The Kite caught the Rraey cruiser napping.
The Skip Drive was a touchy piece of technology. It made interstellar travel possible not by propelling ships faster than the speed of light, which was impossible, but by punching through space-time and placing spaceships (or anything equipped with a Skip Drive) into any spot within that universe those using the Skip Drive pleased.
(Actually, this wasn’t exactly true; on a logarithmic scale Skip Drive travel became less reliable the more space there was between the initiation point and the destination point. The cause of what was called the Skip Drive Horizon Problem was not entirely understood, but its effects were lost ships and crews.
This kept humans and other races that used the Skip Drive in the same interstellar “neighborhood” as their home planets in the short run; if a race wanted to keep control of its colonies, as almost all did, its colonial expansion was ruled by the sphere defined by the Skip Drive horizon. In one sense this point was moot; thanks to the intense competition for real estate in the neighborhood humanity lived in, no intelligent race save one had a reach that came close to its own Skip Drive horizon. The exception was the Consu, whose technology was so advanced relative to the other races in the local space that it was an open question as to whether it used the Skip Drive at all.)
Among the many quirks of the Skip Drive, which had to be tolerated if one were to employ it, were its departure and arrival needs. When departing, the Skip Drive needed relatively “flat” space-time, which meant the Skip Drive could only be activated when the ship using it was well outside the gravity well of close-by planets; this required travel in space using engines. But a ship using the Skip Drive could arrive as close to a planet as it wanted—it could even, theoretically, arrive on a planet surface, if a navigator confident enough of his or her skill could be found to do it. While landing a spacecraft on a planet via Skip Drive navigation was officially and strongly discouraged by the Colonial Union, the Colonial Defense Forces recognized the strategic value of sudden and unexpected arrivals.
When the Kite arrived over the planet its human settlers called Gettysburg, it popped into existence within a quarter of a light-second from the Rraey cruiser, and with its dual rail guns warmed up and ready to fire. It took the Kite’s prepared weapons crew less than a minute to orient and target the hapless cruiser, which only at the end could be seen trying to respond, and the magnetized rail-gun projectiles needed less than two and a third seconds to travel the distance between the Kite and its quarry. The sheer speed of the rail-gun projectiles was more than sufficient to pierce the hide of the Rraey craft and tunnel through its innards like a bullet through soft butter, but the projectile designers hadn’t left it at that; the projectiles themselves were designed to expand explosively at the merest contact with matter.
An infinitesimal fraction of a second after the projectiles penetrated the Rraey craft, they fragmented and shards vectored crazily relative to their initial trajectory, turning the projectile into this universe’s fastest shotgun blast. The expenditure of energy required to change these trajectories was naturally immense and slowed down the shards considerably. However, the shards had energy to spare, and it simply meant each shard had more time to damage the Rraey vessel before it exited the wounded ship and began a long and frictionless journey through space.
Thanks to the relative positions of the Kite and the Rraey cruiser, the first rail-gun projectile struck the Rraey cruiser forward and starboard; the fragments from this projectile tunneled through diagonally and upward, not-so-cleanly chewing through several levels of the ship and turning a number of the Rraey crew into bloody mist. The entrance wound of this projectile was a clean circle seventeen centimeters wide; the exit wound was a ragged hole ten meters wide with a gout of metal, flesh and atmosphere blasting silently into the vacuum.
