The Konovalov’s bronze propeller turned more quickly. By shutting down some nonessential electrical systems, the engineers were able to increase speed without increasing reactor output.
On the Pogy, the nearest attack boat, the contact faded, degrading the directional bearing somewhat. Commander Wood debated whether or not to get another bearing with active sonar but decided against it. If he used active sonar his position would be like that of a policeman looking for a burglar in a dark building with a flashlight. Sonar pings could well tell his target more than they told him. Using passive sonar was the normal routine in such a case.
Chief Palmer reported the passage of the Dallas down their port side. Both Wood and Chambers decided not to use their underwater telephones to communicate. They could not afford to make any noise now.
They had been creeping along for a half hour now. Ryan was chain-smoking at his station, and his palms were sweating as he struggled to maintain his composure. This was not the sort of combat he had been trained for, being trapped inside a steel pipe, unable to see or hear anything. He knew that there was a Soviet submarine out there, and he knew what her orders were. If her captain realized who they were — then what? The two captains, he thought, were amazingly cool.
“Can your submarines protect us?” Ramius asked.
“Shoot at a Russian sub?” Mancuso shook his head. “Only if he shoots first — at them. Under the normal rules, we don’t count.”
“What?” Ryan was stunned.
“You want to start a war?” Mancuso smiled, as though he found this situation amusing. “That’s what happens when warships from two countries start exchanging shots. We have to smart our way out of this.”
“Be calm, Ryan,” Ramius said. “This is our usual game. The hunter submarine tries to find us, and we try not to be found. Tell me, Captain Mancuso, at what range did you hear us off Iceland?”
“I haven’t examined your chart closely, Captain,” Mancuso mused. “Maybe twenty miles, thirty or so kilometers.”
“And then we were traveling at thirteen knots — noise increases faster than speed. I think we can move east, slowly, without being detected. We use the caterpillar, move at six knots. As you know, Soviet sonar is not so efficient as American. Do you agree, Captain?”
Mancuso nodded. “She’s your boat, sir. May I suggest northeast? That ought to put us behind our attack boats inside an hour, maybe less.”
“Yes.” Ramius hobbled over to the control board to open the tunnel hatches, then went back to the phone. He gave the necessary orders. In a minute the caterpillar motors were engaged and speed was increasing slowly.
“Rudder right ten, Ryan,” Ramius said. “And ease the plane controls.”
“Rudder right ten, sir, easing the planes, sir.” Ryan carried the orders out, glad that they were doing something.
“Your course is zero-four-zero, Ryan,” Mancuso said from the chart table.
“Zero-four-zero, coming right through three-five-zero.” From the helmsman’s seat he could hear the water swishing down the portside tunnel. Every minute or so there was an odd rumble that lasted three or four seconds. The speed gauge in front of him passed through four knots.
“You are frightened, Ryan?” Ramius chuckled.
Jack swore to himself. His voice had wavered. “I’m a little tired, too.”
“I know it is difficult for you. You do well for a new man with no training. We will be late to Norfolk, but we shall get there, you will see. Have you been on a missile boat, Mancuso?”
“Oh, sure. Relax, Ryan. This is what boomers do. Somebody comes lookin’ for us, we just disappear.” The American commander looked up from the chart. He had set coins at the estimated positions of the three other subs. He considered marking it up more but decided not to. There were some very interesting notations on this coastal chart — like programmed missile-firing positions. Fleet intelligence would go ape over this sort of information.
The Red October was moving northeast at six knots now. The Konovalov was coming southeast at three. The Pogy was heading south at two, and the Dallas south at fifteen. All four submarines were now within a six-mile-diameter circle, all converging on about the same point.
Tupolev was enjoying himself. For whatever reason, the Americans had chosen to play a conservative game that he had not expected. The smart thing, he thought, would have been for one of the attack boats to close in and harrass him, allowing the missile sub to pass clear with the other escort. Well, at sea nothing was ever quite the same twice. He sipped at a cup of tea as he selected a sandwich.
His sonar michman noted an odd sound in his sonar set. It only lasted a few seconds, then was gone. Some far-off seismic rumble, he thought at first.
They had risen because of the Red October’s positive trim, and now Ryan had five degrees of down-angle on the diving planes to get back down to a hundred meters. He heard the captains discussing the absence of a thermocline. Mancuso explained that it was not unusual for the area, particularly after violent storms. They agreed that it was unfortunate. A thermal layer would have helped their evasion.
Jones was at the aft entrance of the control room, rubbing his ears. The Russian phones were not very comfortable. “Skipper, I’m getting something to the north, comes and goes. I haven’t gotten a bearing lock on it.”
“Whose?” Mancuso asked.
“Can’t say, sir. The active sonar isn’t too bad, but the passive stuft just isn’t up to the drill, Skipper. We’re not blind, but close to it.”
“Okay, if you hear something, sing out.”
“Aye aye, Captain. You got some coffee out here? Mr. Bugayev sent me for some.”
“I’ll have a pot sent in.”
“Right.” Jones went back to work.
“Comrade Captain, I have a contact, but I do not know what it is,” the michman said over the phone.
Tupolev came back, munching on his sandwich. Ohios had been acquired so rarely by the Russians — three times to be exact, and in each case the quarry had been lost within minutes — that no one had a feel for the characteristics of the class.
The michman handed the captain a spare set of phones. “It may take a few minutes, Comrade. It comes and goes.”
The water off the American coast, though nearly isothermal, was not entirely perfect for sonar systems. Minor currents and eddies set up moving walls that reflected and channeled sound energy on a nearly random basis. Tupolev sat down and listened patiently. It took five minutes for the signal to come back.
The michman’s hand waved. “Now, Comrade Captain.”
His commanding officer looked pale.
“Bearing?”
“Too faint, and too short to lock in — but three degrees on either bow, one-three-six to one-four-two.”
Tupolev tossed the headphones on the table and went forward. He grabbed the political officer by the arm and led him quickly to the wardroom.
“It’s Red October!”
“Impossible. Fleet Command said that his destruction was confirmed by visual inspection of the wreckage.” The zampolit shook his head emphatically.
