“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.”
