Chain of Command – Snippet 35

Chapter Eighteen

26 December 2133 (one hour later) (fifth day in K’tok orbit)

The forty-eight hours following the uBakai attack had been filled with frantic work, first trying to recover survivors from the two disabled destroyers, then making the surviving ships fully operational, and finally trying to find answers.

The big questions were simple. What was wrong with their missiles? How had the uBakai reached out and killed six of their starships? How could they execute their mission with the forces and resources they had left? The smaller, softer question, the one hardly anyone asked out loud, was much more complicated: what were they doing here?

Sam had no answers to any of those questions, even after the briefing from Atwater-Jones. If he would find them anywhere, he thought it would be in the boat and from the crew, not sitting in solitude in his cabin trying to think deep thoughts.

Third Principle of Naval Leadership: Know your subordinates and look out for their welfare.

He was about to set out on a tour through the boat, just to show his face and talk to some of the crew on duty, when his comlink vibrated.

“Captain, here.”

Sir? It’s Lieutenant Filipenko. I think we may have something you should see.

“Something good, I hope. Where are you?”

Port missile room, sir, and yes, it’s good.

Ten minutes later Sam pulled himself through the hatch to the missile room and Lieutenant Filipenko held out her hand to him with two small, shiny metal pieces in it. Sam took them and examined them closely. They appeared to be a single light-weight metal part broken in half, and the broken area on each half was dramatically deformed, almost as if they had melted, but the break was sharp, jagged in places. Whatever had done this had done it violently. He looked up and saw Chief Joyce Menzies by her workbench, watching him with interest. The bench had a partially disassembled missile clamped to its work area.

“Is this your work, Chief?”

“All of us, sir,” she said and glanced at Filipenko. “Me and the lieutenant here, and two of my missile monkeys: Warwick and Guerrero. And Machinist First Hasbrow back in engineering, who set up the horizontal compression machine. Oh, and Ensign Robinette ran the stress numbers for us.”

“Stress numbers, huh? Okay, what am I looking at here?”

“Sir, that’s why our de crisse missiles are all broke-dick-no-workee.”

Filipenko took over. “That is the angular brace for one of the rod aiming sub-assemblies out of that Block Four Fire Lance over on the workbench, sir. It’s why when our missiles detonated the laser beams went all over the place instead of at the target. We’ve got the diagrams up on a workstation over there.”

Sam glanced over and even from two yards away could see a diagram cluttered with parts and notations.

“Just tell me what it means.”

“BuOrd changed the layout of the rod aiming assembly not long before we shipped out,” Filipenko said, “and they re-fitted all our missiles. There were problems in the tests and this was supposed to fix them.”

“Let me guess: it didn’t.”

“It might have, sir, but it made a different one. They moved the angle of these braces and apparently forgot they were only rated to take the stress of the acceleration in their original position, which was perpendicular to the acceleration vector when the missile was fired. They moved the brace about twenty-five degrees off-angle and so when it goes through the firing acceleration, it sheers in half. Then the rods just sort of rattle around up there when the laser pointer tries to align them.”

Sam looked at the metal parts again, looked at the distortion around the break lines, how the metal had changed color…

“You broke this under pressure in the machine shop? How much force does this part have to take, anyway?”

“A little over twenty thousand gees, sir,” Menzies answered.

“Twenty thousand? Are you serious?”

Menzies shrugged. “Zero to twenty-one thousand kilometers an hour in less than a tenth of a second–the math’s pretty simple, sir.”

The part seemed warmer somehow, just from Sam thinking about that sort of acceleration force.

“Okay, what can you do about it?”

Filipenko looked at Menzies and the chief answered. “We’re still looking over these assembly diagrams and the earlier test results. See, we can’t just back-build everything the way it was before, ’cause the tests say they weren’t hitting right most of the time.”

“Re-machine the part to take the strain?” Sam asked.

“Maybe we can manage that, sir. Engineering’s got a pretty good precision-tolerance fabricator. The problem might be weight and space. There are thirty of these de câlice de crisse things in each warhead. Heavier part might be a little bigger, and that could be tricky. A little more weight could mean it’s going to be slower coming out of the pipe, shave maybe a couple hundred klicks an hour off its launch velocity.” She shrugged again.

“I don’t care. Give me missiles that kill, Menzies. If we have to get in closer to launch them, we’ll figure out a way to do it.”

Sam handed the broken pieces back to Filipenko. “Filipenko, Menzies, well done. Let’s get the word out to the rest of the squadron so we can all work on a solution, but my money’s still on you guys coming up with the fix we’ll use. You go ahead and set up the tight beam and do the honors.”

“Yes, sir,” she said, and it was the first time he could remember her saying that with enthusiasm and some pride.

Now that was some good news, and Sam felt his mood lift a little as he headed back forward to officer’s country. One problem down and it wasn’t much past breakfast. Maybe he could line his other problems up and knock them over in just as orderly a fashion.


Vice-Captain Takaar Nuvaash, Speaker for the Enemy, looked at the admiral floating behind the workstation, the admiral he knew to be complicit in the murder of a planetary governor and part of a conspiracy which had launched a war which had already cost hundreds of lives, perhaps thousands when the casualties from the ground combat and the attack at Bronstein’s World were added in.

“Nuvaash, how badly did we damage the enemy?” Admiral e-Lapeela demanded.

Nuvaash closed his eyes for a moment to suppress his warring emotions and order his thoughts.

“Less than we anticipated, but we still materially reduced the capabilities of the enemy squadron. It also revealed a critical weakness: the missiles fired by the Human destroyers failed to hit, without exception, even though several of them evaded our point defense weapons and detonated.”

It was a very good thing–Nuvaash thought but did not say–that they failed to accurately target the uBakai ships. The position of the distant picket destroyers guaranteed that two of them had excellent shots at the fleet as it overshot K’Tok’s north pole, and a low orbit destroyer had also managed to launch its missiles well before Nuvaash would have thought possible. The destroyers’ missiles had proven unexpectedly difficult to destroy.

“That last destroyer we killed seriously damaged our ship and two others,” the admiral said. “Their missiles did not do that. Their point defense lasers did. Why did we not know they had this lethal close-in offensive capability?”

He seemed more distant than he had in the past, as if preoccupied with a different problem.

“The destroyer did not display any new or unknown capability,” Nuvaash said. “Its captain simply used its close defense weapons in a novel manner, as offensive weapons. None of our simulations predicted this because the tactic was suicidal, as was demonstrated by the destruction of the craft.”

That much was true, but he looked away from the admiral. He should have anticipated something like this.

“Humans do not put the same value on life as we do,” the admiral said, “not even their own. A Speaker for the Enemy should understand this.”

“The admiral is correct.”

e-Lapeela gestured dismissively and for a moment returned his attention to his desktop.

The truth was, Nuvaash had never noticed Humans to be any less attached to life than were Varoki. But what in a Varoki would be seen as an act of courage and self-sacrifice was, in a Human, always judged differently by e-Lapeela and others like him, including the new governor of K’tok.

Nuvaash had spent many months with Human staffs when serving on combined fleet exercises. Humans displayed a barely contained nervous energy, like a powerful caged animal, which he had never seen completely unleashed except perhaps in some of their appallingly violent athletic contests. In contrast they possessed enormous capacity for beauty, surrounded themselves with it to the point that it became invisible to them. Nuvaash remembered riding in the lift of a tall office building on Earth and in the lift hearing the most hauntingly beautiful music he could ever remember, music so sweet and melancholy it had nearly reduced him to tears, while the Humans ignored it, or in some cases hummed along. Most of them could whistle or sing, could do so beautifully, and simply took the gift for granted. Didn’t they see what they had?

Nuvaash partly understood e-Lapeela’s aversion to Humans, at least the part based on fear and envy. He felt its tug as well, more strongly of late, But if he let himself become slave to those base instincts, what was to become of him?

“How can a close defense laser do the sort of damage we experienced?” the admiral said, pulling Nuvaash’s thoughts back to the cruiser and the present.

“It was designed in response to the new armored nose caps we began deploying on missiles two years ago, Admiral. It has a diameter of ten meters and a virtual focal array of twenty, which is why the mounts are so clearly visible on the exterior of their destroyers. Some of their cruisers have been refitted with them as well. They emit in the ultra-violet part of the spectrum and the combination of short wavelength and very large focal array gives them considerable power at range.

    The missiles are Mark 14 torpedoes! Good call whoever it was several snippets ago.

    I’m having problems visualising these braces, though. I’d have thought a force straight across it (perpendicular) would have to generate more shear stress than a force partly along it (at 25 degrees) not less. Maybe someone with a better engineering background can explain?

    To lose a couple of hundred klicks an hour the additional wight of the redesigned braces is going to have to be something like 1% of the original weight of the missile. Sounds like Filipenko is being over-pessimistic.

    What kind of a missile needs to do all its acceleration in the first tenth of second?

    • Daryl Saal says:

      One launched by a rail gun?

    • Rocky says:

      > I’m having problems visualising these braces, though.
      Just think of them as T-shaped braces, where the leg is supposed to take the acceleration-load.

      > What kind of a missile needs to do all its acceleration in the first tenth of second?
      Probably one that needs to get out of the way of a ship doing combat maneuvers, but also making it hard to shoot down.

    • Randall Rapp says:

      It probably doesn’t do all its acceleration in the railgun, but the accel from the railgun has to be high or it would be unusably long. At that, its still better than a regular gun because the acceleration is constant along the barrel, while in a regular gun it peaks almost immediately. The advantage of using the railgun is the initial accel is from an external power source from the missile, thereby reducing its size and weight. Its onboard propulsion is probaly mainly for maneuvering rather than additional speed.

      • Randomiser says:

        I had forgotten they used a railgun. But I think the velocity quoted in this snippet is the terminal velocity mentioned in an earlier one. I usually think of a missile as something self-propelled, but this one appears to be something more like a smart shell. Although it must be able to manoeuvre to some degree, because I can’t see a purely ballistic projectile managing to hit very much.

  2. MightyMouse says:

    There is a little miscalculation here: 0 … 21,000 km/h ==> 0 … 5,833 m/s
    This was already stated before: max speed is around 6 km/s.
    To reach this spead in less than 1/10 of a second you need an acceleration rate of about
    60.000 m/s². or about 6100 g.
    This kind of thing happens regularly because 1 hour has 3600 seconds, not only 1000.

    • Terranovan says:

      Slight refinement on the math – Agree with the speed in m/s, but reaching in in 0.1 seconds means dividing by .1, not multiplying. Results in (at that precision) 58,333 m/s2 or 5,952 g.

  3. Mike says:

    See? Not only did Sams not personally find the flaw in the missiles, but he has arranged so that the people who did will be the ones who are seen to get credit for the discovery.

  6. Courtenay says:

    Reading the short story made clear to me what should have been obvious: the space needle is Henderson Field. Of course, I don’t see how it will affect naval operations, which Henderson Field certainly did.

    • Dave Lachlan says:

      The space needle will need to be held both on the ground and in space, so the human fleet will be tethered to that mission. It’s value to both sides is why it will be fought over, even if just to deny it’s resupply capacity to the human forces on K’tok.

  7. Dave Lachlan says:

    So.. if the next encounter is a repeat of the Battle of Cape Esperance, it will see and orbital bombardment and resupply that will be dominated by the surprise that the human missiles now work and more use of the point defense lasers with corresponding human destroyer losses. Prediction 2-3 human DDs destroyed for 1 cruiser destroyed and 2 damaged and a minor (passing) surface bombardment.

    • Richard H says:

      Given how much science fiction authors in general like mining history for their engagements and the fact that this guy has written history books, that seems highly likely.

      Based on my read of wikipedia, though, I think you got the sides backwards there, though. The humans are probably going to lose one destroyer and have another one mission-killed, for one Varoki small ship destroyed and a cruiser damaged but needing to be abandoned later. Odds are the humans will think they got more than they did.

      I’d also put a marker on the identity of the new fleet being reinforcements for the existing Varoki fleet jumping close to the planet and not expecting a human welcoming party.

  8. Courtenay says:

    The author can not follow history too closely. A major influence on the fighting in Guadalcanal is that the Japanese were also fighting in New Guinea, and for much of the campaign, New Guinea had priority over Guadalcanal. There is no such distraction in this book’s situation. Also, Henderson Field meant that the Japanese could not approach Guadalcanal in daylight without suffering exorbitant casualties. I see nothing equivalent in this situation; unless there is something that hasn’t been explained, the enemy should be able to just chase the humans away. Five destroyers? Nah.
