Hehe. The alien ships stalked me, at 10k km, for about 20 days, following me around as I surveyed some more survey points.
Then, suddenly, they moved away from their usual 10k km stalking range, and moved to 3m km, from where they started to launch salvos of size 4 missiles at me.
They must have gotten to a point where my ships in their system, using active sensors, pissed them off enough to attack me.
My AMM, and gauss cannons had no problem destroying the incoming groups of 3 salvos, 1x3 and 2x6 missiles. In fact, I shut down 6 of my 8 point defence missile launchers on my escorts to save ammo, and the remaining AMM missiles and gauss cannons were still enough.
My salvo of 4 MIRV missiles, split into 12 strenght 4 and they all hit the one ship that was using active sensors in the group. There seemed to be no anti-missile capability at all on the enemy ships. Unfortunatly, I did not take out it's sensor. It did take out it's missile launcher though, bringing the incoming salvo's down to 2x6, and crippled it's engines, reducing it's speed to barely over 2000km/s
I almost ran out of AMM. But the enemy ran out of missiles before I did, so I had some spare AMM left to fire at one of the enemy ships, sanding down it's armor.
I proceeded to close in on their fleet, and killed all 3 ships at point blank range, using my gauss cannons :evil grin:
Now, backing out of their system, having secured my side of the jump point with an ambush fleet, I'll let my skill 230 diplomatic team do it's magic on them to calm them down.
