Iron and Rust

Mara Solis had been awake for nineteen hours when the number three coolant pump on the Draga decided to seize.

She heard it before the diagnostic flagged it. A change in pitch from the engine room below, the kind of sound that doesn't register on most people but hits an engineer like a wrong note in a song you've heard a thousand times. She put down her coffee, which had gone cold an hour ago, and pulled up the thermal readout on the maintenance console. The pump's temperature curve was climbing in that lazy, patient way that meant the bearings were going.

"Reyes," she said into the comms. "Number three coolant on the port drive. Bearings."

A pause. Then: "We don't have replacement bearings for a K-series pump."

"I know."

"The Vostok had K-series pumps. Before they scrapped her."

"I know that too. Check Bay Four. Vasquez pulled parts off the Vostok last month. There should be a crate somewhere near the aft wall."

She listened to Reyes move through the lower deck, boots on grated metal, the echo of it traveling up through the hull like the ship was sighing. The Draga was fifty-two years old. She'd been a bulk ore hauler working the asteroid fields around Barnard's Star when the League was still a collection of mining charters and angry letters to the Federation trade office. Someone had welded gun mounts to her upper deck in '39, bolted on a military sensor suite that was already outdated when they bought it, and called her a patrol frigate. The designation was generous. What the Draga actually was, was a ship that refused to stop working.

Mara had been her chief engineer for three years. Before that, she'd spent eight years on the Kowalski, a refinery tender that had been converted to a frigate and then back to a tender when the conversion proved too expensive to maintain. Before the Kowalski, she'd worked on a mining platform near Luyten's Star, pulling eighteen-hour shifts in low gravity until her knees started giving her trouble. She was forty-one. She felt older on bad days, which were most days lately.

The League didn't build warships. That was the Federation's job, and the NEC's, and whatever the Compact was calling themselves these days. The League built working ships and then, when the situation demanded it, made them fight. The difference mattered. A purpose-built warship had clean lines, redundant systems designed to fail gracefully, compartments that sealed automatically when the hull was breached. A converted ore hauler had whatever you bolted onto it and the structural integrity that came from being overbuilt in the first place. ORI ships survived because they were designed to carry a hundred thousand tons of raw material through asteroid fields. War was, in some respects, gentler than that.

Reyes came back on comms. "Found the crate. Bearings look good. Forty minutes to swap?"

"Thirty if you don't strip the threads this time."

"That was one time, Solis."

"It was twice, and the second time I had to re-tap the housing by hand because we didn't have the right die set."

She could hear him grinning through the static. That was the thing about League crews. You worked with the same people long enough, you didn't need to see their faces to know what they were doing with them.

The Draga was docked at Ferris Platform, a League maintenance facility that occupied the core of a captured asteroid in the Barnard Corridor. Calling it a maintenance facility was another act of generosity. It was a pressurized cavern with magnetic clamps on the walls, a machine shop that had been assembled from salvaged equipment, and a quartermaster who could find you a replacement part for anything as long as you didn't ask where it came from. Six other ships were docked alongside the Draga, hanging in the low gravity like sleeping animals. The Tolstoy, the Gradnik, the Mesa Verde, and three others whose names Mara could never remember because they'd been renamed too many times.

All of them were old. All of them were being prepared for the same thing.

Director Kessler had called it a "resource security operation," which was League management speak for moving into a Gravity Well that someone else thought they owned. The target was a dense asteroid field two Gravity Wells over, rich in the kind of heavy metals that the core systems paid premium rates for. A Federation survey team had flagged it three weeks ago. A NEC monitoring station had been tracking the gravitational data for months. The League intended to get there first, or at least to get there with enough ships that being second wouldn't matter.

Mara didn't think about the politics of it. She thought about coolant pumps, about hull stress tolerances, about whether the Draga's port drive would hold through a Jump and the stabilization burn on the other side. The Jump Drive drew enormous power during charge-up, and every system on the ship felt it. Lights dimmed. Displays flickered. The hull groaned in a way that the manual said was normal thermal expansion but that Mara suspected was something less understood and considerably more unsettling.

She pulled up the Draga's maintenance log on her tablet. The file was enormous, stretching back decades, a history of the ship written in part numbers and labor hours. Every engineer who had ever worked on her had left something behind in that log. Notes in the margins, warnings about specific components, the occasional frustrated comment about the quality of replacement parts from particular suppliers. Mara had added her own over the years. She knew this ship the way a doctor knows a long-term patient, every scar and every weakness.

The port drive had been rebuilt in '41 after something near Barnard's that the log described only as "catastrophic thermal event." The starboard drive was newer, pulled from a decommissioned tug in '45. Each engine was its own system with its own power feed. Lose one in a fight and the Draga would slow to a crawl, but she'd keep moving. The hull plating had been reinforced twice, the second time with armor-grade composite that someone had acquired through channels that the log politely declined to detail. The shield generators were League surplus, medium-class, slow on the regen but capable of absorbing hits that would have overwhelmed a lighter ship's capacitors. The sensor array had been upgraded last year, though "upgraded" meant replacing a fifteen-year-old unit with a ten-year-old one. If someone put a round through it, the Draga's weapons would lose half their effective range and she'd be fighting what she couldn't properly see.

None of it was elegant. All of it worked.

"Bearings are in," Reyes said. "Spinning up number three."

Mara watched the temperature curve on her console. It flattened, settled, found its rhythm. The pitch from the engine room below shifted back to where it should be.

"Reads clean," she said. "Good work."

She picked up her coffee, remembered it was cold, drank it anyway. In twelve hours, the Draga would power up her Jump Drive and transit to the target Gravity Well with the rest of the task force. There would be Federation ships there, probably. Maybe NEC pickets on the edges. The Draga's laser turrets were old, her ion cannon wheezed during test fires, her shield generators were slow, and her engines would lose a race against anything built in the last twenty years.

But her hull was thick, her reactor was steady, and her coolant pumps were running clean.

Mara closed the maintenance log and started on the next item on her list. There were always more items on the list.
