Six Typhoon-class submarines were built between 1976 and 1985. Originally, the submarines were designated by hull numbers only. Names were later assigned to the four vessels retained by the Russian Navy after the dissolution of the Soviet Union. During the time of the Russian Federation, these boats were to be sponsored by either a city or company.
The Ohio class of nuclear-powered submarines includes the United States Navy's 14 ballistic missile submarines (SSBNs) and its four cruise missile submarines (SSGNs). Each displacing 18,750 tons submerged, the Ohio-class boats are the largest submarines ever built for the U.S. Navy, and are capable of carrying 24 Trident II missiles apiece.
Her surface sea-keeping was further enhanced by high reserve buoyancy (30%), provided by 22 ballast tanks, the most ever in an American submarine. [13] She was the last submarine to have a conning tower, as well as the last American submarine to have twin screws or a stern torpedo room. Her sail was the largest ever aboard an American submarine ...
The U.S. Navy nuclear-powered radar picket submarine Triton (pictured) was the largest, most powerful, and most expensive submarine ever built at the time of her commissioning, costing $109,000,000 excluding the cost of her nuclear fuel and reactors. [10]
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 ...
The I-400s remained the largest submarines ever built until the construction of nuclear ballistic missile submarines in the 1960s. The IJN called this type of submarine Sentoku type submarine ( 潜特 型潜水艦 , Sen-Toku-gata sensuikan, Submarine Special ) , shortened from Toku -gata Sen suikan ( 特 型 潜 水艦 , Special Type Submarine ) .
Originally smaller, jumboisation made Seawise Giant the largest ship ever by length, displacement (657,019 tonnes), and deadweight tonnage.

Overall, she is generally considered the largest self-propelled ship ever built. [6] [7] In 2013 her overall length was surpassed by 30 m by the floating liquefied natural gas installation Shell Prelude , a monohull barge design 488 m (1,601 ft) long and 600,000 tonnes displacement. Seawise Giant's engines were powered by Ljungström turbines.
