Three U.S. Navy submarines have been cleared for duty after a Jacksonville company performed unauthorized repairs on them.
Navy officials took the USS Minnesota, USS North Dakota and USS John Warner out of service after it discovered the company NuFlow had modified parts used in the fast-attack subs’ propulsion systems.
In an emailed statement, Naval Sea Systems Command spokeswoman Colleen O’Rourke says the Navy will take action to ensure contractors install only equipment that meets the Navy’s quality standards.
