Frequently Asked Questions

What is a WW2 Mark 29 3"/50 caliber round?

The WW2 Mark 29 3"/50 caliber round is a naval artillery ammunition type used by the U.S. Navy. It features an Armor Piercing Capped (APC) projectile designed for penetrating armor and utilizes flashless propellant with a percussion primer.

What are the key components of the Mark 29 3"/50cal APC round?

The key components demonstrated are the projectile body, a yellow-tipped armor-piercing cap screwed onto the projectile, and a brass casing marked 'FLASHLESS' and 'PERCUSSION PRIMER' with a headstamp indicating its caliber and year of manufacture (e.g., 1945).

What does the headstamp on the casing signify?

The casing headstamp, such as 'ALN PH-27-S1-45, 3 IN 50 CAL, 8056, SPDN', provides crucial manufacturing details. It typically indicates the manufacturer (ALN), primer type (PH), lot number (27-S1), year of production (45), caliber (3 IN 50 CAL), and other production identifiers.

Why was flashless propellant used in naval ammunition?

Flashless propellant was used to minimize muzzle flash, which enhances the concealment of naval vessels during combat operations and reduces the risk of igniting nearby flammable materials, thereby improving safety and tactical effectiveness.
