Lucider forward armament: Shivan Super Laser (2x) 15000 damage per shot per turret= 30000 damage per dual shot and 10 second fire wait.
Ravana forward armament: 2x SRed: 8708 per shot (17416) and 17 second delay
+
2x LRed: 81529 per shot (163058) and 17 second delay = 171766 damage per 17 seconds.
Ravana hull: 100000 = 3.33 dual shots from lucifer = 40 seconds to live
Lucifer hull: 800000 = 4.65749916 shots from Ravana = 85 seconds to live
Therefore, the ravana is is capeable of about 6x as much damage per shot, however has 1/8 the hul of the lucifer. In any attack where the lucifer and ravana faced ANY other ship (not shooting back) cruiser and above, the ravana would drstroy the target first, but would receive more damage during that time.
NB: all above data is based off Zylon Bane's Beam FAQ, as well as the FS2 ships table, and the FS1 weapons table (for the shivan super laser). Calculations done with google.
