Immediate explosion upon catching fire in naval bluewater fleet

My crew is fully upgraded with fire fighting skill, but upon catching on fire, my ship exploded in seconds. This issue is particularly obvious in SMS Bayern and SMS Sachsen which I got hit in the engine compartment and then the ship exploded within few seconds. Despite I had immediately pressed the fire extinguishing button, my ship still exploded in seconds. Is anyone else experiencing this issue?

Does it say ammoution load exploded

If the fire is in your ammo storage or shell room your chances of catastrophic explosion go up significantly. The alarm sounds sharper and more urgent compared to a fire in another location. Researching ammo wetting and ventilation helps quite a bit.

Sometimes, I did not look at it all the time

I found some ships are just extremely vulnerable to fire explosion. I fully researched SMS Bayern, still it catches on fire very often and then explodes.
