Submarine ship. Nautilus was designated a National Historic Landmark by the United States Secretary of the Interior on 20 May 1982. She was named as the official state ship of Connecticut in 1983. Following an extensive conversion at Mare Island Naval Shipyard, Nautilus was towed back to Groton, Connecticut arriving on 6 July 1985. On April 11, 1986, Nautilus opened to the public as part of the U.S. Navy Submarine Force Library and Museum. Nautilus now serves as a museum of submarine history, after undergoing a five-month preservation in 2002, at the Electric Boat division of General Dynamics, at a cost of approximately $4.7 million. The historic ship Nautilus attracts some 250,000 visitors annually to her present berth near the Naval Submarine Base New London. Meanwhile, in August 1951, the Bureau of Ships (now the Naval Ship Systems Command) awarded contract for the construction of the first nuclear powered submarine. From this point onward, events moved rapidly. Nautilus’ keel was laid 14 June 1952 at Groton. President Harry Truman presided at the keel-laying ceremonies for the Nautilus. By 1952, the Electric Boat Company, builder of USS Nautilus in Groton, Connecticut, had installed the main turbine, condenser, reduction gear, and other parts in the submarine's engine room. The pressure vessel was installed in the reactor compartment. She was christened on 21 Jan 1954 and was commissioned 30 Sept 1954. USS Nautilus (SSN-571) (wallpaper 4).

Her nuclear power propulsion plant was first operated at power on 20 December 1954 and first developed full power alongside the dock on 3 January 1955. USS Nautilus went to sea propelled by a pressurized-water nuclear reactor plant a few days later. On 17 January 1955 Nautilus, putting to sea for the first time, signaled her message: “Underway on nuclear power.” Her Mark II reactor, a refined version of the prototype Mark I reactor, behaved beautifully. During her first sea trials, she completed high speed test runs, both surfaced and submerged, and dived more than 50 times. After further testing, she was accepted by the Navy on 22 April 1955. She then proceeded to smash just about every existing record that pertained to subs. On her shakedown cruise in May, Nautilus steamed submerged from New London, Conn., to San Juan, Puerto Rico, traveling over 1300 miles in 84 hours – more than 10 times further than any submarine had ever traveled while submerged. It was the first time that a combatant submarine had maintained such a high submerged speed (about 16 knots) for longer than an hour, the longest period spent submerged by a U. S. submarine, and the fastest passage between New London and San Juan by any submarine, surfaced or submerged, She later made an even faster submerged passage from Key West to New London, a distance of 1397 miles, at an average speed of more than 20 knots.

Submarine ship. Following fleet exercises in early 1959, Nautilus entered the Portsmouth Naval Shipyard in Kittery, Maine, for her first complete overhaul (28 May 1959 – 15 August 1960). Overhaul was followed by refresher training and on 24 October she departed New London for her first deployment with the Sixth Fleet in the Mediterranean Sea, returning to her home-port 16 December. Nautilus operated in the Atlantic, conducting evaluation tests for ASW improvements, participating in NATO exercises and, during October 1962, in the naval quarantine of Cuba, until she headed east again for a two month Mediterranean tour in August 1963. On her return she joined in fleet exercises until entering the Portsmouth Naval Shipyard for her second overhaul 17 January 1964. On 2 May 1966, Nautilus returned to her home-port to resume operations with the Atlantic Fleet, and at some point around that month, logged her 300,000th mile (560,000 km) underway. For the next year and a quarter she conducted special operations for ComSubLant and then in August 1967, returned to Portsmouth, for another year's stay, following which she conducted exercises off the southeastern seaboard.

She returned to New London in December 1968. At the request of then-Captain H. G. Rickover, USN, the first study of the application of a high-pressure, water-cooled reactor for a submarine was undertaken at Oak Ridge, Tenn., in September 1947. In January 1948 the Department of Defense requested the Atomic Energy Commission to design, develop and build a nuclear reactor which would propel a submarine. In August 1949 the Chief of Naval Operations established an operational requirement to develop a submarine nuclear propulsion plant with a ready-for-sea date of January 1955. The late Admiral Forrest P. Sherman, then CNO, recommended the construction of a nuclear submarine to Congress on 25 Apr. 1950, and the following August, the President signed Public Law 674 which authorized construction of Nautilus. That same month saw the start of construction of the Nautilus land-based prototype (submarine thermal reactor, Mark I) at the AEC’s National Reactor Testing Station in Idaho. Mark I (Nautilus was known as STR Mark II) was built from the start inside a submarine hull, complete with a surrounding tank of water, on the assumption that it was a true seagoing power plant. Breadboard techniques and engineering shortcuts were riot allowed. The model went critical at 11:17 PM, MST on 30 Mar 1953 – an occasion which marked the first production of significant quantities of useful nuclear power in the world. About three months later, on 25 June, Mark I commenced a 96-hour sustained full-power run, simulating a submerged crossing of the Atlantic. USS Nautilus (SSN-571) (wallpaper 3).

Submarine ship. In July 1951 the US Congress authorized the construction of a nuclear-powered submarine for the U.S. Navy, which was planned and personally supervised by Admiral Hyman G. Rickover, known as the "Father of the Nuclear Navy." On 12 December 1951 the U.S. Department of the Navy announced that the submarine would be called Nautilus—the fourth U.S. Navy vessel officially so named and would carry the hull number SSN-571. Nautilus's keel was laid at General Dynamics' Electric Boat Division in Groton, Connecticut by Harry S. Truman, President of the United States, on 14 June 1952, and the ship was designed by John Burnham. She was christened on 21 January 1954 and launched into the Thames River, sponsored by Mamie Eisenhower, the wife of Truman's successor Dwight D. Eisenhower. Nautilus was commissioned on 30 September 1954, under the command of Commander Eugene P. Wilkinson, USN. USS Nautilus set a new standard for submarines. Rather than a surface ship capable of submerging when the need arose, this submarine’s natural environment lay below the surface. USS Nautilus (SSN-571) (wallpaper 2).

After USS Nautilus (SSN-571) American submarines had virtually unlimited submerged endurance and the ability to conduct extended patrols in a hostile environment – a practice that became highly secret and routine over nearly fifty years of Cold War. Nautilus was the world's first nuclear powered warship, and the first submarine to be equipped with a nuclear reactor. Authorized in August 1951, she joined the fleet on 30 September 1954, though remained dockside for several months while fitting out. On 17 January 1955 she pulled away from the dock at Groton CT and signalled at 1100, "underway on nuclear power", then proceeded to make the longest submerged passage in history, to Puerto Rico breaking the highest sustained submerge record en route. She remained an experimental testbed for her entire career and was deactivated in March 1980, designated a national landmark 20 May 1982 and towed to Groton in July 1985 to begin her new career as a museum. The advent of nuclear power for ship propulsion had a profound effect on everyone involved in undersea warfare. Since the technology was completely new, Rickover had to provide the staff at Electric Boat Division (EB) with a broad education in physics, nuclear engineering, and steam systems suited for submarine propulsion. The admiral also knew that the technology would, in its turn, instruct both the Navy and civilian shipbuilders. Nautilus forced the Navy, industry, and science to learn more about quieting, highly toxic liquid metals, vibration at sustained high speed, and the necessity of carefully managing construction materials. When a pipe that did not meet the proper specifications failed during the final dockside trials of the Nautilus cooling system before the reactor went critical, EB learned the most fundamental lesson of all: Failure to measure up to the demands of the technology could have devastating results.

Submarine ship. USS Nautilus (SSN-571) is the world's first operational nuclear-powered submarine. She was also the first vessel to complete a submerged transit across the North Pole. Namesake of the submarine in Jules Verne's Twenty Thousand Leagues Under the Sea, and named after another USS Nautilus (SS-168) that served with distinction in World War II, Nautilus was authorized in 1951 and launched in 1954. Because her nuclear propulsion allowed her to remain submerged for far longer than diesel-electric submarines, she broke many records in her first years of operation and was able to travel to locations previously beyond the limits of submarines. In operation, she revealed a number of limitations in her design and construction; this information was used to improve subsequent submarines. The Nautilus was decommissioned in 1980 and designated a National Historic Landmark in 1982. She has been preserved as a museum of submarine history in Groton, Connecticut, where she receives some 250,000 visitors a year. USS Nautilus was the first nuclear-powered submarine.

Electric Boat Company in Groton, Connecticut—the same company that had sold the U.S. Navy its first submarine in 1900—laid her keel 14 June 1952. She was launched 18 months later and commissioned in September 1954. Although Nautilus was a large boat for her time—323 feet (98 m) long and displacing 4,092 tons submerged, with a crew of 104—she was also fast. The newly developed S2W (Submarine, Model 2, Westinghouse) pressurized-water nuclear reactor provided her power both on the surface, where her top speed was 22 knots (41 km/hr), and underwater, where she could do 23 knots (42 km/hr). Admiral Hyman G. Rickover is seated behind Senator Clinton P. Anderson, chairman of the Joint Committee on Atomic Energy, at the controls of USS Skipjack (SSN-585) shortly before her 1959 commissioning. Rickover made a practice of personally riding each nuclear-powered submarine during her trials, to underline publicly his confidence in the nuclear-powered submarine design principles he espoused: simplicity, reliability, and, above all, safety. After graduating from the U.S. Naval Academy in 1922, Rickover went to sea for several years before earning a 1929 master's degree in electrical engineering from Columbia University. During World War II, he served effectively as head of the Bureau of Ships electrical section. Rickover became the driving force in the U.S. Navy's nuclear propulsion program, against sometimes strenuous opposition. He retired after 63 years of active duty in 1981 and died in 1986.
