Note that explosives don't do their nominal weight in damage.
While this is correct, you values are off.
a 1,000 lb bomb does exactly 1,000lb of damage, and that's why all object damage values in the settings are given in 1,000lb bombs.
GP bombs of AH:
4,000lb = 3,125 damage
2,000lb = 1,718 damage
1,000lb = 1,000 damage
500lb = 562 damage
250lb = 313 damage
100lb = 156 damage
AP variants to 150% damage at 20% damage radius
SAP variants do 125% damage at 33% radius
HC/LC variants do 75% damage at 125% radius
As for the topic, I had somewhat neglected torps in the past. Right now I only have damage values for the US and the Japanese Type 91 torpedo, which according to my numbers do (did?) both 4,687 damage - but in this case I'd rather like to see someone confirming these numbers.
According to Oceania's settings (at least what I have in offline mode):
14,060 lbs for battleship
7,030 lbs for carrier
3,520 lbs for cruiser
But these can be modified by whoever loads and manages the arena.
The standard SHIP value for the MA is 1.56, means DDs and CAs both take 1,560lb of damage to be sunk. (That's why a single Jabo can easily send a CA to the bottom).
CV and BB damage values are not shown in the object settings at all.
