The DDG(X) or Next-Generation Guided-Missile Destroyer program of the United States Navy aims to develop a class of surface combatants to succeed 22 Flight II Ticonderoga-class cruisers and 28 Flight I/II Arleigh Burke-class destroyers. [2] [3] The program is the culmination of the Large Surface Combatant (LSC) initiative that followed the cancellation of CG(X) and curtailing of the procurement of the Zumwalt-class destroyers. The ships will become the principal large surface combatants of the U.S. Navy. Compared to their predecessors, they will incorporate more powerful sensors and have more room and weight margin for growth. [4] [5]

History

With the cancellation of the CG(X) in 2010, the U.S. Navy embarked on new studies and programs for the future of the air defense role fulfilled by the Ticonderoga-class cruisers. Because the cruisers were built on the Spruance-class destroyer hulls, they had limited upgrade potential due to space, weight, and power margins. [6] [7]

Meanwhile, the procurement of the Zumwalt-class destroyers was severely curtailed due to high costs and a renewed emphasis on air and missile defense for larger combatants. [8] Eventually, the Navy chose to upgrade the Ticonderogas and procure the Flight III Arleigh Burke-class destroyers with the enhanced AN/SPY-6 and improved combat systems to supplement the Ticonderogas for air and missile defense.

The Navy also launched studies into a Future Surface Combatant (FSC) to replace the Ticonderoga-class—which will reach the end of their service lives in the 2020s—as well as older flights of the Arleigh Burke class. [9] The FSC evolved into the Large Surface Combatant (LSC) program, which became the DDG(X). The DDG(X) program office was established in June 2021. [10] [11] In February 2022, Gibbs & Cox was contracted to provide design and engineering support. [12] The Navy is retaining the lead design role. [13]

Design

Hull

Various hull configurations are currently being tested at Naval Surface Warfare Center (NSWC) Carderock and NSWC Philadelphia. A concept presented at the 2022 Surface Warfare Symposium depicts an angular hull form with displacement of 13,290 long tons (13,500 t), a conventional bow and a superstructure reminiscent of the Zumwalt-class destroyer. Future vessels of the class may be lengthened with a payload module for additional capabilities. [4] [14]

The DDG(X) hull design will incorporate lessons and elements from both the Arleigh Burke and Zumwalt designs. The vessels will be able to accommodate larger missile launch systems, improved survivability, and space, weight, power, and cooling margins for future growth. As the ships will replace the Ticonderoga-class cruisers, they will have air defense command and control facilities and accommodations for an admiral's staff. [15]

Propulsion

The DDG(X) will use Integrated Power System (IPS), a modern integrated turboelectric drive as employed on the Zumwalt class. The vessels are expected to have 50% greater range, a 120% greater time on station, and a 25% reduction in fuel burn compared to current U.S. Navy destroyers. [4]

Sensors

The sensors will initially be enlarged variants of the AN/SPY-6 radar mounted on the Flight III Arleigh Burke-class destroyers. The hull is designed with provisions for upgraded sensors in the future, including larger radar arrays. [4]

Weapons

The Navy states that the baseline DDG(X) design, like the Flight III DDG-51 design, is to include 96 standard Vertical Launch System (VLS) cells, with an ability to incorporate 12 large missile launch cells in place of 32 of the 96 standard VLS cells. [16] The vessels will be initially fitted with 32-cell blocks of the Mark 41 Vertical Launching System, with the concept image of the hull showing at least 3 such blocks. Instead of the Mk 41 block, large-cell launchers for hypersonic missiles can also be accepted, where existing naval missiles like RIM-174 Standard ERAM and BGM-109 Tomahawk could be quad-packed into the larger canister, leveraging design improvements in the Mk 41 Single Cell Launcher and U.S. Army's Typhon missile launcher from the Mid-Range Capability (MRC) program. [17]

The concept image shows the vessel mounting a main 5-inch (127-mm)/62 cal Mark 45 Mod 4 gun. Upgraded versions of the class may incorporate directed energy weapons, with lasers ranging from 150 to 600 kW. [4]

<span class="mw-page-title-main">Guided-missile destroyer</span> Destroyer equipped with guided missiles

A guided-missile destroyer (DDG) is a destroyer whose primary armament is guided missiles so they can provide anti-aircraft warfare screening for the fleet. The NATO standard designation for these vessels is DDG, while destroyers which have a primary gun armament or a small number of anti-aircraft missiles sufficient only for point-defense are designated DD. Nations vary in their use of destroyer D designation in their hull pennant numbering, either prefixing or dropping it altogether.

<i>Spruance</i>-class destroyer Destroyer class of the US Navy

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 United States Navy during the 1970s and 1980s. It was named in honor of U.S. Navy Admiral Raymond A. Spruance, who successfully led major naval battles in the Asiatic-Pacific Theater during World War II such as the Battle of Midway and the Battle of the Philippine Sea.

<i>Ticonderoga</i>-class cruiser Class of guided missile cruisers

The Ticonderoga class of guided-missile cruisers is a class of warships of the United States Navy, first ordered and authorized in the 1978 fiscal year. It was originally planned as a class of destroyers. However, the increased combat capability offered by the Aegis Combat System and the passive phased array AN/SPY-1 radar, together with the capability of operating as a flagship, were used to justify the change of the classification from DDG to CG shortly before the keels were laid down for Ticonderoga and Yorktown.

<i>Virginia</i>-class cruiser Nuclear guided-missile cruiser class of the US Navy

The Virginia class were four nuclear-powered, guided-missile cruisers that served in the United States Navy until the mid-to-late 1990s. The double-ended cruisers were commissioned between 1976 and 1980. They were the final class of nuclear-powered cruisers completed and the last ships ordered as Destroyer Leaders under the pre-1975 classification system.

<i>Zumwalt</i>-class destroyer Stealth missile destroyer class of the US Navy

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. The class was designed with a primary role of naval gunfire support and secondary roles of surface warfare and anti-aircraft warfare. 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 (AGS), turrets with 920 round magazines, and unique Long Range Land Attack Projectile (LRLAP) ammunition. LRLAP procurement was canceled, rendering the guns unusable, so the Navy re-purposed the ships for surface warfare. Starting in 2023, the Navy will remove the AGS from the ships and replace them with hypersonic missiles.

<i>Kongō</i>-class destroyer Guided-missile destroyer class in the Japanese Maritime Self-Defense Forces

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.

<span class="mw-page-title-main">United States Navy 1975 ship reclassification</span>

The United States Navy reclassified many of its surface vessels in 1975, changing terminology and hull classification symbols for cruisers, frigates, and ocean escorts.

The names of commissioned ships of the United States Navy all start with USS, for United States Ship. Non-commissioned, primarily civilian-crewed vessels of the U.S. Navy under the Military Sealift Command have names that begin with USNS, standing for United States Naval Ship. A letter-based hull classification symbol is used to designate a vessel's type. The names of ships are selected by the Secretary of the Navy. The names are those of states, cities, towns, important persons, important locations, famous battles, fish, and ideals. Usually, different types of ships have names originated from different types of sources.

CG(X) US Navy cruiser research program

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.

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.

The system is computer controlled and uses four complementary antennas to provide 360-degree coverage. The system was first installed in 1973 on USS Norton Sound and entered active service in 1983 as the SPY-1A on USS Ticonderoga. The -1A was installed on ships up to CG-58, with the -1B upgrade first installed on USS Princeton in 1986. The upgraded -1B(V) was retrofitted to existing ships from CG-59 up to the last, USS Port Royal.

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 launching system (VLS) concept was derived from work on the Aegis Combat System.

Cruiser baseline

The cruiser baseline (CGBL) was a design study for a ship that has the combat capabilities of VLS-capable Ticonderoga-class cruiser while designing the hull to DDG-51 standards and technology. The resulting design was considerably larger than the Ticonderoga-class design, owing to increased margins and allowances for weight and mission growth.
