"Any time now—one of the fish has capture, sir. I don't know which." Jones moved the phones off one ear, his hand poised to slap the other off. The homing sonar on one torpedo was now tracking them. Bad news. If these were like Mark 48s . . . Jones knew all too well that those things didn't miss much. He heard the change in the Doppler shift of the propellers as they passed beneath the Red October. "One missed, sir. Number one missed under us. Number two is heading in, ping interval is shortening." He reached over and patted Bugayev on the shoulder. Maybe he really was the on-board genius that the Russians said he was.

The V. K. Konovalov

The second Mark C torpedo was cutting through the water at forty-one knots. This made the torpedo-target closing speed about fifty-five. The guidance and decision loop was a complex one. Unable to mimic the computer homing system on the American Mark 48, the Soviets had the torpedo's targeting sonar report back to the launching vessel through an insulated wire. The starpom had a choice of sonar data with which to guide the torpedoes, that from the sub-mounted sonar or that from the torpedoes themselves. The first fish had been duped by the ghost images that the jamming had duplicated on the torpedo sonar frequency. For the second, the starpom was using the lower-frequency bow sonar. The first one had missed low, he knew now. That meant that the target was the middle pip. A quick frequency change by the michman cleared the sonar picture for few seconds before the jamming mode was altered. Coolly and expertly, the starpom commanded the second torpedo to select the center target. It ran straight and true.

The five-hundred-pound warhead struck the target a glancing blow aft of midships, just forward of the control room. It exploded a millisecond later.

The Red October

The force of the explosion hurled Ryan from his chair, and his head hit the deck. He came to from a moment's unconsciousness with his ears ringing in the dark. The shock of the explosion had shorted out a dozen electrical switchboards, and it was several seconds before the red battle lights clicked on. Aft, Jones had flipped his headphones off just in time, but Bugayev, trying to the last second to spoof the incoming torpedo, had not. He was rolling in agony on the deck, one eardrum ruptured, totally deafened. In the engine spaces men were scrambling back to their feet. Here the lights had stayed on, and Melekhin's first action was to look at the damage-control status board.
