USS Zumwalt (DDG-1000) is a guided missile destroyer of the United States Navy. She is the lead ship of the Zumwalt class and the first ship to be named after Admiral Elmo Zumwalt. [10] [11] Zumwalt has stealth capabilities, having a radar cross-section similar to a fishing boat despite her large size. [12] On 7 December 2015, Zumwalt began her sea trial preparatory to joining the Pacific Fleet. [13] The ship was commissioned in Baltimore on 15 October 2016. [4] Her home port is San Diego, California. [14]

Admiral Elmo Zumwalt Elmo Zumwalt.jpg
Admiral Elmo Zumwalt

Zumwalt is named after Elmo Russell Zumwalt Jr., who was an American naval officer and the youngest man to serve as the Chief of Naval Operations. [15] As an admiral and later the 19th Chief of Naval Operations, Zumwalt played a major role in U.S. military history, especially during the Vietnam War. [15] A highly decorated war veteran, Zumwalt reformed the US Navy's personnel policies in an effort to improve enlisted life and ease racial tensions. [15] After he retired from a 32-year naval career, he launched an unsuccessful campaign for the United States Senate. [15]

The hull classification symbol for Zumwalt is DDG-1000, which departs from the guided missile destroyer numbering sequence that goes up to DDG-139, which as of 2022, is Telesforo Trinidad, the latest of the named Arleigh Burke-class destroyers. Zumwalt continues the previous "gun destroyer" sequence left off with 1983, DD-997, the last of the Spruance class, Hayler.

Role

The Zumwalt class was designed with multimission capability. Unlike previous destroyer classes, designed primarily for deep-water combat, the Zumwalt class was primarily designed to support ground forces in land attacks, in addition to the usual destroyer missions of anti-air, anti-surface, and antisubmarine warfare.

Zumwalt was initially equipped with two Advanced Gun Systems (AGS), which were designed to fire the Long Range Land Attack Projectile (LRLAP). LRLAP was to be one of a range of land attack and ballistic projectiles for the AGS, but was the only munition the AGS could use. LRLAP had a range of up to 100 nautical miles (190 km; 120 mi) fired from the AGS. It was to be a key component for ground forces support, [16] [ unreliable source? ] but LRLAP procurement was cancelled in 2016 [17] [18] and the Navy has no plan to replace it. [9] Since Zumwalt class cannot provide naval gunfire support the Navy has re-purposed the class to surface warfare. [19] During a refit starting in 2023, the AGS systems are being replaced by missiles. [20]

History

Construction

Many of the ship's features were originally developed under the DD21 program ("21st Century Destroyer"). In 2001, Congress cut the DD-21 program by half as part of the SC21 program. To save it, the acquisition program was renamed as DD(X) and heavily reworked. The initial funding allocation for DDG-1000 was included in the National Defense Authorization Act of 2007. [21] By February 2008, a $1.4 billion contract had been awarded to Bath Iron Works in Bath, Maine, [22] and full rate production officially began a year later, on 11 February 2009. [23]

In July 2008, a construction timetable was set for General Dynamics to deliver the ship in April 2013, with a March 2015 target date for Zumwalt to meet her initial operating capability [24] but, by 2012 the planned completion and delivery of the vessel was delayed to the 2014 fiscal year. [25] The first section of the ship was laid down on the slipway at Bath Iron Works on 17 November 2011, [25] by which point, fabrication of the ship was over 60% complete. [25] The naming ceremony was planned for 19 October 2013, [26] but was canceled due to the United States federal government shutdown of 2013. [27] The vessel was launched on 29 October 2013. [28] [29]

Sea trials

In January 2014, Zumwalt began to prepare for heavy weather trials, to see how the ship and her instrumentation react to high winds, stormy seas, and adverse weather conditions. The ship's new wave-piercing inverted bow and tumblehome hull configuration reduced her radar cross-section. Tests involved lateral and vertical accelerations and pitch and roll. Later tests included fuel on-loading, data center tests, propulsion events, X-band radar evaluations, and mission systems activation to finalize integration of electronics. These all culminated in builders' trials and acceptance trials, with delivery for US Navy tests in late 2014, and with initial operating capability (IOC) to be reached by 2016. [30]

Zumwalt's first commanding officer was Captain James A. Kirk. [31] Kirk attracted some media attention when he was first named the captain, due to the similarity of his name to that of the Star Trek television character Captain James T. Kirk, played by William Shatner. Shatner wrote a letter of support to Zumwalt's crew in April 2014. [32] On 7 December 2015, the ship departed Bath Iron Works for sea trials to allow the Navy and contractors to operate the vessel under rigorous conditions to determine whether Zumwalt was ready to join the fleet as an actively commissioned warship. [13]

On 12 December 2015, during sea trials, Zumwalt responded to a US Coast Guard call for assistance for a fishing boat captain who was experiencing a medical emergency 40 nautical miles (74 km) from Portland, Maine. Due to deck conditions, the Coast Guard helicopter was unable to hoist the patient from the fishing boat, so Zumwalt's crew used their 11-meter rigid-hulled inflatable boat (RHIB) to transfer him to the destroyer, from which he was transported to shore by the Coast Guard helicopter and then to a hospital. [33] The US Navy accepted initial delivery of Zumwalt on 20 May 2016. [34] In September 2016, it was reported that the vessel needed repairs after the detection of a seawater leak in the ship's auxiliary motor drive oil system. [35] The US Navy commissioned Zumwalt on 15 October 2016, in Baltimore during Fleet Week. [4]

Post-commissioning

On 21 November 2016, Zumwalt lost propulsion in her port shaft while passing through the Panama Canal from the Atlantic to the Pacific Ocean en route to her homeport in San Diego. [36] Water had intruded in two of the four bearings that connect Zumwalt's port and starboard Advanced Induction Motors to the drive shafts. [36] Both drive shafts failed and Zumwalt struck the lock walls in the canal, causing minor cosmetic damage. [36] Zumwalt's passage through the Panama Canal had to be completed with tugboats. [36] Zumwalt underwent repairs at Vasco Núñez de Balboa Naval Base near the Pacific end of the canal before continuing on to Naval Station San Diego. [36] [37] Upon the ship's arrival in San Diego, the leak was revealed to be through the lubrication cooling system, though the cause remains unknown. Sources close to the incident described the completion of the canal transit with tugboats a prudent measure, and lauded Captain Kirk for quick thinking and integrity to acknowledge the cooling system failure rather than risk damage to the propulsion system by steering the ship to the dock without assistance. [38]

Post-delivery

In April 2019, Zumwalt departed San Diego for a first operational deployment into the Pacific since the shipyard availability conducted in 2017 and 2018. [39] This patrol included a visit to Ketchikan, Alaska, [40] during which Zumwalt's watch teams were able to conduct stability trials in stormy seas (Sea State 6), [41] and Pearl Harbor, marking the first visit of a Zumwalt Class Destroyer to Hawaii. [42] The Navy accepted final delivery in April 2020, preparing for more sea tests. [43]

In September 2022 Zumwalt made her first port call in Guam during the longest voyage since the ship was commissioned enroute to Japan. [44]

On August 1, 2023, Zumwalt got underway to her new homeport in Ingalls Shipbuilding in Pascagoula, Mississippi for a modernization period and to receive technology upgrades. [20]

<i>Arleigh Burke</i>-class destroyer US Navy guided-missile destroyer class

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 for Admiral Arleigh Burke, an American destroyer officer in World War II and later Chief of Naval Operations. With an overall length of 505 to 509.5 feet, 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.

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>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.

A destroyer squadron is a naval squadron or flotilla usually consisting of destroyers rather than other types of vessel. In some navies other vessels, such as frigates, may be included. In English the word "squadron" tends to be used for larger and "flotilla" for smaller vessels; both may be used for destroyer units. Similar formations are used in non-English-speaking countries, e.g., the "escadrille"—which would translate directly as "squadron"—in France.

<span class="mw-page-title-main">Advanced Gun System</span> Naval artillery

The Advanced Gun System (AGS) is a naval artillery system developed and produced by BAE Systems Armaments & Services for the Zumwalt-class destroyer of the United States Navy. Designated the 155 mm/62 (6.1-inch) Mark 51 Advanced Gun System (AGS), it was designed to provide long-range naval gunfire support against shore-based targets. A total of six of the systems were installed, two on each of the three Zumwalt-class ships. The Navy has no plans for additional Zumwalt-class ships, and no plans to deploy AGS on any other ship. AGS can only use ammunition designed specifically for the system. Only one ammunition type was designed, and the Navy halted its procurement in November 2016 due to cost, so the AGS has no ammunition and cannot be used. The Navy planned to remove the AGS from the ships starting in 2023.
