DDG-51 ARLEIGH BURKE-class
DDG-51 柏克級飛彈驅逐艦
原文:
The composition of the fleet is changing rapidly as modern ARLEIGH BURKE guided missile AEGIS destroyers enter active commissioned service. The Navy considers the newest Arleigh Burke-class destroyer to be its most capable and survivable surface combatant. The DDG 51 was the first U.S. Navy ship designed to incorporate shaping techniques to reduce radar cross-section to reduce their detectability and likelihood of being targeted by enemy weapons and sensors. Originally designed to defend against Soviet aircraft, cruise missiles, and nuclear attack submarines, this higher capability ship is to be used in high-threat areas to conduct antiair, antisubmarine, antisurface, and strike operations.
DDG 51s were constructed in flights, allowing technological advances during construction. Flight II, introduced in FY 1992, incorporates improvements to the SPY radar and the Standard missile, active electronic countermeasures and communications. Flight IIA, introduced in fiscal year 1994, added a helicopter hangar with one anti-submarine helicopter and one armed attack helicopter.
The initial ARLEIGH BURKE-class guided missile destroyers have a full load displacement of 8,300 tons, are 506 feet in overall length and have a 62 foot beam. They are driven by two shafts powered by four LM2500 engines. Their maximum speed is in excess of 30 knots and they have a cruising range of 4,400 n. miles at 20 knots. The ships complement is about 30 officers and 302 enlisted personnel.
All ships of this class have the AEGIS air defense system with the SPY-1D phased array radar. They are armed with a 90-cell Vertical Launching System capable of storing and rapidly firing a mix of Standard, Tomahawk, and Vertically Launched ASROC (VLA) missiles for either Air Defense, Strike Warfare, or Anti-Submarine Warfare missions. Other armament includes the Harpoon anti-ship cruise missile, the 5"/54 gun with improvements that integrate it with the AEGIS weapon system, and the Phalanx Close-in Weapon System for self-defense. |
