The largest subs in WWII were the Japanese I-400 Class subs; they could launch 3 airplanes.
10 mph underwater 20 mph surface
Average: 20 knots surfaced 09 knots submerged
The 2 most advanced submarines currently in service are the U.S. Virginia-class and the British Astute-class fast-attack submarines. Both are technologically comparable in capability.
U.S. Virginia and British Astute class Fast-Attack submarines are considered the 2 top state of the art submarines in the world today. The U.S. and Britain often share technology, and as such the capabilities of each are similar.
There are no known submarines named Juliet. However, the name Juliet is used by NATO to identify a class of Soviet submarines that are no longer in operation. It was a diesel-electric submarine capable of launching cruise missiles. Most American World War II submarines were named after species of fish. Most early nuclear-powered submarines were named after World War II submarines. The first generation of nuclear-powered ballistic submarines were named after famous Americans. Most Los Ageles-class fast attack submarines are named after U.S. cities, with the exception of the USS Hyman G. Rickover. Most Ohio-class guided missle and ballistic missile submarines are named after U.S. states, with the USS Henry M. Jackson being the exception. The Virginia-class fast attack submarines are mostly named after U.S. states. The lone exception as of January 2011 is the John Warner, which is expected to be delivered in 2015.
USN Gato class subs in WWII could about 20 knots surface, and about 9 knots underwater.
USA. nuclear powered submarines can go faster than 25 knots (nautical miles per hour) underwater.
That is the most efficient shape for fast, silent, speed underwater.
According to Wikipedia the US Navy has: Los Angeles class (29 in commission, 2 in reserve) – fast attack submarines Ohio class (18 in commission) – 14 ballistic missile submarines (SSBNs), 4 guided missile submarines (SSGNs) Seawolf class (3 in commission) – fast attack submarines Virginia class (19 in commission, 1 delivered, 1 fitting out, 7 under construction, 2 on order) – fast attack submarines The existing fleet of ballistic submarines currently carries 54 percent of the United States' nuclear deterrent arsenal.
