USS Albacore was a unique research submarine that pioneered the American version of the teardrop hull form (sometimes referred to as an "Albacore hull") of modern submarines. On modern military submarines the outer hull (and sometimes also the propeller) is covered with a thick layer of special sound-absorbing rubber, or anechoic plating, to ...
A submarine (or sub) is a watercraft capable of independent operation underwater. (It differs from a submersible, which has more limited underwater capability.) [2] The term “submarine” is also sometimes used historically or informally to refer to remotely operated vehicles and robots, or to medium-sized or smaller vessels (such as the midget submarine and the wet sub).
There are three major types of submarines in the United States Navy: ballistic missile submarines, attack submarines, and cruise missile submarines. All submarines currently in the U.S. Navy are nuclear-powered. Ballistic missile submarines have a single strategic mission of carrying nuclear submarine-launched ballistic missiles.
A 16th-century Islamic painting depicting Alexander the Great being lowered in a glass submersible. The concept of underwater transport has roots deep in antiquity. There are images of men using hollow sticks to breathe underwater for hunting at the temples at Thebes, and the first known military use occurred during the siege of Syracuse (415–413 BC), where divers cleared obstructions ...
There was a risk that the submarine would become disoriented beneath the ice and that the crew would have to play "longitude roulette". Commander Anderson had considered using torpedoes to blow a hole in the ice if the submarine needed to surface. [25] The most difficult part of the journey was in the Bering Strait. The ice extended as much as ...
Commissioned in 1958, the USS Growler patrolled seas off the coast of Russia during the Cold War.
A submarine arms race is intensifying as China embarks on production of a new generation of nuclear-armed submarines that for the first time are expected to pose a challenge to growing U.S. and ...
The Soviet large nuclear ballistic missile submarine was the Project 941 Akula, more famously known as the Typhoon class (and not to be confused with the Project 971 Shchuka attack submarine, called "Akula" by NATO). The Typhoons were the largest submarines ever built, at 48,000 tons submerged (more than 2½ times the displacement of the Ohio ...
