The second tunnel was discovered on march 19, 1975, in the middle front line portion of the DMZ, north of Chorwon. It was Discovered just 4 months after Tunnel 1 was discovered , however , everyone was shocked that this tunnel was twice as big as the first tunnel. Tunnel 2, which is located 13km north of Chorwon, is approximately 50-160m underground and runs through the granite bedrock layer, compressors and explosive charges were used in creating this tunnel which was constructed in an arch-like shape.

Located along the tunnel route are open gathering areas where the soldiers and workers would be brought together this made Tunnel 2 the largest tunnel in the world at that time. Tunnel 2 also was built with 3 exits. Tunnel 2 is 2,496m long, 2m high and 2m wide and could accommodate up to 30,000 troops with cars, field artillery, and tanks every hour.

This would allow North Korea to carry on both conventional warfare and underground-based guerilla warfare at the same time.

Tunnel 2’s location is a tactical point at the beginning of the invasion route running through Pochon to Seoul, similar to the route used in the Korean War. After the discovery of Tunnel 2 North Korea insisted it was a natural cave and had even used coal markings to camouflage the walls of the tunnel to appear natural, but this story was proven wrong by the disclosure of evidence by Kim, Bu-sung, a North Korean defector who had worked in the tunnel as a surveyor in January of 1972 and as a compressor operator in September of 1972.

Even without his evidence there are many other things to prove the tunnel was constructed by North Korea, such as the downward slope towards South Korea to help the flow of water and explosive charges used to break up the rock. Kim, Bu-sung was also first to indicate that another tunnel of the same size as Tunnel 2  was being built. The northern entrance to the tunnel is located approximately 5-6m behind a North Korean Guard Post within the northern section of the DMZ. Kim also believed that 5 exits on the south side of the DMZ were constructed with 1-2 of the exits to be used during normal times and all being used in the case of an emergency. He also disclosed that many other tunnels were being built along the 155 mile long DMZ. During the discover 7 South Korean soldiers were killde by North Korean booby traps.
