They've already pumped hundreds of millions of dollars into updating these barely functional 30 year old subs. $2.5 billion gives them another 15-20 years (they say). I hope the Liberals know what they are doing. If they are right, it could be a bargain. If wrong, a costly mistake!!! 

I think they should focus on replacing maritime patrol aircraft fleet. We have the longest coastline in the world by a long stretch. 
 Scrap the subs.
