Flagship (A Captain's Crucible #1) (8 page)

Jonathan tapped his chin with his usual triangular arrangement of fingers. "Have every capable vessel in the task unit launch four kinetic kill missiles each at the target," Jonathan said. "Space out the launch so that the missiles arrive in ten second intervals. I want the projectiles to approach on different vectors, too, if possible. Let's see if we can sneak one in while their particle beam is recharging. Fire when ready."

"Firing," Miko said a moment later.

Jonathan studied the display. He watched the first wave of missiles, represented as four green dots, spread out behind the task unit. Three more waves followed, separated by a distance of about ten kilometers each. The waves approached the target, traveling diagonally down the Z and Y planes. The missile course changes came slower than normal, thanks to the massive Delta V's required near the gas giant.

Several minutes later the first wave closed to within ten thousand kilometers of the target.

"Let's see what kind of point defenses they have," Jonathan said.

"Target is adjusting its trajectory," McNamara said. "Looks like it's going to try flying right past the missiles."

Jonathan studied the display. The dotted line representing the target's path updated. According to the estimated trajectory, it would avoid the first two waves entirely, but the third and fourth would impact.

The minutes ticked past. As expected, the first two waves missed by two kilometers each. The third and fourth however directly lined up with the ship.

"Detecting a thermal buildup in the nose of the target," McNamara said. There was a flash, followed by eight simultaneous, smaller lights. "All eight kinetic kill missiles have detonated. Target is issuing a slight course correction to avoid the debris."

The enemy was now twenty thousand kilometers behind the task unit, with the trailing
Grimm
the closest to it.

"What about another Viper broadside?" Jonathan said. "We're at one hundred percent charge."

"We are," Miko agreed. "But the spot area at this range is over eighty centimeters squared. Even combined with the other ships, the intensity will be less than three megajoules."

"Let them close and then fire?" Robert asked Jonathan.

"I'm not big on any plan that allows them to close," Jonathan said. "We've already seen how deadly that particle beam is under five thousand kilometers." He studied the 3D display a moment longer. "Tactical, have the
Aurelia
,
Maelstrom
and
Selene
alter course ten degrees to the starboard, and the
Grimm
ten to port. Helm, match the course of the
Callaway
to the
Grimm
."

"I thought you didn't like splitting up the task unit?" Robert said.

"I don't," Jonathan answered.

He watched on the 3D display as the
Callaway
and
Grimm
separated from the other two ships.

"Enemy vessel is adjusting course," the ensign announced.

The dotted line of the pursuer moved to intercept the lagging
Grimm
. The enemy smelled easy prey, apparently. The harvester vessel lay approximately a thousand kilometers off the
Callaway's
aft quarter, in the eight o'clock position, thirty degrees declination. And it was moving farther away by the moment.

"What are you planning, Captain?" Robert said.

"I'm taking us closer to Achilles," Jonathan said.

Jonathan concentrated on the display.

Robert extended his noise canceler around the captain.

"Are you sure the
Callaway
can withstand the stress?" Robert said. "She doesn't have the armor of the
Grimm
."

"I only plan to skim the upper atmosphere," Jonathan said. "Like skipping a stone on a river."

"That's a fairly big river," Robert said, his usual positivity nowhere to be found.

"The
Callaway
will hold up. Right, Maxwell?"

"There is a seventy-five percent chance the
Callaway
will survive such close proximity to the gas giant," Maxwell said.

"There you go," Jonathan told Robert.

The commander didn't seem pleased. "Seventy-five percent. Those aren't the best odds. Even at ninety-nine percent, I wouldn't feel safe."

"Very few things in life are seventy-five percent, Robert. Let alone ninety-nine."

Robert squeezed his jaw. "If we break up... we won't be able to launch escape pods. Not this close to the giant. You know that, right?"

"I do." Jonathan repealed Robert's noise canceling. "Helm, take us in closer to the giant."

The helmsman hesitated.

"Helm?" Jonathan repeated.

"Taking us closer. Initiating braking maneuver."

The best way to enter a massive gravity well like a gas giant was by "falling" in. To do that, one simply decelerated, forcing the orbit to rapidly decay.

"Tactical, instruct the
Grimm
to follow us down."

The tense minutes passed, with the
Callaway
growing ever closer to the colorful mass of clouds below.

"Hull temperature is rising," Ensign McNamara said. "Currently six hundred degrees Kelvin. Heat armor is holding."

Behind them, the pursuing vessel decelerated, too, choosing to stay with the pair. The target was fifteen thousand kilometers away.

"Entering upper thermosphere," Ensign McNamara said. "Hull temperature stabilizing at one thousand Kelvin."

"Hold her steady..." Jonathan said.

A few minutes later:

"Hull temperature has dropped to four hundred Kelvin." McNamara said. That was the peculiar nature of Jovian-type gas giants—the radiated heat peaked roughly a thousand kilometers from the surface, then decreased to the tropopause, where it would begin rising again.

"Approaching Kármán line of lower thermosphere," Miko said. That was the point at which atmospheric reentry began, about four hundred kilometers above the cloud coverage.

"Nose up," Jonathan said. "Helm, bounce us off the lower thermosphere. Start the long process of disengaging from the gravity well. Tactical, instruct the
Grimm
to do likewise."

"Nose up," the helmsman said. "Initiating deorbital pre-burn sequence."

The bridge began to shake badly as the
Callaway's
hull struggled against the stresses exerted upon the ship—inertia wanted to carry her forward, the thrusters wanted to push her away, the gas giant wanted to draw her in; all of these forces vying against one another literally threatened to rip the
Callaway
apart.

A call from engineering flashed urgently in the lower left of Jonathan's HUD.

The captain answered it reluctantly.

"What in the hell are you doing?" Stanley said over the comm. "You're going to tear my ship apart!"

"She'll hold together, Stan. And if you wouldn't mind, we're in the middle of a battle here. Don't call again unless you have something urgent to report. Do your best to keep our reactors running. Now would not be a good time for the engines to fail."

Jonathan disconnected before the chief engineer could answer.

He gazed at the tactical display. The
Callaway
and
Grimm
moved away from the gas giant very sluggishly. It was small consolation that the enemy ship's own course changes were just as lethargic. The target was still gaining, however.

Jonathan pulled up the propellant indicator on his HUD. The inert gas levels were dropping incredibly fast thanks to the immense Delta V costs—the tanks would have enough to escape the gravity well, though just barely. When the battle was done he would have to transfer some propellant away from the other ships to restore the
Callaway
to baseline levels.

Jonathan and the others were jerked in their seats as the inertial compensators struggled against a sudden reversal of Gs.

"We just bounced off the Kármán line," the helmsman informed him.

"Steady as she goes..." Jonathan glanced at the 3D display. The
Grimm
was fifteen hundred kilometers behind them. Twelve thousand kilometers beyond it lay the alien vessel. Too close for comfort.

But close enough for what he planned.

"Tactical, work with Maxwell," Jonathan said. "I want you to launch fifteen mortars from the aft tubes at the enemy ship. Hem them in with the first ten. I want the final five directed at the lower thermosphere. Make them think we miscalculated. But in reality, I want you to skim those final five off the Kármán line. Time it so that the deflection happens as close to the target as possible. Catch them by surprise."

Kinetic kill missiles or even nukes would have worked just as well, but that close to the gas giant, missiles behaved the same as the unpowered mortars, which were basically big rocks.

"It's going to be tricky," Miko said. "We'll have to orient the launch tubes so that the mortars arrive at the Kármán Line at the precise angle for optimal deflection. And time that deflection so that at least one of the mortars actually strikes the ship."

"Like I said, work with Maxwell."

The moments ticked past. Jonathan watched the enemy vessel close to nine thousand kilometers.

"Hull temperature rising again," McNamara said.

Growing impatient, Jonathan said: "Miko, do you have a firing solution?"

Miko didn't answer.

"Tactical, do you have a firing solution?" Jonathan repeated.

"I think so," Miko said.

"Fire."

Fifteen mortars released in rapid succession from the aft tubes. On the tactical display, the first ten formed a circular noose around the enemy ship. The final five seemed to be misses, heading at a downward angle as if to pass underneath the target.

On the tactical display, three of the five bottommost mortars passed through the indicated Kármán Line, their orientations off by just enough to make the skimming process fail. They would burn up shortly.

However two of the mortars abruptly changed course, deflecting upward from the Kármán Line and toward the target.

"Like skipping stones on a river," Jonathan said softly.

"Enemy ship is issuing sudden braking thrust," Ensign McNamara said.

"Too late," Jonathan said.

"They're firing their particle beam."

Jonathan waited. The shaking of the bridge didn't seem any worse.

"Damage report?" he said after a moment.

"According to my readings," McNamara said. "The beam only lasted a tenth of its usual duration. They struck the
Grimm's
aft section
.
Her captain is reporting minimal damage."

"That beam of theirs obeys the inverse square law," Robert said. Meaning the intensity dropped by the square of the distance to the source.

"If it's a particle beam, it has to," Jonathan said. "The extra armor on the
Grimm
probably helped. Plus the fact that it only fired for a tenth of its usual duration. Ensign, tell me our mortars struck."

"Both struck," McNamara said.

Jonathan clasped his right hand into a triumphant fist. "Status on the target?"

"They appear to have taken major damage to the nose section. I believe their particle weapon is nonoperational. And their engines have cut out entirely. The vessel is on a decaying orbit; at their current rate of descent, it will be about four weeks before they penetrate the Kármán line, and if they survive reentry, another two months before they breach the cloud cover. Maybe another six months after that before the vessel is crushed by the pressure."

"Achilles heel," Jonathan said.

On the external video feed, he zoomed in on the target. He switched to LIDAR. The damage to the vessel was incredible. According to the display, a gaping wound two hundred meters deep and ten meters wide was carved into the ship from the nose down.

He glanced at the comm officer. "Signal for their surrender. And extend an invitation of aid."

"No response," the lieutenant said.

"Not surprising." Robert said. "They can't understand us, of course."

Jonathan smiled sadly. "We had to try."

"Sir, their speed is dramatically dropping off." McNamara said.

"What?" Jonathan said. "I thought their engines had cut out?"

"They had... but it looks like they reactivated them. They appear to be applying reverse thrust. They're purposely decaying their orbit."

"Why hasten their demise? You said it would be four weeks before they even reached the Kármán line. That's enough time to at least attempt a repair."

"But they know they'd be at our mercy the whole time," Miko said. "Maybe, to them, this was the only honorable choice."

Jonathan regarded the tactical officer appraisingly. "I get the feeling you come from a Japanese background."

Miko managed a weak smile. "My distant ancestors were samurai."

Jonathan switched his gaze to the helmsman. "Get us out of here."
