If you say so.
Both of these yards just seem to be small in scale when compared to Saint Johns Shipyard and Davie. They are barely going to be turning out 1 ship per year each. The timeline to complete 15 CSC is 16+ years once they cut steel on the first ship. It looks as though Irving can only work on 2 ships at a time, as demonstrated by the fact the the 3rd AOPS only had steel cut once the 1st AOPS was completely assembled (though not dropped in the water). I'm willing to bet the Seaspan won't have the space to be working jointly on the new JSS (which won't have steel cut on them for what, another 4yrs?) ships, but will have to substantially complete one before steel can be cut on the other.
If I dare to look out to the 2032 time frame, its safe to say the Irving won't have a chance in global warmed hell in winning any bid to replace our 4 subs (if we do decide to continue to have subs....) as they'll only be halfway done (maybe, hopefully, fingers crossed) the build out of the 15 CSC's. That effectively means the Seaspan will get this contract by default - unless Davie manages to holdout another 15yrs doing odds and sods jobs - but will Seaspan even have this capacity to do so as they'll be just starting the build of the icebreaker they've been promised, let along the 10 coastal defense ships that they are supposed to build..... So, who builds the subs in the 2032-34 time frame......
