A troop transport carrying Engineers to an alien outpost got blasted by precursors in a system that I THOUGHT I had secured... Unfortunately, the fleet was undergoing its' first modernization program at the time(This is my first REAL game of Aurora, 37 years in and loving it).
Fortunately, that was two years ago, and 7th fleet's command ship,Hellena, just detected the offending vessels 380m kms out. Launching fighters now - Finally, a chance to test out my carriers' strike groups.
108 Strength 4 nuclear detonations on target (Which is a 100% hit rate (3 missiles per fighter, 36 fighters).... And no sign of any internal damage.
Time to close the range, I suppose.
One day and 50 strength 4 detonations later... 2 new wrecks. Salvage ships en route. Strangely, the hostile vessels made no attempt to return fire, put up any sort of point defense at all, or even to attempt to fleet. They just sat there and ignored the nukes going off outside.
