USS Roosevelt (DDG-80) History

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.

All 62 Burkes so far built are still in service as of this writing and have become the major surface ship deployed by the US Navy. The Burkes - being "multiple missions capable" - can conduct sustained combat operations at sea providing primary protection for aircraft carrier battle groups and escorting amphibious forces and their auxiliary vessels during operations. The original design was to defend against multiple Russian threats countered by the Aegis Combat System, the world's premier weapons system. The focal point is the AN/SPY-1D phased array radar being the most powerful search radar on US warships. The radar has 360-degree range and is able to detect and track hundreds of missiles and aircraft. This sea level-to-stratosphere ability to engage targets gives the crew total situational awareness. Additional radar is the SQQ-89 tactical sonar suite is composed of a hull-mounted sonar (SQS-53C) and Tactical Towed Array Sonar (TACTAS), and is fully integrated with the ship's Light Airborne Multi-Purpose Systems (LAMPS MK 111) helicopter.

The offensive and defensive capabilities of Aegis destroyers are designed with the crew in mind to provide for maximum survivability. Large areas of topside armor is placed around vital combat systems, crew areas and machinery spaces, and the large hull radically improves her sea-keeping ability. Hull plating thickness is over 75% the hull length amidships. Propellers have five blades to reduce cavitation. The stern wedge is extended out past the transom and improves fuel efficiency at cruising speeds. The Navy has factored in accommodations for the 18 member air group, and has separate female berthing for four officers, six CPOs, and 18 enlisted sailors.

Two Zodiac Marine 24-ft Rigid-Hulled Inflatable Boats (RIB) can be used for rescue or high-speed interception of other craft. Other changes include the addition of five blast-hardened bulkheads to lessen vulnerability, adding a solid waste management system, and the ability for fresh water production on board exceeding 24,000 gallons per day. The torpedo reload magazine also accommodates Penguin anti-ship and Hellfire anti-armor air-to-surface missiles, Stinger infrared surface-to-air missiles, LAU 68 2.75-in rockets, and 25-mm cannon and 40-mm grenade ammunition. She is able to carry 40 torpedoes for shipboard or helicopter use (weapons loads are mission-specific). Harpoon missiles were scratched due to the cost and this reduction does degrade the capacity for the vessel to defend itself against enemy anti-ship missiles. The ship's Recovery, Assist, Securing, and Traversing (RAST) system is utilized to move the helicopter into and out of the port and starboard hangars. This track-guided system enables the ships to move SH-60-series helicopters during rough seas.

In April 2006, the USS Roosevelt and the Dutch frigate HNLMS De Zeven Provincien closed to intercept a hijacked South Korean trawler off the coast of Somalia. Roosevelt and the De Zeven Provincien were ordered to disengage boarding the trawler when the pirates brought the crew on deck in view of the Roosevelt and pointed firearms at the crew. The hijacked trawler escaped into Somali territorial waters.

In February 2007, the Roosevelt was awarded the 2006 Battle Efficiency "E" award. Roosevelt's annual average cost of operation is $20,000,000 US.
