The limits of a 72-caliber 136 mm naval gun

Would a 72-caliber 136 mm naval gun be a useful fleet weapon?

It offers potential range and velocity, but barrel wear, mounting requirements, and incomplete performance data make the comparison uncertain.

The role-playing design concerns a 136 mm, 72-calibre Krupp gun, with the manufacturer corrected during the exchange. Its proposed role is initially surface fire. Barrel wear is the main objection, and powered mountings would be needed to make such a long weapon practical. Dragon considers a comparison with contemporary six-inch guns reasonable, while the other participants question equivalence. Complete performance data are unavailable, so the comparison uses contemporary 5.5-inch and six-inch weapons as reference points. A longer barrel offers potential muzzle velocity and range, while any penetration advantage also depends on shell design.
