Navy’s newest destroyer “Zumwalt” broken down in Panama Canal
The Navy's newest destroyer, USS Zumwalt (DDG 1000), broke down while transiting the Panama Canal and is now pierside at the former Rodman Naval Station awaiting repairs. The destroyer suffered what USNI News reports as "minor cosmetic damage" as a result of the engineering failure.
According to the USNI News report, the destroyer's engineering casualty was caused by water induction in bearing for the ship's Advanced Induction Motors, which are driven by the ship's gas turbines, and which generate the electric power to turn the two shafts on the vessel. The Advanced Induction Motors also provide electrical power for the ship's systems.
The water induction caused both shafts to stop, and the Zumwalt had to receive assistance from tugboats to complete its transit of the canal. The vessel had mechanical problems in September, prior to its commissioning on Oct. 15 of this year. In both the September incident and this one, the apparent cause seems to be leaks in the ship's lube oil coolers. The destroyer also took a hit when the Long-Range Land Attack Projectile for its Advanced Gun Systems was cancelled due to rising costs.
The Zumwalt is not the only vessel to have had engineering problems. Since late 2015, at least five Littoral Combat Ships have also had engineering issues, and the Navy's new aircraft carrier, USS Gerald R. Ford (CVN 78), has had trouble with its flight systems, including the Electromagnetic Aircraft Launch System (EMALS), Advanced Arresting Gear (AAG), the weapons elevators and the ship's radar systems, including the AN/SPY-3 radar.
USS Zumwalt is slated to remain in Panama for ten days while the repairs are affected. It will then head to San Diego, where it will spend most of next year spinning up its weapon systems. In addition to the Advanced Gun Systems, the destroyer also has two Mk 44 30mm Bushmaster chain guns, and twenty four-cell Mk 57 vertical-launch systems (VLS). The ship can also carry two MH-60 helicopters.
Two sister ships to USS Zumwalt, USS Michael Monsoor (DDG 1001) and USS Lyndon B. Johnson (DDG 1002), are under construction. The class was originally planned to consist of 32 ships.
