Arleigh Burke-class destroyer

The ''Arleigh Burke'' class of guided-missile destroyers (DDGs) is a United States Navy class of destroyer centered around the Aegis Combat System and the SPY-1D multi-function passive electronically scanned array radar. The class is named after Arleigh Burke, an American destroyer admiral in World War II and later Chief of Naval Operations. With an overall length of , displacement ranging from 8,300 to 9,700 tons, and weaponry including over 90 missiles, the ''Arleigh Burke''-class destroyers are larger and more heavily armed than many previous classes of guided-missile cruisers.

These warships are multi-mission destroyers able to conduct anti-aircraft warfare with Aegis and surface-to-air missiles; tactical land strikes with Tomahawk missiles; anti-submarine warfare (ASW) with towed array sonar, anti-submarine rockets, and ASW helicopters; and anti-surface warfare (ASuW) with ship-to-ship missiles and guns. With upgrades to their AN/SPY-1 radar systems and their associated missile payloads as part of the Aegis Ballistic Missile Defense System, as well as the introduction of the AN/SPY-6 radar system, the class has also evolved capability as mobile anti-ballistic missile and anti-satellite platforms.

The lead ship of the class, , was commissioned during Admiral Burke's lifetime on 4 July 1991. With the decommissioning of the last , , on 2005, the ''Arleigh Burke''-class ships became the U.S. Navy's only active destroyers until the became active in 2016. The ''Arleigh Burke'' class has the longest production run of any U.S. Navy surface combatant. seventy-four are active, with twenty-five more planned to enter service.

Characteristics

Variants

The ''Arleigh Burke''-class destroyer has four variants, referred to as "Flights". Newer Flights incorporate technological advancements.
*Flight I: DDGs 51–71
*Flight II: DDGs 72–78
*Flight IIA: DDGs 79–124 and DDG-127
*Flight III: DDGs 125–126 and DDG-128 onwards

Structure

The ''Arleigh Burke''-class ships are among the largest destroyers built in the United States; only the , (), and classes () are longer. The ''Arleigh Burke'' class was designed with a new large, water-plane area-hull form characterized by a wide flaring bow, which significantly improves seakeeping ability and permits high speed in high sea states. The class's design incorporates stealth techniques, such as the angled (rather than traditional vertical) surfaces and the raked tripod mainmast, which make the ship more difficult to detect by radar.Gardiner and Chumbley 1995, p. 592Baker 1998, p. 1020

Its designers incorporated lessons from the , which the Navy deemed too expensive to continue building and difficult to upgrade further. For these destroyers, the U.S. Navy returned to all-steel construction, except the mast made of aluminum. The ''Ticonderoga''s had combined a steel hull with a superstructure made of lighter aluminum to reduce top weight, but the lighter metal proved vulnerable to cracking. Aluminum is also less fire-resistant than steel; a 1975 fire aboard gutted her aluminum superstructure. Battle damage to Royal Navy ships exacerbated by their aluminum superstructures during the 1982 Falklands War supported the decision to use steel. Other lessons from the Falklands War led to the Navy's decision to protect the ''Arleigh Burke'' class's vital spaces with double-spaced steel layers, which create a buffer against anti-ship missiles (AShMs), and Kevlar spall liners. A design study called " Cruiser Baseline" was made for a ship that would incorporate the capabilities of the VLS-capable ''Ticonderoga'' class on a hull and superstructure designed to the same standards as the ''Arleigh Burke'', although this study was for analytical purposes only and no such ship was built.

Passive defenses

''Arleigh Burke'' destroyers are equipped with AN/SLQ-32 electronic warfare (EW) suites that provide electronic support. Vessels with the SLQ-32(V)3, SLQ-32(V)6, or SLQ-32(V)7 variant can jam radars.

The destroyers have Mark 36 infrared and chaff decoy launchers, as well as Nulka decoy launchers, for spoofing incoming AShMs.Wertheim 2005, p. 913 For defeating incoming torpedoes, the class has two AN/SLQ-25 Nixie towed countermeasures.Polmar 2013, p. 142 The ships' Prairie-Maskers can reduce their radiated noise.Wertheim 2005, p. 948

A collective protection system makes the ''Arleigh Burke'' class the first U.S. warships designed with an air-filtration system against nuclear, biological, and chemical warfare (NBC). Other NBC defenses include double air-locked hatches, pressurized compartments, and an external countermeasure washdown system. The class's electronics are hardened against electromagnetic pulses. Fire suppression equipment includes water sprinklers in the living quarters and combat information center (CIC).

Weapon systems

The ''Arleigh Burke'' class are multi-mission ships with numerous combat systems, including anti-aircraft missiles, land attack missiles, ship-to-ship missiles, and an anti-submarine warfare (ASW) system. Missiles are stored in and fired from Mark 41 Vertical Launching System (VLS) cells; with 90 cells on Flights I–II and 96 cells starting with Flight IIA,Wertheim 2005, p. 946 the ''Arleigh Burke''s are more heavily armed than many preceding guided-missile cruiser classes. The ''Arleigh Burke''-class destroyer is equipped with the Aegis Combat System, which combines information from the ship's sensors to display a coherent image of the environment and guides weapons to targets using advanced tracking and fire control.

Their main radar differs from traditional mechanically rotating radars. Instead, Aegis uses the AN/SPY-1D passive electronically scanned array (or the AN/SPY-6 active electronically scanned array on Flight III ships), which allows continual tracking of targets simultaneous to area scans. The system's computer control also allows centralization of the previously separate tracking and targeting functions. The system is resistant to electronic countermeasures.Polmar 2013, p. 127

The Standard Missile SM-2MR/ ER and SM-6 provide area air defense, though they may also be used in a secondary anti-ship role. The SM-2 uses semi-active radar homing (SARH); up to three targets may be simultaneously intercepted as the ''Arleigh Burke''s have three AN/SPG-62 fire-control radars for terminal target illumination. The SM-6, which provides over-the-horizon defense, and the SM-2 Block IIIC feature a dual-mode seeker with active radar homing (ARH) capability; they do not have to rely on external illumination, so more targets may be intercepted simultaneously.

Flights IIA and III—and modernized Flight I and II ships—can carry RIM-162 Evolved SeaSparrow Missiles (ESSMs), which provide medium-range air defense and are also capable of targeting other ships. ESSM is small enough to be quad-packed into a single Mk 41 VLS cell. ESSM Block 1 uses SARH, guided similarly to older SM-2s. ESSM Block 2, which achieved initial operating capability (IOC) in 2021, features a dual-mode seeker with ARH capability.

The SM-3, SM-6, and SM-2ER Block IV provide Ballistic Missile Defense (BMD), the SM-3 being an exoatmospheric interceptor and the latter two having terminal phase anti-ballistic capability. So vital has the Aegis BMD role become that all ships of the class are being updated with BMD capability. By January 2023, there were 51 BMD-capable ''Arleigh Burke''-class destroyers. Flight III ships have been delivered since 2023 with AN/SPY-6(V)1 radars and improved BMD capabilities; Flight IIA ships are also planned to receive these upgrades with AN/SPY-6(V)4 radar retrofits.

Flights I and II carry two stand-alone Harpoon anti-ship missile launchers for a total of four or eight Harpoons,Wertheim 2005, p. 947 providing an anti-ship capability with a range in excess of . During Exercise RIMPAC 2024, DDG-62, a Flight I ship, launched a Naval Strike Missile (NSM); the launchers for the Harpoons were removed to make room for the NSM's proprietary launch boxes. The Long Range Anti-Ship Missile could be used from the class's VLS, as it has been tested with the Self Defense Test Ship.

The class can perform tactical land strikes with VLS-launched Tomahawks. With the development of the Tomahawk Block V, all existing Block IV Tomahawks carried will be converted to the Block V. The Tomahawk Block Va version is called the Maritime Strike version, and it provides anti-ship capability in addition to its land attack role. The Block Vb version features the Joint Multi-Effects Warhead System for hitting a wider variety of land targets.

''Arleigh Burke''-class ships have the AN/SQQ-89 ASW combat system, which is integrated with Aegis. It encompasses the AN/SQS-53C bow-mounted sonar and a towed array sonar, though several Flight IIA ships do not have a towed array. The towed array is either the AN/SQR-19 Tactical Towed Array Sonar (TACTAS) or the newer TB-37U Multi-Function Towed Array (MFTA). The ships can carry standoff RUM-139 vertical launch anti-submarine rockets. A Mark 32 triple torpedo tubes mount on each side of the ship can fire Mark 46, Mark 50, or Mark 54 lightweight torpedoes for short-range ASW. The ships can detect anti-ship mines at a range of about 1,400 meters.

All ships of the class are fitted with at least one Phalanx close-in weapon system (CIWS), which provides point defense against air and surface threats. Eight ships ( DDG-51, DDG-64, DDG-71, DDG-75, DDG-78, DDG-80, DDG-84, DDG-117) are equipped with one SeaRAM CIWS for improved self-defense. ''Arleigh Burke''s can also carry two 25 mm Mk 38 machine gun systems, one on each side of the ship, designed to counter fast surface craft. There are numerous mounts for crew-served weapons like the M2 Browning.

Located on the forward deck is the 5-inch (127 mm) Mark 45 gun. Directed by the Mark 34 Gun Weapon System, it can be used in anti-ship, anti-air, and naval gunfire support (NGFS) roles. It can fire 16–20 rounds per minute and has a range of . ''Arleigh Burke''s can stow 680 5-inch rounds.

As of 2023, six destroyers ( DDG-100, DDG-104, DDG-105, DDG-106, DDG-111, DDG-113) are equipped with the Optical Dazzling Interdictor, Navy (ODIN), a directed energy weapon that can target unmanned vehicles. DDG-88 is equipped with the higher-power High Energy Laser with Integrated Optical-dazzler and Surveillance (HELIOS).

Aircraft

Flights IIA and III have two hangars for stowing MH-60 helicopters. Their Light Airborne Multi-Purpose System (LAMPS) helicopter system improves the ship's capabilities by enabling the MH-60 to monitor submarines and surface ships, launch torpedoes and missiles against them, and provide fire support during insertions/ extractions with machine guns and Hellfire anti-armor guided missiles. The helicopters also serve in a utility role, able to perform vertical replenishment, search and rescue, medical evacuation, communications relay, and naval gunfire spotting and controlling.

In March 2022, an ''Arleigh Burke'' destroyer was deployed with an AAI Aerosonde unmanned aerial vehicle (UAV). The aircraft is under demonstration for Flight I and II ships, which do not have accommodations for permanently storing helicopters. The Aerosonde has a small enough footprint to be stowed on those destroyers. It can perform missions such as intelligence, surveillance, and reconnaissance at a much lower cost than manned helicopters.

Development

Origins and Flight I

The Chief of Naval Operations (CNO) from 1970 to 1974, Admiral Elmo Zumwalt, sought to improve the U.S. Navy through modernization at minimal cost. Zumwalt's approach to the fleet was a "high-low mix"—a few high-end, high-cost warships supplemented by numerous low-end, low-cost warships. The introduction of the Aegis-equipped ''Ticonderoga''-class cruiser in the early 1980s filled the high end. The Navy started work to develop a lower-cost Aegis-equipped vessel to fill the low end and replace the aging Gardiner and Chumbley 1995, pp. 550–551Friedman 1982, pp. 388–389 and ''Farragut'' class destroyers, along with the ''Leahy'' and ''Belknap'' class cruisers.

In 1980, the U.S. Navy initiated design studies with seven contractors. By 1983, the number of competitors had been reduced to three: Bath Iron Works, Ingalls Shipbuilding, and Todd Shipyards. On 3 April 1985, Bath Iron Works received a US$321.9 million contract to build the first of the class, USS ''Arleigh Burke''. Gibbs & Cox was awarded the contract to be the lead ship design agent. The Navy contracted Ingalls Shipbuilding to build the second ship.

Political restraints led to design restrictions, including the absence of helicopter hangars, a displacement limit of 8,300 tons, and a 50-foot shorter hull than the ''Ticonderoga'''s. To compensate for the limited length, a wide flaring bow was incorporated to maintain favorable seakeeping characteristics, and the originally-planned 80,000 shaft horsepower (shp) LM2500 gas turbines were upgraded to 100,000 shp. No main gun was included in the original design, later amended to include an OTO Melara 76 mm, before finally selecting the 5-inch/54-caliber Mark 45. Despite their constraints, the designers benefited from insight gained from previous classes; for example, they chose an all-steel superstructure to improve survivability.

The total cost of the first ship was $1.1 billion, the other $778 million being for the ship's weapons systems. USS ''Arleigh Burke'' was laid down by the Bath Iron Works at Bath, Maine, on 6 December 1988, and launched on 16 September 1989 by Mrs. Arleigh Burke. The Admiral himself was present at her commissioning ceremony on 4 July 1991, held on the waterfront in downtown Norfolk, Virginia. Orders for Flight I ships continued through 1995.

Flight II

The Flight II iteration of the class was introduced in FY1992. The incorporation of the AN/SRS-1A(V) Combat Direction Finding enhanced detection of signals. The TADIX-B, JTIDS Command and Control Processor, and Link 16 improved communication with other assets. The SLQ-32 EW suite was upgraded to (V)3, and the SPS-67(V)3 surface search radar was upgraded to (V)5. Flight II also gained the capability to launch and control the SM-2ER Block IV. An expansion of fuel capacity slightly increased the displacement.Saunders 2015, p. 940

Flight III (1988)

Work on a much improved design known as Flight III began in 1988, to be first procured in FY 1994. This design had a 40 foot plug amidships to provide greater volume for combat systems, and was of a flush deck configuration. Its main improvements were in ASW performance, with hangars and support facilities for two SH-60B LAMPS III helicopters and compatibility with the under development RUM-125 Sea Lance. The ship's AAW performance was also enhanced, with 32 additional VLS cells forwards, Cooperative Engagement Capability (CEC), integrated Anti-Ship Missile Defense (ASMD) systems, and air warfare commander facilities to coordinate the actions of a CSG in air defense, as was found on the ''Ticonderoga''-class cruisers. The new AN/SAR-8 also provided the ship with an infrared search and track capability, and fiber optical cables replaced copper to improve bandwidth and reduce weight gain. To power the increased equipment load, the Allison 501-K34 ship service gas turbine generators were uprated from 2,500 kW each to 3,000 kW. Incorporating lessons learned with the attacks on USS ''Stark'' in 1987 and USS ''Samuel B. Roberts'' in 1988, five blast-resistant bulkheads were incorporated into the ship to improve damage containment. The ship was designed with several upgrades to be added on later ships, including the AN/SQQ-89I Block III hull and towed sonar, intercooled recuperated gas turbines, and an improved fire control system. As tensions decreased throughout 1989 and 1990 however, there became less of a need for such a high performance ship, and Flight III was canceled in December 1990 as a cost reduction measure.

Flight IIA

Work on Flight IIA began shortly after Flight III's demise, with the Destroyer Variant (DDV) study beginning in mid 1991. These designs were intended to be far more economical than Flight III in light of the less intense warfare they were expected to be used in while still retaining Flight III's helicopter facilities. Due to the expectation of lower intensity warfare, the Harpoon missile launchers and AN/SQR-19 TACTAS were to be removed, with reinstallation possible given two years notice. The Phalanx CIWS systems were to be deleted as well, pending the availability of RIM-162 ESSM. Most of the resultant designs from this study placed an increased emphasis on land attack, littoral warfare, and reduced operating costs. Almost all featured a reduced cell count and some even using a smaller hull. Despite this emphasis during the study phase, the selected design was one that did not compromise on the ship's existing performance beyond the mandated deletion of Harpoon and TACTAS.

Flight IIA was first procured in FY 1994, and featured numerous improvements used on Flight III. The two hangars and support facilities for LAMPS helicopters remained, albeit located differently in two hangars outboard of the aft VLS module. To accommodate the hangars, the length was increased to , and the rear-facing SPY-1D arrays are mounted one deck (eight feet) higher to prevent a blind spot,Polmar 2013, pp. 141–142 as had been done on Flight III for the same reason. CEC, fiber optical data cables,Saunders 2015, p. 942 blast-resistant bulkheads, and uprated ship service generators were also carried over from Flight III. New to Flight IIA was the Kingfisher mine detection system, the deletion of the onboard missile reloading cranes and their replacement with six additional VLS cells, and redesigned propellers to reduce cavitation.Wertheim 2005, p. 945 Phalanx was temporarily kept due to developmental issues with ESSM, the forward system being removed starting with . While these ships initially lacked a towed sonar array, some have been refit with them after production of the class restarted in the 2010s.

Starting with , the longer 5-inch/62-caliber (127 mm) Mark 45 Mod 4 gun was installed. Later Flight IIA ships starting with use the BridgeMaster E as their navigation radar instead of the AN/SPS-73(V)12. Subsequent Flight IIA ships employ additional signature-reduction measures: the hangars of DDG-86 onwards are made of composite materials, and the exhaust funnels of DDG-89 onwards are shrouded by the superstructure. The use of the improved SPY-1D(V) radar, starting with , enhances the ships' ability to filter out clutter and resist electronic attack.

Several Flight IIA ships were constructed without any Phalanx CIWS because of the planned Evolved SeaSparrow Missile; the Navy had initially decided that ESSM made Phalanx redundant. However, the Navy later changed its mind and decided to retrofit all IIA ships to carry at least one Phalanx CIWS by 2013.

DDGs 91–96 (USS ''Pinckney'', , , , , and ) were built with superstructure differences to accommodate the AN/WLD-1 Remote Minehunting System (RMS). However, only ''Pinckney'', ''Momsen'', and ''Bainbridge'' were installed with the system before the RMS program was canceled.

Modernization

Efforts to modernize the ''Arleigh Burke'' class began amid congressional concerns over the retirement of the . In 1996, the Navy began a program to field the Extended Range Guided Munition (ERGM) for the DDG-51 class. The ERGM was to extend the class's 5-inch Mark 45 gun range to . It necessitated a modification of the gun; the 62-caliber Mark 45 Mod 4 was created and installed on DDG-81 and onwards in anticipation of the ERGM. However, the ERGM was canceled in 2008.

The current DDG-51 modernization program is designed to provide mid-life upgrades to ensure the destroyers remain effective with service lives of at least 35 years. Modernization of existing ships provides commonality with in-production ships. The program's goals are reduced manning, increased mission effectiveness, and reduced total cost. Mid-life modernization of Flight I and II ships is done in two phases: the first phase updates the hull, mechanical, and electrical (HM&E) systems, while the second phase focuses on Aegis Combat System upgrades and introduces an Open Architecture Computing Environment (OACE). By 2017, modernization technologies were introduced to production ships, and the Navy started modernization of Flight IIA ships through a single process combining both phases of upgrading. The capabilities of modernized destroyers include CEC, Integrated Air and Missile Defense (IAMD), ESSM support, improved electronic support with Surface Electronic Warfare Improvement Program (SEWIP) Block 2, improved data processing with Boeing's Gigabit Ethernet Data Multiplex System, and improvements to littoral warfare.

In July 2010, BAE Systems announced it had been awarded a contract to modernize 11 ships. In May 2014, USNI News reported that 21 of the 28 Flight I and II ''Arleigh Burke''-class destroyers would not receive the full mid-life upgrade that included electronics and Aegis Baseline 9 software for SM-6 compatibility; instead, they would retain the basic BMD 3.6.1 software in a $170 million upgrade concentrating on HM&E systems, and on some ships, their anti-submarine suite. Seven Flight I ships—DDGs 51–53, 57, 61, 65, 69—received the full $270 million Baseline 9 upgrade. Deputy of surface warfare Dave McFarland said that this change was due to the budget cuts in the Budget Control Act of 2011.

In 2016, the Navy announced it would begin outfitting 34 Flight IIA ''Arleigh Burke''s with a hybrid-electric drive (HED) to lower fuel costs. The four LM2500 gas turbines of the class are most efficient at high speeds; an electric motor was to be attached to the main reduction gear to turn the drive shaft and propel the ship at speeds under , such as during BMD or maritime security operations. Use of the HED for half the time could extend time on station by 2.5 days before refueling. In March 2018, the Navy announced the HED would be installed on to test the technology, but upgrades of further destroyers would be halted due to changed budget priorities.

Also in 2016, four destroyers of the U.S. 6th Fleet based in Naval Station Rota, Spain (USS ''Carney'', USS ''Ross'', USS ''Donald Cook'', and USS ''Porter'') received self-protection upgrades, replacing one of their two Phalanx CIWS with a SeaRAM CIWS, which combines the Phalanx sensor dome with an 11-cell RIM-116 launcher. This was the first time the system was paired with an Aegis ship. Another four ships (USS ''Arleigh Burke'', USS ''Roosevelt'', USS ''Bulkeley'', and USS ''Paul Ignatius'') have since been forward-deployed to Rota and also received a SeaRAM.

In February 2018, Lockheed Martin received a contract to deliver its High Energy Laser with Integrated Optical-dazzler and Surveillance (HELIOS) system for installation onto an ''Arleigh Burke'' destroyer. HELIOS is a "60+ kW"-class laser, scalable to 120 kW, that can "dazzle" or destroy small boats and UAVs up to away. It would be the first laser weapon put on a warship. In November 2019, had the Optical Dazzling Interdictor, Navy (ODIN) system installed. ODIN differs from the XN-1 LaWS previously mounted on in that ODIN functions as a dazzler, which blinds or destroys optical sensors on drones rather than shooting down the aircraft. HELIOS was delivered to the Navy in August 2022 and installed on . ''Preble'' was expected to begin at-sea testing of the HELIOS in FY2023.

Also by 2018, all ''Arleigh Burke''-class ships homeported in the Western Pacific were scheduled to have upgraded ASW systems, including the TB-37U MFTA replacing the AN/SQR-19 TACTAS.

In FY2019, the Navy started a program to procure the Mod 4 variant of the Mark 38 machine gun system to address "unmanned aerial systems (UAS) and high speed maneuverable unmanned surface vehicle (USV) threats." Mod 4 will incorporate the 30 mm Mk44 Bushmaster II instead of the 25 mm M242 Bushmaster of previous variants. The Mk 38 Mod 4 is planned to be fielded on Flight IIA and III ''Arleigh Burke''-class destroyers.

In October 2020, National Security Advisor Robert C. O'Brien said that all three Flights of the ''Arleigh Burke''-class destroyer would field the Common-Hypersonic Glide Body (C-HGB) missile developed under the Conventional Prompt Strike program. However, the C-HGB is expected to be around wide, making it too large to fit in Mk 41 VLS tubes or on deck launchers. Installing them on ''Arleigh Burke'' destroyers would require removing some Mk 41 cells to accommodate the larger weapon, an expensive and time-consuming process. There is criticism of this idea: the oldest Flight I ships would need a service life extension to justify refit costs that would only prolong their service lives a short time when they are already more expensive to operate, and the newest Flight III ships that are optimized for BMD would be given a new, complex mission requiring a major refit shortly after introduction.

About 20 Flight IIA destroyers will undergo further modernization under the DDG MOD 2.0 program. DDG MOD 2.0 will backfit SPY-6(V)4 and Aegis Baseline 10 to provide similar capabilities to Flight III ships, as well as upgrade cooling systems to support the new radar. DDG MOD 2.0 will also deliver the AN/SLQ-32(V)7 EW suite, which adds the SEWIP Block 3 electronic attack subsystem. In May 2021, the Navy approved a "Smart Start Plan" for four ships—DDGs 91, 93, 95, 97—to make a gradual transition to DDG MOD 2.0. These ships will undergo a DDG MOD 1.5 phase that provides the SLQ-32(V)7; in 2023, DDG-91 became the first destroyer to receive SLQ-32(V)7. They will then receive the SPY-6(V)4, Aegis Baseline 10, and cooling system upgrades during a later depot modernization period.

Starting in 2025, the Navy will replace Phalanx CIWS on the destroyers with RIM-116 Rolling Airframe Missile (RAM) launchers to improve their point defense capability. ''Arleigh Burke''s with the latest Aegis baselines will receive the 21-cell Mk 49 RAM launcher; ''Arleigh Burke''s with older Aegis software will receive the 11-cell SeaRAM. It is unclear if ships with two Phalanx CIWS or ships already in a Phalanx-SeaRAM configuration will retain one Phalanx.

Production restarted

was originally intended to be the last of the ''Arleigh Burke'' class. The Navy planned to shift production to the ''Zumwalt''-class destroyer focusing on NGFS and littoral operations. However, at a July 2008 hearing, Navy officials announced intentions to restart ''Arleigh Burke'' production in place of additional ''Zumwalt''s, testifying to the latter's inability to counter emerging ballistic missiles, anti-ship missiles, and blue-water submarines. ''Arleigh Burke''-class destroyers have been in production for longer than any other surface combatant class in the U.S. Navy's history.

In April 2009, the Navy announced a plan limiting the ''Zumwalt'' class to three units while ordering another three ''Arleigh Burke''-class ships from both Bath Iron Works and Ingalls Shipbuilding. In December 2009, Northrop Grumman received a $170.7 million letter contract for long lead-time materials. Shipbuilding contracts for DDG-113 to DDG-115 were awarded in mid-2011 for $679.6 million–$783.6 million; these do not include government-furnished equipment such as weapons and sensors, which took the average cost of the FY2011/12 ships to about $1.843 billion per vessel.

DDGs 113 through 115 are "restart" ships, similar to previous Flight IIA ships, but including modernization features such as OACE and the TB-37U MFTA, which are being backfit onto previous ships.

The U.S. Navy was considering extending the acquisition of ''Arleigh Burke''-class destroyers into the 2040s, according to revised procurement tables sent to Congress, with the procurement of Flight IV ships from 2032 through 2041. This was canceled to cover the cost of the s, with the air defense commander role retained on one cruiser per carrier strike group.

In April 2022, the Navy proposed a procurement plan for nine ships, with an option for a tenth, to build two ships a year from 2023 to 2027. Some lawmakers pushed to add a third ship to be built in 2023, bringing the total of the proposed deal to eleven ships. This would follow the Navy's two-ship per year procurement from 2018 to 2022.

Flight IIA Technology Insertion

DDG-116 to DDG-124 and DDG-127 will be "Technology Insertion" ships with elements of Flight III. For example, and onwards have the AN/SPQ-9B, a feature of Flight III, instead of the AN/SPS-67. Flight III proper began with the third ship procured in 2016, (DDG-125).

Flight III (2013)

In place of the canceled CG(X) program, the U.S. Navy began detailed design work on a DDG-51 Flight III design in FY2013. The Navy planned to procure 24 Flight III ships from FY2016 to FY2031. In June 2013, it awarded $6.2 billion in destroyer contracts. Costs for the Flight III ships increased as requirements for the program grew, particularly related to the planned Air and Missile Defense Radar (AMDR) needed for the IAMD role. An AMDR with a mid-diameter of had been proposed for CG(X), while the DDG-51 Flight III design could carry an AMDR with a mid-diameter of only . The Government Accountability Office (GAO) found that the design would be "at best marginally effective" because of the "now-shrunken radar". The U.S. Navy disagreed with the GAO findings, stating that the DDG-51 hull was "absolutely" capable of fitting a large enough radar to meet requirements.

The Flight III's AN/SPY-6 AMDR with a mid-diameter of uses an active electronically scanned array with digital beamforming, compared to the previous passive electronically scanned array AN/SPY-1D with a mid-diameter of . According to the SPY-6's contractor Raytheon, the 37-RMA SPY-6(V)1 is 30 times more sensitive and capable of detecting objects "half the size at twice the distance" compared to the SPY-1D. The Flight III's SPY-6 is integrated with Aegis Baseline 10. The new radar also requires more power; the three-megawatt, 450 V AG9140 generators were upgraded to four-megawatt, 4,160 V AG9160 generators. Additionally, the air conditioning plants were upgraded to increase the ships' cooling capacity. The area near where the two rigid-hull inflatable boats (RHIBs) are stored was enclosed to accommodate additional crew, so the RHIBs are stacked. Other modifications include replacement of the Halon-based fire suppression system with a water mist system and strengthening of the hull to support the design's additional weight.

Flight III achieved IOC in 2024. a total of 24 Flight III ships have been ordered. The U.S. Navy may procure up to 42 Flight III ships for an overall total of 117 ships of the class.

Replacement

In April 2014, the U.S. Navy began the development of a new destroyer to replace the ''Arleigh Burke'' class called the "Future Surface Combatant". The new class is expected to enter service in the 2030s and initially serve alongside the Flight III ''Arleigh Burke''s. The destroyer class will incorporate emerging technologies like lasers, onboard power-generation systems, increased automation, and next-generation weapons, sensors, and electronics. They will use technologies from other platforms, such as the ''Zumwalt''-class destroyer, littoral combat ships, and the .

The Future Surface Combatant may place importance on the ''Zumwalt''-class destroyer's electric drive system that provides propulsion while generating 58 megawatts of electrical power, levels required to operate future directed energy weapons. Initial requirements for the Future Surface Combatant emphasize lethality and survivability. The ships must also be modular to allow for inexpensive upgrades of weaponry, electronics, computing, and sensors over time as threats evolve. The Future Surface Combatant has evolved into the Large Surface Combatant, which became the DDG(X). The Navy plans to procure the first DDG(X) in FY2032.

Operational history

The class saw its first combat action through Tomahawk Land Attack Missile (TLAM) strikes against Iraq. Over 3 and 4 September 1996, and launched thirteen and eight TLAMs, respectively, as part of Operation Desert Strike. In December 1998, ''Arleigh Burke''-class destroyers again performed TLAM strikes as part of Operation Desert Fox. Eleven ''Arleigh Burke''s supported carrier strike groups engaged in Operation Iraqi Freedom, which included TLAM launches against ground targets during the operation's opening stages in 2003.

In October 2011, the Navy announced that four ''Arleigh Burke''-class destroyers would be forward-deployed in Europe to support the NATO missile defense system. The ships, to be based at Naval Station Rota, Spain, were named in February 2012 as ''Ross'', ''Donald Cook'', ''Porter'', and ''Carney''. By reducing travel times to station, this forward deployment allows for six other destroyers to be shifted from the Atlantic in support of the Pivot to East Asia. Russia threatened to quit the New START treaty over this deployment, calling it a threat to their nuclear deterrent. In 2018, CNO Admiral John Richardson criticized the policy of keeping six highly mobile BMD platforms "in a little tiny box, defending land", a role that he believed could be performed equally well at less cost by shore-based systems.

In October 2016, the ''Arleigh Burke''-class destroyers ''Mason'' and ''Nitze'' were deployed to the coast of Yemen after a UAE auxiliary ship was struck in an attack for which Houthi rebels claimed responsibility. On 9 October, while in the Red Sea, ''Mason'' detected two anti-ship missiles headed toward herself and nearby USS ''Ponce'' fired from Houthi-controlled territory. ''Mason'' launched two SM-2s, one ESSM, and a Nulka decoy. One AShM was confirmed to have struck the water on its own, and it is unknown if the second missile was intercepted or hit the water on its own. On 12 October, in the Bab el-Mandeb strait, ''Mason'' again detected an inbound anti-ship missile, which was intercepted at a range of by an SM-2. On 13 October, ''Nitze'' conducted TLAM strikes destroying three Houthi radar sites used in the previous attacks. Back in the Red Sea, ''Mason'' experienced a third attack on 15 October with five AShMs. She fired SM-2s and decoys, destroying or neutralizing four missiles. ''Nitze'' neutralized the fifth missile with a radar decoy.

On 7 April 2017, the ''Arleigh Burke''-class destroyers ''Ross'' and ''Porter'' conducted a TLAM strike against Shayrat Airfield, Syria, in response to Syrian President Bashar al-Assad's chemical attack on his people three days prior. The ships fired a total of 59 Tomahawk missiles. On 14 April 2018, ''Laboon'' and ''Higgins'' conducted another TLAM strike against Syria. They fired seven and twenty-three TLAMs, respectively. The strike targeted chemical weapon sites as part of a continued effort against Assad's use of chemical warfare. The ''Arleigh Burke''-class destroyers ''Donald Cook'' and ''Winston S. Churchill'' took positions in the Mediterranean prior to the 2018 strike to mislead defending forces.

In October and November 2023, the ''Arleigh Burke''-class destroyers USS ''Carney'' and USS ''Thomas Hudner'', while deployed in the Red Sea, shot down numerous drones and missiles. On 19 October, ''Carney'' shot down at least three cruise missiles and eight drones that were potentially targeting Israel. On 15 and 22 November, ''Thomas Hudner'' shot down numerous drones launched by Houthi rebels from Yemen. On 27 November, ''Carney'' detected two ballistic missile launches from Houthi-controlled territory headed towards herself and nearby M/V ''Central Park''; they splashed ten nautical miles away. On 29 November, ''Carney'' intercepted another Houthi missile. On 30 December, USS ''Gravely'' shot down two anti-ship ballistic missiles fired from Houthi-controlled territory at herself and nearby container ship '' Maersk Hangzhou''. On 30 January 2024, a Houthi anti-ship cruise missile fired toward the Red Sea came within one mile of ''Gravely''; she used her Phalanx CIWS to shoot down the missile.

During the Iranian strikes on Israel on 13 April 2024, USS ''Arleigh Burke'' and USS ''Carney'' fired four to seven SM-3s, shooting down at least three Iranian ballistic missiles. This was the first time the SM-3 was employed in combat.

On 1 October 2024, USS ''Bulkeley'' and USS ''Cole'' fired 12 SM-3 and SM-6 missiles against Iranian ballistic missiles.

Accidents and major incidents

USS ''Cole'' bombing

was damaged on 12 October 2000 while docked in Aden, Yemen, by an attack in which a shaped charge of 200–300 kg in a boat was placed against the hull and detonated by suicide bombers, killing 17 crew members. The ship was repaired and returned to duty in 2001.

USS ''Porter'' and MV ''Otowasan'' collision

On 12 August 2012, USS ''Porter'' collided with the oil tanker MV ''Otowasan'' near the Strait of Hormuz; there were no injuries. The U.S. Navy removed ''Porter''s commanding officer from duty. Repairs took two months at a cost of $700,000.

USS ''Fitzgerald'' and MV ''ACX Crystal'' collision

On 17 June 2017, collided with the MV ''ACX Crystal'' cargo ship near Yokosuka, Japan. Seven sailors drowned. Following an investigation, the ship's commanding officer, executive officer, and Command Master Chief Petty Officer were relieved of their duties. In addition, close to a dozen sailors were given non-judicial punishment for losing situational awareness. Repairs were originally to be completed by the summer of 2019. Initial repairs however, were made by February 2020. After the subsequent sea trials, she was brought in for additional repairs. The ship departed for her home port in June 2020.

USS ''John S. McCain'' and ''Alnic MC'' collision

On 21 August 2017, USS ''John S. McCain'' collided with the container ship ''Alnic MC''. The collision injured 48 sailors and killed 10, whose bodies were all recovered by 27 August. The cause of the collision was determined to be poor communication between the two ships and the bridge crew lacking situational awareness. In the aftermath, the ship's top leadership, including the commanding officer, executive officer, and Command Master Chief Petty Officer, were removed from command. In addition, top leadership of the U.S. Seventh Fleet, including the commander, Vice Admiral Joseph Aucoin, were relieved of their duties due to a loss of confidence in their ability to command. Other commanders who were relieved included Rear Admiral Charles Williams, commander of Task Force 70, and Captain Jeffrey Bennett, commodore of Destroyer Squadron 15. This was the third incident involving a U.S. Navy ship in 2017, with a repair cost of over $100 million.
