In Meg's control room, as Quijana had aboard Orca, Chu had ordered his main screen split for a vertical display.
Mixed bag, he thought, looking at it. One of the Gallic torpedoes is searching upward; but the other is gradually spiraling down to where I think Orca's at. Our double hull and the cones that connect the two give pretty good scattering from active sonar, but if the torpedo comes close enough it will see Quijana. And there's not a lot I can do about that.
The frustration Chu felt at having a comrade under attack and being helpless to intervene caused a tight knot in the sub skipper's stomach.
I could attack Charlemagne, and probably draw off her escorts hunting Orca. But that would let them know we've a sub that can sneak right through their screens. Ruin the whole point of the exercise, that would. Shit.

The ocean floor below was far deeper than the sub's even theoretical crush depth. There'd be no escape in hiding among the clutter of sea bottom.
"The torpedo still hunting us just broke into our level, skipper," sonar announced.
Can't go down much; can't stay here.
"Inflate the rubbers, fore and aft," Quijana ordered. "Just enough for a mild positive buoyancy. I want to put the thermal layer between us and that torpedo. Level off just after we pass the thermal."
"Aye, skipper," helm answered. After a few minutes, the nose down angle the sub had taken on reversed itself as the bow began to ascend. The movement was so slow that, other than for the reversal, there was no sense among the crew of ascending.
Another quick glance at the right side of the main screen showed that the other torpedo, the one that had gone high, was still patrolling in a spiral and still actively pinging.
In some ways the screen was a distraction, presenting, as it did, a three dimensional problem in two dimensions. Quijana closed his eyes and tried to imagine the totality of the situation, with frigates hunting above, helicopters dipping above that, a barrage of sensors having been placed between him and the carrier, and probably another being dropped somewhere by now.
If we hadn't taken out the sub their primary effort would have been protecting the carrier. As is, and with us having dived so low, they probably think the carrier's safe enough. That means their major effort is going to be revenge. Well . . . I suppose I could understand that. The first barrage of sonabuoys was generally south. If they're putting one in now, it's probably north to keep us from heading to port and safety. So we head where? East or west, I think, but which?
West brings us nearer Santander; east there's not a decent port for two hundred miles. But we've got the endurance, easily, for either.
East or west? West or . . .
Yermo's voice was strained, if not shocked. "Skipper, the torpedo found us. Pinging like a bitch and making fifty knots for us. I make it impact in ninety seconds."
"Deception pod," Quijana ordered instantly. "Set for no delay. Dive! All dive!"
Torpedo Number Three, Shimmering Sea
What with the need to pack sonar, both active and passive, propulsive gear and fuel, fuses, MAENAD, controls, and—by no means least—explosive into the torpedo, the room left over for a brain left the thing something of an electronic moron. Even a moron, though, can sometimes be right.
Number three noted the greater sonar return from the pod's bubbles, the simulated engine noise, and the artificial magnetic and electronic signature. It noted them and ignored them. It already had a target and anything that seemed like a better one was likely to be false. Still pinging happily at finding its purpose in life, torpedo three closed the distance to the Orca.
Pingpingping. Oh, joy! Oh, happiness!

"Three's ignoring the pod, skipper," Yermo said. "And Number Two is heading toward the pod. That brings it toward us."
Weapon's fingers moved over his station in a blur. "I can intercept," he announced.
"Do it!" Quijana ordered.
Weapon's finger lanced down, pressing a button to fire one of the remaining rear-facing torpedoes. A shudder ran through the sub as the torpedo launched itself, breaking through the plastic film that separated its distilled water from the salty sea. This was not a supercavitator, but a more conventional design, capable of, at most, fifty knots.
Weapons kept the torpedo on passive sonar only, with its point of aim set on the constantly pinging Gallic intruder. His hand wrapped around a stick control, not dissimilar to a computer gamer's, with a trigger to fire the wire-laying torpedo should it fail to detonate on its own when close enough to its target. He flipped off a red safety cap over the trigger, then straightened his finger.
Seconds later, Yermo said, "They heard the launch upstairs. We're getting active sonar from one of the ships and . . . another one has fired. At least two helicopters dipping now and I'm getting plonks as something is dropping passive sensors above us.
The sub suddenly lurched with two massive, nearly simultaneous explosions behind it.
"I got it!" Weapons exulted.
Quijana looked against at the main screen, now showing the pod, torpedo two aiming for it, and another torpedo just launched from the surface.
"Two has decided to ignore the pod," Yermo said. "I think it's got a lock on us. And . . . another surface ship has launched."
"Bring us down another two hundred," Quijana said.
"We've never tested it that deep, skipper," Garcia warned. "Worse: If we go too much lower we'll hit the critical point for the ammonia. Do that and we can't push out the ballast."
Quijana pointed at the screen and said, "See those. If we don't lose them we're dead anyway."
D 466 Portzmoguer, Gallic Navy, Shimmering Sea, Terra Nova
With all the noise going on below, the frigate had only an uncertain idea of where the Balboan submarine really was. It showed the most amazing ability to maneuver without its engines. The captain was fairly sure they were diving and rising, and using that motion to glide with the dive planes.
Could it get as much as a ten or twelve to one glide path ratio? Casabianca wondered. That could put it two or more kilometers away from our last sighting and with no more sound than comes from breaking through a thermal layer. And that's not much. Twelve to nineteen square kilometers of ocean to hide in, too. Maybe more if we didn't have a perfect lock on it to begin with.
Maybe if we blanketed the sea, launch nearly everything we have, all at once, we might get it. Fire a pattern of Ulysses rocket launched torpedoes . . . maintain guidance via digital link to the buoys they leave at the surface and through the wires they drag behind them. We could do that. Of course, one might break its wire and go hunting another but we've plenty of weapons and they've only the one submarine.
And I might suggest that to the admiral, if I had a better idea of where it is, or even how deep it is.
