Repairs have been completed on the guided-missile destroyer USS John S. McCain, which was involved in a collision in 2017 that left 10 sailors dead and caused hundreds of millions of dollars in damages, and the vessel is now conducting ¡°comprehensive at-sea testing,¡± the U.S. Navy said Monday.

In its first sea voyage since the deadly accident, the Yokosuka, Kanagawa Prefecture-based ship and its crew were due to perform a series of demonstrations to evaluate whether its onboard systems meet the U.S. Navy¡¯s minimum performance specifications.

Among the systems that will be tested are navigation, damage control, mechanical and electrical systems, as well as combat systems, communications and propulsion applications.
