The Naval Surface Warface Center’s Crane Division has invented a polymer insert that internally retrofits ammunition with a flash corridor, allowing the primer’s spark to move into the center of the cartridge before igniting the propellant.
The invention creates a non-traditional burn pattern with advantageous effects.
The patent-pending technology is available via license agreement to companies that would make, use, or sell it commercially.
- Improves ammunition performance
- Less propellant is pushed into the firing chamber and barrel, reducing carbon buildup
- Polymer inserts are cheap, easy to manufacture
- Can be used to modify and improve traditional brass or polymer cartridges
- Businesses can commercialize the technology by licensing U.S. Patent App. 16/429,912 from the Navy
- License fees paid to the Navy are negotiable
- TechLink guides businesses through evaluation and licensing; services provided at no cost
