On AKVs and Survivability

From the questions box:

Dear Gentlesoph,
Having been reading your posts, I have a question about AKVs such as the ‘Daggerfan’ and ‘Slasher’ classes. With high-powered lasers capable of doing damage at one light second, how do AKVs survive the 300,000km journey into single kilometer range? As stated in your ‘Nonstandard Starship Scuffles’ post, military vessels use armor woven through with thermal superconductors dumping heat into ‘thermal goo’. I assume this armor/thermal management system applies to AKVs as well, although you also state that point-defense lasers will shred a vessel unfortunate enough to get into very close range. How can an AKV survive at single kilometer ranges long enough to inflict damage on the target? Thank you for your time, I look forward to more posts!

Well, there are two parts to this: how do AKVs close to skin-dancing range, and how do they survive when they get there? I’ll take ’em one at a time.

On the first point: with great difficulty.

If you take a wing of AKVs and throw them at a fresh battleship, all you’re doing is providing its point-defense computers with skeet; they’ll be chaff and charnel before they get anywhere near the inside of the BB’s point-defense zone.

What you have to do is wear it down first. That’s is the job of the non-carriers on your side of the fight: throw a lot of kinetics at the enemy to make their PD work hard. That does three jobs: one, it keeps the PD grid busy in itself; two, any of it that gets through may just take out a chunk of the PD grid; but most importantly, three, by making them run their point-defenses, you’re building up heat in their ship. Your non-carriers also have the job of pumping heat into their ship directly with the big lasers.

That heat, in turn, is going to eat away at their PD efficiency in a variety of ways. Most simply, it’s going to have to cut back on its firing rate once the heat sinks start filling, because otherwise the crew will cook, but also the hardware becomes less efficient, processor error rates go up, and similar badness ensues.

That’s when you send in the AKVs, and you send in a lot of AKVs mingled with a lot of chaff and decoys, swamping the capabilities of the now-degraded PD grid. They won’t all get through – you plan for a lot of them not to – but once the grid’s sufficiently degraded, enough will to ruin the BB’s day.

As for when they’re there? Remember, they’re described as operating within the point-defense envelope, which is to say, inside its inner boundary, which is defined by the minimum effective range of the PD – set by a variety of factors, such as the range at which firing the PD will seriously damage your own ship, but of which probably the most important is the ability of the PD to track the target and slew to fire on it. At the sort of hug-the-hull sub-km range AKVs like to operate at, it doesn’t take much velocity to generate a huge traversal angle, and what you can’t track, you can’t reliably hit.

(And it’s hard for your screen to fire effectively at the AKVs ruining your day, ’cause even discounting the effects of the AKV exploding at point-blank range, every miss will hit you.)

All of which is to say: While there are some subtleties and complexities to the tactics (defense AKVs, screening vessels sharing PD, etc., etc.), the short answer is it takes a lot of work and losses to get an AKV force within range of a target, but once you do, that target is dead meat.

The Counterrevolution Will Be Televised

combat instrumentation and logging module (CILM): Part of the standard military-basic biomod package, the combat instrumentation and logging module is an enhanced lifelogger, recording tagged sensory recordings as well as physiological information, armor, weapon, and equipment telemetry, and tactical mesh status. The data recorded by the CILM is used to provide contextual data in after-action reports, for targeted improvement of individual performance and fireteam coordination, and in the development of future training scenarios.

Given the Legions’ institutional sense of humor, the CILM is commonly if unfortunately referred to as the “fight data recorder”.

EEEEEEEE

shrieker: (also ping-pedo) a single-shot directional EM pulse generator mounted in a capsule suitable for mass driver deployment.

It is a truism of tactics that active sensors, while much more effective than passive sensors, can rarely be used since they are even more effective at disclosing the user’s position to other vessels. The shrieker represents a compromise with this truism; given effective localization and a little mathematics, there is no necessity for the sensor emitter and the sensor receiver to be in the same location. Thus, it provides the means to implement this by emitting the radar/lidar pulse from a point distant from the launching vessel.

The shrieker is far from a perfect solution. It provides partial information on the location of its launcher, especially if the pre-pulse run is short, or the opposition’s sensors are sufficiently sensitive to pick up Doppler distortion in the emitted pulse; and deployments are limited inasmuch as, although directional, a shrieker can only be used in situations in which its pulse will not illuminate the launching vessel or other friendlies to the passive sensors of the opposition. Nonetheless, the additional information provided by even limited active sensor capability can make all the difference in a tactical situation.

How I Wonder What You Aargh

Cirys superzorcher (n.): A hypothetical weapons system in which the various elements of a Cirys swarm (q.v.) are equipped to function as the radiative elements of a phased-array laser. Such an array, with an effective aperture equal to the diameter of the swarm, would theoretically be able to deliver a substantial portion of the total solar output of the contained star in a single beam against targets located at interstellar distances.

Occasional peaceful uses for such beams have been mooted, including laser sail propulsion (although it should be noted that there is little call for such craft on a larger scale than existing propulsion arrays – which have the advantage of being mobile – can handle, and the ability to build a laser-sail craft capable of surviving such propulsion is questionable), long-distance, including extragalactic, communications (a matter of great interest to the Elsewhere Society), and even remote power generation and delivery.

However, while condemned by Cirys Aendyr himself – who is said to have wept when this application of his concept was brought to his attention – the most common proposal is to use the Cirys superzorcher as the weapons system implied by its name. The ability to place so much power on target (a figure of the order of 108 exawatts for a Hearth-class star) across interstellar distances, capable of vaporizing lithic worlds and severely damaging gas giants and stars, is peculiarly attractive to certain types of mentality, especially when it is considered that the purely photonic beam of a superzorcher is substantially more difficult to detect than a typical RKV, and cannot be practically intercepted or recalled.

As such, while the Cirys superzorcher requires a high degree of technological advancement and autoindustrialism to produce (a potential currently limited to the Empire and certain other Core Markets) and is in any case a prohibited weapons system (classified as a Tier I star-killer under the Ley Accords), an informal consensus exists among the Presidium powers that the construction of such a device by any polity, within or without the Worlds, may be reasonably interpreted as notice of intent to commit gigacide, and as such is a legitimate cause for preemptive defense of the highest order.

Things You Are No Longer Allowed To Do In The Imperial Military Service

This one goes out to all my readers who have spent time deployed somewhere really, really, exquisitely tedious…

From: Master-at-Arms, CS Ablator
To: All Personnel, Task Group SPIKY POTATO
Subject: Prohibitions That Should Not Have To Be Explicit

It has come to my attention that due to the less than challenging nature of our current duty station, certain behaviors qualifying as discipline problems have become alarmingly common throughout this Task Group. Worse, it has come to the Admiral’s attention, and the Admiral, permit me to assure you, is even less amused by them than I am.

From the date of posting this notice, therefore, the following are now explicitly prohibited, and violations will attract the full weight of Article Three to the violator and anyone else involved.

  1. The chief reason for the unchallenging nature of our present duty station is the technical advantage we enjoy over the enemy. The correct military terminology for this, however, is battlespace supremacy. Under no circumstances is it to be referred to in after-action reports as god mode. Good grief, people, you all know that our AARs are matters of public record. Try to show a little professionalism.
  2. Local allies are technically referred to as colonial troops, and not as ablative meat, however lacking their TO&E might be. At least where they can hear you.
  3. Even if the locals have no missiles capable of doing more than bouncing off our ships’ hulls, the tactical tank is for monitoring local-space activity. Not for playing Galaxy of Conquest in super-high-res. (And if you’re the officer Captain Oricalcios walked in on mid-game, your tactics were terrible and you just failed this year’s promotion board.)
  4. The official motto of the Imperial Military Service is “Between the Flame and the Fire”. Unofficially, the paraphrase “civilization has enemies; we kill the bastards” has been usually tolerated. All of the following, however, are to be avoided: “Your sexy new war gods”, “because nuclear ain’t enough”, “death death death death death”, and any references to squid.
  5. Yes, the paderi are a quadrupedal species. This does not mean that our local allies can be used as cavalry mounts.
  6. Even, and I wish to emphasize this in particular, if it was their idea. Even assuming that it is a good idea, the optics are terrible.
  7. Nor are any of our current variety of combat drones suitable for use in this role. You’ll just have to live without valiantly charging down the enemy so you can hit them with your sword.
  8. Even if you have a cavalry sword. Why do you have a cavalry sword?
  9. Your fellow legionaries are not to be used as projectile weapons.
  10. Betting on arm-wrestling with civilians while wearing power-assisted armor is forbidden, even if they are drunk and spoiling for trouble. The local hospitals have started to complain.
  11. Combat stimulators are not to be considered a substitute for esklav, no matter what you think of the mess brew.
  12. Nor, although the Imperial Military Service is relatively permissive where fraternization is concerned, are they to be used to spice up your love life. Surgeon-Lieutenant Aendyr has been issued a blanket authorization to post pictures.
  13. While chameleon coatings can be set to any color and pattern, flames, hot pink, your favorite painting, or last week’s episode of Battle Beyond the Brane are not approved for field use.
  14. Aftermarket speaker systems are not to be fitted to combat exoskeletons. Your AI already provides a perfectly adequate soundtrack.
  15. …even if you did require them to “challenge the enemy to a dance-off”, we have a requisitions procedure for a reason.
  16. No military equipment is to be used for recreational purposes. If whatever you thought of makes you smile, giggle, or laugh, you are to assume that it constitutes recreational purposes until advised otherwise.
  17. Especially if it involves any intersection of stealth hardware with practical jokes.
  18. Yes, cook-outs are recreational. Besides, no heat-generating weapons in inventory can be turned down far enough to leave the meat even slightly edible. Yes, we checked.
  19. So is requisitioning drop shuttles for booze runs or ‘surprise rapid insertion liberty’.
  20. While the IMS recognizes that explosives can be used to solve a remarkable number of classes of problems, and while formal research into expanding this list is usually done by the Office of Military Research and Development it is nonetheless happy to add field improvisations to its official repertoire, this applies to field improvisations. It is not a blanket authorization for unofficial explosives research.
  21. While the Imperial Military Service also has no fan-fiction policy, largely due to no-one ever imagining that it might need a fan-fiction policy, would-be authors are reminded that it still needs to be cleared through all the normal channels before you post it publicly. Especially if you want to illustrate it with staged or real combat videos.
  22. …and if you’re writing that kind of fan-fiction, be aware that at least some of your characters can have you spaced for mutiny.
  23. While your efforts to challenge yourselves are admirable, save it for actual exercises. Pretending you’ve forgotten to bring bullets to the battle so you’ll be forced to improvise may be a challenge, but it’s also a mockery of the rules of war, and just begging for an unpleasant surprise.
  24. Especially if by “improvise” you mean “punch, a lot”.
  25. It’s still a bad idea to play Ancyr roulette even if it’s mathematically impossible for the bullets to penetrate N45 Garrex field combat armor.
  26. …especially if whoever you’re playing it with isn’t wearing N45 Garrex field combat armor.
  27. Unless you’re a psychological warfare specialist, you are not authorized to conduct psychological warfare.
  28. Against either side.

That is all. Or rather, that had better be all, because Ablator has an awful lot of hull that could stand a good cleaning. Six by six?

 

Yeah, Maybe Not That Short

Academician Sesca Galith stepped up behind the podium, and tapped it gently to begin. The audience quieted rapidly as she held up a wickedly-pointed poniard, of oddly-textured metal, with lights gleaming white and amber in its hilt, whose image was repeated on the displayed behind her.

“Presenting, gentlesophs, the latest in field interrogation technology from Eye-in-the-Flame’s cognitive weaponry division. This little tool is our ripknife, a guaranteed instrumentality for extracting information when it is both necessary and urgent. Using a nanitic burning-scan reader, when emplaced in the cerebral cavity of a target via some vulnerable aperture or thinness, the ripknife creates a high-resolution destructive scan of the neural network of their brain’s essential regions, then uploads it via your tactical mesh network to your battlespace command center. There, static mind-state analysis or fork interrogation using our patented NEUROLAUNDRY ™ software will lay your target’s secrets bare within minutes, and relay useful information back to you over the mesh. There is no better way to ensure field data acquisition proceeds rapidly enough to keep you inside the opposition’s command-and-control loop –”

A grizzled kaeth in the audience coughed. “Doc, we’re all just simple mercenaries here. Give us the short version?”

“Find someone knowledgeable on the other side, then stick it through the eye socket and wait until the light turns blue. Ignore the dripping. Then you know what they know. Knew.”

 

Trope-a-Day: Clone Army

Clone Army: Just… don’t.

In its simplest form, where you’re just using cloning technology to replicate military-grade bodies as quickly as you can, it may be valuable. It won’t help you with absolute growth rates, since the expensive part is growing the minds to put in the bodies which is much harder to rush, but if you have noetic backup technology at least you can get your casualties back into the field faster.

If you are actually attempting to run what is functionally a non-divergent fork army, however, this will fail dramatically as soon as anyone notices – because, gee, do you think having your entire army react in the same way to every situation and stimulus might just open up a few security holes?

If you’re really lucky, this won’t get everyone killed.
