The first ship of this class, the “DDG 51 Arleigh Burke”, was activated 1991. Since then altogether 47 ships were built, further 14 are ordered (conditions 2005). The ships were manufactured in three variants:
- Flight I (51-71): 21 ships
- Flight II (72-78): , Electronics Flight IIA improved
- 7 ships (starting from 79): so far 19 ships, hangars for two SH-60 Seahawk helicopter, change of the armament
Table of contents
the ships of the Flight I are scarcely 153 meters long, the modified units of the Flight IIA of scarcely 155 meters. The ships of the Arleigh Burke class were the first ships of US Navy, which were developed according to the principles of the camouflage cap technology: The radar cross section was lowered to permit no right angles to the water surface whereby the broadside echo is avoided. But the broadsides were bended easily, used at deck no square, but diamandförmige forms for stairway hand rails, railing, Poller and the like. The mast was aft tilted attached not upright, but easily after.
The trunk is in the Gegensazt to the older destroyers rather short and broadly (relationship length: Spreads 7,9:1). Thus the Navy expected better sea-ability as well as maneuverability.
the drive of the class consists 100,000 wave HP of four gas turbines of the type LM-2500-30 of General Electric on two waves transfers. Thus the ships speeds of over 30 knots can reach, the range with an average speed of 20 knots lie with approx. 4,400 nautical miles. A increased maneuverability is reached by the employment by Controllable reversible pitch propellers, which can be tilted. The energy for the ship systems made available of three generators of Allison, which 2.5 megawatts out carry each.
the main armament of the ships consists of guided missiles, which are started from senkrechten Startvorrichtungen: The Flight i and II - ships have 90 starting cells, those of the Flight IIA 96. A VLS is on the Vordeck, second is installed on the afterdeck behind superstructures. In the cells BGM-109 Tomahawk - [cruise missiles]], standard Missile - are air defense rockets (as well as Sea Sparrow on the ships of the Flight IIA) and ASROC - rocket torpedoes.
On the ships of the Flight I are in addition two cans with four anti-ship missiles each AGM-84 Harpoon. On all ships two three-way of torpedo pipes with six torpedoes is to the employment against submarines type Mk. 46.
On the Vordeck is a 127mm cannon of the caliber of 54, starting from DDG-80 of the caliber 62. This cannon can to the attack on surface as well as airborne targets and to the Küstenbombardment on a range of approx. 24 km (by the larger caliber on the newer units special ammunition for large range can be used, be far fired those up to 100 kilometers can). The firing frequency is with 16 - 20 shots per minute, in the magazine 500 shells for the cannon store. For close range defense against approaching missiles stand before and behind superstructures ever a Phalanx CIWS with a firing frequency of up to 2000 shot per minute for order.
the Aegis combat system forms the core of the weapon system on the Arleigh Burke - for destroyers. It consists among other things of the SPY-1 radar system with that four flat radar antennas all directions at the same time searches and thus a constant monitoring possible makes. As detection and navigation radar a SPS-67 the north corporation is used, parallel to it a SPS-64.
The systems for electronic conduct of operations consist of the SLQ-32. The antennas, which are at superstructures, can be used for communications and electronic clearing-up as well as as jammers. Likewise to the SLQ-32-Paket that belongs Mark to 36 SRBOC, which shoot chaff and Flares into the air, which approaching rockets are to divert both with radar as well as with infrared seeker from the ship.
As sonar system serves the SQS-53, which is accommodated in the nose behind a fiber glass cap and both actively and passively can work.
the ships of the Flights I as well as II have electronics installed, which is necessary on their landing deck, in order to be able to take up helicopter LAMPS III. This covers above all the helicopters of the type Sikorsky SH-60 Seahawk. Starting from Flight IIA the afterdeck was increased and there a hangar for two helicopters type LAMPS III was furnished, so that two Seahawk can be embarked.
the destroyers of the Arleigh Burke class above all in addition planned and were built to protect carrier combat teams. Their Aegis combat system makes it valuable thereby particularly against air raids. Additionally the ships guided weapons can start against other surface units. All units are suitable for antisubmarine chase, whereby the later ships can begin by the hangar also unabhänig from aircraft carriers helicopters against submarines, while the early units are dependent always on the support of a transportation platform. The ships can be used owing to their Tomahawk cruise missiles also for attacks on land goals.
