# Caseless Ammunition

Ammunition without metal cases, reducing weight and cost for military logistics
- Technology Readiness Level: 6/9
- Impact: 4/5
- Investment: 4/5
Caseless ammunition eliminates the brass cartridge case; propellant is bonded or formed around the projectile. Benefits: lighter and cheaper ammunition; simpler firearms design. Field tests and limited commercialization; Lightweight Small Arms Technologies research. Challenges include heat dissipation, moisture sensitivity, and reliability.
