Frequently Asked Questions

What is the primary function of the semi-automatic breech on the Bethlehem Steel 37mm Cannon?

The semi-automatic breech on the Bethlehem Steel 37mm Cannon automatically ejects the spent cartridge case after firing and locks the breech open, preparing the weapon for the next round and simplifying the reloading process for the operator.

How does the Bethlehem Steel 37mm Cannon manage recoil?

Recoil management is achieved through a combination of an oil-filled hydraulic cylinder and springs. This system absorbs the energy of the firing impulse, reducing the force transmitted to the mount and operator.

What is unique about the mounting system of the Bethlehem Steel 37mm Cannon?

The Bethlehem Steel 37mm Cannon features a free traverse mount. This design allows the operator to aim the weapon by using their shoulder for adjustments, a method more commonly found on naval guns than typical field artillery pieces.

What historical context surrounds the Bethlehem Steel 37mm Cannon?

Manufactured in 1916-1917, this WWI-era cannon was initially ordered by France. However, the US Army seized the remaining order, and the guns remained in US inventory until 1921 without seeing combat service.
