Re the subs I agree. The UK purpose built those subs as test platforms to reduce crew size in their nuclear subs. Never intended for actual use, and Canada should have known this was a poor bargain. The Eurofighter Typhoon is different, a mature aircraft matter and in some ways more capable than a Super Hornet, or especially worn out FA/18's from a generation older that Australia is intending to dump after it receives its F35's!
