Deep Space, Sector H-11
June 15, 3400
Rear Admiral Ananya Hazarika sized up the alien she'd invited to pay a courtesy visit to her flagship.
Commodore Pdeudemar of the Eoghan United Commons, CO First Independent Squadron, struck her, and most of the other Umerians who'd met him, as a very friendly being. There was a certain compatibility of national character between the Technocracy and the United Commons: Eoghans loved to ask questions, and Umerians loved to answer them. For those among the Eoghans who spoke Interstellar Standard English, it was a strongly commensal relationship.
They'd just gotten out of a meeting with Fibors aboard
Tate's Folly. Hazarika's shuttle carried them out of the volume Fibors had plunked his task group into, towards the fleet's deployed repair assets. The craft was a VIP transport, not really designed for combat survivability; as such, it had actual windows. And on final approach, there was something to see- they were flying along the length of the Umerian contingent's mobile repair ship, USS
Henry Bessemer.
Bessemer was a big, spindly unit, designed to work on equally big, spindly capital ships. The shorter and blockier cruisers and frigates of her command were dwarfed by the network of mechanical scaffolding and immaterial tractor-pressor mounts holding the ships in place. Drones and teams of human engineers swarmed over the hulls, shrunk to the size of dust motes by distance.
The first ship to appear as they coasted along outside the main repair scaffolds at a few dozen meters per second on final approach was the battered USS
Cairo. An antiship missile fired by one of the pirates' Airaii mercenaries had sheared a trench across her ventral surface, but that on the other side; all Hazarika and the little Eoghan could see was a single neat hole bored through the edge
She frowned. "It's worse than it looks."
"Damage to the interior, the core hull armor?"
"Yes. They're going to have to take her back home; she's a fixed-yard job. Crack open the secondary armor belt and replace a chunk of the interior... they'll practically have to saw her in half lengthwise to make the repairs, then do a proper job bonding the pieces back together. Not something you can do in the field."
"I should think not. Riding in such a ship afterwards... an adventure."
"You think so?"
"I'm surprised you do not, Admiral. I cannot speak for your Technocracy, but Eoghan ships are not designed to be taken apart and put back together so casually."
"I've seen worse. I once served as a tactical ensign on a destroyer that began life as three different ships: one that lost everything forward of Frame 100 to a mine blast, one that lost everything aft of Frame 200 to a reactor mishap, and some miscellaneous bits and pieces from a third that had gone to the salvage yard after a run-in with ork pirates in the Badlands."
"I am amazed you survived the experience."
"What, the accidents? I wasn't on-"
"No, serving on the ship they assembled from the wreckage."
"She was a good ship. You'd never know about her history from looking at her. Officially, the name was
Joseph Murray, but everyone called her
Frankenstein..."
By now,
Cairo was concealed by the bulkhead at the rear of the compartment. The shuttle drew abreast of the light cruiser
Artemisia, giving them a good view of her port flank from a distance of only a few kilometers. Pdeudemar made a curious chittering sound that Hazarika couldn't interpret, but he was clearly looking at the thousands of scorched spots and pockmarks that speckled the light cruiser's side.
The Umerian smiled. "It's not as bad as it looks."
"No penetrating hits?"
"Exactly. Just a flak burst. Lots of superficial damage, but
only superficial. A lot of laser panels destroyed and not much more. For field repairs, all we're doing is epoxying over the dents and replacing the damaged surface features. When we go home they'll probably want to take a good close look at the main armor belt, but that will wait until she can be taken out of service for a few months."
"...So, when will she be ready?"
"A few more days. Similar damage on the other side is being repaired first; they'll get to this one in due time. Once we get the new laser panels back in place, she'll be ready to go."
Having passed the
Empress-class cruiser, they were coming up on her older sister:
Directrix, Hazarika's flagship... at close range, and steadily dropping speed. This time, the extent of damage was obvious. In the final confused beam duel, a plasma bolt had blown away the cruiser's forward torpedo tubes on the port side and kept on going, only stopping after chewing into the port armor belt forward from the inside. The repair ship had already taken hullcutters to that section and pulled it off entirely, leaving a bite out of
Directrix's bow big enough to hold a fair-sized apartment building.
And that wasn't the half of it, as the Eoghan commodore was quick to notice. "Correct me if I am mistaken, Admiral, but from my reading of
Jayne's, isn't there supposed to be a gun turret over on this side, about... there?" The alien twitched his snout at a point on the ship's near side.
Hazarika sighed. "Pdeudemar, this time it's
exactly as bad as it looks. We lost C turret to an anti-ship missile, and the barbette busbars shorted, ah, energetically. Blast was kiloton-plus; we're still not sure
exactly how big. Most of it just arced out into space, and cofferdamming held against the rest, but that arm of the power distribution grid is a total loss. We had to order replacements from home."
"This is not, what did you call it, 'a fixed yard job?'"
"Oh no; since the cofferdams
did hold, we can just drop in a new barbette module and replace the turret. It's doable, but we have to wait for the parts to be shipped to us from the yards, and installation of anything that passes through the core hull is tricky... about three to four more weeks, I'd say. Until then, what you see is what you get."
"It must have been a difficult battle."
"Troubling. Especially that charge at the end, when they went berserk on us..."
"Yes. Atypical behavior for ordinary pirates, though from their numbers these were not ordinary, I would think."
"They weren't. Hell, they even had their own planet, more or less- the big moon around the gas giant. There were a small army of... for lack of a better term, serfs, working the place. Some of those greenhouse complexes would do a decent colony world proud. And the forts around the station; we're still wondering where they got their hands on some of the hardware that went into those platforms. Definitely not your average raiders."
"Some of my people envy you even so. I've got twenty-year veterans bouncing off the walls for something to do."
"Now
that I think I can help you with. My second-in-command will be running another recon cutter sweep close to Zebes in a few days, once we finish repairs to
Artemisia. Some of the Centralist ships will be along too. Perhaps you could dispatch a few of your more excitable crews to join in?"
"It would make my life simpler."
"Let's do it, then."
Force Lord wrote:As well as bringing the same number and classes of ships of Task Force 4, Task Force 3 also brought a battleship and a supercarrier, as well as the experimental battleship CNS Frod, armed with the Type 74-II Ion Cannon along with lesser weaponry. The ship was sent over for testing in combat conditions, despite misgivings from Navy Engineering about the readiness of that weapon.
Fibors, not wanting to risk an embarrasment if the weapon failed, told Captain Stack of the Frod if he was willing to accept Umerian liasons in his vessel. Stack readily agreed, not trusting his own engineers' ability to keep the Cannon functional. Fibors therefore went to his desk and contacted the Umerians through hologram.
CNS Frod
June 20, 3400
Lieutenant Yakichev, Centralist Navy, was waiting in the shuttle bay as the Umerian personnel transport made a quiet and unceremonious landing aboard the battleship
Frod. The first man down the ramp was dressed in something that looked suspiciously like the strike trooper armor he'd seen footage of from Hawk's Nest. Drab, solid-looking plate, with the shimmer of integral force shielding. His helmet was under his arm.
Yakichev recognized the man's face from the files the Captain had forwarded to him. Rear Admiral Hazarika had sent him the chief gunnery NCO in charge of her own flagship's main battery. The Umerian looked around, then nodded towards the lieutenant.
"You Yakichev?"
The Centralist bit down on a rebuke.
He's a Umerian warrant officer; they let their senior noncoms run wild with the junior commissioned officers. He's used to it. And he's a foreign technical specialist who may be here to save my ass. I will NOT treat him like I would some jumped-up spaceman who says the same things, because I will NOT be an idiot.
"Yes, Chief Taglia, I am. I'm here as your liaison with the ship's regular crew. Ah... why are you wearing power armor?" The Umerian looked puzzled for a second, then answered.
"What, this? This isn't combat armor; it's a radiation suit. I figured I was going to need it. When you're working on the big guns, you can't be too careful."
"And the stuff at your waist?"
"Diagnostics, scanning gap micrometer, radiation counters... like I said, I figured I was going to need it."
"Well, I'm under orders to escort you and your team to consult with the specialist crew that manages the Ion Cannon."
"OK. Come on out, gang!" The warrant officer waved his arm in a broad arc, and Yakichev saw a half dozen others following him: similarly armored and equipped. He led them into the heart of the ship, towards the control room for the spinal-mount Type 74-II Ion Cannon.
Captain Stack received the Umerian in his office; having shed his radiation armor, the gunnery officer strode through the door and saluted. He looked... pale and shaken.
The Centralists didn't have the practice of promoting technical specialist noncoms to officer-equivalent rank. As a matter of courtesy Stack chose to treat the Umerian as the senior lieutenant his own fleet deemed him equal to... a valued one.
"Sit down, Mr. Taglia. What did you find on your preliminary inspection?"
"Sir, do I have your permission to speak freely?"
"Yes."
I need to know what he thinks, even if it becomes annoying.
Taglia took a deep breath. "Sir, I'm amazed your ship hasn't blown up with all hands yet. At full beam power, I expect this thing to have a remaining life expectancy on the order of one hour before explosive failure."
"One hour?"
"On the order of one hour. Could be as much as ten hours..."
"Oh."
That's bad, but... how long could a battle last, after we fired this thing up?
"...or, could be as little as six minutes."
Stack said nothing, but his facial expression betrayed his thoughts:
Eeep.
"Exactly, sir."
The captain tapped a few keys on his terminal and brought up a holographic schematic of the Type 74. "What are the danger spots?"
"Well, going by guess and by Geiger counter, I'd say the worst points, where the radiation damage is most severe are-" Taglia looked carefully at the model of the Cannon, then picked up a stylus from the desk to use as a pointer- "here, here, here, here, here... here, here and here... and here. And here and here. And, OK, you might have some problems here, here, here, here, and here. Oh, and definitely here. Also these four points, the first-stage acceleration chambers, here, here, here and here."
That is... a lot of places that might explode. "Ah, for the record, Senior Chief, please explain what you think the matter is."
"Quadrupole alignment."
"I was under the impression that the engineers had been extremely careful about aligning the magnets." Taglia took a deep breath. It seemed as though thinking about the Cannon itself was letting him get his balance back from his earlier rattled state.
"Oh, they did a decent job on the magnet sections themselves. It's the support frames that are the problem. Your shock bracing isn't very good, and you used what looks to be R78 alloy for some of the mountings: also not good. Under high rad flux it transmutes, and you get something that doesn't take heat and magnetic fields well... then it starts warping and you're
really in trouble."
"Trouble?"
"Oh, Klono, yes. Keep this thing running long enough, and you could be looking at twist... hell, up in the milliradian range. Then you get transverse emittance growth, halo starts popping up and you
can't tamp it back down, because you haven't got anything to push it back into longitudinal emittance. So your beam sprouts a halo and that starts scraping off on the pipe walls downstream.
That irradiates the walls. So you're transmuting and radioactivating atoms in the acceleration chamber walls and the magnets, which means they stop being as good a superconductor as they were when you installed them. Then you get eddy currents, which heats the material, and the scrape-off from the beam halo heats the walls even further... sooner or later, it goes above critical temperature and quenches, and... bang."
"So that's what causes an explosion?"
"Well yes, but the explosion, the first few bigajoules, that's just the beginning of your problems. Because once a magnet goes bang, the beam starts getting twisted and sprays all over the inside of the gunline. You get electromagnetic vortices, cascading magnet failure all up and down the line, and you're looking at nuke-range energy releases. Big nukes. That's what
really causes trouble."
"...And how long does this process take, Chief Taglia?"
"What, after the first magnet quenches? Oh, call it twenty or thirty milliseconds, tops. If your circuit breakers aren't good, and your compartmentalization is, you might wind up with as much as a few hundred milliseconds before secondary effects from the explosion kill the power plants; that'll put a stop to the failure sequence no matter what happens. Though by that point, you've gone beyond just "big" nuke-range releases and up into "big enough to choke a Sheppo." I don't know if you guys use antimatter fuel or not, but if you do... well, that'd go up by then too, and then they'd probably have to scoop up the bits of your ship with a Bussard ramjet."
Eeep. "And... have you had this problem often?"
"What? Hmm. There were some problems with the early models of the Mark Eleven way back 'when, and a few times before that, but... not for at least a hundred years."
Captain Stack's voice was strained. "Then
what are we doing wrong?"
"I'm sorry, sir. I don't mean any disrespect, it's not like that. It's just... it's not any one thing. It's a lot of things. Heavy particle guns aren't really harder to build than, say, high-end hyperdrive technology. But like a 'drive, there are a lot of things that go wrong if the engineering isn't good enough to do what the theory says it should. This is an experimental weapon for you; I'm guessing you haven't done much prototyping of lighter versions of the design. There's a lot of stuff you can get away with in a research accelerator or a low-energy beam that flat out does not work at this scale."
"I... see. What are your recommendations here and now, Senior Chief?"
"Pull three quarters of the beam line out and replace it with fresh components; a lot of that stuff down there has already soaked up more radiation than I'd let it stand if it was one of my guns. Component lifetime is always an issue on these things, and it's one of the reasons you have to get so much right to make it work. I mean, this thing would be a viable combat weapon... if you could stop to change barrels every fifteen minutes or so and if nobody hits the hull with anything much over destroyer-grade firepower. And, well, you probably can't count on that."
Changing the beamline... That would take weeks of dockyard work. Not good. "Why didn't my men catch this?"
Another deep breath. "You're sure I can speak freely?"
"Yes, Chief Taglia, you can."
"Then I have to say, your beamline diagnostics are
shit, and I don't think your gun crew understands the problem. I kept asking them about monitoring, modeling software for the magnet controls, adjustable steering solutions... they didn't seem to get it. Probably just down to experience; we learned the hard way how much instrumentation and monitoring it takes to keep these things running smooth. Without that ability to keep an eye on the beam and adjust gun settings on the fly, we'd have barrel lifetime about an order of magnitude worse than it is, and yours... well, you need the diagnostic kit even worse than we do."
"I... see."
"I don't know what else to tell you, sir. I'm sorry."
"Thank you. I'd like a full report, mind, but this was... a much needed dose of realism."
"I do my best, sir. I was scheduled to spend the whole day here, so I can finish up that report."
"Good. Carry on, then." The Umerian saluted again, and withdrew.
This is going to be... difficult to explain to High Command.
