PCU 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 for Admiral Elmo Zumwalt.[6][7] Zumwalt has stealth capabilities, having a radar cross-section akin to a fishing boat despite her large size.[8]


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.[9] 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.[9] A highly decorated war veteran, Zumwalt reformed the U.S. Navy's personnel policies in an effort to improve enlisted life and ease racial tensions.[9] After he retired from a 32-year naval career, he launched an unsuccessful campaign for the United States Senate.[9]

The hull classification symbol for Zumwalt is DDG-1000, eschewing the guided missile destroyer sequence that goes up to DDG-118 (currently the last of the named Arleigh Burke-class destroyers), and continue in the previous "gun destroyer" sequence left off with the last of the Spruance-class, USS Hayler. With the production run of the Zumwalt-class limited to three units, plans are underway for a third "flight" of Arleigh-Burke-class destroyers.

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.[10]

A contract worth $1.4 billion was awarded to General Dynamics on 14 February 2008 for the construction of Zumwalt at Bath Iron Works in Bath, Maine.[11]

Full rate production officially began on 11 February 2009.[12]

As of July 2008, the construction timetable was for General Dynamics to deliver the ship in April 2013, with March 2015 as the target for Zumwalt to meet her initial operating capability.[13] However, by 2012, the planned completion and delivery of the vessel had slipped to the 2014 fiscal year.[14]

The first section of the ship was laid down on the slipway at Bath Iron Works on 17 November 2011.[14] By this point, fabrication of the ship was over 60% complete.[14] The naming ceremony was planned for 19 October 2013,[15] but was canceled due to the United States federal government shutdown of 2013.[16]

Despite rumors that the launch of Zumwalt would be delayed until early 2014, the vessel was launched from its shipyard in Bath, Maine on 29 October 2013.[17][18]

In January 2014, Zumwalt began to prepare for heavy weather trials. The trials will see how the ship and her instrumentation reacts to high winds, stormy seas, and adverse weather conditions. The ship's new wave-piercing tumblehome hull configuration is made to reduce her radar cross-section. Tests will involve lateral and vertical accelerations and pitch and roll. Later tests will include fuel on-loading, data center tests, propulsion events, X-band radar evaluations, and mission systems activation to finalize integration of electronics, currently 90 percent complete out of 6 million lines of code. These all culminate in builders trials and acceptance trials, with delivery for U.S. Navy tests in late 2014 with initial operating capability (IOC) to be reached by 2016.[19]
