Could Surcouf replenish its ready-use magazines while submerged?

The answer remains uncertain: a viewer identifies waterproof storage outside the pressure hull, and the initial recollection of submerged reloading may concern another submarine.

Whether Surcouf could replenish its ready-use magazines while submerged remains unresolved. A viewer places the ready ammunition in waterproof boxes behind the turret, outside the pressure hull, which would prevent replenishment underwater. Dr. Clarke accepts that this may be correct and acknowledges that his recollection may concern another cruiser submarine. The initially affirmative answer therefore cannot establish Surcouf's actual arrangement.
