Hi everybody,

in my try to do a complete BV2 database similar tot he Master Unit list i stumpled upon the missing BV values for warships regarding Version 2.0
So i grabbled my StratOps and tried to do it my own but then stumpled again…no BV2. I did matched the ones given for some designs and maybe i´m missing something.

I did some examples according tot he rules in StratOps Page 161.

Calculating the defensive BV modifier is simple, but i happens i´m missing something in the offensive one. Here are my examples:

Soyal Heavy Cruiser

Official BV2: 107.892
Self calculated BV2: 81.168


As it says in the rules, you should take the highest BV arc and calculate it at 100%, the second highest also (except for overheat), the opposite arc oft he first also and the remaining arcs at 25%. So i did it and received the following Battle Values fort he soyal:

Nose   100%   23856
RBS   100%   11016
Aft   100%   16632
LBS   25%   2754
AR   25%   2754
AL   25%   2754
FR   25%   3504
FL   25%   3504
Total Arc BV: 62767,56

A total weapon BV of 66774 modified by the Offensive speed factor. Given the soyals maxthrust of 5 this will be 0,94 = total offensive BV: 62767,56

Offensive Speed factor: 0,94
Defensive BV: 18400
Offensive BV: 62767,56
Total BV: 81.168

Next Example is
Athena Cruiser

Official BV2: 107.892
Self calculated BV2: 86.336

 
Nose   100%   22752
RBS   100%   11088
Aft   100%   48390
LBS   25%   2772
AR   25%   3637,5
AL   25%   3637,5
FR   25%   3637,5
FL   25%   3637,5
Total Arc BV: 99552
Offensive Speed factor: 0,77
Defensive BV: 9680
Offensive BV: 76655,04
Total BV: 86336


What did i do wrong?

« Reply #2 on: 07 February 2019, 07:32:21 »
First of all: Thanks for the answer, but there is still some missunderstanding.

Example for the soyal given:

BV of Nose arc is sayed to be 47712.0 (base weapon BV) but Nose mounts the following:
Mass Driver (Medium)+11760.0 BV
Naval Gauss (Heavy) +6048.0 BV
Naval Gauss (Heavy) + +6048.0 BV

In total this means 23856 BV (Thats half the BV taken into account above)....why is this wepaon base bv duplicated?

Also the BV for the weapons mounted in Front left ist:
Naval Autocannon (NAC/30)   5688,0 BV
Naval Autocannon (NAC/20)   3792,0 BV
Naval Laser 45   1134,0 BV
Naval Laser 45   1134,0 BV
Naval Laser 45   1134,0 BV
Naval Laser 45   1134,0 BV
Total: 14016,0 BV

Why did you calculated with a base weapons bv of 23496.0?
