The hull designator denotes the hull type, it's purpose, and its propulsion mode. For example SSN stands for "Submersible Ship, Nuclear"; SSBN is Submersible Ship, Ballistic, Nuclear; and SSGN is Submersible Ship, Guided Missile, Nuclear. Any vessel that isn't a variant (rare in today's Navy) has a single designation - BB, DD, etc. Nuclear powered vessels are denoted with an "N" in the designation.
For submarine hull types, there are currently 3 in the U.S. inventory - SSN, SSGN, and SSBN. SSN's are Nuclear Fast-Attack Submarines - Sturgeon, L.A., Seawolf and Virginia Classes. SSBN's are Ballistic Missile Submarines (Ohio class, etc.) SSGN's are converted older SSBN's that have had their Ballistic Missiles removed as part of the Treaty with the former Soviet Union. They were converted to Cruise Missile launch platforms.

Some transportation methods that begin with the letter N include: Narrowboat: A long and narrow boat used for navigating canals and rivers. Nautical vessel: Any type of watercraft used for transportation on bodies of water. Nuclear-powered submarine: A submarine powered by a nuclear reactor for propulsion underwater.
You drag the word "submarine" itself onto the submarine. Then you wait for it to sink.
Narrowboats are one example.Nissan is a car maker.Nuclear submarines are military submersibles.
