How North Korea's James Bond Super Weapon Almost Started World War III

In 1998, South Korean president Kim Dae-jung came to power with a “Sunshine Policy” attempting to reconcile with North Korea. That policy included providing badly needed economic aid to relieve its northern neighbor as it recovered from a devastating famine. However, on the eve of a key peace conference in Panmunjom, a North Korean submarine on a spying mission got entangled in fishing nets and its crew committed suicide when South Korean ships began towing it back to port. Surely, given the overture and assistance provided by President Kim, the regime in Pyongyang would tamp down on its armed infiltration missions on South Korean soil?

But the North Korean government has always operated by its own unique internal logic, and just six months later, its political insecurities would lead to the deaths of several men in a flash of cannon fire off the southern coast of Korea—exposing another curious tale of espionage and subversion.

North Korea had lost two submarines in September 1996 and June 1998 while attempting to insert or exfiltrate Special Forces agents on espionage missions in South Korea, both incidents ending in tragedy. If there had been any hope that the embarrassment provoked these incidents would bring an end to the submarine missions, it should have been tempered by the discovery on July 13 of the body of a North Korean diver washed up on the beach at Donghae, South Korea. Apparently having suffered a heart attack, the diver was packing a Czech submachine gun, an underwater camera and a radio transmitter. An aluminum submersible vehicle was found nearby.

Then in November, South Korean patrol boats spotted a mini-submarine off the coast of Ganghwa Island, on the northwestern border between North and South Korea. The submarine withdrew when South Korean ships attempted to intercept it.

But whereas these earlier incidents occurred relatively close to the demilitarized zone separating the two Koreas, 1998 would end with an exchange of fire off the Yeosu peninsula, at the southern end of South Korea. At 11:15 the evening of December 16, a guard post spotted with infrared cameras a low-riding vessel with an “antenna” gliding through the water. Five minutes later, two ROK Navy patrol boats were dispatched to the area while harbor traffic was brought to a standstill. But the patrol boats could not locate the stealthy vessel.

Abruptly, at 1:40 a.m., radar detected a ship zooming at around fifty miles per hour only five miles away from shore. As many as a dozen South Korean vessels moved in pursuit of the contact, soon joined by three navy P-3 Orion maritime patrol planes. Finally, at 4:38 a.m., the Pohang-class antisubmarine corvette Gwangmyeong identified the vessel as a North Korean I-SILC semisubmersible.

The ten-ton Improved Submersible Infiltration Landing Craft looks like it belongs in a James Bond movie. Basically a nearly thirteen-meter-long low-riding motorboat coated in antiradar paint, it can submerging three meters deep while under power, exposing just the crew cab and a folding snorkel mast (likely the “antenna” observed by the guard post). Unlike an earlier predecessor captured in the 1980s, however, the I-SILC can fully submerge twenty to twenty-five meters deep to avoid detection, but lacks an electric motor to swim underwater. Though later types can fire lightweight 324-millimeter torpedoes, the boat intercepted off Yeosu had no other weaponry other than the small arms carried by the crew.

One of the orbiting P-3 patrol planes dropped flares in the vicinity of the boat, allowing four pursuing South Korean corvettes to close in upon it. As the spy craft fled south, approaching Japanese waters, the South Korean Navy notified the Japanese Self-Defense Force, which mobilized its own patrol vessels to observe the chase.

An hour later, the boat slowed down when it was roughly sixty miles south of Geoje Island. Perhaps it was running out of fuel, as it is estimated to have a range of 230 miles, implying it required pickup by a mother craft.

One of the South Korean corvettes fired warning shots off the semisubmersible’s bow. The infiltrators on board opened fire with a machinegun at their pursuers. One of the 1,300-ton corvettes then raked the motor boat with its forty-millimeter antiaircraft guns and blasted a chunk out of its port side with a seventy-six-millimeter rapid-fire cannon, causing the ruptured submersible to sink in waters three hundred feet deep. You can see the damage inflicted on the small craft in this photo.

The body of a single diver in a wetsuit was recovered at sea. South Korea issued a red alert order and searched for possible infiltrators deposited on its soil, as had occurred in the Gangneung incident. The Defense Minister demanded Pyongyang apologize, but North Korea denied any involvement. The typically caustic North Korean Central News Agency said, “Now the South Korean are trying hard to find a pretext for unleashing a war against the north in line with the U.S. imperialists’ moves for war against the DPRK. It goes without saying that the “north’s submarine infiltration incident” is a farce cooked up for that purpose. . . . We will take resolute measures so that the provokers may drink a bitter cup. We seriously warn the South Koreans not to act rashly.”
