True..... not all force must be projected across the world.
Some of our sub fleet would be close to home. and we could produce a large number of these at a much-reduced cost with very little loss in effectiveness...
Not sure if we still operate diesel boats, I have worked them, 6 men died on the last one I was on when the batterys exploded. I was not onboard but some of my shipmates were.
Oh the smell of diesel and amine....
