wycca has asked for a working ship design spreadsheet here. Rather than continue that old post I decided to open a new one with my effort. I designed this some years ago but I have now added some missing items (double hull, 5-rack MB's) and changed miniaturisation formula to reject selecting items beyond your selected tech levels (gives #N/A). I use it occasionally to plan LR and other ship designs and have done some checks on the updates but let me know if you notice any errors.
Ship Design Spreadsheet 2009:
[EDIT ] V2 spreadsheet to correct miniaturisation limit to 50 levels for all items (not just weapons) as spotted by Cyneheard
[EDIT2] V3 spreadsheet to correct Special item miniaturisation to use correct field
[EDIT3] V4 spreadsheet fixing reserve fuel tanks & AMR on mediums getting #N/A at low tech levels
[EDIT4] V5 spreadsheet removing tech level check per Refsteel below but warns if using higher than tech level, plus minor fixes
[EDIT5 30Mar11] V6 spreadsheet fix missile cost & space plus melee weapon space to use correct miniaturisation table
[EDIT6 08Apr11] V7 add bio weapons, correct game manual stats for tech levels (Fusion bomb, Hyper-X) and for some missilex5 costs & size
[10Apr11] Minor update for Propulsion tech level 1 showing #N/A
[12Jul13] Re-add V7 as attachment since earlier link broken, redo 28Jul13 & 8Aug13 & 11Aug13. If attached file goes missing try following link.
