“Combat mode,” she snapped. “Formation break!” The Dragons’ adaptive nanomatrix hulls shifted and flowed, changing from sleek, black deltas to Y shapes, the weapons pods extended at the ends of the three forward-canted wings. Those two incoming missiles had curved upward, following the flight of Draco squadron Stardragons all the way up from the deck. Lieutenants Allende and Larson, bringing up the rear of the formation, loosed bursts of KAM pellets—kinetic-kill anti-missile projectiles that slammed into the Slan warheads and detonated them 10 kilometers astern.
Within Connor’s in-head display, a Slan destroyer changed vector to intercept them, the image magnified to show the flat blade of a hull and eight projecting shark fins, the vessel painted a flat white with bold red slashes and blotches. Little was known about the Slan save that they were another Sh’daar client race. The characteristic color scheme of their warship hulls, Intelligence thought, might represent some predator from the Slan homeworld, but even that much was pure guesswork.
She selected the destroyer with her inner eyes, selected a weapon—a VG-44c Fer-de-lance antiship missile—and clicked the blinking launch icon in her mind. “Ferdie armed!” she cried. “Fox One!”
A nuclear-tipped missile slipped from her low-keel fin and streaked toward the destroyer. The other fighters were peeling off in every direction, engaging a sky filled with targets …
The star 36 Ophiuchi was a triple-star system just 19.5 light years from Earth, and 10 light years from the enemy-occupied system of 70 Ophiuchi, and the world Osiris. The A and B components, both K2-class orange stars, circled each other in an extremely elliptical mutual orbit lasting 570 years, the two coming as close to each other as 7 astronomical units and receding out to as far as 169 AUs. Currently, they were 30 AUs apart, and 36 Oph B appeared as a tiny orange spark in the blackness well beyond the nearer disk of 36 Oph A. A third, smaller red-orange star, 36 Ophiuchi C, orbited the two main stars at a comfortable distance of 5,000 AUs, or some eight hundredths of a light year, a spark so wan and dim it could not be picked out by the naked eye.
The system was still young—less than a billion years old—and filled with asteroidal debris and comets. A dozen comets blazed with icy light, their tails smeared across the heavens away from the orange sun. The planet dubbed Arianrhod by its colonizers was properly 36 Ophiuchi AIII, the third of four small and rocky planets. Located a little more than half an AU from its sun, it lay near the center of the system’s habitable zone. Mostly covered by liquid water, the world was twice the mass of Earth. The major landmass was the Caer Arianrhod Archipelago in the southern hemisphere, and was the location of the research colony of Silverwheel.
Arianrhod offered Confederation xenoplanet specialists the splendid opportunity to study an Earthlike planet still in the final stages of formation. Earth itself must have looked much the same 3.5 to 4 billion years ago. The atmosphere was a poisonous brew of carbon dioxide, methane, nitrogen, and sulfur dioxide. Volcanoes dotted the vast and rolling oceans, and asteroids and comets continued to slam into the young world, generating apocalyptic tidal waves. Silverwheel, most of it, was underground, as was the large USNA naval base protecting it. The land, when it was above water, was rocky, barren, and lifeless.
Yet, despite this, life bloomed in the oceans, raising questions about the nature, variety, and extensiveness of early life in Earth’s seas. It was known that life had appeared in Earth’s seas within a scant few hundred million years of the formation of a solid crust … but that life had remained single-celled and relatively simple for the next 2.5 billion years or so, and hadn’t learned how to manage the multicellular trick until about a billion years ago. Multicellular life forms, some of them as complex as things like colonial jellyfish and free-swimming tunicate worms, had already evolved in Arianrhod’s seas.
Theorists had suggested that life might have evolved not once, but many times on Earth; others suggested that radiation from the planet’s sun had given evolution a swift kick in the ass. Arianrhod offered xenobiologists the unparalleled opportunity to watch the process in action. The planet had been named deliberately for an ancient Celtic goddess of fertility, rebirth, and the weaving of cosmic fate. Someday, in a billion years or so, this world might be another Earth; in the meantime, it offered Humankind an unparalleled chance to study planetary evolution. Silverwheel’s twenty thousand inhabitants were almost all scientists and their families.
The Slan attack had not been entirely unexpected.
Osiris, 70 Ophiuchi AII, had been hit and overrun twenty years ago by a combined Turusch-Nungiirtok assault force. Osiris, though, was one of a handful of so-called garden worlds, planets with oxygen-nitrogen atmospheres and extensive biospheres where humans could live and work without cumbersome biosuits or nanoskins. The government council at Silverwheel had been hoping that the enemy wanted to take over pleasant, Earthlike worlds, not poisonous biomes-in-the-making like Arianrhod. And as year followed year, they’d begun to relax. Arianrhod did not appear to be on the enemy’s target list.
Until now. Unlike the civilian government at Silverwheel, the Navy had long suspected that one or another of the Sh’daar client species would make a grab for 36 Ophiuchi, and deployed three fighter squadrons to defend the system. Two, the Dracos and the Reapers, had been stationed at the naval base protecting Silverwheel, with a third, the Blood Knights, operating out of an orbital base called Caer Gwydion. Picket drones in the outer system had noted the approach of a sizeable naval force two days ago, apparently coming from the general direction of 70 Ophiuchi.
The fleet, which had turned out to be Slan, was a mix of the lance-blade destroyers and a large number of planetary bombardment vessels, code-named Trebuchets by Confederation Military Intelligence. The three squadrons had been flying almost nonstop, with brief returns to base for rearming and repairs between missions. Caer Gwydion had been struck by a trio of two-hundred-megaton warheads ten hours ago and turned into an expanding cloud of hot gas.
But the surviving fighters continued to hurl themselves at the enemy force, as their numbers dwindled and casualties mounted.
Lieutenant Sheridan’s Stardragon took a direct hit from a Slan beam weapon, her fighter vaporized in an instant, like a moth in an open flame.
“All Dracos!” Connor called. “Vector on the Trebs on planetary approach! Let’s see if we can break up that attack!”
The alien Trebuchets were ungainly, boxy affairs utterly unlike the sleek destroyers. Each was a little more than 200 meters in length, painted black with random, bright green slashes, and carried piggyback a single massive nuclear missile with a five-hundred-megaton fusion warhead. They approached in waves, lining up on the target planet and loosing the missiles as they streaked inbound. Even from 15,000 kilometers out, Connor could see the periodic twinkles of detonations concentrated on the northern coast of the Sumatra-sized landmass where Silverwheel lay buried, and more planetbusters were inbound. Even the deeply buried research colony wouldn’t be able to hold out for much longer against that savage planetary bombardment.
Dropping into a trajectory that put her on the stern of one of the inbound Trebs, she selected the target with a thought, then thoughtclicked the mind’s-eye icon for a VG-10 Krait, armed it, and loosed it, sending the smart missile streaking in toward the falling enemy bomber. Before the missile could cross the intervening gulf, however, the enormous missile strapped to the Treb’s dorsal hull released, drifted clear, and then began accelerating toward the planet. Connor targeted the missile as well, sending a second VG-10 streaking after it.
She couldn’t take the time to watch the results of her shots, but spun her Stardragon end for end, decelerating sharply, then spun through 90 degrees to acquire another target. She marked a second Trebuchet and sent another Krait smart missile flashing toward it.
Surrounding space was filled with pulsing flashes of silent light, the brilliant detonations of nuclear warheads in space, and with softly glowing clouds of expanding debris, chunks of shredded spacecraft, and occasional disabled fighters
