The third tunnel was discovered in October 1978, which is only 12 km from Munsan and 52 km from Seoul. The 1,635 meters-long tunnel with 2 meters high and 2 meters wide is capable of moving a full division per hour.

It is evidently designed for an invasion of the south. North Korea insisted that it was designed for a surprise attack on the north by South Korea whea it was found out.
