USS Hayler (DD-997)
USS ''Hayler'' (DD-997), the last ''Spruance''-class destroyer, was the first ship of the United States Navy to be named for Vice Admiral Robert W. Hayler (1891–1980).
==History==
For fiscal year 1978, Congress authorized the production of two additional ''Spruance''-class destroyers, though they funded only one. These were intended to be built as helicopter destroyers (DDH), provided they would not cost more than a standard ''Spruance''-class. Litton-Ingalls completed sketch design work for DDH-997, which moved the helicopter deck aft, stretching the length of the hangar and displacing the Sea Sparrow launcher to the top of the hangar. The design would have accommodated two SH-3 Sea Kings or four smaller SH-60 Seahawk or SH-2 Seasprite helicopters. While the prospective DDH-997 probably wouldn't have cost much more to build than a standard ''Spruance''-class, the detail design and engineering work required before the ship could be built would have been substantial (similar work for the ''Kidd''-class cost $110.8 million). This raised the cost of the DDH substantially above a standard ''Spruance''-class destroyer. While this additional cost might have been justified if the DDH was going to enter series production, it was difficult to justify for a single ship. Accordingly the Navy built ''Hayler'' to the same design as the rest of the class.
''Hayler'' was laid down on 20 October 1980 by Ingalls Shipbuilding, in Pascagoula, Miss.; launched on 2 March 1982; and commissioned on 5 March 1983.
