The DDG-1000 Zumwalt Class Destroyer

About the Zumwalt Destroyer:





Developed under the DD(X) destroyer program, the DDG 1000 Zumwalt Class destroyer is a class of next-generation multi-mission combat ships designed for land attack and littoral (close-to-shore) dominance. The ships are built by General Dynamics-Bath Iron Works (design, construction, integration, testing and delivery) and Huntington Ingalls Industries (deckhouse, helo hangar and aft Peripheral Vertical Launch System). Key subcontractors are Raytheon (software development and integration), BAE Systems (Advanced Gun System and Long Range Land Attack Projectiles), and Rolls-Royce (marine gas turbine engines).

In July 2008, the U.S. Navy announced its decision to limit the number of ships to be delivered under the DDG 1000 program to just three (32 ships were originally planned) - and restart the construction of Ballistic Missile Defense (BMD) capable DDG 51 Arleigh Burke Class AEGIS Destroyers.

The Zumwalt Class ships is powered by two Rolls-Royce MT30 twin-spool, high-pressure ratio, marine gas turbine engines and two RR4500 Auxiliary Turbine Generator Sets (ATGs) for a total of more than 78 MW ship power. The MT30s and ATGs each provide 35.4 MW and 3.8 MW, respectively.

Armed with an array of weapons, DDG 1000 will provide offensive, distributed and precision firepower at long ranges in support of forces on land. To ensure effective performance in littoral operations, the Zumwalt destroyer incorporates full-spectrum radar signature reduction, active and passive self-defense systems, and cutting-edge survivability features. The U.S. Navy has incorporated technologies developed under the DDG 1000 program into new surface combatants such as the Littoral Combat Ship (LCS). Compared to DDG 51 AEGIS Destroyers, the DDG 1000 will triple naval surface fire coverage and significantly boost the anti-ship cruise missile capability.

DDG 1000 is a stealthy ship with a minimal radar signature (50-fold radar cross section reduction) and an intrinsically quiet tumblehome hull form and wave-piercing bow. The angular deckhouse is constructed of rugged, lightweight composites and its surfaces incorporate all radar apertures and communication antennas, thus eliminating high-profile masts and rotating antennas.

The DDG 1000 is equipped with the Raytheon Dual Band Radar (DBR) system, which combines the functionality of the AN/SPY-3 X-band Multifunction Radar and the S-band Volume Surveillance Radar (VSR) to provide an unprecedented level of detection and tracking capability. The AN/SPY-3 is the first U.S. shipboard Active Electronically Scanned Array (AESA) radar system. The Zumwalt Class ships generate more power than DDG 51 ships, which makes DDG 1000 suitable for future deployment of directed energy beam weapons and the electromagnetic railgun.

Production of the USS Zumwalt (DDG 1000), the first of the class, began at Bath Iron Works (BIW) on February 11, 2009. The ship was christened at BIW's shipyeard in Bath, ME on April 12, 2014; delivered to the Navy on May 20, 2016; and commissioned in Baltimore, MD on October 15, 2016. The second ship of the class, Michael Monsoor (DDG 1001), was christened on June 18, 2016. The keel was laid for the Lyndon B. Johnson (DDG 1002) on January 30, 2017.



Armament/Ship Self-Defense:

The DDG 1000 is equipped with two BAE Systems 155mm Advanced Gun Systems (AGS) that can pinpoint land targets with GPS precision. The AGS fires the Long-Range Land Attack Projectile (LRLAP), which has an effective range of up to 63 nautical miles, thus tripling fire-support coverage compared to the Mk 45 5-inch (127mm) gun employed by the DDG 51. The AGS holds up to 600 rounds in two magazines and will be capable of a maximum sustained firing rate of 10 rounds per minute. With the AGS, each DDG 1000 can mass 140 to 160 projectiles in the air at once. Also, the DDG 1000 is equipped with two General Dynamics Mk 46 30mm naval gun systems that have range of 2.2 nautical miles and fire at a rate of 200 rounds per minute (originally two BAE Systems Mk 110 57mm close-in gun systems (CIGS) were planned). The Zumwalt class is also quipped with a total of 80 Mk 57 peripheral Vertical Launching System (VLS) cells for RIM-162 Evolved Sea Sparrow Missiles (ESSM), RUM-139 VL-ASROC missiles, and RGM-109E Tactical Tomahawk cruise missiles.



Mission/Role:

DDG 1000 will provide independent forward presence and deterrence as well as an advanced land-attack capability in support of ground campaigns. The Zumwalt Destroyer will contribute to naval, joint or combined battle space dominance in littoral operations. The DDG 1000 will establish and maintain surface and sub-surface superiority and provide local air defense.
