Those subs are real topic for debate around HMC Dockyard Halifax. We should have just built our own. Just cam back from 6 weeks off Norfolk... Ive been to that USN base often and always amazes me at the sheer number of surface combatants they have....
We have 34 ships in all. 4 destroyers 12 frigates 2 replenishment auxillary vessels 4 submarines 12 coastal patrol vessels(the kind ill probably serve on in the naval reserve)
I belive were classed as a lower middle weight... Were small but were also have the the only foreign class of ship the USN will allow into a Carrier Battlegroup. 2 Classes, the 280s (Iroquois Class) and the CPF (Canadian Patrol Frigate)
