An interrupted-thread breech belongs to the screw-breech family

The follow-up clarifies the breech terminology used for the proposed 21-inch naval guns.

Question

Does the proposed screw breech mean an interrupted-thread breech?

Short answer

Yes. The interrupted-thread mechanism is treated as a development within the screw-breech family, distinct from a sliding breech.

Notes

The earlier recommendation for a screw breech is confirmed to mean an interrupted-thread design. The explanation places that mechanism within the screw-breech family because it developed from that approach. A sliding breech is identified as a different system. No detailed mechanism or loading-cycle comparison is given.
