Tom Clansy - Hunt for Red October

.. zap! What do you suppose they're up to?" "The word from CINCLANT is that their ambassador says they're on a SAR mission for a lost boat." His voice indicated what he thought of that. "Search and rescue, eh?" Reynolds shrugged. "Well, maybe they think they lost a boat off Point Comfort, 'cause if they don't slow down real fast, that's where they'll end up. I've never heard of Alfas operating this close to our coast. Have you, sir?" "Nope." Wood frowned. The thing about the Alfas was that they were fast and noisy. Soviet tactical doctrine seemed to call for them mainly in defensive roles: as "interceptor submarines" they could protect their own missile subs, and with their high speed they could engage American attack submarines, then evade counterattack. Wood didn't think the doctrine was sound, but that was all right with him. "Maybe they want to blockade Norfolk," Reynolds suggested. "You might have a point there," Wood said. "Well, in any case, we'll just sit tight and let them burn right past us. They'll have to slow as they cross the continental shelf line, and we'll tag along behind them, nice and quiet." "Aye," Reynolds said. If they had to shoot, both men reflected, they'd find out just how tough the Alfa really was. There had been much talk about the strength of the titanium used for her hull, whether it really would withstand the force of several hundred pounds of high explosive in direct contact. A new shaped-charge warhead for the Mark 48 torpedo had been developed for just this purpose and for handling the equally tough Typhoon hull. Both officers set this thought aside. Their assigned mission was to track and shadow. The E. S. Politovskiy Pogy-Bait 2 was known to the Soviet Navy as the E. S. Politovskiy. This Alfa-class attack sub was named for the chief engineering officer of the Russian fleet who had sailed all the way around the world to meet his appointment with destiny in the Tsushima Straits. Evgeni Sigismondavich Politovskiy had served the czar's navy with skill and a devotion to duty equal to that of any officer in history, but in his diary, which was discovered years later in Leningrad, the brilliant officer had decried in the most violent terms the corruption and excesses of the czarist regime, giving a grim counterpoint to the selfless patriotism he had shown as he sailed knowingly to his death. This made him a genuine hero for Soviet seamen to emulate, and the State had named its greatest engineering achievement in his memory. Unfortunately the Politovskiy had enjoyed no better luck than he had enjoyed in the face of Togo's guns. The Politovskiy's acoustical signature was labeled Alfa 3 by the Americans. This was incorrect; she had been the first of the Alfas. The small, spindle-shaped attack submarine had reached forty-three knots three hours into her initial builder's trials. Those trials had been cut short only a minute later by an incredible mishap: a fifty-ton right whale had somehow blundered in her path, and the Politovskiy had rammed the unfortunate creature broadside. The impact had smashed ten square meters of bow plating, annihilated the sonar dome, knocked a torpedo tube askew, and nearly flooded the torpedo room. This did not count shock damage to nearly every interior system from electronic equipment to the galley stove, and it was said that if anyone but the famous Vilnius headmaster had been in command, the submarine would surely have been lost. A two-meter segment of the whale's rib was now a permanent fixture at the officer's club in Severomorsk, dramatic testament to the strength of Soviet submarines; in fact the damage had taken over a year to repair, and by the time the Politovskiy sailed again there were already two other Alfas in service. Two days after sailing on her next shakedown, she suffered another major casualty, the total failure of her high-pressure turbine. This had taken six months to replace. There had been three more minor incidents since, and the submarine was forever marked as a bad luck ship. Chief Engineer Vladimir Petchukocov was a loyal Party member and a committed atheist, but he was also a sailor and therefore profoundly superstitious. In the old days, his ship would have been blessed on launching and thereafter every time she sailed. It would have been an impressive ceremony, with a bearded priest, clouds of incense, and evocative hymns. He had sailed without any of that and found himself wishing otherwise. He needed some luck. Petchukocov was having trouble with his reactor. The Alfa reactor plant was small. It had to fit into a relatively small hull. It was also powerful for its size, and this one had been running at one hundred percent rated power for just over four days. They were racing for the American coast at 42.3 knots, as fast as the eight-year-old plant would permit. The Politovskiy was due for a comprehensive overhaul: new sonar, new computers, and a redesigned reactor control suite were all planned for the coming months. Petchukocov thought it irresponsible - reckless - to push his submarine so hard, even if everything were functioning properly. No Alfa plant on a submarine had ever been pushed this hard, not even a new one. And on this one, things were beginning to come apart. The primary high-pressure reactor coolant pump was beginning to vibrate ominously. This was particularly worrying to the engineer. There was a backup, but the secondary pump had a lower rated power, and using it meant losing eight knots of speed. The Alfa plant achieved its high power not with a sodium-cooled system - as the Americans thought - but by running at a far higher pressure than any reactor system afloat and using a revolutionary heat exchange system that boosted the plant's overall thermal efficiency to forty-one percent, well in excess of that for any other submarine. But the price of this was a reactor that at full power was red-lined on every monitor gauge - and in this case the red lines were not mere symbolism. They signified genuine danger. This fact, added to the vibrating pump, had Petchukocov seriously concerned; an hour earlier he had pleaded with the captain to reduce power for a few hours so that his skilled crew of engineers could make repairs. It was probably only a bad bearing, after all, and they had spares. The pump had been designed so that it would be easy to fix. The captain had wavered, wanting to grant the request, but the political officer had intervened, pointing out that their orders were both urgent and explicit: they had to be on station as quickly as possible; to do otherwise would be "politically unsound." And that was that. Petchukocov bitterly remembered the look in his captain's eyes. What was the purpose of a commanding officer if his every order had to be approved by a political flunky? Petchukocov had been a faithful Communist since joining the Octobrists as a boy - but damn it! what was the point of having specialists and engineers? Did the Party really mink that physical laws could be overturned by the whim of some apparatchik with a heavy desk and a dacha in the Moscow suburbs? The engineer swore to himself. He stood alone at the master control board. This was located in the engine room, aft of the compartment that held the reactor and the heat exchanger/steam generator, the latter placed right at the submarine's center of gravity. The reactor was pressurized to twenty kilograms per square centimeter, about twenty-eight hundred pounds per square inch. Only a fraction of this pressure came from the pump. The higher pressure caused a higher boiling point for the coolant. In this case, the water was heated to over 900 Celsius, a temperature sufficient to generate steam, which gathered at the top of the reactor vessel; the steam bubble applied pressure to the water beneath, preventing the generation of more steam. The steam and water regulated one another in a delicate balance. The water was dangerously radioactive as a result of the fission reaction taking place within the uranium fuel rods.Читать дальше
