Earth Strike

by Ian Douglas

  In principle, speed in combat was as important as it had ever been in the long-gone era of aerofighters and atmospheric dogfights in the skies above Earth. However, if your closing velocity was too high relative to your opponent, there simply wasn’t time to react, even with electronic senses and AI reaction times. The target was there and gone before you could do a thing about it.

  The universe had minutes earlier slipped back into its more usual, low-velocity appearance. Eta Boötis, the star, glared dead ahead, smaller than Sol seen from Earth, but a hair brighter. Other stars gleamed in constellations distorted to Earth-born eyes; Arcturus was a golden beacon high and to the left relative to Gray’s current attitude.

  Haris, the target planet, was a tiny crescent close by the star, 1.8 million kilometers distant, growing larger moment by moment.

  At Gray’s command, the Starfighter began rearranging itself once again, adopting standard combat configuration—a blade-lean crescent, slender black wings drooping to either side of the thicker central body, the crescent tips stretched forward as if to embrace the enemy. Sleek streamlining wasn’t as necessary at these velocities as it was when plowing through near-vacuum at near-c, but there was always the possibility in these sorts of engagements that a fight would drop into planetary atmosphere, and then streamlining was very necessary indeed.

  Minutes earlier, as he dropped past .5 c, Gray had released the dustcatcher, sending a microscopic speck of collected dust and hydrogen atoms compressed into a neutron micro-body hurtling ahead at half the sped of light. If it, by sheer, random chance, hit an enemy spacecraft as it zipped through the system, so much the better, but there was no way to aim it. Like the vaporized whiffs of any A7 strike packages that had missed their targets, the dust balls released by the infalling fighters would remain interstellar navigation hazards for eons to come.

  Data flooded across Gray’s navigational and combat displays. As he glanced this across the screen, his in-head display opened windows, showing magnified views.

  Expanding spheres of star-hot gas marked the funereal pyres of four Turusch ships, while a fifth tumbled end for end through space, spilling a haze of vaporized armor, internal atmosphere, and sparkling debris in its wake. Patches of bright-glowing turbulence on the planet’s night side showed where two A7s had missed orbital targets and struck the planet instead.

  So…five hits total. Not bad, considering the Kentucky windage involved from sixth tenths of an AU out. That left fifty enemy vessels to deal with…correction, fifty-three. Three others must have either been masked by the planet when America had first scanned the inner system, or had arrived in the objective hours since.

  Enemy warships were scattering from the vicinity of the planet, a swarm of nest-kicked hornets. Turusch vessels were characteristically large, bulky, and clumsy-looking, the space-going equivalents of fortresses painted in bold swaths of either green and black or a starker red and black. Even their fighters, painted in green-and-black stripes, had the look of lumpy potatoes, each four to five times the mass of a Confederation Starhawk.

  Despite appearances, they were fast and they were deadly. Gray caught one huge capital ship with his eyes and held it as he triggered a weapons lock. The Starhawk’s offensive warload consisted of thirty-two VG-10 Krait smart missiles, a StellarDyne Blue Lightning PBP-2 particle beam projector, and, for very close work, a Gatling RFK-90 KK cannon. At long range, smart missiles were always the weapon of choice.

  A tone sounded in his ear, indicating that a VG had acquired lock.

  “Omega Seven!” he called over the tacnet. “Target lock! Fox One!”

  The missile streaked from beneath the embrace of Gray’s wings, the heat dump from its miniature gravitic drive gleaming like a tiny sun as it streaked through space.

  The other Starhawks were all there, still in the circle formation they’d adopted out in the system’s Kuiper Belt. The circle was opening now as the fighters applied lateral thrust and spread themselves apart. Other pilots were calling Fox One now, the code-phrase that meant they were firing smart missiles. More missiles flashed into the gulf ahead, tracking and dogging enemy warships, each accelerating at close to one thousand gravities.

  His missile and two others were closing with the big green-and-black enemy warship—a Tango-class destroyer, under the standard Confederation nomenclature for enemy ships. The enemy was dumping sand—blasting clouds of tiny, refractive particles into space both to defeat laser targeting systems and to serve as a physical barrier against incoming kinetic-kill or high-velocity warheads.

  One missile hit the expanding sand cloud and exploded, a ten-kiloton blast that pulsed in the darkness, but the other two missiles plunged through the hole vaporized in the Turusch ship’s defensive barrier, striking its magnetic shielding and detonating like a close pair of bright, savage novae.

  Enemy shield technology was a bit better than the Confederation could manage yet. Neither nuke penetrated the envelope of twisted spacetime sheathing the destroyer, but enough of the double blast leaked through to crumple a portion of the warship’s aft hull. Atmosphere spilled into space as the ship slewed to one side, staggered by the hit.

  Gray was already tracking another Turusch warship, however, a more distant one, a Juliet-class cruiser accelerating hard toward the planet.

  “Omega Seven!” he called. “Target lock! Fox One…and Fox One!” Two Kraits streaked into darkness.

  “Incoming, everyone,” Allyn warned. “Jink and pull gee!”

  The half of the sky in the direction of planet and sun was filled now with red blips, the icons marking incoming enemy missiles. Turusch anti-ship missile technology was better than human systems, and their warshots packed bigger warheads.

  This, Gray thought, is where things get interesting.

  Throughout his gravfighter training back at SupraQuito, they’d hammered away at one essential lesson of space-fighter tactics: always, when an incoming warhead reached your position, be someplace else.

  Gray had been in combat twice before, at Arcturus Station against the Turusch and at Everdawn against the Chinese, and knew the truth of that statement. There was no effective way to jam incoming warheads. The missiles used by both sides were piloted by brilliant if somewhat narrow-minded AIs, using a variety of sensor systems to track and home on an enemy target. No one set of standard countermeasures could blind all of an enemy’s sensors—heat, radar, mass, gravitometric, X-ray, neutrino, optical.

  Nor was it possible to outrun them. Turusch anti-fighter missiles could accelerate faster than a Starhawk, at least for short bursts. They operated on the tactical assumption that if they couldn’t kill you outright, they could chase you out of town, forcing you into a straight-run boost out of battlespace to where you no longer posed a threat.

  So when enemy missiles were hunting you down, the ancient aphorism about a best defense was decidedly true. You dodged, you weaved, you accelerated…but you also struck back.

  A swarm of missiles approached from ahead, brilliant red pinpoints projected by the Starhawk’s display system against the stars. Gray’s AI picked out no fewer than six enemy missiles that, judging by their vectors, were homing in on him.

  “Here comes the reception committee,” Allyn announced. “Independent maneuvering.”

  “Copy that, Blue Omega Leader.”

  He accelerated toward the oncoming missiles, hard, then threw his Starhawk into a low-port turn, as tight as he could manage at this velocity.

  Vector changes in space-fighter combat were a lot trickier than for an atmospheric fighter; they were possible at all only because gravitic propulsive systems allowed the fighter to project a deep singularity above, below, or to one side or the other relative to the craft’s current attitude. Intense, projected gravity wells whipped the fighter around onto a new vector, bleeding off velocity to th
row an extra burst of power to the inertial dampers that, theoretically at least, kept the pilot from being squashed by centripetal acceleration.

  Enough gravities seeped through the straining damper field to press Gray back against the yielding nanofoam of his seat; stars blurred past his head.

  “Six missiles still locked on and tracking,” the AI voice of his Starhawk told him with emotionless persistence. “Time to detonation nine seconds…eight…seven…”

  At “three” Gray grav-jinked left, firing passive sand canisters. The enemy missiles were now a few thousand kilometers off his starboard side, using their own gravitics to attempt to match his turn. He kept pushing, kept turning into the oncoming warheads.

  Blinding light blossomed from astern and to starboard…then again…and yet again as three missiles struck sand clouds and detonated. Three down, three to go. He punched up the Starhawk’s acceleration to 3,000 gravities, turning again to race toward the planet.

  As always happened for Gray in combat, a rushing sense of speed, of acceleration washed through him, matching, it seemed the acceleration of his fighter.

  He might not be able to outrun Trash missiles in a flat-out race, but in most combat situations, outrunning them wasn’t necessary. Most missiles held their acceleration down to a tiny fraction of their full capability. If they didn’t, they wouldn’t be able to match a low-G turn by their target, and they would wildly overshoot. So the remaining missiles on Gray’s tail were putting on just enough speed to slowly catch up with him.

  “Two new missiles now locked on and tracking. Terminal intercept in twenty-four seconds.”

  And that was the other half of the equation. Standard Turusch tactics were to fire whole swarms of missiles, sending them at him from all directions, until no maneuver he made could possibly jink past them all.

  “Three missiles of original salvo still closing. Terminal intercept in eight seconds.”

  Gray moved his hand through the control field and the Starhawk flipped end-for-end, bringing his particle accelerator to bear. The three closest missiles appeared as a triangle of red blips, the alphanumerics next to each flickering as range and time-to-impact swiftly dwindled.

  His eyes held one, and a red square appeared around the blip at the triangle’s apex, signifying target lock. He moved his hand and a stream of neutrons turned the missile into an expanding cloud of plasma. He shifted his attention to a second blip, and watched it explode as well.

  The third had vanished.

  “Ship!” he said. “Confirm destruction of all three missiles!”

  “Two anti-fighter missiles confirmed destroyed,” the AI’s voice said. “Negative confirmation on third missile. Two missiles of second salvo still locked on and closing. Terminal intercept in sixteen seconds. Third salvo fired, locked on and tracking. Terminal intercept in thirty-seven seconds….”

  That was the way it worked in modern space-fighter combat…with more missiles fired, and more, and more. Worse, from his mission’s perspective, the more time he spent trying to dodge incoming missiles, the less able he would be to carry out his primary objective, which was to close with Turusch capital ships and destroy them.

  He pulled the Starhawk around until it was again traveling straight for the planet ahead.

  “This is Blue Omega Seven,” he called. “Request clearance for PCO launch on this vector.”

  “Omagea Seven, Omega One,” Allyn’s voice came back. “You are clear for AMSO.”

  “Firing PCO in three…two…one…Fox Two!”

  In space-fighter combat, Fox One signaled the launch of any of a variety of all-aspect homing missiles, including the Krait. Fox Two, on the other hand, signaled a sandcaster launch—Anti-Missile Shield Ordnance, or AMSO. An AS-78 missile streaked from beneath his cockpit, accelerating at two thousand gravities. After five seconds, it was traveling one hundred kilometers per second faster than Gray’s Starhawk and, when it detonated, the individual grains of sand—actually sand-grain-sized spherules of matter-compressed lead—were released in an expanding cloud of grains, each traveling with the same velocity and in the same general direction. Sandcaster missiles were dumb weapons as opposed to smart; protocol required requesting clearance for launch, because a grain of sand striking a friendly fighter at several thousand kilometers per second could ruin the day for two pilots, him and his unintended target.

  Over the tacnet, he could hear other Omega pilots calling Fox Two as they slammed sand at the oncoming missiles.

  In a few more seconds, the sand cloud had dispersed to the point where it created a physical shield several kilometers across. His initial velocity after his turn-and-burn with the enemy ship-killers had been just over twelve thousand kilometers per second; he increased his speed now by an extra hundred kps, slipping up close and tucking in behind his sand wall and drifting at the same speed.

  White light blossomed ahead and to starboard, dazzling even through the stepped-down optical filters of his fighter’s sensors.

  A second nuclear blast, ahead and below…this one close enough that the shell of expanding plasma jolted his ship and sent hard radiation sleeting across the Starhawk’s electromagnetic shielding.

  Gray decelerated, braking hard. Eta Boötis IV was rapidly swelling to an immense crescent just ahead, as thousands of brilliant stars flickered and flashed against the planet’s dark night side—sand grains striking atmosphere at high velocity and vaporizing in an instant. By now, the defensive cloud had either dispersed to ineffectiveness or been swept aside or vaporized by repeated nuclear detonations. But he’d run the gauntlet in close to the planet, and now he was within combat range of the majority of the Turusch fleet.

  The near presence of the planet complicated things, but more for the defenders than for the Blue Omega Strike Force. The planet’s bulk now blocked the line of sight to a number of the Turusch warships in low orbit, provided the gravitational mass for free course changes, and in this world’s case even added an atmosphere that could be used either as a defensive screen or for simple delta-V.

  The other fighters of Blue Omega were scattered across the sky now, each operating independently of the others. Gray could hear the cockpit chatter, but had to focus on his immediate situation. His wingman…where the hell was his wing?

  There she was—Blue Omega Eight, two thousand kilometers aft and to starboard. Katie Tucker was engaging a big Turusch Echo Sierra—an electronic scanner vessel. That, at least, was what Intelligence thought those monsters might be, with their far-flung antennae and hundred-meter sensor dishes.

  Confederation tactical doctrine suggested that pilots work together in wings for mutual protection, but standing orders didn’t require it. One Starhawk could kill a Turusch capital ship as easily as two, and a single one of those thermonukes they were tossing around could take out a pair of gravfighters if they were too close together.

  “This is Blue Seven,” he reported. “I’m going to try to get in close to the objective.”

  Objective meaning the Marine perimeter in Haris, Eta Boötis IV. It took him a moment to orient himself as his AI threw up the curving lines of longitude and latitude on the image of the planet. Haris was tipped at an extreme angle, with an axial tilt of nearly 90 degrees. At this point in its year, Eta Boötis was 30 degrees off the planet’s south pole, the Marine perimeter at 22 north.

  There it was…a green triangle marking the Islamic base and the Marine expeditionary force sent to protect it, just now rotating into the local dawn. Turusch ships swarmed above and around it, or poured fire down from orbit. It was what carrier pilots liked to call “a target-rich environment.”

  Gray loosed another half dozen missiles, then spotted a special target. Three thousand kilometers ahead, a Turusch fighter transport lumbered just above the planet’s cloud-choked atmosphere, fighters beginning to spill from her bays.

  “Blue Omega Leader, Blue Seven,” he called, bringing the nose of his Starhawk around and accelerating. “I have a Fox Tango dropping Toads. Eng
aging….”

  “I copy, Blue Seven. Blue Five! Blue Four! Get in there and give Blue Seven some backup!”

  “Ah, copy, Blue Leader. On our way….”

  The Turusch heavy fighters code-named “Toads” by Confed Military Intelligence were big, ugly brutes thirty meters in length and half that thick. Less maneuverable than their Confederation counterparts, they could accelerate faster, and individually, could take a hell of a lot more punishment in combat. As Gray swung onto an attack vector with the transport, the Toads already released had begun boosting into intercept courses.

  “Fox One!” Gray shouted over the net as he released a Krait. “And Fox One…Fox One…Fox One!”

  The red-and-black Toad transport was a prime target, easily worth the expenditure of four nuke-tipped Kraits. Confederation fighter pilots steadfastly refused to refer to Fox Tango transports as “carriers.” They insisted that the code name Fox Tango, in fact, was short for “Fat Target” rather than the more prosaic “Fighter Transport.”

  Missiles released, Gray snapped out an artificial singularity to port and rolled left, breaking off the run. The enormous transport was throwing up a cloud of defensive fire—sand, gatling KKs, particle beams, and point-defense HELs.

  The Toads already released by the transport were falling into echelon formation as they accelerated toward Gray’s fighter. There were five of them, and they were already so close they were beginning to loose missiles at him.

  He plunged for atmosphere.

  By now he’d bled off most of his velocity, and was dropping toward the planet’s night side at a relatively sedate eight hundred kilometers per second. Using full reverse thrust, he slowed still further as his Starhawk’s crescent shape flattened and elongated somewhat for atmospheric entry, growing aft stabilizers and a refractory keel. He was moving at nearly thirty kilometers per second, eight kps faster than the planet’s escape velocity.
