Well, the subs were British: Lucas Electrics was probably involved somehow.
This story ran on CBC The National last night.
Seems that they have spent more that $3B maintaining
these to date. I guess they didn’t realize how expensive
keeping these boats really is. The reason for having them
is to assert sovreignity over the the Far North. They know that our boomer can hide out up there and they don’t like it and would like to be able to chase US subs out of there. Of course, theres no chance to do that without having nuke boats.
