"USS Nautilus SSN-571 is the world's first nuclear-powered submarine and was the first vessel to complete a submerged transit across the North Pole. Its propulsion system was a landmark in the history of naval engineering and submersible craft. During Nautilus' long career, it has established many historic firsts. On May 10, Nautilus headed for a shakedown and its longest submerged cruise was when it traveled 2,100 km from New London to San Juan, Puerto Rico. From 1955 to 1957, Nautilus continued to be used to investigate the effects of submerged speeds and endurance. On February 4, 1957, Nautilus logged its 60,000th nautical mile (111,120 km). In May, Nautilus departed for the Pacific Coast to participate in coastal exercises and the fleet exercise, operation ""Home Run,"" which acquainted units of the Pacific Fleet with the capabilities of nuclear submarines. On July 21, Nautilus returned to New London, Connecticut and departed on August 19 for its first voyage of 2,226 km (1,202 nmi) under polar pack ice. In early 1959, Nautilus completed its first overhaul on May 1959 - August 1960. On October 24, Nautilus departed New London for its first deployment with the sixth fleet in the Mediterranean Sea and returned to its home-port on December 16. On May 2, 1966, Nautilus returned to its home-port to resume operations with the Atlantic Fleet and log its 300,000th mile underway. In the next year, Nautilus conducted special operations for ComSubLant and then on August 1967, it returned to Portsmouth, and conducted exercises off the southeastern seaboard. On December 1968, Nautilus returned to New London. In 1979, Nautilus set out from Groton, Connecticut for its final voyage, reaching Mare Island Naval Shipyard of Vallejo, California on May 26, 1979. On March 3, 1980, Nautilus was decommissioned and stricken from the Naval Vessel Register."

"The Lockheed SR-71 is an advanced, long range, Mach 3 Strategic reconnaisance aircraft developed from the Lockheed YF-12A and A-12 aircraft by the Lockheed Skunk works. The SR-71 was considered the world's fastest and highest flying piloted aircraft 30 years ago up till now. The SR-71 was unofficially named as Blackbird and was called Habu (snake) by its crews. the SR-71 was the first aircraft shaped to reduce its radar cross selection, although its radar signature could be tracked by contemporary systems unlike later stealth aircraft. The defensive feature of the SR-71 aircraft is its high-speed and operating altitude. the SR-71 has a predecessor, the A-12 OXCART which was designed for the CIA bu Kelly Johnson at the Lockheed Skunk Works and he later renamed it ""Archangel"" for its design, but many documents use Johnsn's preferred name for the aircraft, the ""Article"". The USAF had planned to redesignate the A-12 aircraft as the B-71 which was the B-70 Valkyrie's successor. The public disclosure of the program and its and renaming came as a shock to everyone at the Skunk Works and to Air-Force personnel involved in the program. Although the predecessor A-12 first flew in 1962, the first flight of an SR-71 took place on december 22, 1964 at the airforce plant 42 in Palmdale, california. The first SR-71 to enter service was delivered to the 4200th Strategic Reconnaisance Wing at Beale Air Force Base, California in January 1966. A total of 32 SR-71 aircrafts were built. "

The Northrop YB-49 was a prototype jet-powered flying wing medium bomber aircraft developed by Northrop for the United States Air Force shortly after World War II. It was a development of the piston-engined YB-35, and the two YB-49s actually built were both converted YB-35 test aircraft. The aircraft was never to enter production, however, being passed over in favor of the more conventional Convair B-36 in service

"The Virginia Class Submarine is the first U.S. submarines to be designed for a broad spectrum of open-ocean and littoral missions around the world. They were designed as a cheaper alternative to the Cold War era Seawolf-class attack submarines, and are slated to replace aging Los Angeles class subs, thirteen of which have already been decommissioned. The Virginia class is tailored to excel in a wide range of war-fighting missions. These include anti-submarine and surface ship warfare; special operation forces; strike; intelligence, surveillance, and reconnaissance; carrier and expeditionary strike group support; and mine warfare. The Virginia Class Submarine has a weapons launch of four 21-inch torpedo tubes & 12 vertical launch system tubes. Its weapon comprises of tomahawk land-attack missiles, Unmanned Undersea Vehicles (UUV), Mark 48 advanced capability torpedoes, and advanced mobile mines. The New Attack Submarine also features an integral Lock-Out/Lock-In chamber for special operations and can host Special Operations Forces' underwater delivery vehicles. "

"Virginia Class Submarine was intended to be comparable in most respects to its immediate predecessor - the Seawolf - but in a more affordable configuration. The missions of Virginia include Covert Strike Warfare, Anti-Submarine Warfare, Covert Intelligence Collection/Surveillance, Covert Indication and Warning and Electronic Warfare, Anti-Surface Ship Warfare, Special Warfare, Covert Mine Warfare, and Battle Group Support. The Virginia class submarines are the first class of submarine to be designed and influenced by post-Cold War needs. With the emphasis no longer on open ocean SLOC (Sea Lanes of Communication) warfare against the Warsaw Pact, the Virginia, though still capable of traditional ""blue water"" deep ocean missions, focuses on ""littoral"" missions, specifically special operations support, intelligence gathering, and counter mine operations. While it carries the same weapons as its Cold War predecessors (the Seawolf class and Los Angeles class attack submarines) its weapon load out is significantly smaller (roughly half that of the Sea Wolf.) In addition, where the Seawolf featured eight 660mm ""swim out"" low transient signature torpedo tubes, the Virginia is armed with only four conventional 533mm tubes. The Virginias however, are the first class of submarine specifically built to incorporate the regular use of ROV sensors. The SSN 774 was christened on August 16, 2003, and is undergoing dockside outfitting and testing. Virginia started builder’s trials in 2004. "

"USS Nautilus SSN-571 was the world's first operational nuclear-powered submarine and the first vessel to complete a submerged transit across the North Pole. The USS Nautilus was initially put to initial sea trials in January 20, 1955. From 1955 to 1957, Nautilus continued to be used to investigate the effects of increased submerged speeds and endurance. On February 4, 1957, Nautilus logged its 60,000th nautical mile (111,120 km), matching the endurance of the fictional Nautilus described in Jules Verne's novel Twenty Thousand Leagues Under the Sea. In May, Nautilus departed for the Pacific Coast to participate in coastal exercises and the fleet exercise, operation ""Home Run,"" which acquainted units of the Pacific Fleet with the capabilities of nuclear submarines. Nautilus returned to New London, Connecticut, on July 21 and departed again on August 19 for her first voyage of 2,226 km under polar pack ice. On October April 25, 1958, Nautilus was underway again for the West Coast at San Diego, California, San Francisco, California and seattle, Washington. On June 28, Nautilus arrived at Pearl Harbor to await better ice conditions. Nautilus became the first ship to reach the geographic North Pole. Nautilus was designated a National Historic Landmark by the United State Secretary of the Interior on May 1982. Nautilus was named as official state of ship of Connecticut in 1983. 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. "

"USS Dallas (SSN-770), a Los Angeles-class submarine, is one of two ships of the United States Navy to be named for Dallas, Texas, although another two ships were scheduled but never completed. The LA class serves as the backbone of the United States submarine force. The LA class is an attack submarine, whose mission is to engage enemy surface ships and submarines perform covert operations, and to protect carrier battle groups (CVBGs), which are the primary unit of US naval/military power. The USS Los Angeles (SSN-688) was ordered on January 8, 1971, and was commissioned on November 13, 1976. USS Dallas (SSN-700) was launched on April 28 1979 and was commissioned on July 18 1981. Dallas is assigned to the US Atlantic Fleet and is home ported at Groton, CT. Since then, eighty-five Los Angeles Class ships have been delivered to the US Navy, with most of them still operating in 2002. USS Dallas was featured prominently in the novel and film adaptation of Tom Clancy's The Hunt for Red October. The USS Dallas was also featured as the submarine commanded by Tessa's late father in Full Metal Panic!, it was the Dallas that was in peril and ended up being saved by Richard Merdukas. USS Dallas was mentioned in the BBC drama Threads as being sunk (presumably by Soviet forces) in the waters off Iran in the lead up to war. "

"U-boat is the anglicized version of the German word U-Boot (help•info), itself an abbreviation of Unterseeboot (undersea boat), and refers to military submarines operated by Germany, particularly in World War I and World War II. Although in theory, U-boats could have been useful fleet weapons against enemy naval warships, in practice they were most effectively used in an economic-warfare role, enforcing a naval blockade against enemy shipping. The primary targets of the U-boat campaigns in both wars were the merchant convoys bringing supplies from the British Empire and the United States to the island of Great Britain. Austrian submarines of World War I were also known as ""U-Boats"". The distinction between U-boat and submarine is common in English-language usage (where U-boat refers exclusively to the German vessels of the World Wars) but is unknown in German, in which the term U-Boat refers to any submarine.

"The PT-109 boat was commanded by 35th United States President John F. Kennedy, an Elco PT-103 class torpedo boat. During World War II, The Elco boats were the largest PT boats operated by the United States Navy. At 80 feet (24 m) and 40 tons, they had strong wooden hulls of 2-inch (5 cm) mahogany planking. Powered by three 12-cylinder 1,500hp (1100 kW) Packard gasoline engines (one per propeller shaft), their designed top speed was 41 knots (76 km/h). For space and weight-distribution reasons, the center engine was mounted with the output end facing forward, with power transmitted to the propeller shaft through a V-drive gearbox. Because the center propeller was deeper, it left less of a wake, and was preferred by skippers for low-wake loitering. The engines were fitted with mufflers in the stern to direct the exhaust under water, which had to be bypassed for high speed. These were used not only to mask their own noise from the enemy but to be able to hear enemy aircraft, which were rarely detected overhead before dropping their bombs. The only completely restored 80' Elco PT-boat in existence, PT 617, is on display at the Battleship Cove Museum in Fall River, Massachusetts. Decorated as the PT-109, PT 796 was used as a float in John F. Kennedy's inaugural parade."

"PBR (Patrol Boat, River), also called “Riverine” and “Pibber”, is the US Navy designation for a type of rigid-hulled patrol boat used in the Vietnam War from March 1966 until the end of 1970. They were deployed in a force that grew to 250, the most common craft in the River Patrol Force, Task Force 116, and were used to stop and search traffic in areas such as the Mekong Delta, the Rung Sat Special Zone, the Saigon River and in I Corps, in the area assigned to Task Force Clearwater, in an attempt to disrupt weapons shipments. In this role they frequently became involved in firefights with enemy soldiers on boats and on the shore. PBR's were also used to infiltrate Navy SEAL teams. The Mark II version, 32 feet long and one foot wider beam, had improved drives to reduce fouling, and aluminum gunwales to resist wear. It usually operated with four enlisted men, of which the most senior crewman was designated the boat commander. They were powered by dual 220 hp (164 kW) Detroit Diesel engines with Jacuzzi Brothers water jet drives. The boats reached top speeds of 28.5 knots (53 km/h). The boat was typically armed with twin .50 caliber (12.7 mm) machine guns (the forward '50s), an M60 7.62 mm machine gun, a Mark 18 grenade launcher, and sometimes a 20 mm cannon. The machine gunners and conning tower were protected with ceramic armor. The Patrol Boat Riverine is currently displayed at the New Jersey Naval Museum in Hackensack, NJ. The PBR was featured in the movie Apocalypse Now (1979). This is the very same type of fiberglass craft used in the film. The units using the PBRs were often called “The Brown Water Navy” (and those rivers were pretty brown) and also “Swift Boats” (and at 30 Knots fully loaded they PBRs were swift). "

"The first USS Gato submarine was first launched in 21 August 1941, commissioned in 31 December 1941 and decommissioned in 16 March 1946. It was the first submarine that was produced massively between 1941 and 1945. In New York and Baltimore, the submarine was placed in service as a Naval Reserve Training vessel. And in March 1 1960, it was placed out of service from the Navy. From its service in the Second World War, it received battle stars and a Presidential Unit Citation. It has the finest American design and has the standard type of US submarine from the Second World War. It was based on the Tambor submarine. Modifications and improvements were done on the Gato to increase its combat abilities. Batteries and its engines were improved to increase the period of its patrol."

"The Hindenburg (LZ-129) was a German zeppelin. Along with its sister ship the Graf Zeppelin II, it was the largest aircraft ever built. It was named after Paul von Hindenburg, the president of Germany from 1925 to 1934. During its second year of service, it was destroyed by a fire while landing at Lakehurst Naval Air Station in Manchester Township, New Jersey, on May 6, 1937. The Hindenburg was built by Luftschiffbau Zeppelin in 1931 to a new, all-duralumin design. It was a visually striking “ship of the air”, at 804 feet long and 135 feet in diameter. It was longer than three Boeing 747s placed end to end, longer than four Goodyear Blimps end to end, and only 79 feet shorter than the Titanic. It was originally equipped with cabins for 50 passengers and a crew complement of 40, though on the last flight there were an additional 21 crew members in training. To reduce drag, the passenger rooms were contained entirely within the hull, rather than in the gondola as on the Graf Zeppelin. During its first year of commercial operation in 1936, the Hindenburg flew 308,323 km carrying 2,798 passengers and 160 tons of freight and mail. It made 17 round trips across the Atlantic Ocean, with ten trips to the US and seven to Brazil. In July of that year it also completed a record Atlantic double-crossing in 5 days, 19 hours and 51 minutes. The German boxer Max Schmeling returned home on the Hindenburg to a hero's welcome in Frankfurt, after defeating Joe Louis. On August 1 the Hindenburg was present at the opening ceremonies of the 1936 Summer Olympics in Berlin. Moments before the arrival of Adolf Hitler, the airship crossed over the Olympic stadium, trailing the Olympic flag from its gondola."
