A 24-inch bore is imagined as large enough to carry a 21-inch torpedo with protection around it. The proposal assumes that this packaging would let the torpedo survive firing from the gun. A fifteen-gun ship is then imagined launching a broadside over roughly 50,000 yards before the weapons enter the water. These are speculative estimates within the design exercise, with no tested gun-launched torpedo system identified.
