Holly molly! I may need to review my full HRPs build... :-/we also fired at the same FdL with no bulkheads and each shot did the same damage to it as when firing at military bulkheads.
The game simulates the supposed damage reduction effect of military bulkheads by increasing the base hull hit points by 95%. This is correctly reflected in both the coriolis and the in-game shipyard hull strength values. Note, ‘base hull’ not HRP.[...]all of the above will take damage at the same rate, with the same modifiers, with the only benefit of the military bulkheads being their simple (and quite modest) increase in hitpoints.
So...lightweight, reinforced and military bulkhead do not offer any damage reduction? But mirrored and reactive do? Sounds like a bug to me...
Has this been reported as a bug? If so, did FD return on that and confirm it is not a bug? And if not, would you have a video demonstrating this? I'd be glad to report that...
