Frequently Asked Questions

How does the 16-inch naval gun breech operate?

The 16-inch naval gun breech operates manually. An operator disengages a locking mechanism, allowing a heavy breech door to swing open. The breech block then rotates and withdraws, revealing the interrupted screw threads used to seal the gun's chamber for firing.

What is the significance of the interrupted screw threads on the 16-inch cannon breech?

Interrupted screw threads on the 16-inch cannon breech allow for rapid sealing and unsealing of the gun's chamber. Portions of the threads are removed, enabling the breech block to be quickly rotated and withdrawn for loading, crucial for maintaining a high rate of fire on naval vessels.

What is the approximate weight of a 16-inch naval gun breech mechanism?

The complete breech mechanism for a 16-inch naval gun weighs approximately 47,000 pounds. This substantial weight underscores the engineering challenges and the sheer power of the weaponry employed on US battleships.

What historical event is associated with the 16-inch cannon breech shown?

The 16-inch cannon breech featured in the video is associated with US Navy battleships present at Pearl Harbor during the attack on December 7th, 1941. It represents the powerful armament of that era.
