The Arleigh Burke class of guided missile destroyers (DDGs) is a United States Navy class of destroyer built around the Aegis Combat System and the SPY-1D multifunction passive electronically scanned array radar. The class is named for Admiral Arleigh Burke, an American destroyer officer in World War II, and later Chief of Naval Operations. The lead ship, USS Arleigh Burke, was commissioned during Admiral Burke’s lifetime.
Knox-class frigates were United States Navy warships, originally laid down as ocean escorts (formerly called destroyer escorts), but were all redesignated as frigates on 30 June 1975, in the 1975 ship reclassification plan and their hull designation changed from DE to FF.
The Oliver Hazard Perry class is a class of guided-missile frigates named after the U.S. Commodore Oliver Hazard Perry, the hero of the naval Battle of Lake Erie. Also known as the Perry or FFG-7 (commonly “fig seven”) class, the warships were designed in the United States in the mid-1970s as general-purpose escort vessels inexpensive enough to be bought in large numbers to replace World War II-era destroyers and complement 1960s-era Knox-class frigates. In Admiral Elmo Zumwalt‘s “high low fleet plan”, the FFG-7s were the low capability ships with the Spruance-class destroyers serving as the high capability ships.
USS Freedom (LCS-1) is the lead ship of the Freedom-class littoral combat ship for the United States Navy. She is the third vessel to be so named after the concept of freedom. She is the design competitor produced by the Lockheed Martin consortium, in competition with the General Dynamics–designed USS Independence. She was officially accepted by the Supervisor of Shipbuilding Gulf Coast, on behalf of the US Navy, from the Lockheed Martin/Marinette Marine/Gibbs and Cox team, in Marinette, Wisconsin, on 18 September 2008.
