**Current Version** 2.1.0. [Updated 2024.08.06]

**HUGE UPDATE TO PD CALCULATOR: Now has a text guide! See below**

Updated for PD changes. Able to compare 10cm Rail (any # shots), 10cm Laser (including size reductions) and any gauss. Able to accommodate fighter designs.

Able to help design efficient CIWS

**CIWS is currently bugged in Aurora 2.5.1. Do not use until this has been fixed**Able to calculate for point blank fire and vs. laser standoff missiles.

Able to determine approximate number of leaks given fire control settings. (

**Huge shoutout to forum user bean for the binomial distribution spreadsheet**). bean's missile analysis is what inspired me to dig into the grit of this calculator again, and their knowledge of excel functions was the breakthrough moment I needed to update my sheet.

Determines number of CIWS needed to catch leaks, AND/OR HS of shields needed to catch leaks.

Determines HS of shields needed to fully recharge-tank leaks if you don't like CIWS.

Determines true cost of PD in HS, accounting for MSP required due to weapon misfires, including CIWS to catch leaks if desired.

**Now accounts for missile decoys as of v. 2.1.0!**Calculates 2 sets of values: The "Best" value uses the BFC settings with the highest %chance to hit. The "Efficient" value also includes the total HS of PD assigned to the BFC to design a smaller BFC that allows you to save space. Total missile defense should be near-parity in most cases, so the 'efficient' calculations will likely save 1-2 total HS on your design.

**Text Guide to use the calculator**:

If you are a vision impaired individual and have suggestions on how to make my calculator or guide more accessible please reach out to me. I will happily and gladly make improvements.

**Changelog:**2024.08.01 - Recalculated for HS needed to intercept 10 volleys, up from 1. Added summary information detailing HS of MSP needed per additional 10 volleys intercepted.

24.08.01 - Bug fixes on turret cost calculations, and addition of actually how many turrets are needed (not just total size).

24.08.03 - Testing confirms shots per missile are not capped to 10, so uncapped max shots in calculator

24.08.03 - fairly significant bug affecting turret costs (was calculating ~20% too high, and I found that my formula wasn't accounting for laser range mods or gauss size below full.

24.08.06 - Fixes a MSP HS bug (was reporting 25x too large) and added missile decoy, ECM/ECCM tech and tactical officer bonus functionalities. Added comment for Missile Decoys to help you estimate decoys if you haven't captured a missile yet.
