The Canadians were never going to use the submarine anyway, so why bother? For that matter, why not just get a rowboat and paint the word SUBMARINE on it in large block type?
Hey, neat idea! And, they could probably get a deal on an aircraft carrier on which they could just paint ''Aircraft Carrier''. France might make Martin a heck of a good price.
And they could have drills where ''Submarine'' chases ''Aircraft Carrier'' around... well, assuming they can find enough oarsmen for both ''ships''.
