My favorite submarine, or Navy submarine, would have to be the USS Nautilus. It is one of my favorites because it broke the rules for submarine warfare. The USS Nautilus was the first nuclear-powered submarine. Not only was it a ground-breaking modern marvel, but it was also a strategic resource. The Navy could now swiftly move under the depths of the ocean to wherever it wanted, whenever it wanted, and however long it wanted with no refueling. At the time the powering of maritime vessels was common place in the mechanical community with the Soviet Icebreaker, the NS Lenin, being the first; however, this was certainly no icebreaker. This was considered a vessel of war, and the only ice it was breaking was the ice at the table of U.S-Soviet affairs.
