And by WiH, the Vasudans haven't overhauled their beam cannon arsenal anywhere near as much as the Terrans have theirs. The BVas, SVas and VSlash still constitute the vast majority of their anticap beam arsenal.
Citation needed. As someone with a BP badge, you might have info that we don't, however us players haven't seen any of the new Vasudan warships, nor have much information on them
(as far as I know). All we know is that older warships and their logistics ship are fitted with pulse weapons and energy flak, which I don't think allows us to draw conclusions regarding the Vasudan's current beam tech & doctrine.
That being said, it makes a good amount of sense. I think the FS2 era zod beams are amazing, and I can see them choosing to create ships that carry as many beams as their Terran counterparts rather than inventing a whole new beam system.
Fun FREDing exercice: replacing TerSlash & TerSlashBlue with VSlash on Terran corvettes. Alright, time to break out the ol' spreadsheet:
TerSlash damage per salvo: 4,116.00
TerSlashBlue: 5,747.70 (1.4 * TerSlash)
VSlash: 8,820.00 (2.14 * TerSlash & 1.53 * TerSlashBlue)
Alright, time to open up FRED & see how the beam switchero goes
