Echoes Of Honor hh-8

by David Weber

She punched more buttons, and Minotaur's holo vanished. A new image replaced it almost instantly—a sleek, lethal shape that looked as if it should have come from deep water with a mouth full of fangs—and all three of the junior officers straightened in their chair as its unconventionality registered.

  The most immediately obvious point about it was that, except for the absence of anything remotely like an airfoil, the sharp-prowed vessel looked more like an enormously overgrown pinnace than a normal LAC, for it lacked the flared, hammerhead bow and stern of all impeller-drive warships. The next point to penetrate was that it had absolutely no broadside weapons bays—or point defense stations. But perhaps the most astounding point of all almost sneaked past unnoticed, for the vessel in that holo image had only half as many impeller nodes as it should have. No LAC was hyper-capable, so there had never been any need to fit them with the alpha nodes of true starships. But for over six centuries, a full strength drive ring for any impeller warship had mounted sixteen beta nodes. Everyone knew that.

  Except that this LAC didn't. There were only eight nodes in each of its rings, although they looked a little larger than they should have been.

  "This, people," Truman said, gesturing once more with the light-pointer, "is the lead unit of the Shrike—class. She masses twenty thousand tons, and, as I'm sure you've noticed," the pointer reached into the HD, "there have been some changes, including the omission of the standard hammerheads. That's because this vessel's primary energy armament is right here." The pointer touched the small ship's sleek prow. "A one-point-five-meter spinal mount equipped with the latest grav lenses," she told them, watching their eyes, "which permits her to carry a graser—not a laser—approximately as powerful as that mounted in our Homer—class battlecruisers."

  Gearman sucked in sharply at that. Not surprisingly, Truman thought. Chase energy weapons were always among the most powerful any warship carried, but the graser she had just described had an aperture fifty-six percent greater than chasers mounted in most light cruisers twice her size. But she'd heard the same reaction from someone in almost every group she'd briefed on the new LACs, and she ignored the sound of surprise and continued in that same Saganami Island voice.

  "The power of this weapon is made possible because it is the only offensive energy weapon she mounts, because her missile armament has been substantially downsized, because her impeller node mass has been cut by forty-seven percent, and because her crew is even smaller than that normally assigned to a LAC. Her entire complement will consist of only ten people, which allows a major reduction in life support tonnage. In addition, her normal reactor mass bunkerage has been omitted."

  She paused, and Gearman looked at her with a very strange expression. She only waited, and finally he shook his head.

  "Excuse me, Ma'am. Did you say her bunkerage had been omitted? "

  "Aside from that required for her reaction thrusters, yes," Truman confirmed.

  "But—" Gearman paused, then shrugged and took the plunge. "In that case, Ma'am, just what does she use to fuel her fusion plant?"

  "She doesn't have one," Truman told him simply. "She uses a fission pile."

  Three sets of eyebrows flew up as one, and Truman smiled thinly. Humanity had abandoned fission power as soon as reliable fusion plants became available. Not only had fusion posed less of a radiation danger, but hydrogen was one hell of a lot easier and safer (and cheaper) than fissionables to process. And, Truman knew, Old Earth's Neo-Luddite lunatics, who'd been doing their level best to abolish the very concept of technology as somehow inherently evil about the time fusion power first came along, had managed to brand fission power with the number of the beast as the emblem of all that was destructive and vile. Indeed, the rush to fusion had been something much more akin to a stampede, and unlike most of the claptrap the Neo-Luddites had spouted, fission power's evil reputation had stuck. Contemporary journalists had taken the negatives for granted at the time, since "everyone knew" they were true, and no popular historian had been particularly interested in reconsidering the evidence since, especially not when the technology was obsolete, anyway. So for most of the human race, the very concept of fission power was something out of a dark, primitive, vaguely dangerous, and only dimly remembered past.

  "Yes, I said 'fission,'" Truman told them after giving them most of a minute to absorb it, "and it's another thing we've adapted from the Graysons. Unlike the rest of the galaxy, they still use fission plants, although they've reduced their reliance on them steadily for the last thirty or forty years. But Grayson—and, for that matter, Yeltsin's asteroid belts, as well—are lousy in heavy metals... and fissionables. They'd bootstrapped their way back to fission power by the time of their Civil War, and by the time the rest of us stumbled across them again and reintroduced them to fusion, they'd taken their fission technology to levels of efficiency no one else had ever attained. So when we added modern, lightweight antiradiation composites and rad fields to what they already had, we were able to produce a plant which was even smaller—and considerably more powerful—than anything they'd come up with on their own.

  "I don't expect anyone to be installing them on any planetary surfaces any time soon. For that matter, I doubt we'll see too many of them being installed in capital ships. But one of the new plants handily provides all the power a Shrike needs, and despite all the bad-history bogeyman stories about fission, disposal of spent fuel elements and other waste won't be any particular problem. All our processing work is being done in deep space, and all we have to do with our waste is drop it into a handy star. And unlike a fusion plant, a fission pile doesn't require a supply of reactor mass. Our present estimate is that a Shrike's original power core should be good for about eighteen T-years, which means the only practical limitation on the class's endurance will be her life support."

  Gearman pursed his lips in a silent whistle at that. One of a conventional LAC's several drawbacks was that its small size prevented it from cramming in anything like the bunkerage of regular warships. RMN battlecruisers could take on sufficient reactor mass for almost four months, but they were specifically designed for long-range, deep penetration raids as well as convoy protection. A light attack craft, on the other hand, was fortunate to be able to stow sufficient hydrogen for a three-week deployment, which made her dreadfully short-legged compared to her betters. But if she only had to refuel every eighteen years—!

  "It sounds impressive, Ma'am," he said after a moment, "but I don't know a thing about fission power."

  "Neither does anyone else off Grayson, Mr. Gearman—outside the teams which have been developing the new piles for us, that is. We only have fully trained crews for ten or twelve of our LACs; the others will be trained here aboard Minotaur and the Hancock Station fleet base, and we've been fully equipped with the necessary simulators. We also have a suitable training cadre from the Jankowski Cartel to help you engineering types ease into things. You'll have about three T-weeks between here and Hancock to get your toes wet, and current plans call for you and your fellow engineers to be properly familiarized with your new equipment within three months, at which time we will begin our actual hands-on training with the LACs." She shrugged. "Ass-backwards, I know. You should have been trained on the new plants before Minotaur's keel was even laid. But even though Project Anzio has been given the highest priority, certain, ah, hardware aspects of it have refused to cooperate as much as we might have wished. And to be honest, some of the security types were always happier with the idea that all the training would take place aboard Minotaur, well away from any prying eyes, and not in simulators aboard a shipyard somewhere."

  She considered—briefly—mentioning the entrenched opposition of certain senior officers who saw the entire LAC concept as a useless diversion of resources and manpower from more practical (and traditional) weapons mixes. But the temptation was brief. None of this trio had the seniority to become involved in that kind of high-level internecine strife, and there was no point in worrying them over it.


  "But if we're not checked out on the power plants, how—?" Gearman began, then cut himself off with a blush. A prudent lieutenant did not press a captain of the list for information she chose not to offer, but Truman only smiled once more.

  "How will we get them aboard without power?" she asked, and he nodded. "We won't," she said simply. "We'll be taking eighteen of them aboard before we leave for Hancock; the remaining units of the wing have already departed for that system, tucked away in the cargo holds of half a dozen freighters. Does that answer your question?"

  "Uh, yes, Ma'am."

  "Good. Now, if you'll look back at the holo," Truman went on, "you'll notice these projections here." The pointer's light beam swept over a series of eight open-mouthed, elongated blisters, just aft of the forward impeller ring and placed so that they aligned with the spaces between the ring's nodes. "These are missile tubes," she told them. "These four—" the pointer tapped "—are anti-ship launchers, each equipped with a five-round 'revolver' magazine. The Shrike only has twenty shipkillers, but she can launch one from each tube every three seconds." It was Stackowitz's turn to purse her lips silently, and Truman's pointer indicated the other four tubes. "These are for counter-missiles, and the reduction in normal missile armament lets us fit in seventy-two of those. In addition, if you'll notice here—" the pointer touched the sleek prow again. "These are point defense laser clusters: six of them, in a ring around the graser emitter."

  "Excuse me, Captain. May I ask a question?" It was Takahashi, apparently emboldened by her earlier response to Gearman, and she nodded to him. "Thank you, Ma'am." He paused for a moment, as if searching for exactly the right words, then spoke carefully. "What I'm seeing here seems to be a huge pinnace or assault shuttle, Ma'am, with all its armament fixed forward." She nodded again, and he shrugged. "Isn't it just a little, um... risky for something as small as a LAC to cross it's own 'T' whenever it fires at an enemy starship, Ma'am?"

  "I'll let your department officers handle the nuts and bolts, Lieutenant," she said, "but in general terms, the answer is yes and no. As presently envisioned, doctrine calls for the Shrikes to approach regular warships at an oblique angle, denying the enemy anything like a down-the-throat or up-the-kilt shot. One reason they were designed with no broadside armament was to avoid weakening their sidewalls with gunports. In addition, I'm sure you've all noticed the reduced number of drive nodes."

  She tapped the forward drive ring with the pointer, and three heads nodded as one.

  "These are another innovation—for now we're calling them 'Beta-Squared' nodes—which are much more powerful than older nodes. In addition, they've been fitted with a new version of our FTL com—one with a much higher pulse repetition rate—which should make the Shrikes very useful as manned long-range scouts. I imagine we'll be seeing something like it in larger ships in the not too distant future. What matters for our present purposes, however, is that the new nodes are very nearly as powerful as old-style alpha nodes, and we've also built much heavier sidewall generators into the Shrike to go with them. The result is a sidewall which is about five times as tough as anything ever previously mounted in a LAC.

  "In addition, these ships are fitted with very extensive ECM and a suite of decoys which cost almost as much as the main hull does. All our simulations say that they'll be very difficult missile targets even at relatively short ranges, and particularly if they're supported by additional decoy and jammer missiles. We're currently looking at whether it will be more effective to provide conventional warships to supply those missiles or whether it will make more sense to load them into the LACs' own tubes at the cost of reducing their load-outs on shipkillers.

  "And finally, the R&D boffins have come up with something really nice for these ships." Truman smiled at her audience like a shark. "As we all know, it's impossible to close the bow or stern aspect of an impeller wedge with a sidewall, right?" Heads nodded once again. "And why is that, Lieutenant Takahashi?" she asked genially.

  The lieutenant looked at her for a moment, with the expression of someone whose Saganami Island days were recent enough in memory to make him wary of leading questions. Unfortunately, she was a senior-grade captain and he was only a junior-grade lieutenant, which meant he had to answer her anyway.

  "Because cutting off the stress bands' n-space pocket with a closed wedge prevents you from accelerating, decelerating, or using the wedge to change heading, Ma'am," he replied. "If you want the math—?"

  "No, that's all right, Lieutenant," she said. "But suppose you don't want to accelerate or decelerate? Couldn't you generate a 'bow' sidewall then?"

  "Well, yes, Ma'am, I suppose you could. But if you did you'd be unable to change—" Takahashi stopped speaking suddenly, and Lieutenant Commander Stackowitz gave a sharp, abrupt nod.

  "Exactly," Truman told them both. "The idea is that LACs will attack single starships in sufficient numbers that it will always be possible for them to close obliquely. The new missile tubes, coupled with the recent improvements in seekers, molycircs that can handle higher-grav vector shifts, and a higher acceptable delay between launch and shipboard fire control's hand-off to the missile's on-board systems, will let them fire effectively at up to a hundred and twenty degrees off bore. That means the Shrikes can engage with missiles—and launch counter-missiles against incoming fire—even on an oblique approach. Once they reach energy range, however, they turn directly in towards their targets and bring up their 'bow' sidewall... which has only a single gunport, for the graser, and is twice as powerful as the broadside sidewalls. That makes it as tough as most dreadnought's sidewalls, people, and according to the Advanced Tactical Course's simulators, a target as small as a bow-on LAC should be much harder to hit than a larger warship engaging broadside-to-broadside even under normal circumstances. When you add the sort of electronic warfare capabilities these ships have, they turn into even harder targets, and the presence—and power—of their 'bow' sidewalls should make them harder to kill even if the bad guys do manage to lock them up."

  She paused for a moment, then went on in a much more somber voice.

  "Nonetheless, a good shot will hit even a difficult target, and if one of these LACs is hit by almost anything, it will be destroyed. So once we commit them to action, we will lose some of them, people. But even if we lose a dozen of them, that's only a hundred and twenty people—a third of a destroyer's crew and less than six percent of a Reliant —class battlecruiser's crew. And between them, those twelve LACs will have twenty-one percent more energy weapon firepower than a Reliant's broadside. Of course, they won't have a fraction of the battlecruiser's missile power, and they have to get to knife range to really hurt the enemy. No one is trying to say they can magically replace capital ships, but all the projections and studies say that they can be a major enhancement to a conventional wall of battle. They should also be able to provide us with a local defense capability that can stand up to raiding Peep squadrons and let us pull our regular capital ships off picket duty, and their range and endurance on station should also make them invaluable for raids behind the enemy's frontier."

  Her three newest subordinates gazed at her, clearly still struggling to take in all the information she'd just dropped on them. But there was a glow in their eyes, as well, as they began to envision the possibilities she'd enumerated... and to wonder what else they could figure out to do with the new units.

  "Captain?" Stackowitz half-raised a hand, asking permission to speak, and Truman nodded. "I was just wondering, Ma'am—how many LACs will Minotaur carry?"

  "Allowing for docking buffers and umbilical service points, the total mass cost per LAC, including its own hull, is about thirty-two thousand tons," Truman said in an almost off-hand tone. "Which means we can only carry about a hundred of them."

  "A hun—?" Stackowitz cut herself off, and Truman smiled.

  "A hundred. The wing will probably be divided into twelve eight-LAC squadrons, and we'll carry the other four as backups," she said. "But I think you can see
what kind of force multiplier we're talking about if a single carrier Minotaur's size can put that many of them into space."

  "I certainly can, Ma'am," Stackowitz murmured, and the other two nodded firmly.

  "Good!" Truman said again. "Because now, people, the trick is to make it all work out as nice and pretty as the planners and the sims say it should. And, of course," she bared her teeth at them, "as nice and pretty as I say it should, too."

  Chapter Four

  "Lord Prestwick and Lord Clinkscales, Your Grace," the secretary said, and Benjamin Mayhew IX, by God's Grace Planetary Protector of Grayson and Defender of the Faith, tipped back in the comfortable chair behind the utilitarian desk from which he ruled Grayson as his Chancellor stepped through the door the secretary politely held open.

  "Good morning, Henry," the Protector said.

  "Good morning, Your Grace," Henry Prestwick replied, and moved aside to allow the fierce-faced, white-haired old man who had accompanied him to enter. The second guest carried a slender, silver-headed staff and wore a silver steadholder's key on a chain about his neck, and Benjamin nodded to him in greeting.

  "Howard," he said in a much softer voice. "Thank you for coming."

  The old man only nodded back almost curtly. From anyone else, that would have been a mortal insult to Benjamin Mayhew's personal and official dignity, but Howard Clinkscales was eighty-four T-years old, and sixty-seven of those years had been spent in the service of Grayson and the Mayhew Dynasty. He had served three generations of Mayhews during that time, and, until his resignation eight and a half T-years before, had personally commanded the Planetary Security Forces which had guarded Benjamin himself from babyhood. And even if he hadn't, Benjamin thought sadly, I'd cut him all the slack there was right now. He looks... terrible.

  He hid his thoughts behind a calm, welcoming expression and waved a hand for his guests to be seated. Clinkscales glanced at Prestwick for a moment, then took an armchair beside the coffee table while the Chancellor sat on the small couch flanking the Protector's desk.
