The air in the office of Shephard Orbital Works had changed. A few weeks ago, it had smelled of stale air, industrial lubricant, and the solitary quiet of a man waiting for the universe to finally open its eyes and notice his potential. Now, it smelled of pepperoni pizza, ozone, over-steeped green tea, and the distinct, electric sharpness of frustration.
For the last six days, the office had become all but become a lab. Mark used the schematics of a holo table that Marcos had stolen- ahem, "borrowed indefinitely," and used the nanoprinter to print it, installing it in the center of the room. Hovering above it was a wireframe representation of the capacitor bank Mark had been working on. It pulsated with a glowing, deep crimson light that indicated critical thermal overload.
"And... discharge," Mark Shephard said, his voice gravelly with fatigue.
On the display, the simulation initiated the firing sequence. Energy poured from the virtual reactor, surged through the conduits, and hit the capacitor bank. The tri-phase loop engaged, the energy spiraled, compressed, and then-
FZZZT.
The hologram shattered into a cloud of red particles, accompanied by a mournful electronic chime from the terminal.
"You've failed... again," Marcos stated, his voice devoid of sympathy. "Catastrophic containment breach in Sector 4. Estimated yield: 0.5 kilotons. Congratulations, gentlemen, you have just nuked the ship... for the 146th time."
Kenjiro Takagi slammed his hand onto the table.
"It doesn't make sense," Kenjiro hissed, leaning over the table, his eyes scanning the scrolling logs of error data reflecting in his glasses. "The math is perfect. The fractal lattice handles the heat dissipation. The ceramic substrate is superconductive at operational temperatures. The harmonic dampener is tuned to the exact frequency of the feedback loop. So why does it keep fracturing at the intake manifold?"
Mark leaned back in his chair, the leather groaning under his weight. He rubbed his face with a hand and scratched his beard. "Maybe we're pushing too much juice, Kenji. We're trying to get a gunship's capacitors to handle sustained fire that's meant for a frigate."
"No," Kenjiro insisted, pacing the small room. He stepped over a stack of empty pizza boxes and gestured wildly. "The capacity isn't the issue. The simulation holds for 0.4 seconds. It accepts the charge. It's the hold phase where it destabilizes. It's like... it's like the energy has nowhere to sit still. It gets in, panics, and blows the walls out."
Mark watched the smaller man pace. It had been a week since the former SIGS lead engineer had walked into his shop, and in that time, Kenjiro had undergone a transformation. The nervous, corporate shell was gone, and in its place was a manic energy that Mark recognized. Kenjiro wasn't sleeping much, surviving only on tea and the sheer, unadulterated high of unrestricted engineering.
He had already done as he had promised, filing the provisional patents for SOW's Thermal Flow vents on day two, creating a labyrinth of defensive filings so complex that Marcos estimated it would take SIGS' legal team three years just to find the right jurisdiction to sue in if they could even get anyone to believe that they truly had been working on a groundbreaking technology that outperfomed the shit out of what they had just thrown a major celebration for a 0.3% improvement.
With the legal shield in place, Kenjiro had thrown himself into the Hellfire capacitors project with a fervor that bordered on obsession.
"Marcos," Mark said, stretching his arms over his head. "Run it again. Slow motion. 10% speed at the moment of failure."
"Running simulation attempt number 147," Marcos chirped.
The hologram rebuilt itself. The red lines of the energy flow began to crawl through the system as Mark watched closely. He wasn't a theoretical physicist like Kenjiro, hell, he didn't even have any credentials. He was an alien's apprentice for a year and a half. He was a practical engineer, but he had been trained to have patience and continue analyzing things.
"There," Mark pointed a finger at the floating image.
At the junction where the input conduit met the capacitor bank, the energy flow didn't just enter as it was supposed to. Instead, it turbulated, swirling like water hitting a rock in a stream before forcing its way in. That microsecond of turbulence created a heat spike that the dampeners couldn't catch in time.
"It's catching," Mark muttered. "It's snagging on something right at the door."
Kenjiro stopped pacing and leaned in, squinting. "That's the transition point between the durasteel conduit and the crystalline ceramic of the capacitor. It should be seamless."
"It should be," Mark agreed. "But the sim thinks it's hitting a wall. Check the material alignment of the ceramic."
Kenjiro tapped the console, expanding the view down to the molecular level. The ceramic structure was a beautiful, orderly grid of synthetic diamond and superconductive alloy. "It's standard alignment. Vertical grain to maximize heat transfer up and out toward the vents."
Mark frowned. He stood up and walked over to the diagram. "Vertical grain? Like wood?"
"Wood?" Kenjiro raised an eyebrow at Mark before shrugging. "I guess you can say it is... in a sense. The crystalline structure allows electrons to flow easiest along the grain."
"Kenji," Mark looked at him. "The power isn't flowing up. It's flowing in a horizontal direction."
Kenjiro blinked. He looked at the diagram. He looked at Mark. He looked back at the diagram.
"The grain is perpendicular to the electron flow," Kenjiro whispered. "We aligned it for heat dissipation, not for conductivity. The electrons are smashing into the 'side' of the crystal lattice before they can enter the storage matrix, creating resistance at the molecular level."
"Like trying to push water through a screen door sideways," Mark nodded.
"But if we rotate the grain..." Kenjiro's fingers flew across the interface. "If we rotate it 90 degrees to align with the input flow, we lose 15% of the passive vertical heat dissipation."
"I don't think we really need passive dissipation," Mark countered. "We already have the Thermal Flow Vents. We have the fractal cooling loops. Just let the vents do the work. Align the material for the power."
Kenjiro nodded slowly and began typing. "Rotating the grain structure 90 degrees. Re-calculating resistance coefficient... my god. Resistance drops by 80%. But the thermal load on the vents will spike."
"It may not be the perfect solution, but I'm sure my vents can take it," Mark said with a grin. "Let's run it."
Kenjiro hit the button. "Simulation number 148."
The hologram flared to life. The energy poured from the reactor and made its way to the junction. This time around, there was no turbulence. The red line shot straight into the capacitor bank. The bank glowed, the color shifted from red to a stable white, and the energy held. Then the tri-phase loop engaged, cycling the power smoothly.
The simulation ran for 1 second... 5 seconds... 10 seconds... 30 seconds.
"Huh, would you look at that. It seems like you boys managed to get this thing to stabilize," Marcos said, his voice sounding genuinely impressed. "Capacitor charge at 100%. The thermal output is managing at 92% capacity of the cooling system, and the containment seems to be holding."
The room was silent for a while, save for the hum of the cooling fans in the terminal.
Kenjiro stared at the glowing white orb in the center of the table, his mouth hanging slightly open. He looked like he was witnessing a miracle.
"It... it works," Kenjiro breathed.
Mark let out a laugh and reached over, slapping Kenjiro on the back, nearly sending the smaller man flying into the wall.
"Hell yeah!" Mark celebrated. "We did it! We fucking did it!"
Kenjiro stumbled, righted himself, and then started laughing too. "It was the grain alignment! A simple geometric rotation! We spent three days redesigning the containment field, and it was just the damn grain alignment!"
"Sometimes you gotta look at the wood, not the tree," Mark said, not caring if he was butchering the metaphor.
Then the office door slid open, and in walked Lyra. "Papa?"
Mark spun around. Lyra stood in the doorway, clutching her backpack straps. She had just been dropped off from the orphanage by the private security service Mark had hired (a luxury afforded by his recent windfall with the Void Vanguards and the vents sale, which had gained even more traction after patenting the technology). She looked at the two men, one giant, one not so giant, both grinning like maniacs, and then at the glowing white hologram.
"Is it gonna go boom again?" she asked, eyeing the projection warily. She had been present for Simulation 142, which had resulted in a spectacular, albeit virtual, explosion that had startled her into dropping the G-comm Mark had bought her.
"No boom, bug," Mark said, crossing the room in two strides to scoop her up. He lifted her high into the air, making her squeal with delight, before settling her on his hip. "No boom. We fixed it. Uncle Kenji fixed it."
"Uncle Kenji?" Takagi blinked, looking up. A strange flush colored his cheeks. He hadn't known Mark for more than a few days, so he wasn't expecting any titles of affection. Not to mention, he and Mark weren't really friends. "I... well, Mark identified the structural anomaly. It was a collaborative effort."
Lyra looked at Kenjiro. "Did you make the angry light go away?"
Kenjiro walked over to the terminal. He tapped a key, and the blinding white light of the hologram dimmed to a soft, pulsing blue, the color of stable energy.
"Yes, Lyra," Kenjiro said softly, smiling at her. "We made the light happy. Now it's going to help the ships fly very fast and shoot very far."
"Cool," Lyra decided. She then wiggled in Mark's arms, demanding to be put down. Mark set her on the floor, and she immediately ran to her corner of the office, where she had set up a 'fort' made of empty vent shipping crates. "Can I use my G-comm?"
"Go for it," Mark said.
He turned back to Kenjiro. The celebration was over; now the real work began.
"Send the files to the fabricator," Mark ordered. "Let's print this thing."
Kenjiro worked on compiling the data package, the fractal lattice vents, the new Hellfire capacitor specs with the rotated grain structure, and the custom mounting brackets Mark had designed.
"Sending them to the fabricators right now," Kenjiro said. "Mark, the tolerances on this are... extreme. We're talking atomic-level precision for the grain rotation. The standard industrial printers SIGS uses, even the high-end ones on Elyse, would have a 5% margin of error on a grain rotation this specific. That 5% error would cause a micro-fracture under load."
"I know," Mark said, walking toward the door that led to the hangar bay. "Come on. You haven't seen the triplets work yet."
They walked out onto the gantry of Berth 1. Below them, the skeletal remains of Vanguard-One sat in the anti-gravity clamps. But they headed to the side of the bay, where Mark had made an addition to the bay in the form of a massive room. Inside it, the massive fabrication units sat.
They were just like the boxy, clumsy printers Kenjiro was used to. Only one of them was printing, but contrary to what Kenjiro expected, this nanoprinter wasn't spraying molten alloy into a cast. It was weaving.
Kenjiro pressed his face to the glass. "What... what method is this? It's not standard sintering. It looks like... vapor deposition? But it's too fast."
Inside the chamber, the capacitor bank was already emerging. Since it wasn't too big, it was printing the entire thing altogether; its material was being fused atom by atom, the grain structure being dictated in real-time by the electromagnetic fields guiding the dust.
"It's molecular assembly," Mark said casually, leaning on the railing next to him. "Nanoparticle fusion. It doesn't melt the material into a specific thing. Rather, it bonds it at the atomic level using a harmonic resonance field with no heat stress, impurities, and with perfect alignment."
Kenjiro turned to look at Mark, his eyes wide. "Mark... this technology is something else... SIGS has theoretical papers on this, claiming it's at least twenty years away. The power requirements alone for the resonance field would require a dedicated fusion plant. But this isn't even like the theoretical papers I've read. This is far more advanced!"
"The Shepherd has a really good reactor," Mark shrugged. "And Anahrin knew his stuff."
"Anahrin?" Kenjiro asked, tilting his head.
"Long story. An old friend," Mark said, his tone indicating the topic was closed. "The point is, the print will be done in about half an hour. Perfect grain, with zero defects, and probably stronger than anything SIGS has ever put on a ship."
Kenjiro looked back at the printer. He watched the Hellfire capacitor taking shape, a dark, dense block of potential energy that had the potential of revolutionizing weapons.
"I spent ten years trying to get a nozzle to spray titanium 2% faster," Kenjiro whispered. "And you have a machine that knits diamonds."
"It could definitely do better than diamonds," Mark corrected. "And now, we have another engineer to play with it."
Kenjiro looked at the giant of a man. He felt small, physically, but for the first time in his life, he felt giant professionally. He wasn't just a cog. He was part of the machine.
"Okay," Kenjiro said, his voice firming up. "If the print finishes in four hours, I need to modify the reactor interface on the Vanguard-One. The new capacitors are going to demand a thicker bus cable. I'll need to strip the secondary couplings."
"You do the reactor," Mark said, cracking his knuckles. "I'm going to start on the fun part."
"The fun part?" Kenjiro asked.
"The guns," Mark grinned. "Vorn wanted autocannons. Well, I'm going to give him something better."

One Week Later

POV: Mark Shephard
"Hold the light steady, Marcos," I said.
"I am a collection of algorithms distributed across a subspace network, Mark. I do not have hands. The drone is holding the light," Marcos retorted in my ear.
"Well, tell the drone to hold it steady," I said again. "It's vibrating."
"The drone is vibrating because you are currently hammering a Class-5 mount into a Class-3 bulkhead," Marcos stated in a deadpan tone. "The structural reverberations are significant. Why don't you just use that fancy pendant with that being trapped in it and, oh, I don't know, turn it into a suit with lights for you to see?"
"It'll fit," I grunted, ignoring the latter part of what he said while swinging the heavy hydraulic mallet one more time.
CLANG.
The mount seated with a groan of protesting metal.
"See? Fits," I said while wiping the sweat from my eyes and stepping back to admire the work.
I was deep inside the forward weapon sponson of Vanguard-One. The ship was a skeleton. Over the last week, we had stripped her down to her bones. The armor plating was gone, stacked in Berth 2. The old wiring harnesses had been ripped out, lying in piles on the dock floor. The cockpit canopy was removed, leaving the flight deck open to the air of the bay.
She looked like a wreck. But to me, she looked like a blank canvas. And right now, I was painting with high-velocity slugs.
Vorn had asked for upgrades to his forward batteries. Standard Valkyrie gunships carried dual 30mm rotary autocannons. They were good for strafing runs and dogfighting fighters and even the converted freighter with autocannons. But I wanted Vorn to hunt. I wanted him to hurt things bigger than him.
So, I had decided to do something a little... excessive.
I climbed out of the sponson and dropped down to the bay deck, landing with a heavy thud. I walked over to the workbench where the new weapons sat.
They were beautiful.
I had taken the schematic for the Shepherd's main railguns, and I had scaled them down. I shortened the barrel length to 9 meters, tightened the magnetic coil spacing, and removed the independent turret traverse gears to make them fixed-mount weapons.
The result was the SOW-RG1, which I took to naming the "Needler." Yeah, Kenji would have to create another patent for this. It was sleek, dark, and menacing. Four of them lay on the ground ready to be moved.
"Kenji!" I yelled out, my voice echoing in the cavernous bay.
"Yo!" Kenjiro's voice drifted down from the open cockpit of the Vanguard. He popped his head out, his gray jumpsuit now permanently stained with grease and hydraulic fluid. He had a pair of magn-goggles pushed up on his forehead and a smudge of carbon on his nose. He looked like a raccoon that had discovered physics.
"How's the bus bar coming along?" I asked.
"It's done!" he shouted back. "I routed the tri-phase cables through the dorsal spine. We have a direct line from the reactor to the capacitor bays, and the resistance is negligible. I'm just flashing the firmware on the power management node now. Did you finish the mounts?"
"Mounts are seated," I said. "I'm ready to hoist the guns."
Kenjiro scrambled down the ladder. He moved with a lot more confidence now than he had a week ago, when I had thrust him into getting his hands dirty. This wasn't even his field of expertise, and that was something he tried to argue. But I eventually convinced him that he needed to get his hands dirty every once in a while, and that following a simple set of instructions wasn't that hard. And would you look at him now! He wasn't afraid of the ship anymore.
He walked over to the bench and ran a hand along the barrel of one of the Needlers.
"These are absurd, Mark," he said, shaking his head, though he was smiling. "You're putting frigate-class weaponry on what is pretty much a fat fighter. The recoil alone should tear the frame apart."
"That's why I reinforced the frame with a hexagonal weave," I reminded him. "And the recoil dampeners are integrated into the magnetic rails. It won't kick back. It'll just push the ship backward a little bit."
"A little bit," Kenjiro chuckled. "Mark, the effective range on these is what? Thirty thousand kilometers?"
"Sixty to seventy, depending on the ammo type," I said proudly. "Standard tungsten penetrators will give you sixty. If they shell out for the depleted uranium slivers, they can touch someone at seventy-five."
"A Valkyrie's sensor package only reaches forty thousand kilometers," Kenjiro pointed out. "They literally can't see what they're shooting at."
"That's why I'm ripping out the sensor package next," I grinned. "But first, let's get these bad boys hung."
We spent the next three hours wrestling the railguns into place. It was heavy, precise work. Even with the gravity hoists, the drones, and my strength, lining up the power couplings required finesse, a whole lot more finesse than I anticipated.
"Left... a little left... okay, hold it," Kenjiro guided the hoist while the drones and I maneuvered the thirteen-ton weapon into the sponson.
"Aligning the locking pins," I grunted, bracing my shoulder against the receiver. "Marcos, engage the mag-locks on my mark. Three... two... one... now."
THUNK.
The railgun locked into the chassis, and the ship groaned, accepting the new weight.
We repeated the process three more times, and by the time we were done, the Vanguard-One looked radically different. Instead of the stubby, bulbous noses of the autocannons, she now sported four long, but skinny barrels that protruded from the forward fuselage like the fangs of a deep-sea predator.
I stepped back, wiping my hands on a rag. "Now that is a gunship."
"Now, that's a railgun with engines," Kenjiro corrected, handing me a bottle of Rec-H2O, or recycled water with a fancy name. "I never met this Vorn you speak of, but then again, I never really had any personal interactions with the Void Vanguard. My guess is he's going to lose his mind."
"Speaking of Vorn," Marcos chimed in over the PA system. "We have an incoming transmission from the Void Vanguard. Just a status check and another portion of the payment to the tune of 1.8 million credits. Also, we may have a potential new client with pockets far deeper than the Void Vanguard."
"Good. Tell Vorn we're on schedule," I said. "And tell him to start sourcing tungsten ammo. Lots of it."
"Will do," Marcos confirmed. "Don't you want to know who this new client may be?"
I took a long drink of water, looking at the stripped hull. "No, not right now. We'll get to it later. If the job is something we can do, then accept it."
"Are you sure you don't want to know?" Marcos asked.
"Positive," I said.
I rested for a little while longer before getting ready to do the part that I had been so thankful Anahrin had done with the Shepherd.
"Alright, Kenji," I sighed, tossing the rag onto the bench. "The heavy lifting is done. Now we have to wire this shit."
Kenjiro looked at the exposed belly of the ship, where thousands of meters of optical cabling and power conduits needed to be run.
"This will be done mostly by the drones, right?" He asked.
"Nope," I shook my head.
"Alright. I'll take the port side then," Kenjiro sighed. "I want to monitor the capacitor integration personally."
"I have no problems with that. I'll take the starboard and the cockpit avionics," I said. "We need to tie the new fire control system into the pilot's HUD. If they're going to shoot at seventy klicks, they need a targeting computer that can calculate orbital mechanics."
We climbed back into the ship and, for the rest of the day, it was just the two of us, working in the cramped confines of the fuselage. It was quiet, mostly. The only sounds were the snip of wire cutters, the hum of the soldering lasers, and the occasional grunt of exertion.
But it was a comfortable silence. The kind you share with someone who knows what they're doing.
"Hey, Mark?" Kenjiro's voice echoed from the port crawlspace.
"Yeah?" I was upside down under the cockpit console, splicing a sensor feed.
"I checked the news feed from Elyse today," he said.
"Yeah? Did the sun fail to bloom?" I asked?
"No. But SIGS stock took a hit," Kenjiro stated. "I saw they were down four points. Rumor is their lead thermal engineer for the Novellus system vanished, and investors are jittery."
I paused, holding the soldering iron steady. "You regret it?"
There was a pause. I could hear Kenjiro shifting in the crawlspace.
"I'm currently covered in grease," Kenjiro said. "My back hurts. I'm eating pizza for the sixth day in a row. And I'm installing a weapon that is technically illegal onto a mercenary gunship."
"That sounds like a yes," I stated.
"No," Kenjiro said, and I could hear the smile in his voice. "It's quite the opposite. I've never been happier. The Mark IV vent... the one I got the award for? I spent six months in meetings just to get approval to change the screw size. But here? With you? We redesigned the entire power grid of a starship in a week."
"We move fast," I agreed, finishing the splice.
"No, we move dangerously," Kenjiro corrected. "But God, it feels good."
"Just wait until we turn it on," I said, pulling myself out from under the console. "When you hear those capacitors sing and you feel those rails thunder... that's the real drug, Kenji. Watching something you built come alive."
I climbed out of the cockpit and looked at the ship. It was a mess of wires and exposed metal right now.
"Marcos," I said. "Play something good."
"Music, I presume?" Marcos's voice echoed throughout the bay. "How about some Classic Rock?"
"You know me so well," I said.
"It truly is some good music. Playing 'Fortunate Son'," Marcos replied.
The opening guitar riff blasted through the bay's speakers.
I saw Kenjiro pop his head out of the crawlspace he was in. "What is this?"
"This," I said, picking up a spool of heavy-gauge power cable, "is working music. Let's get this bird wired."
As the drums kicked in, I saw Kenjiro bobbing his head as he dove back into the crawlspace.
We had a long night ahead of us. The Vanguard-One was currently just a skeleton with big guns. But in a few days, she was going to be the new gunship in the park, the most dangerous gunship in the park. And the best part of it all was, she was just the prototype. A preview of what I plan to create in the future.
