Known as the Cold War, this conflict began as a struggle for control over the conquered areas of Eastern Europe in the late 1940s and continued into the early 1990s. Initially, only the United States possessed atomic weapons, but in 1949 the Soviet Union exploded an atomic bomb and the arms race began.
From 1897 to 1914, a naval arms race between the United Kingdom and Germany took place. British concern about rapid increase in German naval power resulted in a costly building competition of Dreadnought-class ships. This tense arms race lasted until 1914, when the war broke out.
The British government accepted that Naval superiority was essential to national security. It had a big and well funded Navy, and a relatively small Army. Whereas the continental powers had to have large armies, because of their land borders. Once England and Scotland united, there were no land borders to defend.
The British Navy scored its greatest victories largely because it was better organized, better financed and better equipped than its enemies. For this, Pepys gets much of the credit. In the Elizabethan era, ships were thought of as little more than transport vehicles for troops.
A Britain ruled the waves, in part, because no one else attempted to. The other candidates, France, America and Russia, all underwent internal upheaval or had other priorities for much of the 19th century that prevented them from making a serious challenge to British control of the world's oceans.
Britannia no longer rules the waves. For all that, though, its navy remains a world-class force despite its shriveled inventory of ships and aircraft.
Since its completion in 1986, submarines at Barrow are constructed inside the Devonshire Dock Hall (DDH). In addition to the main shipyard in Barrow-in-Furness, BAE Systems Submarines also operates from sites at Farnborough, Ash Vale, Frimley and Weymouth.

Seawolf class submarines
The Seawolf class submarines are arguably the quietest submarines in the world ever constructed. It is exceptionally quiet even at high speeds.
A nuclear submarine can dive to a depth of about 300m. This one is larger than the research vessel Atlantis and has a crew of 134. The research vessel Atlantis, shown at the surface, is 274 feet long. At this scale the divers and their small boat are almost invisible.

The futuristic undersea warship will ensure that Tokyo retains its reputation for the quietest, most modern non-nuclear submarines in the world. A Sōryū class submarine anchored at the naval base at Kure, Japan. Note x-shaped stern planes emerging from the water at a 45 degree angle.

The longest submerged and unsupported patrol made public is 111 days (57,085 km 30,804 nautical miles) by HM Submarine Warspite (Cdr J. G. F. Cooke RN) in the South Atlantic from 25 November 1982 to 15 March 1983.
So, what we do is all the poop and all the excrement and all that stuff goes into the sanitary tanks. There's three sanitary tanks onboard a submarine. So what you have to do to discharge it is you have to pressurize a sanitary pump that blows the sanitary waste outside of the boat.
about twenty years
Nuclear power allowed submarines to run for about twenty years without needing to refuel. Food supplies became the only limit on a nuclear submarine's time at sea. Since then, similar technologies have been developed to power aircraft carriers.
The Navy announced today a ban on smoking aboard submarines while they are deployed below the surface after medical testing showed non-smokers suffered effects of second-hand smoke. It will take effect by Dec. 31, 2010.
Britain, Canada and the U.S. Navy do not put women on submarines primarily because of these irresolvable health risks and operational complications. In addition, habitability standards on subs are well below minimum standards on surface ships.
In the mid-1970s, smoking was allowed virtually everywhere aboard submarines, the study says. By the year 2000, smokers were contained to two six-by-six foot areas on subs. Williams counted his victories one at a time with each patient he helped kick the habit.
three to four months
Nuclear submarines can operate underwater for three to four months at a time and easily span seas. While few conventional submarines can travel the distance, none have the same depth of endurance below.
