Can AP and incendiary bombs destroy bunkers?

In air battles some of the most annoying AI targets are the bunkers(dropping bombs are ineffective unless they are really strong or it is a direct hit).
In real life, AP bombs and incendiary bombs can destroy bunkers. AP bombs i dont know, but when i played a dynamic campaign in battle of britain(on the german side), when i dropped an incendiary bomb it was ineffective.

AP - Armor Piercing → you need direct hit aswell.

And incendiary → it’s dropping some kind of fuel and ignite it

A bunker is most of time damn thick → no effect on the inside.
