the Arleigh Burke class are actually larger and more heavily armed than most previous ships classified as guided missile cruisers, due to their massive size at long, displacement (9200 tons) and armament of over 90 missiles. Guided-missile destroyers are destroyers designed to launch guided missiles. Many are also equipped to carry out anti-submarine, anti-air, and anti-surface operations. The NATO standard designation for these vessels is DDG. Nations vary in their use of destroyer D designation their hull pennant numbering, either prefixing, or dropping it altogether. The U.S. Navy has adopted the classification DDG in the American hull classification system. In addition to the guns that destroyers have, a guided-missile destroyer is usually equipped with two large missile magazines, usually in vertical-launch cells. Some guided-missile destroyers contain powerful radar systems, such as the United States’ Aegis Combat System, and may be adopted for use in an anti-missile or ballistic-missile defense role. This is especially true of navies that no longer operate cruisers, as other vessels must be adopted to fill in the gap. (68 in active service of 87 planned) (2 in active service, 1 under construction) Frigates Frigates FF or FFG (according to the modern classification of U.S. navy warships) are smaller ships than destroyers. They are designed primarily to protect other ships (such as merchant convoys), and perform some Anti-Submarine Warfare duties. They are cheaper but of more limited capability than destroyers. The last active class of frigates in the US Navy was the , decommissioned in September 2015, leaving the navy no active frigates. On 15 January 2015, U.S. Navy Secretary Ray Mabus announced that ships of the Littoral Combat Ship (LCS) classes built in the future would be re-classified as "frigates". This would apply only to the future variations of these ships. Current ships will retain the LCS classification unless and until they are upgraded to the standards of the newer ships. On 30 April 2020, the US Navy awarded a contract to design and produce the next generation small surface combatant, the Guided Missile Frigate (FFG(X)). The contract for detail design and construction (DD&C) of up to 10 Guided Missile Frigates (consisting of one base ship and nine option ships) was awarded to Fincantieri Marinette Marine Corporation (MMC) of Marinette, Wisconsin. The FFG(X) will have multi-mission capability to conduct air warfare, anti-submarine warfare, surface warfare, electronic warfare, and information operations. Specifically FFG(X) will include an Enterprise
