The Steel Federation had been conducting a string of successful campaigns - a small Precursor fleet outpost was wiped out with only minimal losses; a nest of Rakhas was wiped out in ground combat; and a primitive alien race with over a billion members was pacified and brought under colonial rule.
The technology of energy shields had recently been improved to the point that it was deemed ready for installation on the warships of the fleet - no longer would they be tanking damage directly with their armored hulls; instead a regenerating 85-point shield would deflect all but the most severe blows.
Thus, when a new Precursor base was discovered at 40 Eridani, the fleet was dispatched to great fanfare. Who were these soulless machines, that would think to deny the supremacy of the Human race?
During the approach to the planet that the Precursors had claimed, higher-than-expected resistance was encountered. Dozens of missiles were being fired in five minute intervals. The fleet's point defense systems engaged, but the Precursor missiles were devilishly devious, operating at high speed with multiple decoys. Nuclear flames rippled over the fleet; but the new shields proved true, and armor damage was minimal.
The Precursor base was nearly within range of the fleets large-bore laser weapons when they changed tactics - instead of the dozens of large anti-ship missiles every couple of minutes; they instead opened up with
hundreds of tiny missiles every
five seconds. Although each of the diminutive warheads inflicted negligible damage, there were so many that they overwhelmed shields, then sandpapered the hulls of targeted ships, digging to the vital systems below. Within 30 seconds, three fleet warships had exploded. An order to retreat was given; but before they finally managed to escape out of the range of the deadly stream of fire, three more ships had been blown to pieces.
The remaining fleet limped back to Sol, where they would be repaired. The great shipyards sprang to life, laying down the hulls of a dozen new vessels. The fleet
would be back, stronger and more technologically advanced.
