Leahy-class Guided Missile Cruiser

The American cruiser USS Leahy (CG-16) at sea.
The Leahy-class cruisers were a class of guided missile cruisers built for the United States Navy. They were originally designated as Destroyer Leaders (DLG), but in the 1975 cruiser realignment, they were reclassified as guided missile cruisers (CG).

They were a new "double-ender" class fitted with Terrier (later Standard ER) missile launchers fore and aft, and the first and only frigate class designed without a main gun battery for shore bombardment or ship-vs.-ship engagements—the gun armament was reduced in order to carry a larger missile load. One of the principal missions of these ships, like their predecessors the Farragut-class, was to form part of the anti-air and antisubmarine screen for carrier task forces, while also controlling aircraft from the carrier by providing vectors to assigned targets.

The ships carried over the propulsion plant of the Farragut-class, fitted into a longer hull designed with a knuckled “hurricane” bow that reduced plunging in a rough sea, thus keeping the forecastle dry as needed to operate the forward missile launcher. Other features included an expanded electrical plant and increased endurance. A major design innovation was the use of "macks"—combined masts and stacks—on which the radars could be mounted without smoke interference
