BAE Systems Awarded 90 Million Contract to Maintenance Zumwalt-class DDG 1000 and DDG 1001

BAE Systems San Diego Ship Repair, San Diego, California, is awarded a $90,000,000 modification to increase the ordering ceiling to previously awarded indefinite-delivery/indefinite quantity contract for yard work, maintenance and modernization efforts including, but not limited to, post-delivery, post-shakedown, combat system and continuous maintenance availabilities for DDG 1000 and DDG 1001. Work will be performed in San Diego, California, and is expected to complete September 2023. This modification increases the contract ceiling from $192,682,485 to $282,682,485. Orders may be issued on a cost-plus-award-fee or firm-fixed-price basis.The Naval Sea Systems Command, Washington, D.C., is the contracting activity.

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. Zumwalt has stealth capabilities, having a radar cross-section similar to a fishing boat despite her large size. On 7 December 2015, Zumwalt began her sea trial preparatory to joining the Pacific Fleet. The ship was commissioned in Baltimore on 15 October 2016.USS Michael Monsoor (DDG-1001) is the second ship of the three-ship Zumwalt class of guided missile destroyers. The Zumwalt-class was designed as a multi-mission surface combatant for land attack and littoral operations with a mission of supporting both ground campaigns and the joint/naval battlespace.

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. It is a multi-role class that was designed for secondary roles of surface warfare and anti-aircraft warfare and originally designed with a primary role of naval gunfire support. The class design emerged from the DD-21 “land attack destroyer” program as “DD(X)”. The ship is designed around its two Advanced Gun Systems, their turrets and magazines, and unique Long Range Land Attack Projectile (LRLAP) ammunition. LRLAP procurement was cancelled, rendering the guns unusable, so the Navy re-purposed the ships for surface warfare.

These ships are classed as destroyers, but they are much larger than any other active destroyer or cruiser in the US Navy. The vessels’ distinctive appearance results from the design requirement for a low radar cross-section (RCS). The Zumwalt class has a wave-piercing tumblehome hull form whose sides slope inward above the waterline, which dramatically reduces RCS by returning much less energy than a conventional flare hull form. The class has an integrated electric propulsion (IEP) system that can send electricity from its turbo-generators to the electric drive motors or weapons, the Total Ship Computing Environment Infrastructure (TSCEI),[17] automated fire-fighting systems, and automated piping rupture isolation.
