USS John S. McCain begins at-sea testing following repairs

The US Navy Arleigh Burke-class guided-missile destroyer USS John S. McCain has completed undergoing necessary repairs and is underway to conduct comprehensive at-sea testing.

During the at-sea testing, the destroyer and its crew will perform a series of demonstrations to evaluate that the ship’s onboard systems meet or exceed navy performance specifications. Among the systems that will be tested are navigation, damage control, mechanical and electrical systems, combat systems, communications, and propulsion application.

John S. McCain, assigned to Destroyer Squadron FIFTEEN (DESRON 15) and forward-deployed to Yokosuka, Japan, has completed the in-port phase of training, and will continue basic phase at-sea training in the coming months to certify in every mission area that the ship is required to perform and prepare for return to operational tasking.

John S. McCain completed repairs and extensive, accelerated upgrades to sensors and weapons systems over the last two years following a collision with the commercial oil tanker Alnic MC off the coast of Singapore on August 21, 2017. Ten of the destroyer’s crew were killed while five others were injured in the incident.
