Do submarines travel faster above water or below water?

The more modern teardrop shaped hull of today's submarines allows them to travel faster underwater than on the surface. This design stated with Albacore hull design.

well..submarines are designed to go faster underwater. that streamlined design actually started with the germans in WWII by the way.
in direct response to the question about the torpedo...directly stolen word for word from the haze gray site...
People frequently ask about a "200 knot torpedo" they have heard about, thinking it is a very fast torpedo of conventional type. This is not the case. Quoting from Conway's Fighting Ships of the World, 1947-1995: "Shkval is a recently-developed rocket torpedo which a submarine is expected to fire back when it detects an oncoming weapon. The cone-shaped Shkval travels within a supercavitating bubble which it produces with its own exhaust. It is fired as a conventional torpedo, and ignites its rocket after traveling 50 m from the submarine. Range is given as 6 NM at 200 knots. Running depth is 400 m. Dimensions: 53 cm x 8.2 m. The warhead is nuclear, with a preset burst range. The published designations are VA-111 and M-5."
yep, it really goes 200 knots. nope, its not a conventional propeller driven design, its a rocket torpedo. nope it don't go far. yep, it has a big bang.

definitly underwater due to the teardrop hull design.
does anyone know any reliable information about supercavitating torpedoes? I heard that they acheive supersonic speeds underwater by emmitting a gas bubble that is virtually without friction, but how are they propelled?
