South Korea resumes operations on AW159 naval helicopters

13 January 2020

The Republic of Korea Navy (RoKN) has resumed operations on seven of its eight AW159 naval helicopters.

The entire fleet of anti-submarine warfare (ASW)-capable aircraft was grounded in November 2019 as a precautionary measure after abnormal vibrations were detected in one of the helicopters during a routine patrol operation, said a RoKN representative in an email reply to Jane’s on 11 January.
