Now Yearman knew Chernock hadn't been a lunatic, and he was suddenly thinking about all those orbital defenses with absolute seriousness for the first time. The citizen general watched him unobtrusively from the corner of one eye, wondering if the citizen rear admiral would decide to change his tactical approach now that his threat appreciation had just shifted so radically. But Yearman only nodded slowly, then turned and paced towards the master plot. Chernock watched him go, and then turned cold and bitter eyes on the electronic manikin posing as his friend.
They had been in-system for just over three hours now. Let the damned AI and whoever was running it continue to think it had them fooled. They'd made their turnover to decelerate towards Hades three minutes ago. In another hundred and ninety-two minutes, Yearman would turn to open his broadsides and send the bastard a very different sort of message.
Honor Harrington sat in her command chair and listened to the damage and injury reports coming in from all over her ship. She'd known there would be some, no matter how carefully and thoroughly they'd secured for acceleration. Modern warships simply weren't designed for this kind of maneuver. They didn't have proper acceleration couches at every station, and the people who crewed them weren't used to thinking in terms of locking down every piece of gear against a five-gravity acceleration.
But that was precisely what looked like making this work, she thought, and the reports were both less serious and less numerous than she'd feared when she ordered her ships to do something no warship captain had done in over six centuries.
The reports ended, and she smiled wickedly as Nimitz added his own complaints. He'd been remarkably patient about waiting until the official reports were all in, but he hadn't enjoyed the last half-hour a bit. Treecat g tolerances were considerably higher than those of most humans, just as Honor's was, but that didn't mean Nimitz had enjoyed spending thirty-five minutes weighing three-point-seven times his Sphinxian weight. The fact that it had been much worse than that for Honor's human crewmen, and especially the ones who had spent long enough on Hell to fully acclimate to its .94 g gravity, hadn't made him any happier about it, either, and he let her know it in no uncertain terms.
He bleeked indignantly at her smile, and she lifted him in the crook of her arm, cradling him against her breasts while she tried to radiate a sufficiently contrite apology. He looked up at her for a second or two longer, then made a snorting sound, patted her live cheek with a gentle hand, and forgave her.
"Thanks, Stinker," she told him softly, and let him slide back down into her lap as she turned back to her plot.
Most of her captains had thought she was out of her mind when she first proposed using reaction thrusters to generate an intercept vector. It simply wasn't done. The maximum acceleration a ship like Farnese could attain on her auxiliary thrusters, even if she ran them up to maximum emergency power, was on the order of only about a hundred and fifty gravities, which was less than a third of what her impeller wedge could impart. Worse, those thrusters were fuel hogs, drinking up days' worth of reactor mass in minutes. And to add insult to injury, without a wedge, there was no inertial compensator. Warships had much more powerful internal grav plates than shuttles or other small craft, but without the sump of a grav wave for their compensators to work with, the best they could do was reduce the apparent force of a hundred and fifty gravities by a factor of about thirty.
But Honor had insisted it would work, and her subordinates' skepticism had begun to change as she walked them through the numbers. By her calculations, they could sustain a full-powered burn on their main thrusters for thirty-five minutes and still retain sufficient hydrogen in their bunkers to run the battlecruisers' fusion plants at full power for twelve hours and the heavy cruisers' for almost eight. Those were the minimum reserve levels she was willing to contemplate, and they represented the strongest argument against Operation Nelson. Thanks to the huge StateSec tank farm orbiting Hell, they would be able to completely refill the bunkers of every ship afterward, and twelve hours would be more than sufficient to decide any engagement they could possibly hope to win, but none of her ships would have the reactor mass to run for it if the battle fell apart on them.
Well, I told them it worked for Cortez, she thought wryly. Of course, most of them don't have any idea who Cortez was...
As far as her subordinates' other concerns went, a half-hour at five gravities would be punishing but endurable—most humans didn't begin graying out until they hit six or seven g, and heavy-worlders like Honor had even more tolerance than that. And it would take a ship over three million kilometers down-range and impart a velocity of almost thirty-one hundred KPS. That wasn't terribly impressive compared to what an impeller drive could have done in the same length of time, but it offered one huge advantage.
With no impeller signature, a ship might as well be invisible at any sort of extended range.
On the scale to which God built star systems, active sensors had a limited range at the best of times. Officially, most navies normally monitored a million-kilometer bubble with their search radar. In fact, most sensor techs—even in the RMN—didn't bother with active sensors at all at ranges much above a half-million kilometers. There was no real point, since getting a useful return off anything much smaller than a superdreadnought was exceedingly difficult at greater ranges. Worse, virtually all warships incorporated stealth materials into their basic hull matrices. That made them far smaller radar targets than, say, some big, fat merchantman when their drives were down... and when their drives were up, there was no reason to look for them on active, anyway, since passive sensors—and especially gravitic sensors—had enormously greater range and resolution. Of course, they couldn't pick up anything that wasn't emitting, but that was seldom a problem. After all, any ship coming in under power would have to have its wedge up, wouldn't it?
Stealth systems could do quite a bit to make an impeller signature harder to spot, but they were even more effective against other sensors, and so, again, gravitics became the most logical first line of defense. They might not be perfect, but they were the best system available, and captains and sensor techs alike had a pronounced tendency to rely solely upon them.
But Honor's ships didn't have impeller signatures. She had waited two and a half hours, watching the Peeps and plotting their vector carefully before she committed to the thruster burn. The acceleration period had been as bad as she had anticipated, but now her ships were slicing through space at a steady thirty-one hundred KPS, and she smiled again—this time with a predator's snarl—as she watched their projected vector reach out across her plot. Assuming her initial estimate of the Peeps' intentions had been accurate (and their flight profile so far suggested that it had been), she would cut across their base course some three minutes before they slowed to zero relative to Hell. She would be somewhere between six hundred and nine hundred thousand kilometers from them at the moment their courses intersected... and their bows would be towards her.
The two transports—and that was the only thing those two big, slow ships could be—had dropped back to ride a million and a half kilometers behind the main task group, ready to hand but safely screened against any unpleasant surprises. A single warship—probably a heavy cruiser, and most likely one of the older Sword-class ships, from her impeller signature—had been detached as a close escort for them, but Honor wasn't worried about that. If her maneuver worked, she should be in a position to send enough firepower after them to swat the escort without much difficulty, and all three of those ships were much too far inside the hyper limit for the transports to possibly escape before her cruisers ran them down.
"I see it, but I didn't really think you could pull it off, Ma'am," a quiet voice said, and she looked up to find Warner Caslet standing beside her command chair.
