Ballistic Force. Don Pendleton

of mountain tunnels had served as one of North Korea’s primary mining centers, yielding untold tons of coal, iron ore and magnesite. Most of the mine shafts had been long played out, but chain gangs made up of prisoners capable of more strenuous work than the poppy fields offered were sent daily into the mountain bowels with shovels and pickaxes to seek out new veins or to fill their carts with chiseled leavings.

      Once Oh’s jeep had passed through the security checkpoint at the main entrance, the general rode past the crude barracks and the work yard where inmates sifted through the latest haul from the mines. Beyond the yard there were at least a dozen visible openings bored into the base of the nearby mountain. Oh was taken to the most heavily guarded of the openings. There, he climbed out of the vehicle and rubbed his lower back as he left his driver behind and made his way past the sentries, barely acknowledging their salutes.

      A well-lit passageway, paved and large enough for a semi-truck to pass through, led him fifty yards deep into the mountain before giving way to a large subterranean bunker the size of an airplane hangar. Unseen generators powered banks of overhead lights that bathed the chamber in a glow so bright that Oh had to squint. Portions of the surrounding walls consisted of bare rock, but for the most part the enclosure—floors, walls and ceiling—was lined with a four-foot-thick layer of reinforced concrete. The far wall had been partitioned off with a row of prefabricated offices and laboratories, and to the general’s right was a two-story housing facility every bit as full of amenities as the concentration camp barracks were deprived. Oh had stayed in one of the officers’ quarters a few months earlier when he’d overseen the initial construction of the bunker facilities, and it heartened him to know there would be a warm bed waiting for him once he’d completed his inspection.

      Oh strode to his left, bootheels clomping loudly on the concrete, until he reached the chamber’s storage area. There, concealed inside thick, cylindrical metal canisters mounted to large, seven-axle transporters, were six Taepo Dong-4 intercontinental ballistic missiles. The missiles, three generations removed from the two-stage, Scud-derived, Taepo Dong-1 that North Korea had lobbed into the Sea of Japan back in 1998, had been originally manufactured a hundred miles to the north at the army’s R&D facilities in Sin’gye. Once built and deemed operative, the ICBMs had been dismantled and, over the course of the past three months, using circuitous routes and staggered delivery schedules, Oh had seen to it that the armament had been transferred, one by one, to Changchon. The final missile had arrived two days earlier and reassembly had been completed only a few hours before the general’s arrival.

      Oh was looking over the missiles when he was joined by Major Jin Choon-Yei, a short, lean career army officer in his early sixties. Jin, a long-time colleague of Oh’s, had taken charge of operations at Changchon when the general had been called back to Pyongyang, and the major had supervised the site’s transformation into the primary hiding place for North Korea’s nuclear arsenal. Prisoners at the concentration camp, along with Lieutenant Corporal Yulim and the camp’s security force, had been kept in the dark about the nature of the facility and construction had been carried out by military inductees and trusted private contractors.

      “Things are coming along nicely, yes?” Jin remarked after the men exchanged greetings.

      Oh nodded. “So far, so good. What about the warheads?”

      “Over here.”

      Jin led Oh past the missiles to a garage-size steel vault imbedded in the mountainside. The door to the vault was closed and guarded by a pair of sentries who stood as rigid as statues, diverting their gazes from the two officers.

      “We have four warheads ready for deployment,” Jin told the general, pointing past the sentries at the safe. “The others, as you know, are en route from Yongbyon and Pyongyang.”

      Oh nodded. “The next shipment should arrive by tomorrow morning, with the others to follow soon after.”

      “We’ll be ready for them,” Jin assured the general.

      “Good,” Oh said. “There’ve been no problems, then? No setbacks?”

      “None,” Jin said. “The closest thing we have to a problem is some crumbling of the bedrock where we didn’t encase it in concrete. It’s very minor, though.”

      The major pointed, dragging Oh’s attention to the area where the warhead vault was imbedded into the raw cavern walls. Small heaps of fallen rubble had accumulated on the ground at the base of the vault and Oh could see faint stress fissures in the nearby rock.

      “Keep that monitored,” Oh suggested. “If the fissures widen, I’ll have someone brought in to see if we need to fortify the rock.”

      “It probably wouldn’t be a bad idea,” Jin conceded.

      Oh made a mental note to call the KPA’s Corps of Engineers regarding the matter, then quickly turned his thoughts to other matters.

      “Now, then,” he said, “what about the launch site?”

      “I just spoke to your nephew and he says things are coming along,” Jin reported. “And the access tunnels are close to merging, as well.”

      “Already?” Oh was pleasantly surprised. He’d made a point not to pry into his nephew’s handling of construction at the missile base, and it appeared now that his faith in the younger man’s talents had paid off.

      “Here,” Jin said, leading Oh away from the site, “let me show you.”

      Jin’s office was located in the first of the prefab rooms situated along the far wall. Once they’d entered the room, the major directed Oh’s attention to a bulletin board mounted on an easel across from his desk. Tacked to the board was a topographical map of South Pyongyang Province, which was bordered to the west by the Yellow Sea and to the south by the demilitarized zone separating the two Koreas. Two thick lines drawn with a marking pen snaked through the Changchon Mountain Range. The longer line, stretching for nearly seven miles, wound its way south from the facility. The second line was far shorter, barely a quarter-mile long, reaching northward from Kijongdong, a controversial North Korean installation located just north of the DMZ. A barely discernible gap marked where the two lines would eventually intersect.

      “We’ve been working around the clock in both tunnels,” Jin told Oh. “If all goes well, by morning the tunnels will have connected. Once that happens, it will only be a matter of widening a few stretches and clearing away debris, then we can haul the missiles and warheads to the launch site.”

      Oh smiled faintly. From the sound of it, they would achieve launch capacity within a week, well ahead of even the most optimistic projections made a few months ago. Kim Jong-il would be pleased.

      “I’ll check the tunnels in the morning,” the general told Jin. “In the meantime, I’m exhausted.”

      “Your room’s the way you left it,” Jin assured him.

      “Good,” Oh said. “Before I retire, though, I was wondering. My back has been acting up and I forgot my medication. If you could help me out…”

      The major smiled indulgently and went to his desk, unlocking one of the side doors. He removed a vial and handed it to the general. “This should take care of the pain and help you sleep.”

      There was no label on the vial, but Oh knew the capsules were filled with doses of morphine, a byproduct of the rehabilitation center’s heroin operations. Oh thanked Jin and quickly helped himself to one of the capsules. He was about to excuse himself so that he could get to his quarters before the morphine kicked in when Jin broadsided him with a pointed query.

      “Forgive me for bringing this up, General,” the major said. “I know things seem to be going well, but I’ve been hearing certain rumors about the missiles. About how well they might perform.”

      Oh’s smile faded as quickly as it had appeared. He turned to Jin, eyes flashing with irritation.

      “What rumors?” he demanded.

      Jin blanched. He took an involuntary step backward and stiffened.

      “Forgive
