Japan releases audio file in ‘final statement’ on radar lock-on dispute with South Korea

21 January 2019

The Japanese Ministry of Defense (MoD) has released an 18 second audio file containing what Tokyo claims is the sound – converted from radio waves – recorded when a Republic of Korea Navy (RoKN) destroyer locked its fire-control radar onto a Japanese Maritime Self-Defense Force (JMSDF) Kawasaki P-1 maritime patrol aircraft (MPA) as it flew over the Sea of Japan (also known as East Sea) on 20 December 2018.

In what it referred to as its “final statement” on the incident, the MoD said on 21 January that the radio waves directed at the P-1 showed “characteristics unique to that of fire-control radars”, thus “confirming” that the MPA “was continuously irradiated for a certain period, multiple times by the fire-control radar (STIR 180)” fitted onto RoKN KDX-I-class destroyer Gwang Gae To Daewang (pennant number 971).
