Really? I'd have thought flak and AAAf beams would be more effective.
I have way too much time and ran tests using a Deimos, just by removing the weapons I didn't want. 4 Taurvi bombers were loaded with 4 Shivan Bombs each and entered the mission area after 5 seconds.
I ran the test with no weapons, all weapons, only blobs, only flak, and only beams. With no weapons, the Deimos went down in 2-3 minutes. With blobs it got about a minute more life, with flak the corvette was damaged and a number of bombers were destroyed after all bombs were launched. With beams after all bombs were launched the Deimos was almost destroyed. With all its guns the Deimos mauled the bombers in around four minutes, and lost half its hull.
I ran these tests a couple of times and there was a fair amount of variance, but I'd still take more flak and beams over blobs (An increase proportional to the number of blobs removed).
The issues I can think of with this testing include using AI pilots which didn't always perform exactly the same manoeuvres, and the different numbers and positions of turrets on the Deimos. I didn't want to set all the turrets to one weapon to retain some semblance of weapon balance - a shipful of AAAf beams would obviously be lethal.
Yay... Pulseguns... I hate those things
