Oh, those crafty North Koreans—the Dong-A Ilbo, quoting military sources, reports that North Korea has deployed long-range 170mm self-propelled artillery and 240mm multiple rocket launchers to inland distracts of Jangyon and Yongyon counties, just across from Baengyeongdo and just outside of South Korean artillery range.
The 170mm guns and 240mm MRLs are usually attached to the KPA 4th Corps and based in Kangnyong, Yeonan and Chongdan, where they are tasked with hitting the Seoul and Incheon areas in the event of an emergency.
The ranges on those guns are 24—54km and 40—65km, respectively. The range for South Korea’s K-9 guns on Baengnyeongdo is 40km, while the Guryong MRLs have a range of 36km. This means if North Korea hits Baengnyeongdo with its long-range guns, Baengnyeongdo’s defenders will be unable to hit them back.
Anyway, the South Korean military does not view North Korea’s deployment of long-range guns near Baengnyeongdo to be a good sign. The ranges on those guns are much longer than the ones used to hit Yeonpyeongdo in 2010. The fact that Kim Jong-un has recently made several visits to West Sea artillery units supports analysis that North Korea may launch a provocation at Baengnyeongdo.
