I think I know what happened here, but first, let me explain how the kill system works. The kill is not awarded to the ship that gets the last shot, but the ship that does the most damage. The damage inflicted must also be above 30%; if the ship with the highest percentage has less than that, nobody will get the kill. Finally, beams
do not count for kill points for some reason. If a ship is damaged by beams, the game acts as if the ship only had its original strength minus the amount of damage done by the beam and only uses this value when determining kills. It's weird, but that is how it works.

So what probably happened here was that the Pax jumped in, was shot up by the the Hedetet and the Mjolnirs with beams only, but a nearby Alastor happened to get a couple of shots on it while the beams were firing. The Alastor could not have gotten the last shot since its Subach HL-7s do not have the "big ship" tag, so the beams got the kill and did almost all the damage; out of whatever Pax hull strength that did not get damaged by beams (a very small amount), the Alastor got most of the kill.
You lot suck!
You're supposed to have played this mission a hundred times - the Pax was a Deimos corvette, yes? Starting to see where I'm going with this?
hey I recognized what mission this was right after seeing "Pax" in there...
