All-big-gun marketing and practical technology

The phrase all-big-gun battleship was useful marketing rather than a literal description without precedent. Earlier rated sailing ships and HMS Warrior could also claim uniform or overwhelmingly large batteries under broader definitions. Dreadnought's twelve-inch guns were familiar to existing crews, making rapid entry into effective service more likely than an untested fourteen-inch alternative. The design therefore illustrates why navies often build near the leading edge rather than at its most expensive and unreliable extreme.
