The Shipyard Walks

The thing about the Anvil is that you can walk for twenty minutes in a straight line and still be inside her.

Davi Okonkwo knew this because he timed it once, on his third week aboard, when the route from his bunk in Section C to the fabrication bay on the forward spine took him through four pressure doors, two cargo lifts, and a stretch of corridor so long that the far end disappeared into the slight curve of the hull. Twenty-two minutes, to be exact, and that was at a pace that his supervisor would have called "hustling." The Anvil was not a ship you crossed casually.

She was a Mobile Shipyard, one of eleven currently operating on the Outer Line. The Federation had sent three. The League had four, two of which had been converted from orbital drydock platforms. The Compact had deployed two, newer and sleeker than anyone else's. The remaining pair belonged to independent operators who had sold their services to the highest bidder before the bidding turned into something closer to conscription. Davi worked for the League. The Anvil was the oldest Mobile Shipyard in the cluster, built at the Orion Forge twenty-six years ago for deep-space mining support. Like most things the League operated, she had been repurposed so many times that her original blueprints bore almost no resemblance to what she had become.

What she had become was a factory that could fly.

The fabrication bay ran along the ship's forward spine for nearly three hundred meters. Raw materials came in from the Supply Nodes through the aft cargo system, got processed in the refinement section amidships, and arrived at the fab bay as standardized material stock ready to be shaped into hull plating, drive components, weapon housings, sensor arrays. The bay could produce a destroyer from raw supply in about nine hours. A frigate took five. Davi had watched the process dozens of times and it still amazed him, the way the robotic arms moved in their choreographed sequences, laying down hull sections with a precision that the human welders on the finishing crew couldn't match and didn't try to.

His job was modules. The Anvil carried eighteen module bays distributed across her main sections, and Davi's team was responsible for installation, maintenance, and the occasional emergency reconfiguration that happened when the admiral decided mid-operation that the fleet needed more firepower and less logistics support. Each module was roughly the size of a small apartment and contained systems complex enough that Davi had spent his first six months aboard just learning the diagnostic protocols. Shield harmonics modules, weapons calibration systems, advanced targeting arrays, production accelerators. The modules shaped what the Anvil could do and, by extension, what the entire task force was capable of.

Today, the Anvil was jumping.

The announcement had come ninety minutes ago, the familiar three-tone chime followed by the operations officer's voice: "All hands, Jump transit in ninety minutes. Secure stations and non-essential systems. This is not a drill." The last part was a formality. On the Outer Line, it was never a drill.

Davi was in Module Bay Seven, running the pre-Jump diagnostic on a shield harmonics unit that had been giving inconsistent readings for the past two days. The Jump Drive on a ship the size of the Anvil drew power from every system aboard during charge-up. Lights dimmed. The air recyclers slowed to a crawl that you could feel in your lungs if you were paying attention. Non-critical displays went dark. And every module, every fabrication arm, every sensor array had to be powered down in sequence to feed the drive the energy it needed to fold space around six hundred thousand tons of metal and machinery.

"Forty-five minutes to charge-up initiation," the speakers announced.

Davi finished his diagnostic and sealed the module bay. The readings were still inconsistent, but they were within tolerance, and there was nothing he could do about it in forty-five minutes that he hadn't already tried in two days. He walked aft through the central corridor toward the crew section, passing the open blast doors of Fabrication Bay Two. Inside, the robotic arms hung motionless in their cradles, powered down for the Jump. A half-finished frigate sat in the assembly frame, its port hull section exposed and unfinished, the internal wiring visible like veins under translucent skin. It would be completed on the other side.

The corridor was busier than usual. Jump transit made people restless. Engineers checking systems they'd already checked, techs securing equipment that was already secured, crew members finding reasons to move through the ship because sitting still while the Anvil prepared to bend physics felt wrong on some animal level that no amount of training could override.

He passed the mess hall on Deck Four. Someone had left the coffee station running, and the smell of it filled the corridor with something warm and ordinary. Two fabrication techs were sitting at a corner table, not talking, just sitting with their hands wrapped around their cups. Davi recognized one of them, Kessler, from the night shift. She looked tired in a way that had nothing to do with hours.

He'd heard the briefing, or the version of it that filtered down to module technicians. The Anvil was relocating to an unclaimed Gravity Well because the current position was getting crowded. That was the official language. What Davi had gathered from the corridor talk was different: a Federation cruiser group had been detected two Gravity Wells out, moving in a pattern that looked less like patrol and more like survey. Mapping approaches. Counting nodes. The kind of thing you did before you moved into a place and started building. Command had decided that the Anvil was better positioned somewhere the Federation hadn't started measuring yet.

Nobody said the word "retreat." Nobody had to.

Through the viewport next to the mess hall entrance, the Gravity Well stretched out in the familiar pattern of asteroids and distant structures. Supply Nodes blinked their operational lights. A pair of frigates, freshly built in the Anvil's own bay three days ago, held station a few kilometers off the port bow. In twenty minutes, all of it would be gone, replaced by a different Gravity Well with different asteroids and different problems.

"Fifteen minutes to charge-up."

Davi reached his station in the module control room, a compartment roughly the size of a walk-in closet with six displays and a chair that had been ergonomically designed for someone with shorter legs than his. He pulled up the module status board. All eighteen bays reported ready. Green across the board, except for the shield harmonics in Bay Seven, which showed amber. Consistent with the inconsistent readings. He flagged it in the log and moved on.

The charge-up started as a feeling before it became a sound. A vibration that ran through the deck plates, up through Davi's boots and into his bones. The lights dimmed. His displays flickered once, twice, then stabilized at reduced brightness. Somewhere deep in the Anvil's core, the Jump Drive was pulling energy from every system aboard, building the field that would fold the space between here and there into something a six-hundred-thousand-ton shipyard could cross in an instant.

The sound came next. A low harmonic that wasn't quite a hum and wasn't quite a groan. The hull was resonating. The engineers said it was thermal expansion from the drive field. Davi had heard other explanations from people who were less certain and more honest.

His stomach dropped, or seemed to. The displays went white for a fraction of a second. Then the Gravity Well outside the viewport was different. New asteroids. A red dwarf star where there had been a yellow one. No Supply Nodes yet, no structures, no friendly frigates. Empty space around an unclaimed Gravity Well.

Stabilization hit like a slow wave. The Anvil's systems stayed offline, recalibrating. The navigation systems ran their post-Jump checks. Davi watched his module board as each bay came back online in sequence, the ambers turning green one by one. Bay Seven's shield harmonics came up last, reading the same inconsistent numbers as before.

The operations officer's voice came through the speakers. "Jump complete. All stations report status. Fabrication bay, you are cleared to resume production."

In the viewport, the new Gravity Well waited. Somewhere in the asteroid field, there would be rocks worth extracting, positions worth holding, space worth claiming. The Anvil would anchor herself here, extend her fabrication arms, and start building the fleet that would make this Gravity Well theirs.

Davi pulled up the work order for the frigate sitting half-finished in Bay Two. Port hull section, internal wiring, drive mount installation. Four hours of work, give or take. He logged into the system and started the fabrication sequence.

The Anvil had arrived. Now the real work began.
