That's a very good point.
Building and maintaining domestic capacity is one of the big advantages of having these ships built domestically. However, the scope of my report is to estimate the cost of building these ships. It's not within the scope to determine the intangible benefits of having a domestic capacity to build these types of ships. The same goes for big Royal Canadian Navy procurements.
There are inherent national security benefits in having the capacity to build these ships domestically as opposed to building these ships abroad, but it's very difficult to quantify these in dollars.
