The Ticonderoga class of guided-missile cruisers is a class of warships in the United States Navy, first ordered and authorized in the 1978 fiscal year. The class uses passive phased-array radar and was originally planned as a class of destroyers. However, the increased combat capability offered by the Aegis Combat System and the AN/SPY-1 radar system, together with the capability of operating as a flagship, were used to justify the change of the classification from DDG (guided missile destroyer) to CG (guided-missile cruiser) shortly before the keels were laid down for Ticonderoga and Yorktown.
Ticonderoga-class guided-missile cruisers are multi-role warships. Their Mk 41 VLS can launch Tomahawk cruise missiles to strike strategic or tactical targets, or fire long-range antiaircraft Standard missiles for defense against aircraft or anti-ship missiles. Their LAMPS III helicopters and sonar systems allow them to perform antisubmarine missions. Ticonderoga-class ships are designed to be elements of carrier battle groups or amphibious ready groups, as well as performing missions such as interdiction or escort.With upgrades to their AN/SPY-1 phased radar systems and their associated missile payloads as part of the Aegis Ballistic Missile Defense System, members of this class have, in successive tests, repeatedly demonstrated their proficiency as mobile anti-ballistic missile and anti-satellite weaponry platforms.
Of the 27 completed vessels, 19 were built by Ingalls Shipbuilding and eight by Bath Iron Works (BIW). All but one (Thomas S. Gates) of the ships in the class are named for noteworthy events in U.S. military history, and at least twelve share their names with World War II-era aircraft carriers. As of 2020, 22 ships are still active and expected to serve for 35 years since commissioning.
The Ticonderoga-class was originally ordered as guided missile destroyers, with the designation DDG-47. These ships were intended to be lower cost platforms for the new Aegis combat system by mounting the system on a hull based on that of the Spruance-classdestroyer. They would complement the much larger and more capable Strike Cruiser (CSGN) design. With the cancellation of the Strike Cruiser as well as the scaled down CGN-42 (Virginia-class cruiser hull) alternative, some of the requirements were transferred to the DDG-47, and the class was eventually re-designated as guided missile cruisers, CG-47, to reflect the additional flagship capabilities.Ships of the class from CG-52 onwards were equipped with the Mk. 41 vertical launch system.
As the Aegis combat system and the additional cruiser roles added substantial weight to the Spruance-derived hull, the design had limited growth potential in terms of weight and power margin. In the 1980s, a design study known as Cruiser Baseline (CGBL) was created to accommodate the capabilities of CG-52 (Mk. 41-equipped ships of the Ticonderoga class) on a hull with design and construction techniques matching the DDG-51 (Arleigh Burke-classdestroyer) for improved survivability and weight allowances.
Due to Budget Control Act of 2011 requirements to cut the Defense Budget for FY2013 and subsequent years, plans were being considered to decommission some of the Ticonderoga-class cruisers.For the U.S. Defense 2013 Budget Proposal, the U.S. Navy was to decommission seven cruisers early in fiscal years 2013 and 2014.
Because of these retirements, the U.S. Navy was expected to fall short of its requirement for 94 missile defense cruisers and destroyers beginning in FY 2025 and continuing past the end of the 30-year planning period. While this is a new requirement as of 2011, and the U.S. Navy has historically never had so many large missile-armed surface combatants, the relative success of the AEGIS ballistic missile defense system has shifted this national security requirement onto the U.S. Navy.Critics had charged that the early retirement of these cruisers would leave the Navy's ship fleet too small for the nation's defense tasks as the U.S. enacts a policy of "pivot" to the Western Pacific, a predominantly maritime theater. The U.S. House of Representatives passed a budget bill to require that these cruisers instead be refitted to handle the missile defense role.
By October 2012, the U.S. Navy had decided not to retire four of the cruisers early in order to maintain the size of the fleet. Four Ticonderoga-class cruisers, plus 21 Arleigh Burke-class destroyers, are scheduled to be equipped for antiballistic missile and antisatellite operations.
In March 2019, the Navy proposed decommissioning the six oldest of the active ships; Bunker Hill, Mobile Bay, Antietam, Leyte Gulf, San Jacinto and Lake Champlain, in 2021 and 2022, instead of dry-docking them for life-extension maintenance updates, as a cost-saving measure. This wouldn't technically be an "early retirement", as the ships would be at their originally planned 35-year life dates, but they would be able to serve longer with the upgrades. The proposal still needs the approval of Congress, which is usually hesitant to approve any actions that would reduce the size of the active combat fleet.
In December 2020 the U.S. Navy's Report to Congress on the Annual Long-Range Plan for Construction of Naval Vessels stated that the following ships were planned to be placed Out of Commission in Reserve;
The Ticonderoga-class cruiser's design was based on that of the Spruance-class destroyer.The Ticonderoga class introduced a new generation of guided missile warships based on the Aegis phased array radar that is capable of simultaneously scanning for threats, tracking targets, and guiding missiles to interception. When they were designed, they had the most powerful electronic warfare equipment in the U.S. Navy, as well as the most advanced underwater surveillance system. These ships were one of the first classes of warships to be built in modules, rather than being assembled from the bottom up.
The greater size and equipment on the CG-47–class warships increased displacement from 6,900 tons of the DD-963–class destroyers to 9,600 tons of displacement for the heavier cruisers. Aegis cruisers can steam in any ocean and conduct multi-warfare operations anywhere. Some cruisers reported some structural problems in early service after extended periods in extremely heavy seas; they were generally corrected from the late 1980s to the mid-1990s. Several ships had superstructure cracks, which were repaired.[ citation needed ]
These ships' superstructures were a modification of that on the Spruance-class destroyers and were required to support two deck-houses (one forward for antennas forward and starboard), and the aft deck-house housed the aft and port antenna arrays. The later Arleigh Burke-class Aegis destroyers are designed from the keel up to carry the SPY-1D radars and have them all clustered together on the forward deck-house, saving space and weight and simplifying cooling requirements. Radar support equipment is closer together, minimizing cable runs and concentrating support equipment.[ citation needed ]
Operations research was used to study manpower requirements on the Ticonderoga class. It was found that four officers and 44 enlisted sailors could be removed from the ship's complement by removing traditional posts that had been made obsolete.However, manpower savings achieved by eliminating the very manpower-intensive Mk 26 guided missile system and replacing it with the far more capable and versatile MK 41 Vertical Launching System (VLS) were harder to emulate with the Mk 45 127 mm (5") gun systems. The Aegis Cruisers are "double-enders", and along with the Zumwalt-class, are the only surface combatants in the fleet that can employ two large caliber guns simultaneously.
In addition to the added radar capability, the Ticonderoga-class ships built after USS Thomas S. Gates included two Mark 41 Vertical Launching Systems (VLS). The two VLS allow the ship to have 122 missile storage and launching tubes that can carry a wide variety of missiles, including the Tomahawk cruise missile, Standard surface-to-air missile, Evolved Sea Sparrow surface-to-air missile, and ASROC antisubmarine warfare (ASW) guided rockets. More importantly, the VLS enables all missiles to be on full standby at any given time, shortening the warship's response time before firing. The original five ships (Ticonderoga, Yorktown, Vincennes, Valley Forge, and Thomas S. Gates) had Mark 26 twin-arm launchers that limited their missile capacity to a total of 88 missiles, and that could not fire the Tomahawk missile. After the end of the Cold War, the lower capabilities of the original five warships limited them to duties close to the home waters of the United States.
A standard missile loadout for a Ticonderoga cruiser is 80 SM-2 SAMs, 16 ASROC anti-submarine rockets, and 26 Tomahawk cruise missiles.
Originally, the U.S. Navy had intended to replace its fleet of Ticonderoga-class guided-missile cruisers with cruisers produced as part of the CG(X) missile cruiser program; however, severe budget cuts from the 21st century surface combatant program coupled with the increasing cost of the Zumwalt-class guided missile destroyer program resulted in the CG(X) program being canceled. The Ticonderoga-class cruisers were instead to be replaced by Flight III Arleigh Burke-class guided-missile destroyers.
All five of the twin-arm (Mk-26) cruisers have been decommissioned. In 2003, the newer 22 of the 27 ships (CG-52 to CG-73) in the class were upgraded to keep them combat-relevant, giving the ships a service life of 35 years.In the years leading up to their decommissioning, the five twin-arm ships had been assigned primarily home-waters duties, acting as command ships for destroyer squadrons assigned to the eastern Pacific and western Atlantic areas.
As of July 2013 [update] 12 cruisers have completed hull, mechanical, and electrical (HM&E) upgrades and 8 cruisers have had combat systems upgrades. These include an upgrade of the AEGIS computational system with new computers and equipment cabinets, the SPQ-9B radar system upgrade introducing an increased capability over just gunfire control, some optical fiber data communications and software upgrades, and modifications to the vertical launch system allowing two 8 cell modules to fire the RIM-162 ESSM. The most recent upgrade packages will include SM-6 and Naval Integrated Fire Control – Counter Air (NIFC-CA) capability. Another upgrade is improving the SQQ-89A(V)15 sonar with a multi-function towed array. Hull, sonar, radar, electrical, computer, and weapons systems upgrades can cost up to $250 million per ship.
In its 2015 budget request, the Navy outlined a plan to operate 11 cruisers, while the other 11 were upgraded to a new standard. The upgraded cruisers would then start replacing the older ships, which would be retired starting in 2019.This would retain one cruiser per CVN group to host the group's air warfare commander, a role for which the DDGs do not have sufficient facilities. Flight III Arleigh Burke destroyers equipped with the Air Missile Defense Radar give enhanced coverage, but putting the radar on standard DDG hulls does not allow enough room for extra staff and command and control facilities for the air warfare commander; DDGs can be used tactically for air defense, but they augment CGs that provide command and control in a battle group and are more used for other missions such as defending other fleet units and keeping sea lanes open. Congress opposed the plan on the grounds that it makes it easier for Navy officials to completely retire the ships once out of service; the Navy would have to retire all cruisers from the fleet by 2028 if all are kept in service, while deactivating half and gradually returning them into service could make 11 cruisers last from 2035 to 2045. There is no current CG replacement program, as most funding is committed to the Columbia-class submarine, so work on a new cruiser is expected to begin in the mid-2020s, and begin fielding by the mid-2030s.

One ship of the class, Vincennes, achieved notoriety in 1988 when, in the midst of a running gun battle with Iranian Revolutionary Guard gunboats, she shot down Iran Air Flight 655, resulting in 290 civilian deaths.The commanding officer of USS Vincennes, William C. Rogers III, believed the airliner to be an Iranian Air Force F-14 Tomcat fighter jet on an attack vector, based on mis-reported radar returns. The investigation report recommended that the AEGIS large screen display be changed to allow the display of altitude information on plots, and that stress factors on personnel using AEGIS be studied.
On 14 February 2008, the United States Department of Defense announced that Lake Erie would attempt to hit the dead satellite USA-193 over the North Pacific Ocean just before it would burn up on reentry.On 20 February 2008, at approximately 22:30 EST (21 February, 03:30 UTC), an SM-3 missile was fired from Lake Erie and struck the satellite. The military intended that the missile's kinetic energy would rupture the hydrazine fuel tank allowing the toxic fuel to be consumed during re-entry. The Department of Defense confirmed that the fuel tank had been directly hit by the missile.

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.
The Aegis Combat System is an American integrated naval weapons system developed by the Missile and Surface Radar Division of RCA, and now produced by Lockheed Martin. It uses powerful computer and radar technology to track and guide weapons to destroy enemy targets.
The Spruance-class destroyer was developed by the United States to replace the many World War II–built Allen M. Sumner- and Gearing-class destroyers and was the primary destroyer built for the U.S. Navy during the 1970s and 1980s.
The Charles F. Adams class is a ship class of 29 guided missile destroyers (DDG) built between 1958 and 1967. Twenty-three destroyers were built for the United States Navy, three for the Royal Australian Navy, and three for the West German Bundesmarine. The design of these ships was based on that of Forrest Sherman-class destroyers, but the Charles F. Adams class were the first class designed to serve as guided missile destroyers. 19 feet (5.8 m) of length was added to the center of the design of the Forrest Sherman class to carry the ASROC launcher. The Charles F. Adams-class destroyers were the last steam turbine-powered destroyers built for the U.S. Navy. Starting with the later Spruance-class destroyers, all U.S. Navy destroyers have been powered by gas turbines. Some of the destroyers of the Charles F. Adams class served during the blockade of Cuba in 1962 and during the Vietnam War. Destroyers of the Royal Australian Navy served during the Vietnam War and Gulf War.
USS John Paul Jones (DDG-53) is the third Arleigh Burke-class guided missile destroyer and the first ship of the class homeported on the west coast. She is named after American Revolutionary War naval captain John Paul Jones and the second ship to be so named. She was built at Bath Iron Works in Bath, Maine. The ship is currently part of Destroyer Squadron 23, and administratively reports to Commander, Naval Surface Forces Pacific.
The Virginia-class nuclear guided-missile cruisers, also known as the CGN-38 class, were a series of four double-ended nuclear-powered guided-missile cruisers commissioned in the late 1970s to 1980, which served in the United States Navy until the mid-to-late 1990s. They were the final class of nuclear-powered cruisers completed and the last ships ordered as Destroyer Leaders under the pre-1975 classification system.
The Zumwalt-class destroyer is a class of three United States Navy guided missile destroyers designed as multi-mission stealth ships with a focus on land attack. It is a multi-role class that was designed for secondary roles of surface warfare and anti-aircraft warfare and originally designed with a primary role of naval gunfire support. The class design emerged from the DD-21 "land attack destroyer" program as "DD(X)" and was intended to take the role of battleships in meeting a congressional mandate for naval fire support. The ship is designed around its two Advanced Gun Systems, their turrets and magazines, and unique Long Range Land Attack Projectile (LRLAP) ammunition. LRLAP procurement was cancelled, rendering the guns unusable, so the Navy re-purposed the ships for surface warfare.
The Kongō class of guided missile destroyers in the Japan Maritime Self-Defense Force are equipped with the Aegis Combat System, and is the first of few ship classes outside the United States to have that capability. Following a decision made in December 2003, Japan is upgrading their Kongo-class destroyers with Aegis Ballistic Missile Defense System. The upgrade involves a series of installations and flight tests to take place from 2007 to 2010. JS Kongo was the first ship to have the BMD upgrade installed.
The Kidd-class destroyers were a series of four guided missile destroyers (DDGs) based on the Spruance class. In contrast to their predecessor's focus on anti-submarine warfare, the Kidds were designed as more advanced multipurpose ships with the addition of considerably enhanced anti-aircraft capabilities. Originally ordered for the former Imperial Iranian Navy, the contracts were canceled when the 1979 Iranian Revolution began, and the ships were completed for the United States Navy. They were decommissioned in 1999 and sold to the Republic of China Navy as the Kee Lung class.
The CG(X) program, also known as the Next Generation Cruiser program, was a United States Navy research program to develop a replacement vessel for its 22 Ticonderoga-class cruisers. Original plans were for 18–19 ships, based on the 14,500 ton Zumwalt-class destroyer with additional ballistic missile defense and area air defense for a carrier group. These vessels were to enter service beginning in 2017. The program was ended in 2010 with its mission to be fulfilled by the successor to the Flight III Arleigh Burke–class destroyers.
The Tartar Guided Missile Fire Control System is an air defense system developed by the United States Navy to defend warships from air attack. Since its introduction the system has been improved and sold to several United States allies.
A strike cruiser was a proposal from DARPA for a class of cruisers in the late 1970s. The proposal was for the Strike Cruiser to be a guided missile attack cruiser with a displacement of around 17,200 long tons (17,500 t), armed and equipped with the Aegis combat system, the SM-2, Harpoon anti-ship missile, the Tomahawk missile, and the Mk71 8-inch gun.
The Sejong the Great-class destroyers, also known as KDX-III, are three guided missile destroyers of the Republic of Korea Navy (ROKN). The ROKN has deployed three ships with an option for three more which was taken up in December 2013.
New Threat Upgrade (NTU) was a United States Navy program to improve and modernize the capability of existing cruisers and destroyers equipped with Terrier and Tartar anti-aircraft systems, keeping them in service longer. It was a key component of then-President Ronald Reagan's 600-ship Navy plan.
Rear Admiral Wayne E. Meyer is regarded as the "Father of Aegis" for his 13 years of service as the Aegis Weapon System Manager and later the founding project manager of the Aegis Shipbuilding Project Office. He retired from the United States Navy in 1985 as the Deputy Commander for Weapons and Combat Systems, Naval Sea Systems, Naval Sea Systems Command and Ordnance Officer of the Navy.
SC-21 was a research and development program started in 1994 intended to design land attack ships for the United States Navy. A wide variety of designs were created and extensively examined, including an arsenal ship with 500 cruise missiles. Eventually a "tumblehome" design of around 16,000 tons with two long-range guns and 128 missile tubes was selected as the DD-21, the Destroyer for the 21st century. The program ended in November 2001, with a version of the DD-21 emerging as the DD(X) or Zumwalt class destroyer. It was envisaged that the DD-21 hull would be used for a future air defense cruiser (CG-21), which then eventually evolved into the CG(X) program.
AN/SPQ-9A,, is a United States Navy multi-purpose surface search & fire control radar used with the Mk-86 gun fire-control system. It is a two dimensional surface-search radar, meaning it provides only range and bearing but not elevation. It is intended primarily to detect & track targets at sea level, on the surface of the water for either gun fire engagement or navigation. It can however, also detect and track low altitude air targets.
The RIM-66 Standard MR (SM-1MR/SM-2MR) is a medium-range surface-to-air missile (SAM), with a secondary role as anti-ship missile, originally developed for the United States Navy (USN). A member of the Standard Missile family of weapons, the SM-1 was developed as a replacement for the RIM-2 Terrier and RIM-24 Tartar that were deployed in the 1950s on a variety of USN ships. The RIM-67 Standard (SM-1ER/SM-2ER) is an extended range version of this missile with a solid rocket booster stage.
The RIM-67 Standard ER (SM-1ER/SM-2ER) is an extended range surface-to-air missile (SAM) and anti ship missile originally developed for the United States Navy (USN). The RIM-67 was developed as a replacement for the RIM-8 Talos, a 1950s system deployed on a variety of USN ships, and eventually replaced the RIM-2 Terrier as well, since it was of a similar size and fitted existing Terrier launchers and magazines. The RIM-66 Standard MR was essentially the same missile without the booster stage, designed to replace the RIM-24 Tartar. The RIM-66/67 series thus became the US Navy's universal SAM system, hence the "Standard Missile" moniker.
The Mark 41 Vertical Launching System is a shipborne missile canister launching system which provides a rapid-fire launch capability against hostile threats. The Vertical Launch System (VLS) concept was derived from work on the Aegis Combat System.
