The Hunt for Red October - Tom Clancy [116]

The sonobuoys had limited electrical power and thus limited range. Worse, their supply was finite. The sonobuoy inventory was already being depleted alarmingly, and soon they would have to cut back on expenditures. Additionally, each P-3C carried FLIRs, forward-looking infrared scanners, to identify the heat signature of a nuclear sub, and MADs, magnetic anomaly detectors that located the disturbance in the earth's magnetic field caused by a large chunk of ferrous metal like a submarine. MAD gear could only detect a magnetic disturbance six hundred yards to the left and right of an aircraft's course track, and to do this the aircraft had to fly low, consuming fuel and limiting the crew's visual search range. FLIR had roughly the same limitation.

Thus the technology used to localize a target first detected by SOSUS, or to "delouse" a discrete piece of ocean preparatory to the passage of a convoy, simply was not up to a random search of the deep ocean.

Quentin leaned forward. A circle had just changed to a dot. A P-3C had just dropped an explosive sounding charge and localized an Echo-class attack sub five hundred miles south of the Grand Banks. For an hour they had a near-certain shooting solution on that Echo; her name was written on the Orion's Mark 46 ASW torpedoes.

Quentin sipped at his coffee. His stomach rebelled at the additional caffeine, remembering the abuse of four months of hellish chemotherapy. If there were to be a war, this was one way it might start. All at once, their submarines would stop, perhaps just like this. Not sneaking to kill convoys in midocean but attacking them closer to shore, the way the Germans had done . . . and all the American sensors would be in the wrong place. Once stopped the dots would grow to circles, ever wider, making the task of finding the subs all the more difficult. Their engines quiet, the boats would be invisible traps for the passing merchant vessels and warships racing to bring life-saving supplies to the men in Europe. Submarines were like cancer. Just like the disease that he had only barely defeated. The invisible, malignant vessels would find a place, stop to infect it, and on his screen the malignancies would grow until they were attacked by the aircraft he controlled from this room. But he could not attack them now. Only watch.

"PK EST 1 HOUR—RUN," he typed into his computer console.

"23," the computer answered at once.

Quentin grunted. Twenty-four hours earlier the PK, probability of a kill, had been forty—forty probable kills in the first hour after getting a shooting authorization. Now it was barely half that, and this number had to be taken with a large grain of salt, since it assumed that everything would work, a happy state of affairs found only in fiction. Soon, he judged, the number would be under ten. This did not include kills from friendly submarines that were trailing the Russians under strict orders not to reveal their positions. His sometime allies in the Sturgeons, Permits, and Los Angeleses were playing their own ASW game by their own set of rules. A different breed. He tried to think of them as friends, but it never quite worked. In his twenty years of naval service submarines had always been the enemy. In war they would be useful enemies, but in a war it was widely recognized that there was no such thing as a friendly submarine.

A B-52

The bomber crew knew exactly where the Russians were. Navy Orions and air force Sentries had been shadowing them for days now, and the day before, he'd been told, the Soviets had sent an armed fighter from the Kiev to the nearest Sentry. Possibly an attack mission, probably not, it had in any case been a provocation.

Four hours earlier the squadron of fourteen had flown out of Plattsburg, New York, at 0330, leaving behind black trails of exhaust smoke hidden in the predawn gloom. Each aircraft carried a full load of fuel and twelve missiles whose total weight was far less than the -52's design bombload. This made for good, long range.

Which was exactly what they needed. Knowing where the Russians were was
