The third and final Zumwalt-class destroyer pulled away from the pier at General Dynamic Bath Iron Works in Maine on Wednesday.

Lyndon B. Johnson (DDG-1002) has left the shipyard and is in the Atlantic after traveling the Kennebec River after completing the first of a two-part delivery program for the Zumwalt class.

“Last November, the Navy officially accepted the completion of BIW production and test activity for the DDG 1002,” according to a statement from the shipyard.
“The Navy’s acceptance of Hull, Mechanical and Electrical (HM&E) completion followed extensive testing, trials and demonstrations of the ship’s systems both at the dock and during sea ​​trials last summer.”

Johnson is now bound for Ingalls Shipbuilding in Pascagoula, Mississippi, for combat system activation which will finalize the delivery of the ship’s radar and weapons systems.

The other ships of the class – USS Zumwalt (DDG-1000) and USS Michael Monsoor (DDG-1001) – transited from Maine to San Diego, CA to complete combat system activation.

The service will refrain from accepting the delivery of Johnson until the battle system is fully installed and tested.

“The program manager said this new approach could lead to further schedule delays; however, it will free up valuable space on the Naval Base San Diego pier and allow the Navy to avoid moving the crew aboard DDG-1002 until it is ready for operation,” reads -on in a June Government Accountability Office report.
“The program manager identified the change as a response to lessons learned from the DDG-1000 and 1001, in particular that combat system activation and final construction are complicated by the crew on board, in part because the access to spaces is more restricted.”

Delivery of the ship to service is expected in 2024, USNI News reported.

The Zumwalt class will be the first Navy platform to deploy hypersonic weapons by replacing one or both of the advanced 155mm gun system with larger airframes to accommodate the missiles by 2025, previously reported USNI News. It is unknown which Zumwalt will use the weapons first.

For Bath, the departure of Johnson will free up space in the Maine yard for manpower to focus on the remaining Arleigh Burke DDG-51 guided missile destroyers under construction.
The three 16,000-ton vessels have stretched the shipyard’s capacity and caused delays in ship deliveries in recent years.

“Bath Iron Works currently has the Arleigh Burke-class destroyers under construction Carl M. Levin (DDG-120), Jean Basilone (DDG 122), Harvey C. Barnum Jr.. (DDG-124) and Patrick Gallagher (DDG-127) as well as Flight III configuration destroyers Louis H. Wilson Jr. (DDG-126), Guillaume Charette (DDG-130) and Quentin Walch (DDG-132)”, according to the yard.
