The US Navy’s high tech aircraft carrier, USS Gerald R. Ford (CVN-78) suffered a propulsion system failure that forced it to return to port for repairs.

It was the second failure in less than a year with a “main thrust bearing” that’s part of the $12.9 billion carrier’s propulsion system. The first occurred in April 2017, during sea trials a month before the vessel’s delivery. The ship, built by Huntington Ingalls Industries Inc., has been sailing in a shakedown period to test systems and work out bugs. It’s now scheduled to be ready for initial combat duty in 2022.

The Naval Sea Systems Command said the Ford experienced “an out of specification condition” with a propulsion system component. Huntington Ingalls determined it was due to a “manufacturing defect,” the command said, and “not improper operation” by sailors. – Bloomberg
