The game lists 10kT AND 5kT for the yield of the subroc nuclear warhead. I -think- it should be 10kT. I don't know what the game is using.
It looks like you are using DB3K_467, a very old database (March 2017). As you can see, if you upgrade to the current database, DB3K_482, then the correct warhead is in place.
