Description
25mm Experimental “Short” Round from General Dynamics Ballistics Laboratory
Item Overview
This experimental 25mm “Short” round is attributed to the General Dynamics Ballistics Laboratory. It represents the research and development work used to evaluate new medium-caliber ammunition before production or military acceptance. Its unusual compact configuration makes it an interesting artifact from the testing stage of ammunition development.

Experimental Laboratory Role
Ballistics laboratories produced test cartridges while developing new projectiles, cartridge cases, propellants, and weapon systems. Experimental rounds could support dimensional checks, feeding trials, chamber testing, pressure evaluation, velocity studies, or projectile-development work. Without its original laboratory records, the exact purpose of this example cannot be confirmed.
“Short” Configuration
The word “Short” describes this round’s compact configuration but has not been verified as a formal military designation. General Dynamics worked with several different 25mm cartridge families, including automatic-cannon and grenade-system ammunition. This example should not be identified as 25×40mm, 25×59mm, 25×137mm, or another standardized cartridge without supporting dimensions or markings.
Historical Background
General Dynamics became a major developer and supplier of medium-caliber weapons and ammunition for ground, naval, and aircraft applications. Its development process included concept design, laboratory testing, qualification, production, and demilitarization. Experimental specimens preserve an early stage of that process and may differ greatly from the standardized cartridges that later entered service.
Condition
This experimental military-surplus item may show scratches, finish wear, discoloration, oxidation, machining marks, laboratory handling marks, or other signs of age and testing. Its exact date, material, internal construction, loading status, and test purpose have not been confirmed. This listing is for the experimental round only; test fixtures, laboratory records, packaging, weapons, and other components are not included unless specifically pictured or stated.
Ideal For
This experimental round is well suited for General Dynamics collections, ammunition-development displays, ballistics research exhibits, military museums, ordnance identification collections, and advanced medium-caliber ammunition study.
