USS Roosevelt (DDG-80) Guided-Missile Destroyer (2000)
The Arleigh Burke-class of fighting surface ships is the only active destroyer class currently in service with the United States Navy.
The USS Roosevelt (DDG-80) is an Arleigh Burke-class of guided-missile destroyers in service with the United States Navy and has become the U.S. Navy's only active destroyer class. The class is named after Admiral Arleigh "31-Knot" Burke, the most famous American destroyer officer of World War 2. The Roosevelt is the second Flight IIA ship commissioned and is the 30th ship of the Arleigh Burke-class. In 1996, the Secretary of the Navy John H. Dalton, named the Roosevelt for the nation's former First Couple - Franklin D. Roosevelt, the 32nd President of the United States and former First Lady, Eleanor Roosevelt. The Arleigh Burke ships are the largest and most powerful destroyer class built by the United States.
The total cost in US funds of the first ship was put at $1.1 billion, plus an additional $778 million needed for the ship's weapons systems. She was built at the Bath Iron Works company at Bath, Maine and launched on September 16, 1989 by Mrs. Arleigh Burke. The third major upgrade to the class is the Flight IIA Arleigh Burke ships. Improvements to Roosevelt over the Flight I ships included the addition of two hangars for ASW (Anti-Submarine Warfare) helicopters. These vessels are 4 feet, 5 inches longer and have an additional 1,300 tons displaced. The crew was increased by 57 sailors including the helicopter crew of 4 officers and 14 aircrew. As new ships are brought online they also include upgrades based on new technology and experience of the sister ships. Learning lessons from the Ticonderoga-class guided-missile cruisers - themselves experiencing cost and upgrade difficulties - the "Burks" design used stealth-angled surfaces to help counter anti-ship missiles and were new ships in the class were modified while still under construction, not after launching, to reduce cost.
Initially, Burkes were built with aluminum superstructures on a steel hull to conserve weight. Due to the battle damage incurred from an Exocet anti-ship missile against the aluminum superstructure on the destroyer HMS Sheffield in the Falklands War and other new emerging technologies, Burks have gone back to an all-steel construction. Her CPS system makes the Arleigh Burke-class the first U.S. warships designed with an air-filtration system against "weapons of mass destruction" warfare. This positive pressure protection system removes airborne chemical, biological, radiological and nuclear (CBRN)contaminants from the air, allowing for operations on board the ship to proceed as normal without the need for the crew to use individual protection equipment (IPE).
Later Flight IIA ships, starting with USS Mustin, have a modified funnel design that hides the funnels within the superstructure to reduce radar signature. TACTAS Towed array sonar was removed from flight IIA ships onwards along with the Harpoon anti-ship missile launchers. Ships DDG-68 to DDG-84 have AN/SLQ-32 antennas that resemble the V3 deployed on Aegis-class cruisers, and V2 variants externally resemble those as found on Perry-class frigates. A number of Flight IIA ships were constructed without a Phalanx CIWS because Evolved Sea Sparrow Missiles were planned to be installed - the final decision by the Navy was to retrofit all IIA ships to carry at least one Phalanx CIWS as on Roosevelt.
