[Spaceships] 'Triple' bomb size instead of triple ammo count?

[vicky_molokh]

Greetings, all!

According to Spaceships 4, bombs are 1/3 the size of missiles, and launchers can load 3 bombs instead of one missile. That's a bit strange, given that bombs are usually meant to do lots of damage, preferably in one hit. So, I'm asking: if I want to use a bomb the size of a whole missile, not 1/3, are there any things I should be aware off, or should I just seek the stats of a missile warhead with (SM of the launcher's default missile)+1?

Thanks in advance!
