Chapter Twenty-Two
"Sir, if the Nuncians and Lieutenant Hearns are still on profile and Bogey Three hasn't moved, they'll be coming up on crossover in approximately twenty-seven minutes."
Lieutenant Commander Kaplan's tone was crisply professional, and Aivars Terekhov nodded in acknowledgment of her warning. And also of what she hadn't said; assuming the conditions she'd described, Abigail Hearns' pi
He tilted his command chair back slightly, steepling his fingers under his chin, and contemplated the master tactical plot.
As he'd anticipated, Bogey One and Bogey Two had continued in-system at their creeping velocity of eighty-six hundred kilometers per second for thirteen hours and twenty-two minutes, headed straight for the position Pontifex would have occupied when they arrived. Given that absolutely undeviating approach, it had been even simpler than he'd expected for Kaplan and Midshipwoman Zilwicki to track them, and the Nuncian LAC Grizzly had been duly vectored into position to "detect" the intruders and sound the alert. The bogeys had responded by cracking on a few dozen gravities of acceleration, accelerating along the same heading and trying to get far enough from Grizzly to drop back off her sensors... again, just as he'd anticipated, and he conscientiously kept reminding himself not to get overconfident.
It wasn't an easy thing to remember, at least where the two lead bogeys were concerned. For the last hour and thirty-four minutes Bogey One and Bogey Two-now identified as a Desforge -class destroyer, one of the Havenites' older classes, but still a powerful unit for her type-had been chasing the terrified Rembrandt freighter Nijmegen (so identified by Hexapuma 's transponder code) which had broken from planetary orbit in a foolish, panicky bid to evade them. Only a totally terrified merchant skipper would have fled deeper into Nuncio-B's gravity well, especially starting with a velocity disadvantage of more than eighty-five hundred kilometers per second and a ship whose best possible acceleration was no more than a hundred and seventy KPS.
They'd reacted to their juicy, unanticipated target by going in pursuit at five hundred and thirty-one gravities. The recon drones he'd more than half-feared, despite Bagwell's inspiration, hadn't materialized. Probably because Commander Lewis had cooperated so completely with the EWO's suggestions. No engineer was ever really happy about deliberately overstressing the systems under his care, but Ginger Lewis had seemed to find an unholy delight in the notion.
"Sucking pirates in where we can kill them, Skipper? And all you want me to do is take a few hours off the components?" The attractive engineering officer's smile had been decidedly predatory. "No sweat. And if these really are Peep commerce raiders, that's just extra icing on the cake! Remind me to tell you sometime about my first deployment. I'm in favor of killing as many of the bastards as we can catch!"
Terekhov had made a mental note to follow up and get the details about that first cruise of hers. But whatever had happened on it, she clearly harbored a pronounced distaste for any pirate, and she'd entered into Bagwell's ploy with a vengeance. She'd even added a few wrinkles of her own, including a brief, simulated total failure of the wedge while the bogeys were still too far out to actually see the ship herself.
Terekhov had had Kaplan deploy an additional remote array before Lewis' simulated failure so he could observe Hexapuma 's sensor image directly himself. His array had been a lot closer than the bogeys were, and probably more sophisticated, to boot. But for all that, had he been one of the pursuing pirates and seen what the array had, he would have bought the illusion completely. The heavy flare Lewis had produced by heterodyning two alpha nodes-strictly against The Book, and, despite her enthusiasm, more than a little dangerous, even for someone with her skills-had duplicated the spike of a blown beta node almost perfectly. It had also taken something like three hundred hours off the service life of the nodes in question, but if they nailed a pair of Peep warships operating in the Cluster, Terekhov expected the Admiralty to forgive him for that.
The wedge shutdown which had followed instantly on the heels of the flare had been even better-a true work of art. It had been exactly the right length for a frantic civilian engineer to shunt the blown node out of the circuit, reboot her systems, and bring the wedge back up. If Terekhov had been on Bogey One's bridge, he would have been thoroughly convinced Hexapuma was a limping, staggering, desperate fugitive, ru
The bogeys seemed to have bought it without question, at any rate. They'd been burning along after Hexapuma at that same, steady five hundred and thirty-one gravities' acceleration from the instant they detected his ship, and the range between them had fallen from twelve light-minutes to only seven and a third. " Nijmegen" was up to ninety-five hundred kilometers per second, but the bogeys were up to a base velocity of almost thirty-nine thousand. Hexapuma was just over one and a half light-minutes inside Pontifex's orbit, eight and a half light-minutes from -Nuncio-B, which put the bogeys-at 15.8 light-minutes from the primary-almost exactly forty-eight light-seconds inside the system's hyper limit. Better yet, the acceleration they were turning out was fifty gravities lower than Hexapuma 's standard maximum, and a hundred and ninety-five less than she could turn out if she cut her compensator margin to zero.
The only sour note was that, despite the Mars class's obsolescent power plants, she clearly had at least a late pre-cease-fire compensator. The Mars ships were enormous for heavy cruisers-at 473,000 tons, Bogey One was barely ten thousand tons smaller than Hexapuma -and they paid for that extra mass with sluggish acceleration. Bogey One's observed acceleration already exceeded the max her class had been capable of when they were first laid down, but Peep acceleration rates had been creeping upward even before the High Ridge cease-fire. With the latest pre-cease-fire version, a ship of her size could have pulled a maximum acceleration of six hundred and ten, which would have meant she was currently pulling a bit less than eighty-seven percent of her maximum possible acceleration. If she had the post -cease-fire compensator, her max theoretical acceleration should be about six hundred and thirty gravities, in which case she was pulling a bit under eighty-five percent. The Peeps tended to cut their margins finer than the RMN, accepting the risk of catastrophic compensator failure as the cost of shaving away some of the Alliance's acceleration advantage, so it was possible this ship could have the older compensator.
But Terekhov had to assume he was up against a post-cease-fire compensator, which meant Hexapuma 's theoretical maximum acceleration was only ninety-six gravities higher than Bogey One's. Bogey Two, assuming equal generations of compensators, would have a slight acceleration advantage over Hexapuma , but not much of one. Like the Mars -class cruisers, the Desforge -class destroyers were big ships for their types, with correspondingly lower acceleration rates.
Yet even in a worst-case scenario, with the most modern compensators the Peeps had, there was no longer any way both bogeys could avoid action, given their overtake velocity and the current range.
They undoubtedly had at least a few gravities in reserve, but he couldn't know how many until they showed him, so he had to base his estimates on what he'd already seen. And assuming they'd already been operating at max, it would have taken them two hours and four minutes just to decelerate to zero relative to the system primary. At that point, they would have traveled to within 7.7 light-minutes of Nuncio-B, hopelessly inside the system's hyper limit. Even assuming post-cease-fire compensators, Bogey One would require an hour and forty minutes and be less than nine and a half light-minutes from the primary before she came to rest relative to it. In either case, neither of his targets could possibly escape back across the hyper limit before Hexapuma brought them to action. One of them might be able to avoid close action, if they split up quickly enough and both concentrated solely on ru
He put that shivery, hungry thought aside and made himself consider the possible scenarios.
Even assuming they did have the later compensators and went to maximum military power with a zero safety margin, if Hexapuma turned on them this instant and went to her own max deceleration, they would meet in seventy-one minutes. Hexapuma 's velocity relative to Nuncio-B would be over 20,550 KPS, directly away from the star, while the bogeys would still be traveling towards the primary at 12,523 KPS when their vectors crossed over at zero. They'd be down to a bit over nine and a half light-minutes from the primary, right in the heart of the system hyper limit, and given Hexapuma 's range advantage and the fact that she had a bow wall while the bogeys almost certainly did not, she should manage to blow both of them out of space (assuming that was her objective) long before their vectors ever intersected.
But the most likely scenario was that the bogeys would remain at their current compensator settings and begin decelerating within the next twenty-four or twenty-five minutes. If Hexapuma truly had been the crippled, fleeing freighter she'd taken such pains to portray, they'd have to begin decelerating within that time frame to achieve a zero/zero intercept with her if she continued to "flee." That would take them another ninety-odd minutes, depending on the exact point at which they decided to begin decelerating, and hunter and hunted alike would be traveling at somewhere around 20,200 KPS towards the primary at the moment their vectors merged. Ideally, Terekhov wanted to encourage the bogeys to pursue the "freighter" as long as possible. The shorter the range, and the closer to equalized their velocities, the more devastating his own sudden surprise attack would become.
