What do you like about this subject?  Submarines took up 17 years of my lfe. I was ships systems senior technician on a SSBN for 6 years, 'affectionately' known as WRECKER or OUTSIDE. Called other things of course at various times!! Best job in the world.
What do you still hope to achieve/learn in this field?  I have retired from the Royal Navy.
Something controversial or provocative about this subject  The crews are prepared to annihilate thousands of innocent people to protect their own way of life. I still accept this premise.
Something interesting about this subject that others may not know:  Missiles are ejected from a submarine by steam pressure. The rocket motor doesn't fire until it is clear of the water.
