I was on a boomer. Our job was hiding with missiles, although we had the ability to protect ourselves if attacked. Fast attack subs have capabilities that are way above our pay grade. Having special forces, expert scuba divers and weapons, their abilities are beyond your imagination.
One of my friends was a top dog at Mare Island re converting Boomers to do what you pointed out.
That was a long time ago! We can only imagine what our converted Boomers can do, under water, on top of the water and in the air/space with their missile power.
