"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 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."

"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. "
