Chosun TV [2] is reporting that South Korean military have lost contact with two North Korean submarines that left their naval base in Hwanghae Province a few days ago.
There has obviously been a lot of changes between last week and now and South Korean military officials suggested that while maneuvers in February were nothing meaningful, now it is provocation.
The two 'torpedo' subs are small 130-ton, 30-meter, 10-man machines that can stay submerged for three-to-four days.
