David Weber - The Shadow of Saganami

"What?" Hegedusic looked at him in astonishment, and Levakonic chuckled harshly.

"I know. They have to've developed an entire new generation of superdense fusion bottles, or something of the sort, to pull that off. We know they're fiendishly good at engineering components down, but there are practical limits. Their initial long-range missiles were apparently a lot bigger than their current-generation birds, so they probably went with improved capacitors on those. Hell, you've seen our latest-generation birds, and you know how big they are. Well, they still have single-drive systems that just happen to last a little longer before burnout; all the rest of the volume's for the juice they need to take advantage of their drive endurance.

"If our reports from Haven are right, the Peeps are still using stored energy for their birds. It's hurting them in areas like magazine capacity, compared to the Manties, and apparently they only managed that much because they were able to reverse engineer the Manties' late-generation capacitors.

"Of course," his smile was vinegar-tart, " all we have since Pierre and Saint-Just got bumped off are rumors and third-party reports. Their new management doesn't seem to like us very much. Which is partly our fault, of course." He grimaced. "They didn't have many samples of the Manties' current hardware after the cease-fire, and we weren't particularly interested in helping them out with their own development programs once the reports on Manty hardware started drying up. They, ah, seem to have long memories out there, and once Erewhon went over to their side with actual working examples of Manty technology, their R and D people pretty much told us to take a hike. So our latest first-hand reports are five T-years out of date, and it's possible all of this is inaccurate as hell.

"But if it isn't, then the Manties are building much smaller long-range missiles than they were. That means they have to've found a better solution than simply using bigger and better superconductor rings. If they're going to cram two-or even three, according to some rumors-complete drive packages into missiles the size of the ones they're supposed to be deploying, they can't have the internal volume to use straight superconductor storage to power the damned things."

"I imagine not," Hegedusic agreed. "But could anybody really build a fusion plant that small?"

"It's theoretically possible. With a powerful enough grav field to do the pinching, it could be done. But the initial power would have to come from a source external to the missile, which would probably mean some tricky modification of the launchers, as well. Anyway," he shook his head, brushing away the speculation, "the point I was going to make is that they have an effectively unlimited powered attack range. They could fire the damned things from five or six light-hours out, accelerate the bastards up to speed, and then program the second stage drive not to kick in until the birds entered attack range of their targets. If they didn't punch the max velocity too high, they wouldn't suffer significant -particle-erosion degradation of their onboard sensor systems during even a very long ballistic flight component."

"Jesus Christ," Hegedusic whispered, and Levakonic snorted.

"No, just damned good engineers," he said sardonically. "And before you get your knickers in as big a twist as I did the first time I heard about them, remember this. A missile's only as good as its fire control, and not even Manties can generate good targeting solutions and handle mid-course corrections from half a solar system away. At the moment, they've got a lot more effective range than they can use, and even if they've been able to squeeze their birds down the way some of our sources report they have, they're paying for it with missles which are significantly larger than ours are. That means lower total numbers of birds in the same magazine space, so it's unlikely they'd fire off the thousands of the things it would require to score a significant number of hits at that sort of range in a fleet action.

"But your shipyard here's another kettle of fish. It can't dodge, and it doesn't have sidewalls. So if all they wanted to do was wreck Eroica Station, they could just fire off a saturation salvo of old-fashioned contact nukes to come whipping in here at seventy-five or eighty percent of light-speed. There's no way you could stop enough of them, especially if they seeded the attack wave with their new penetration aids, and they wouldn't really even have to cross the hyper limit to do it."

"But we don't know they are crossing the limit," Hegedusic pointed out.

"I think they are," Levakonic said grimly. The Monican looked a question at him, and he shrugged. "I think that big bastard is a freighter, Isidor-probably an ammunition ship. They won't want to bring her in where anything nasty could happen to her, so they're decelerating to stay with her while they load up with towed pods. Once they have, she'll stay out beyond the limit, and they'll come on in."

"What makes you so sure?"

"I'm not sure . But they could fire the pods from out there, if they wanted to, and if that is an ammo ship, who the hell cares about onboard magazine space? They've got missiles to burn. They could accept poor targeting solutions if they wanted to this time, so if they're planning on coming on in to a point where they can get better ones, that suggests to me that they want to be sure they hit what they're aiming at rather than simply smashing the entire Station. Which also suggests they'll at least want to talk to you before they kill you, even if they haven't done it yet. And also lends a little extra point to the minor question of just where Commodore Horster is right now."

"All ships report acquisition of all pods, Sir," Nagchaudhuri said.

"Very well. My compliments to Commander Badmachin for a well executed evolution. Remind her to keep an eye on her sensor platforms. If anyone comes at her, we'll meet her at the primary rendezvous."

"Aye, aye, Sir."

"Commander Wright."

"Yes, Sir."

"Resume acceleration and put us on profile for Eroica Station."

"You're right, Izrok; they're coming on in," Hegedusic said. "Which means you've also got a point about Horster." He turned to the communications section again. "Lieutenant!"

"Yes, Sir?"

"I want a directional broadcast away from these people. Get hold of Captain Simons in CIC. Ask him to define the volumes where Commodore Horster's units are most likely to be and then sweep all of them you can without giving these people anything to pick up. Got it?"

"Yes, Sir!"

"Good. Address it to CO First Division and prepare to record."

"Yes, Sir. Ready to record, Sir."

"Very good. Message begins. 'Janko, unknown but presumably hostile units are approaching Eroica Station. My assumption is that they're here to destroy or take possession of the new units, and I don't expect them to rely solely on sweet reason. I know you're out there somewhere. If you're placed to intervene, this would probably be a good time for a live-fire training exercise. I'll stall as long as I can, but if they're who I think they are, there may not be a lot I can do. Remember the Manties' range advantage. If this is a Manticoran squadron, the trick'll be to get into range of them without getting yourself destroyed in the process. If you receive this message and can confirm without revealing your presence to the enemy, do so. If you can't intervene, notify me, regardless of whether or not they can detect your signal. Otherwise, maintain com silence and maneuver at your discretion. Good luck. I think we'll both need it. Isidor, clear and out.'"

He watched the communications officer play the recording back through his earbug. Then the lieutenant nodded.
