Development
In 1980 the US Navy initiated design studies with seven contractors. By 1983 the number of competitors had been reduced to three: Bath Iron Works, Todd Shipyards and Ingalls Shipbuilding. On 3 April 1985 Bath Iron Works received a US$321.9 million contract to build the first of class, USS Arleigh Burke. Gibbs & Cox was awarded the contract to be the lead ship design agent. The total cost of the first ship was put at US$1.1 billion, the other US$778 million being for the ship's weapons systems. She was laid down by the Bath Iron Works at Bath, Maine, on 6 December 1988, and launched on 16 September 1989 by Mrs. Arleigh Burke. The Admiral himself was present at her commissioning ceremony on 4 July 1991, held on the waterfront in downtown Norfolk, Virginia.
The "Flight IIA Arleigh Burke" ships have several new features, beginning with the Oscar Austin (DDG-79). Among the changes are the addition of two hangars for ASW helicopters, and a new, longer Mark 45 Mod 4 5-inch/62-caliber naval gun (fitted on Winston S. Churchill (DDG-81) and later ships). Later Flight IIA ships starting with USS Mustin have a modified funnel design that buries the funnels within the superstructure as a signature-reduction measure. TACTAS towed array sonar was omitted from flight IIA ships and they also lack Harpoon missile launchers. Ships from DDG-68 to DDG-84 have AN/SLQ-32 antennas that resemble V3 configuration similar to those deployed on Ticonderoga class cruisers, while the remainder have V2 variants externally resembling those deployed on some Oliver Hazard Perry class frigates. V3 has an active electronic countermeasures component while V2 is passive only. A number of Flight IIA ships were constructed without a Phalanx CIWS because of the planned Evolved Sea Sparrow Missile, but later the Navy decided to retrofit all IIA ships to carry at least one Phalanx CIWS by 2013.
USS Pinckney, USS Momsen, USS Chung-Hoon, USS Nitze, USS James E. Williams and USS Bainbridge have superstructure differences to accommodate the Remote Mine-hunting System (RMS). Mk 32 torpedo tubes were moved to the missile deck from amidships as well.

Famous quotes containing the word development:
“Sleep hath its own world,
And a wide realm of wild reality.
And dreams in their development have breath,
And tears, and tortures, and the touch of joy.”
—George Gordon Noel Byron (1788–1824)
“I do seriously believe that if we can measure among the States the benefits resulting from the preservation of the Union, the rebellious States have the larger share. It destroyed an institution that was their destruction. It opened the way for a commercial life that, if they will only embrace it and face the light, means to them a development that shall rival the best attainments of the greatest of our States.”
—Benjamin Harrison (1833–1901)
“To be sure, we have inherited abilities, but our development we owe to thousands of influences coming from the world around us from which we appropriate what we can and what is suitable to us.”
—Johann Wolfgang Von Goethe (1749–1832)
