The Bonhomme Richard, whose size ranks second in the U.S. Navy fleet to that of an aircraft carrier, sustained severe damage from the flames, leaving the ship listing to the starboard side, its superstructure collapsed and melted.
Sobeck said he believed the ship could be repaired and returned to duty but that the Navy had not yet decided whether to undertake the massive task.

Can we list the ways this is problematic?
For steel:
250C, loss of the paint system'
350C loss of structural integrity and distortion
700C loss of metallurgical structure and properties
1400C melting point
Aluminum melts at about 600C which may be why the superstructure is compromised, Even if it didn't melt it can be permanently affected strength wise.
I've attached an old article from LR that I have saved, because a fire is something you may never have to deal with but when it does....
