I dropped a 500 pound bomb on a Fairmile. No kill, no flames, it barely smoked, kept firing guns.
I don’t know if bombs are nerfed (still) or the Fairmile has been deliberately over modeled. Either way, your damage model is a hot mess.
This video is from a bug report I did well over a year ago. Same issue, still not fixed.
A 500 pound bomb on a boat the size of a Fairmile should have blown it right out of the water, no questions asked.
