Improper radar operation cited in USS Champlain collision

04 December 2017

The 9 May collision between USS Champlain (CG 57) and South Korean fishing vessel Nam Yang 502 might have been avoided if the bridge watch team aboard the US Navy (USN) guided-missile cruiser had maintained a proper radar track, according to a USN memorandum on the mishap.

“Watch team members were not familiar with basic radar fundamentals, impeding effective use,” the 29 November memorandum said. “ Lake Champlain did not hold radar track on Nam Yang 502 for sixteen minutes leading up to the collision, and it is possible that proper radar tuning would have prevented this problem.”

Lake Champlain was deployed to the Western Pacific, conducting patrols within the Sea of Japan and routinely operating within the vicinity of fishing vessels.
