It has a length of 170m, A width of 23m and a draught of 12m. It is capable of 22.22 knots and had a combined power of 608800HP. It is also armed with 9K38 Igla SAM, 2x650mm torpedo tubes, RPK-7 anti-ship missiles, Type 65K torpedos, 4x533mm torpedo tubes, RPK-2 Viyuga cruise missiles, and Type-53 Torpedos It could dive up to 500m

Answer 4

The smallest submarine is the U.S. Navy's NR-1, a specially designed nuclear submarine with a crew of about a 13 officers and enlisted. Even today its operations are still highly classified, but more is known about her capabilities. For example, she's fitted with underwater lights, cameras, and can literally travel on the bottom of the ocean courtesy of Good Year truck tires.

The NR-1 was never commissioned as a warship - by designating it a research and deep submergence vessel, then Admiral Hyman Rickover kept an allocation for a warship in the budget as well as excluded the NR-1 from bureaucratic oversight normally associated with military units. This freed the NR-1 to do missions that most other boats could not.

Though it's called a deep submergence craft, it's a submarine in every sense of the word. Even with the need for a support vessel, she can still maintain submerged operations longer than any other DSRV, which aren't nuclear powered like the NR-1. It's small size hides it capability - I remember seeing it in Groton when we used to go for pre-deployment training. Looks like a toy boat next to a Fast-Attack, but duty on it is highly selective.
