What? Padorin stopped reading and started over. He forgot the cigarette smoldering in his ashtray as he reached the bottom of the first page. A joke. Ramius was known for his jokes—but he’d pay for this one. This was going too fucking far! He turned the page.
“This is no joke, Uncle Yuri—Marko.”
Padorin stopped and looked out the window. The Kremlin wall at this point was a beehive of niches for the ashes of the Party faithful. He couldn’t have read the letter correctly. He started to read it again. His hands began to shake.
He had a direct line to Admiral Gorshkov, with no yeomen or secretaries to bar the way.
“Comrade Admiral, this is Padorin.”
“Good morning, Yuri,” Gorshkov said pleasantly.
“I must see you immediately. I have a situation here.”
“What sort of situation?” Gorshkov asked warily.
“We must discuss it in person. I am coming over now.” There was no way he’d discuss this over the phone; he knew it was tapped.
The USS Dallas
Sonarman Second Class Ronald Jones, his division officer noted, was in his usual trance. The young college dropout was hunched over his instrument table, body limp, eyes closed, face locked into the same neutral expression he wore when listening to one of the many Bach tapes on his expensive personal cassette player. Jones was the sort who categorized his tapes by their flaws, a ragged piano tempo, a botched flute, a wavering French horn. He listened to sea sounds with the same discriminating intensity. In all the navies of the world, submariners were regarded as a curious breed, and submariners themselves looked upon sonar operators as odd. Their eccentricities, however, were among the most tolerated in the military service. The executive officer liked to tell a story about a sonar chief he’d served with for two years, a man who had patrolled the same areas in missile submarines for virtually his whole career. He became so familiar with the humpback whales that summered in the area that he took to calling them by name. On retiring, he went to work for the Woods Hole Oceanographic Institute, where his talent was regarded not so much with amusement as awe.
Three years earlier, Jones had been asked to leave the California Institute of Technology in the middle of his junior year. He had pulled one of the ingenious pranks for which Cal Tech students were justly famous, only it hadn’t worked. Now he was serving his time in the navy to finance his return. It was his announced intention to get a doctorate in cybernetics and signal processing. In return for an early out, after receiving his degree he would go to work for the Naval Research Laboratory. Lieutenant Thompson believed it. On joining the Dallas six months earlier, he had read the files of all his men. Jones’ IQ was 158, the highest on the boat by a fair margin. He had a placid face and sad brown eyes that women found irresistible. On the beach Jones had enough action to wear down a squad of marines. It didn’t make much sense to the lieutenant. He’d been the football hero at Annapolis. Jones was a skinny kid who listened to Bach. It didn’t figure.
The USS Dallas, a 688-class attack submarine, was forty miles from the coast of Iceland, approaching her patrol station, code-named Toll Booth. She was two days late getting there. A week earlier, she had participated in the NATO war game NIFTY DOLPHIN, which had been postponed several days because the worst North Atlantic weather in twenty years had delayed other ships detailed to it. In that exercise the Dallas, teamed with HMS Swiftsure, had used the foul weather to penetrate and ravage the simulated enemy formation. It was yet another four-oh performance for the Dallas and her skipper, Commander Bart Mancuso, one of the youngest submarine commanders in the U.S. Navy. The mission had been followed by a courtesy call at the Swiftsure’s Royal Navy base in Scotland, and the American sailors were still shaking off hangovers from the celebration…Now they had a different mission, a new development in the Atlantic submarine game. For three weeks, the Dallas was to report on traffic in and out of Red Route One.
Over the past fourteen months, newer Soviet submarines had been using a strange, effective tactic for shedding their American and British shadowers. Southwest of Iceland the Russian boats would race down the Reykjanes Ridge, a finger of underwater highlands pointing to the deep Atlantic basin. Spaced at intervals from five miles to half a mile, these mountains with their knife-edged ridges of brittle igneous rock rivaled the Alps in size. Their peaks were about a thousand feet beneath the stormy surface of the North Atlantic. Before the late sixties submarines could barely approach the peaks, much less probe their myriad valleys. Throughout the seventies Soviet naval survey vessels had been seen patrolling the ridge—in all seasons, in all weather, quartering and requartering the area in thousands of cruises. Then, fourteen months before the Dallas’ present patrol, the USS Los Angeles had been tracking a Soviet Victor II-class attack submarine. The Victor had skirted the Icelandic coast and gone deep as she approached the ridge. The Los Angeles had followed. The Victor proceeded at eight knots until she passed between the first pair of seamounts, informally known as Thor’s Twins. All at once she went to full speed and moved southwest. The skipper of the Los Angeles made a determined effort to track the Victor and came away from it badly shaken. Although the 688-class submarines were faster than the older Victors, the Russian submarine had simply not slowed down—for fifteen hours, it was later determined.
At first it had not been all that dangerous. Submarines had highly accurate inertial navigation systems able to fix their positions to within a few hundred yards from one second to another. But the Victor was skirting cliffs as though her skipper could see them, like a fighter dodging down a canyon to avoid surface-to-air missile fire. The Los Angeles could not keep track of the cliffs. At any speed over twenty knots both her passive and active sonar, including the echofathometer, became almost useless. The Los Angeles thus found herself navigating completely blind. It was, the skipper later reported, like driving a car with the windows painted over, steering with a map and a stopwatch. This was theoretically possible, but the captain quickly realized that the inertial navigation system had a built-in error factor of several hundred yards; this was aggravated by gravitational disturbances, which affected the “local vertical,” which in turn affected the inertial fix. Worst of all, his charts were made for surface ships. Objects below a few hundred feet had been known to be misplaced by miles—something that mattered to no one until recently. The interval between mountains had quickly become less than his cumulative navigational error—sooner or later his submarine would drive into a mountainside at over thirty knots. The captain backed off. The Victor got away.
Initially it was theorized that the Soviets had somehow staked out one particular route, that their submarines were able to follow it at high speed. Russian skippers were known to pull some crazy stunts, and perhaps they were trusting to a combination of inertial systems, magnetic and gyro compasses attuned to a specific track. This theory had never developed much of a following, and in a few weeks it was known for certain that the Soviet submarines speeding through the ridge were following a multiplicity of tracks. The only thing American and British subs could do was stop periodically to get a sonar fix of their positions, then race to catch up. But the Soviet subs never slowed, and the 688s and Trafalgars kept falling behind.
The Dallas was on Toll Booth station to monitor passing Russian subs, to watch the entrance to the passage the U.S. Navy was now calling Red Route One, and to listen for any external evidence of a new gadget that might enable the Soviets to run the ridge so boldly. Until the Americans could copy it, there were three unsavory alternatives: they could continue losing contact with the Russians; they could station valuable attack subs at the known exits from the route; or they could set up a whole new SOSUS line.
Jones’ trance lasted ten minutes—longer than usual. He ordinarily had a contact figured out in far less time. The sailor leaned back and lit a cigarette.
“Got something, Mr. Thompson.”
“What is it?” Thompson leaned against the bulkhead.
“I don’t
know.” Jones picked up a spare set of phones and handed them to his officer. “Listen up, sir.”
Thompson himself was a masters candidate in electrical engineering, an expert in sonar system design. His eyes screwed shut as he concentrated on the sound. It was a very faint low-frequency rumble—or swish. He couldn’t decide. He listened for several minutes before setting the headphones down, then shook his head.
“I got it a half hour ago on the lateral array,” Jones said. He referred to a subsystem of the BQQ-5 multifunction submarine sonar. Its main component was an eighteen-foot-diameter dome located in the bow. The dome was used for both active and passive operations. A new part of the system was a gang of passive sensors which extended two hundred feet down both sides of the hull. This was a mechanical analog to the sensory organs on the body of a shark. “Lost it, got it back, lost it, got it back,” Jones went on. “It’s not screw sounds, not whales or fish. More like water going through a pipe, except for that funny rumble that comes and goes. Anyway, the bearing is about two-five-zero. That puts it between us and Iceland, so it can’t be too far away.”
“Let’s see what it looks like. Maybe that’ll tell us something.”
Jones took a double-plugged wire from a hook. One plug went into a socket on his sonar panel, the other into the jack on a nearby oscilloscope. The two men spent several minutes working with the sonar controls to isolate the signal. They ended up with an irregular sine wave which they were only able to hold a few seconds at a time.
“Irregular,” Thompson said.
“Yeah, it’s funny. It sounds regular, but it doesn’t look regular. Know what I mean, Mr. Thompson?”
“No, you’ve got better ears.”
“That’s cause I listen to better music, sir. That rock stuff’ll kill your ears.”
Thompson knew he was right, but an Annapolis graduate doesn’t need to hear that from an enlisted man. His vintage Janis Joplin tapes were his own business. “Next step.”
“Yessir.” Jones took the plug from the oscilloscope and moved it into a panel to the left of the sonar board, next to a computer terminal.
During her last overhaul, the Dallas had received a very special toy to go along with her BQQ-5 sonar system. Called the BC-10, it was the most powerful computer yet installed aboard a submarine. Though only about the size of a business desk, it cost over five million dollars and ran at eighty million operations per second. It used newly developed sixty-four-bit chips and made use of the latest processing architecture. Its bubble memory could easily accommodate the computing needs of a whole squadron of submarines. In five years every attack sub in the fleet would have one. Its purpose, much like that of the far larger SOSUS system, was to process and analyze sonar signals; the BC-10 stripped away ambient noise and other naturally produced sea sounds to classify and identify man-made noise. It could identify ships by name from their individual acoustical signatures, much as one could identify the finger or voice prints of a human.
As important as the computer was its programming software. Four years before, a PhD candidate in geophysics who was working at Cal Tech’s geophysical laboratory had completed a program of six hundred thousand steps designed to predict earthquakes. The problem the program addressed was one of signal versus noise. It overcame the difficulty seismologists had discriminating between random noise that is constantly monitored on seismographs and genuinely unusual signals that foretell a seismic event.
The first Defense Department use of the program was in the Air Force Technical Applications Command (AFTAC), which found it entirely satisfactory for its mission of monitoring nuclear events throughout the world in accordance with arms control treaties. The Navy Research Laboratory also redrafted it for its own purposes. Though inadequate for seismic predictions, it worked very well indeed in analyzing sonar signals. The program was known in the navy as the signal algorithmic processing system (SAPS).
“SAPS SIGNAL INPUT,” Jones typed into the video display terminal (VDT).
“READY,” the BC-10 responded at once.
“RUN.”
“WORKING.”
For all the fantastic speed of the BC-10, the six hundred thousand steps of the program, punctuated by numerous GOTO loops, took time to run as the machine eliminated natural sounds with its random profile criteria and then locked into the anomalous signal. It took twenty seconds, an eternity in computer time. The answer came up on the VDT. Jones pressed a key to generate a copy on the adjacent matrix printer.
“Hmph.” Jones tore off the page. “‘ANOMALOUS SIGNAL EVALUATED AS MAGMA DISPLACEMENT.’ That’s SAPS’ way of saying take two aspirin and call me at end of the watch.”
Thompson chuckled. For all the ballyhoo that had accompanied the new system, it was not all that popular in the fleet. “Remember what the papers said when we were in England? Something about seismic activity around Iceland, like when that island poked up back in the sixties.”
Jones lit another cigarette. He knew the student who had originally drafted this abortion they called SAPS. One problem was that it had a nasty habit of analyzing the wrong signal—and you couldn’t tell it was wrong from the results. Besides, since it had been originally designed to look for seismic events, Jones suspected it of a tendency to interpret anomalies as seismic events. He didn’t like the built-in bias, which he felt the research laboratory had not entirely removed. It was one thing to use computers as a tool, quite another to let them do your thinking for you. Besides, they were always discovering new sea sounds that nobody had ever heard before, much less classified.
“Sir, the frequency is all wrong for one thing—nowhere near low enough. How ’bout I try an’ track in on this signal with the R-15?” Jones referred to the towed array of passive sensors the Dallas was trailing behind her at low speed.
Commander Mancuso came in just then, the usual mug of coffee in his hand. If there was one frightening thing about the captain, Thompson thought, it was his talent for showing up when something was going on. Did he have the whole boat wired?
“Just wandering by,” he said casually. “What’s happening this fine day?” The captain leaned against the bulkhead. He was a small man, only five eight, who had fought a battle against his waistline all his life and was now losing because of the good food and lack of exercise on a submarine. His dark eyes were surrounded by laugh lines that were always deeper when he was playing a trick on another ship.
Was it day, Thompson wondered? The six-hour one-in-three rotating watch cycle made for a convenient work schedule, but after a few changes you had to press the button on your watch to figure out what day it was, else you couldn’t make the proper entry in the log.
“Skipper, Jones picked up a funny signal on the lateral. The computer says it’s magma displacement.”
“And Jonesy doesn’t agree with that.” Mancuso didn’t have to make it a question.
“No, sir, Captain, I don’t. I don’t know what it is, but for sure it ain’t that.”
“You against the machine again?”
“Skipper, SAPS works pretty well most of the time, but sometimes it’s a real kludge.” Jones’ epithet was the most perjorative curse of electronics people. “For one thing the frequency is all wrong.”
“Okay, what do you think?”
“I don’t know, Captain. It isn’t screw sounds, and it isn’t any naturally produced sound that I’ve heard. Beyond that…” Jones was struck by the informality of the discussion with his commanding officer, even after three years on nuclear subs. The crew of the Dallas was like one big family, albeit one of the old frontier families, since everybody worked pretty damned hard. The captain was the father. The executive officer, everyone would readily agree, was the mother. The officers were the older kids, and the enlisted men were the younger kids. The important thing was, if you had something to say, the captain would listen to you. To Jones, this counted for a lot.
Mancuso nodded thoughtfully. “Well, keep at it. No sense letting all this expensive gear go to w
aste.”
Jones grinned. Once he had told the captain in precise detail how he could convert this equipment into the world’s finest stereo rig. Mancuso had pointed out that it would not be a major feat, since the sonar gear in this room alone cost over twenty million dollars.
“Christ!” The junior technician bolted upright in his chair. “Somebody just stomped on the gas.”
Jones was the sonar watch supervisor. The other two watchstanders noted the new signal, and Jones switched his phones to the towed array jack while the two officers kept out of the way. He took a scratch pad and noted the time before working on his individual controls. The BQR-15 was the most sensitive sonar rig on the boat, but its sensitivity was not needed for this contact.
“Damn,” Jones muttered quietly.
“Charlie,” said the junior technician.
Jones shook his head. “Victor. Victor class for sure. Doing turns for thirty knots—big burst of cavitation noise, he’s digging big holes in the water, and he doesn’t care who knows it. Bearing zero-five-zero. Skipper, we got good water around us, and the signal is real faint. He’s not close.” It was the closest thing to a range estimate Jones could come up with. Not close meant anything over ten miles. He went back to working his controls. “I think we know this guy. This is the one with a bent blade on his screw, sounds like he’s got a chain wrapped around it.”
“Put it on speaker,” Mancuso told Thompson. He didn’t want to disturb the operators. The lieutenant was already keying the signal into the BC-10.
The bulkhead-mounted speaker would have commanded a four-figure price in any stereo shop for its clarity and dynamic perfection; like everything else on the 688-class sub, it was the very best that money could buy. As Jones worked on the sound controls they heard the whining chirp of propeller cavitation, the thin screech associated with a bent propeller blade, and the deeper rumble of a Victor’s reactor plant at full power. The next thing Mancuso heard was the printer.
