Oh, and another batch of candidates for this would definitely have to be the three "battlecruisers" built for Jackie Fisher's
Baltic project (Glorious, Furious, Corageous). Had they actually been used as intended, they would've not only failed spectacularly, but the plan involving them would probably be a massive fiasco as well. And not to mention they were structurally unfit to even use their main weapons without damaging themselves. Forget about being able to survive any sort of battle damage. Luckily they were quickly converted into carriers...
