20mm damages medium ships on my system but can't finish them off. That seems realistic to me and I wasn't disappointed
But 50cals can tear a ship to pieces and yes guncamera film shows ships exploding under 50cals getting into boilers (no ammo deck-stacks on merchants) - they were a fearsome weapon when firing into
the deck from above
Remember that the rounds are already travelling at ~200-300mph before being fired from an aircraft. Kinetic energy. Rounds fired from static weapons would be less destructive and no aspect shots from our position on the surface, we just see the armored side of a ship mostly
Hi elanaiba and thanks for the truly marvellous sim!
