The fastest known nuclear submarine to date was the Russian ALFA class (NATO reporting name) submarine. Its design featured a lead-bismuth cooled reactor, enabling the reactor to be much smaller and powerful, making the boat design more streamlined and capable of reaching higher speeds. Its top sustained submerged speed was 41-42 knots, with speed burst capabilities of between 43 and 45 knots. I could reach top speed within a minute.
Most boats can only maintain between 12-15 knots on the surface - this is because modern submarine designs are to allow them to travel much faster underwater than on the surface. The average for most boats is between 25 - 35 knots submerged, depending on class and screw configuration.
Modern submarines are designed to go much faster underwater than on the surface - typically, top speed on the surface is around 17 knots for most boats.

Were most of the submarines in the Falklands War nuclear powered?
Argentina had diesel-electric submarines while the British had nuclear-powered submarines.
Did any nuclear submarines sink?
A number of nuclear submarines sank, and the circumstances vary from accident to accident. Wikipedia has a list, and by going there and entering "List of sunken nuclear submarines" you can review that list.
What are the basic idea of nuclear submarines?
Nuclear submarines are powered by a nuclear reactor and they are completely independent of air, so there is no need to surface frequently.
Which countries have nuclear submarines?
The US, Russia, Great Britain, France, China and (recently) India have nuclear submarines.
Do nuclear submarines generate nuclear power on the submarine?
Yes, nuclear submarines generate nuclear power. There is a nuclear reactor on board (hence the tern nuclear submarine) which creates steam to drive the main engines to turn the screw(s).

Is plutonium in navy nuclear applications?
Plutonium can be used in nuclear reactors for nuclear propulsion of ships and submarines.
Do submarines need gas?
No - all submarines, be it nuclear or diesel-electric, use diesel fuel, either for primary engines (DE) or backup generator (nuclear).
Are the UK's nuclear missiles based in submarines?
Since its free-fall nuclear weapons arsenal was decomissioned in 1998, the United Kingdom's only means of nuclear weapons delivery is via submarines and SLBMs.
