Naval weapons experiments worth repeating

Which reconstructed naval weapons experiment would be most valuable to repeat under better conditions?

Suggestions include realistic wooden-hull spalling tests, reconstructions of Hood and Bismarck's destruction, controlled bombing trials, and experiments on turret flashover.

Repeating the Mythbusters wooden-hull spalling trial would require timber as close as possible to the original ships' wood, despite the shortage of old-growth oak. Another proposal uses modern engineering analysis to reconstruct Hood's destruction and Bismarck's final action, with full-size replicas suggested as the ideal experimental models. A repeat of Billy Mitchell's 1920s bombing trial would use period aircraft and ordnance while enforcing inspections between attacks. The concern is that disputed procedure and missed inspections obscure how much damage each raid caused. The final proposal measures the effects of shell hits on or near battlecruiser turrets containing accumulated propellant residues from poor handling. Varying impact strength and residue buildup would test the conditions that produce flashover.
