Wing turrets placed the Invincibles' heavy guns off the centreline, with consequences for stability and maintenance. Superfiring offered another arrangement, with a raised turret able to fire over a lower one. The criticism is that examples were already afloat and the naval architects and engineers considered the arrangement viable. Fisher remained unconvinced, so the class kept the wing mounts.
