"But like you, I was thinking about the hardware side of his report and wishing the Board had been given a chance to see it before it issued its official conclusions," the citizen admiral went on. "Not that it would have convinced the doubters... or even me — fully, I mean — I suppose. It just doesn't seem possible that even the Manties could squeeze a fusion plant, and a full set of beta nodes, down into a LAC hull and then find room to cram in a godawful graser like the one Diamato described, as well!"
"I've never really understood that," Honeker said, admitting a degree of technical ignorance no "proper" people's commissioner would display. "I mean, we put fusion plants into pinnaces, and isn't a LAC just a scaled-up pinnace, when all's said and done?"
"Um." Tourville scratched an eyebrow while he considered the best way to explain. "I can see why you might think that," he acknowledged after a moment, "but it's not just a matter of scale. Or, rather, it is a matter of scale, in a way, but one in which the difference is so great as to create a difference in kind, as well.
"A pinnace has a far weaker wedge than any regular warship or merchantman. It's enormously smaller, for one thing, not more than a kilometer in width, and less powerful. The little hip-pocket fusion plants we put into small craft couldn't even begin to power an all-up wedge for a ship the size of a LAC. Which is just as well, because they use old-fashioned mag bottle technology and laser-fired fusing that's not a lot more advanced than they were using back on Old Earth Ante Diaspora. We've made a hell of a lot of advances since then, of course, in order to shoehorn the plants down to fit into pinnaces, but the way they're built puts a low absolute ceiling on their output.
"Even the biggest pinnace or assault shuttle comes in at well under a thousand tons, though, and a worthwhile LAC has to be in the thirty— to fifty-thousand-ton range just to pack in its impellers and any armament at all. Remember that courier boats in the same size range don't carry any weapons or defenses and just barely manage to find someplace to squeeze in a hyper generator. A LAC may be smaller than a starship, but it still has to be able to achieve high acceleration rates (which means a military grade compensator), produce sidewalls, power its weapons — and find places to mount them — and generally act like a serious warship, or else people would simply ignore it. Which means that, like any starship, LACs need modern grav-fusing plants to maintain the power levels they require. And there are limits on how small you can make one of those."
The citizen vice admiral twitched a shrug.
"Of course, the designers can cut some corners when they design a LAC. For one thing, they don't try to build in a power plant which can meet all requirements out of current generating capacity. Ton-for-ton, LACs have enormous capacitor rings, much larger than anything else's, even an SD. They're a lot smaller in absolute terms, naturally, given the difference in size between the ships involved, but most energy-armed LACs rely on the capacitor rings to power their offensive armament, and a lot of them rely on the capacitors even for their point-defense clusters. And not even a superdreadnought has enough onboard power generation to bring its wedge up initially without using its capacitors. Just maintaining it once it is up, even with the energy-siphon effect when it twists over into hyper, requires a huge investment in power, and initiating the impeller bands in the first place raises the power requirement exponentially. So even when they're not doing anything else, most warships tend to have at least one fusion plant on-line to charge up their capacitor rings... and, of course, a LAC only has one power plant, and just keeping it up and running requires its own not insubstantial power investment.
"And that's why so many of our own shipyard people will tell you that anything like Diamato's `super LACs' is flatly impossible. Either the damned things have to be bigger than Diamato thought they were, or else there's some serious mistake in his estimate of the destructiveness he claims they were capable of handing out."
"I'm a bit confused, Lester," Honeker admitted. "Are you saying Diamato was right? Or that he must have been wrong?"
"I'm saying that by every logical analysis I can come up with, he must be wrong... but that what happened to Jane Kellet argues that he must be right. That's what worries me. Javier Giscard is good, and with all due modesty, I'm not exactly a slouch myself when it comes to tactics. And I've got Yuri and Shannon to help me think about them. But none of us has been able to come up with a way to really defend against the `super LAC,' because none of us can make any rational, useful projections as to what its real capabilities are. And, frankly, I'm almost as worried by what Diamato had to say about the range and acceleration on those damned missiles someone kept shooting up their wakes while the LACs — or whatever — were shooting them from close up and personal. LACs or no LACs, the kind of range advantage that suggests is enough to keep a man from sleeping very soundly at night."
"So you think McQueen is right to be cautious," Honeker said flatly.
"I do," Tourville replied, and his tone was equally flat. Then he shrugged. "On the other hand, I can also understand why some people—" he carefully refrained from mentioning Oscar Saint-Just by name, even now and even with Everard Honeker "—keep asking where the Manty secret weapons are. We've hit them several times since Icarus. Not in any more of their critical systems, granted, but all along their northern frontier, without seeing a sign of anything we didn't already know about. So if they've got them, why haven't they used them? And if they haven't got them, then we ought to be beating up on them as hard and as fast as we can. And if they're in the process of getting them, but don't have them yet, then we really ought to go after them hammer and tongs."
"I see." Honeker regarded the citizen vice admiral speculatively. It must be like pulling teeth for Lester Tourville to even appear to agree with Oscar Saint-Just about anything. Not that Honeker blamed Tourville a bit for that. For that matter, Honeker had come to share a lot of the citizen admiral's reservations about the soundness of StateSec's commanding officer's military judgment.
But one thing Honeker had learned about Tourville was that there was an extraordinarily keen brain behind the wild man facade he was at such pains to project. And if Lester Tourville was genuinely worried by his inability to reconcile the apparently contradictory aspects of the reports from Hancock, Everard Honeker was certainly not prepared to dismiss his concerns.
Whether he understood their technical basis or not.
"So I take it that you approve of the basic Scylla plans," he said after a moment. "Given your desire to get in and beat up on the Manties hard and fast, I mean."
"Of course I do. There's room for us to get hurt, but that's true of almost any operation worth mounting. And the only way we could get hurt too badly would be for the Manties to figure out where we plan to hit them and concentrate everything they can scrape up to stop us. That would require them to be a lot more daring in their deployments than they've been ever since we hit them with Icarus, and I don't see any sign of that changing just yet. Which, of course, gives added point to hitting them now, before they do get around to regaining their strategic balance.
