ISC: Plasma I and other refits

ISC Plasma-I adjustments

The ISC's defensive plasma-I don't work the same as in SFB: only 1 plasma-I can be fired towards capital ships per turn, for all launchers. In OP patch 25412, this is for each group mount of Plasma-I, so more plasma can be lobbed at the enemy.

Glancing at Taldren 'readme's concerning the changes done, I've found that the BPV adjustment is roughly based on the following calculation:

BPV added = (# plasma-I) * 1.5

Additionally, SFB's ISC SSDs show the ISC with the plasma-F installed only. Calculations are needed to figure out each prior refit.


previous ISC refits

All below are based on the SFB's version of ship's BPV and SSD, noted in reverse to demonstrate the downgrade path

  • Z refitted ship cost: base SFB BPV + (#plasma-I * 1.5)
  • Y refitted ship cost: approx: base SFB BPV - (#plasma-I * 3)
    • 2 plasma-I removed: -7 BPV
    • 4 plasma-I removed: -13 BPV
    • 6 plasma-I removed: -20 BPV
    • 8 plasma-I removed: -26 BPV
    • 12 plasma-I removed: -31 BPV
  • P refitted ship cost: Y-refitted ship + -4.5 BPV * Plasma-S
    • Plasma-S downgraded to Plasma-G.
  • W refitted ship cost: P-refitted ship + (-4 BPV * PPDs removed).
    • PPDs removed.
  • basic design, no refit: W-refitted ship + (-1 BPV * ph-3s removed).
    • ph-3 removed.


The years for the refits are also important. I'll just use Taldren's dates. If the ship post-dates any refit date, the refit will be included in the base design of this ship.

  • W refit in YFA +2 (2265)
  • P refit in YFA +5 (2268)
  • Y refit in YFA +7 (2270)
  • Z refit in YFA +16 (2279)


ISC X ships

ISC X1 x-ships also need to be adjusted for the above. Additionally, they need to be compensated for the Plasma-L -> Plasma-I downgrade. There really isn't any precedence to this, so I used common sense:
