The captain climbed to the top of the tower and squeezed through the thirty-one-inch-diameter opening. His flotation vest made for a tight fit and he had to wriggle to get through. He ran his fingers along the seal to make sure it was clean, then secured the hatch cover and descended into the confined control area. The space was made even more cramped by the dials, gauges and instruments that covered every square inch of the walls and overhead.
The captain was a man of unassuming appearance who could have passed for an Ivy League college professor. A nuclear engineer by training, Logan had commanded surface ships before being assigned as the officer in charge of the NR-1. He was of medium height and build, with thinning blond hair and a slight fleshiness around the jaw. The navy had long ago dispensed with the rawboned John Wayne type who ran a ship by the seat of his pants. With computerized firing controls, laser guidance and smart missiles, navy vessels were too complicated and expensive to entrust to cowboys. Logan had a sharp mind and the ability to make a lightning-quick analysis of the most complex technical problem.
His previous commands had been much bigger, yet none came close to the NR-1 in the sophistication of her electronics. Although the boat had been built in 1969, she was constantly upgraded. Despite her cutting edge technology, the sub still used some older but time-tested techniques. A thick twelve-hundred-foot towline ran from the support vessel's deck to a large metal ball clutched by metal jaws on the submarine's bow.
Logan gave the order to release the towrope, then he turned to a thickset bearded man in his fifties and said, "Welcome aboard the smallest nuclear submarine in the world, Dr. Pulaski. Sorry we don't have more elbowroom. The shielding for the nuclear reactor takes up most of the sub. My guess is that you'd prefer claustrophobia to radiation. I assume you've had a tour."
Pulaski smiled. "Yes, I've been checked out on the proper procedure for using the head." He spoke with a slight accent.
"You might have to stand in line, so I'd go easy on the coffee. We've got a ten-man crew, and our facilities can get busy."
"I understand you can stay submerged for up to days," Pulaski said. "I can't imagine what it must be like sitting on the bottom a half-mile down for that length of time."
"I'd be the first to admit that even the simplest task, such as taking a shower or cooking a meal, can be a challenge," Logan said. "Luckily for you, we'll only be down a few hours." He glanced at his watch. "We'll descend one hundred feet to make sure all systems are working. If everything checks out, we'll dive."
Logan stepped through a short passageway slightly wider than his shoulders and indicated a small padded platform behind the two chairs in the control station. "That's normally where I sit during operations. It's all yours today. I'll take the copilot's seat. You've met Dr. Pulaski," he said to the pilot. "He's a marine archaeologist from the University of North Carolina."
The pilot nodded and Logan slid into the right-hand chair beside him. In front of him was a formidable array of instruments and video display screens. "Those are our 'eyes,' " he said, pointing to a row of television monitors. "That's the bow view from the sail cam on the front of the sail."
The captain studied the glowing control panel and after conferring with the pilot, he radioed the support ship and said the sub was ready to dive. He gave the order to submerge and level off at one hundred feet. The pump motors hummed as water was introduced into the ballast tanks. The rocking motion of the sub ceased as she sank below the waves. The sharp bow pictured on the monitors disappeared in a geyser of spray, then reappeared, looming dark against the blue water. The crew checked out the sub's systems while the captain tested the UQC, an underwater wireless telephone that connected the sub with the support ship. The voice from the ship had a drawling, metallic quality but the words were clear and distinct.
When the captain was assured all systems were go, he said, "Dive, dive!"
There was little sensation of movement. The monitor pictures went from blue to black water as the sunlight faded, and the captain ordered the exterior lights on. The descent was practically silent, the pilot using a joystick to operate the diving planes, the captain keeping a close eye on the deep-depth gauge. When the sub was fifty feet above the bottom, Logan ordered the pilot to hover.
The pilot turned to Pulaski. "We're in shouting distance of the site we picked up with remote sensing. We'll run a search using our side-scan sonar. We can program a search pattern into the computer. The sub will automatically run the course on its own while we sit back and relax. Saves wear and tear on the crew."
"Incredible," Pulaski said. "I'm surprised this remarkable boat won't analyze our findings, write a report and defend our conclusions against the criticism of jealous colleagues."
"We're working on that," Logan said, with a poker face. Pulaski shook his head in mock dismay. "I'd better find another line of work. At this rate, marine archaeologists will be doomed to extinction or to simply staring at television monitors."
"Something else you can blame on the Cold War."
Pulaski looked around in wonderment. "I never would have guessed that I'd be doing archaeological research in a sub designed to spy on the Soviet Union."
"There's no way you could have known. This vessel was as hush-hush as it gets. The amazing part is that the ninety-million-dollar price tag was kept a secret. It was money well-spent in my opinion. Now that the navy has allowed her to be used for civilian purposes, we have an incredible tool for pure research."
"I understand the sub was used in the Challenger space shuttle disaster," Pulaski said.
Logan said, "She retrieved critical parts so NASA could determine what went wrong and make the shuttle safe to fly. She also salvaged a sunken F-14 and a missing Phoenix air-to-air missile we didn't want anyone getting their hands on. Some of the stuff involving the Russians is still classified."
"What can you tell me about the mechanical arm?"
"The manipulator works like a human arm, with rotation at all the joints. The sub has two rubber wheels in the keel. It's not exactly a Harley-Davidson motorcycle, but it allows us to move along on the seabed. While the sub rests on the ocean floor, the arm can work a nine-foot radius."
"Fascinating," Pulaski said. "And its capacity?"
"It can lift objects up to two hundred pounds."
"What about cutting tools?"
"Its jaws can cut rope or cable, but they can also hold a torch if the job is tough. As I said, very versatile."
"Yes, evidently," Pulaski said. He seemed pleased.
The sub had been moving in a classic search pattern, back and forth in a series of parallel lines, like mowing a lawn. The monitors showed the seafloor moving beneath the submarine. Vegetation was nonexistent.
Logan said, "We should be closing in on the location we spotted from above." He gestured at a screen. "Hul-lo. Looks like the side scan picked up a hit." He turned to the pilot. "Resume manual control and bring her down around twenty degrees to port."
With gentle bursts of the thrusters, the NR-1 glided on a shallow angle. The battery of two dozen exterior lights illuminated the sea bottom with a sun-bright intensity. The pilot adjusted ballast tanks until the sub achieved neutral buoyancy.
"Hold steady," Logan said. "We're coming into visual contact with our target." He leaned forward and peered intently at the screen, his features bathed in the blue-green light. his the sub moved forward, bulbous shapes appeared on the screen, singly at first, then in groups.
"Those are concentrations of amphorae," Pulaski said. The clay jars for wine or other liquid cargo were often found on ancient sunken ships.
"We've got the still and video cameras making a three-dimensional record for you to analyze later," the captain said. "Is there anything you'd like to retrieve?"
"Yes, that would be wonderful. Can we bring up an amphora? Maybe from that pile."
Logan ordered the pilot to put the sub on the bottom near a pile of clay jars. The four-hundred-ton vessel touched down like a feather and rolled forward. The captain called for the retrieval crew.
Two crewmen came forward and lifted a hatch in the floor behind the control area. Beneath the hatch was a shallow well. A trio of four-inch-thick acrylic viewing ports in the floor offered a view of the bottom. One man squeezed into the space and kept watch so the sub wouldn't run into the pile of jars. When the targets were within reach, the sub stopped. The manipulator arm was housed in the forward end of the keel box. Using a portable control panel, the man in the well extended the arm and worked the jaws. The arm rotated at the shoulder.
The mechanical hand gently grabbed a jar around the neck, lifted and placed it in a storage basket below the bow. The arm was retracted and Logan ordered the crew to raise the sub off the bottom. While the sub made another photo run, Logan called the support ship, described their find and said they were about to surface, then ordered the sonar turned on to locate the support ship on the surface. A measured ping-ping echoed throughout the sub.
"Prepare to surface," Logan told the pilot. Dr. Pulaski was standing directly behind the captain's chair. "I don't think so," he said.
Preoccupied with the task at hand, Logan was only half listening. "Pardon me, Doctor. What did you say?"
"I said we're not going to the surface."
Logan spun his chair around, an amused expression on his face. "I hope you didn't take my bragging about the ability to stay down for a month at face value. We only brought enough food for a few days."
Pulaski slipped a hand under his windbreaker and pulled out a Tokarev TT-33 pistol. Speaking calmly, he said, "You will do as I say or I will shoot your pilot." He brought the weapon around and placed the muzzle against the pilot's head.
Logan's eyes focused on the gun, then darted to Pulaski's face. There was no hint of mercy in the rock-hard features.
"Who are you?" Logan said.
"It makes no difference who I am. I will repeat this only one more time. You will follow my orders."
"All right," Logan said, his voice hoarse with tension. "What do you want me to do?"
"First, switch off all communications with your support ship." Pulaski watched carefully as Logan clicked all the radio switches off. "Thank you," he said, checking his watch. "Next, inform the rest of the crew that the sub has been hijacked. Warn them that anyone who comes forward without permission will be shot."
The captain glared at Pulaski as he got on the internal communications system. "This is the captain. There is a man with a gun in the control area. The sub is now under his command. We will do what he says. Stay out of the control area. This is not a joke. Repeat: This is not a joke. Remain at your posts. Anyone coming forward will be shot."
Startled voices could be heard coming from the aft section, and the captain issued the warning a second time to make sure his men knew he was serious.
"Very good," Pulaski said. "Now you will bring the sub up to the five-hundred-foot level."
"You heard him," Logan said to the pilot, as if reluctant to give the direct order.
The pilot had been frozen in his chair. At Logan's command, he reached for the controls and pumped water from the variable ballast tanks. Working the planes, he elevated the sub's nose and moved the NR-1 upward with short bursts of the main propulsion. At five hundred feet, he leveled the sub off.
"Okay," Logan said. "Now what?" His eyes blazed with anger.
Pulaski glanced at his watch like a man worrying over a late train. "Now we wait." He shifted the gun away from the pilot, but kept it leveled and at ready.
Ten minutes passed. Then fifteen. Logan's patience was wearing thin. "If you don't mind, could you tell me what we're waiting for?"
Pulaski put his finger to his lips. "You'll see," he said with a mysterious smile.
Several more minutes passed. The tension was suffocating. Logan stared at the sail cam monitor, wondering who this man was and what he wanted-and the answer was soon in coming. A huge shadow moved beyond the sharply pointed bow.
Logan leaned forward and peered at the screen. "What the hell is that?"
The shadow glided under the sub like a monstrous shark coming up for a belly bite. A horrendous metal clang reverberated from one end of the sub to the other as if the NR-1 had been slammed by a giant sledgehammer. The vessel shivered from the shock and rose several feet.
"We've been hit!" the pilot yelled, instinctively reaching f for the controls.
"Stay where you are!" Pulaski barked, bringing his gun to bear.
The pilot's hand froze in midair and his eyes stared at the overhead. Those in the sub could hear scraping and dragging as if big metal bugs were crawling on the hull.
Pulaski beamed with pleasure. "Our welcoming party has arrived to greet us."
