it was named Nautilus
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).
Either a nuclear reactor or batteries.
This depends on both the role (e.g. missile, attack, research) and class of the submarine. The only thing that defines a submarine as nuclear is that it derives its power from nuclear reactors, it does not need to carry nuclear weapons (although almost all do).Role defines the purpose the submarine was designed to fulfillClass is the specific "model" of the submarine
Nothing but the terminology. "Atomic" was the term used in the early days of nuclear weapons and nuclear power. "Nuclear" (describing the fission process of nuclear power and nuclear weapons) became the term when fusion bombs became reality, as Atomic can refer to both fission and fusion processes.
Sorry, but that information is classified.
A nuclear powered submarine uses nuclear power for propulsion and all other on-board activities that need power, like lighting, cooking and computers. This applies on all voyages not just in the Gulf of Mexico.
They typically run on steam power, using nuclear reactors to create the steam. Prior to the development of the nuclear power systems, they used electric motors through batteries, that were charged using diesel engines. On the surface the diesel also propelled the shafts.
The first operational nuclear submarine, the USS Nautilus(SSN-571), was developed by the United States. The idea of a submarine dates far back in history, but the technology required to actually build an operational undersea boat is relatively new. Applying nuclear power to this concept is newer still, and it had to wait until nuclear power could be harnessed in the form of a safe and reliable nuclear reactor. A link can be found below for more information.
Yes. The idea of the submarine is the element of surprise. Before nuclear power submarines ran on either battery power or diesel power. Every so often it needed to surface (or use a snorkle - no kidding, it's called a snorkle) to run the diesel (which would both propel the sub and charge the battery) Now, with nuclear power, the submarine can stay underwater as long as there is food for the crew. A submarine nuclear reactor can last for years.
In terms of fire power that would be the Trident submarine. In terms of propulsion power that would be the Enterlprise, with 8 nuclear reactors.
India has been struggling to get a nuclear submarine in the water for some time. The technical challenges of "shrinking" a nuclear power plant to get one to fit on something the size of the submarine were daunting. On 26 July, 2009, India launched INS Arihant to gain them entry into the nuclear submarine club. That date might be the one asked about here, if something "exact" is being sought.
Submarines are powered by diesel fuel (in the past) or more recently by nuclear reactors. Nuclear reactors provide advantages in range and in noise produced.
