The US Navy’s second Zumwalt-class guided missile destroyer, the future USS Michael Monsoor (DDG-1001), has reportedly suffered from electrical system issues during its builder’s trials.
A US Naval Sea Systems Command (NAVSEA) statement, which was cited by USNI News, said the destroyer has now returned to General Dynamics subsidiary Bath Iron Works’ shipyard in Maine.
The news was first reported by the Associated Press.
The vessel’s harmonic filter failed during the trials, restraining the electric system from operating at full power, NAVSEA said.
USS Michael Monsoor initially commenced sea trials from the shipyard on 4 December.
NAVSEA was reported to have further noted that the electrical system issue and delay in the trials would not affect the vessel’s expected delivery, which is currently slated for March next year.
USS Zumwalt, the lead ship in the class, had also experienced issues regarding its complicated integrated power system (IPS).
The same IPS is currently being deployed on all three of the US Navy’s Zumwalt-class ships.
The 610ft-long Zumwalt multi-mission surface combatants have a displacement capacity of more than 15,000t when fully loaded and can carry a maximum crew of 142 each.
In addition, the vessels use electricity generated by gas turbines to power all of its systems, including their weapons.
The ships have been designed for littoral operations and land attack missions, and are fitted with various new technologies such as the Advanced Gun System from BAE Systems.
