noise signature.

In some situations low-tech is better.

Could explain why the US is training vs Swedish diesel subs (with Swedish crew, rented ). Seems to be needed according to what has been mentioned here.

From what I understand, diesel subs are excellent for coastal defense. The battery power can keep them going silently, and range is not really an issue when hugging a coastline. Also, if they get sunk on a coastline, you don't have a radioactive mess washing onto your beaches.

I think the North Koreans have lots of diesel subs. The US Navy probably needs practice to counter them, since they don't have any of their own.
