Caseless Ammunition Capability Demonstration Patricia M. O’Reilly Chief, Energetic and Organic Materials Laboratory Branch Energetics and Warheads Division Energetics, Warheads, and Environmental Technology Directorate Armaments Engineering and Technology Center US Army Armament Research Development Engineering Center NDIA Small Arms Symposium & Exhibition May 12, 2004 Las Vegas, Nevada
Caseless Ammunition Capability Demonstration Objective To develop and demonstrate an in-house capability and core competency to manufacture Caseless Ammunition prototypes in support of the Lightweight Machine Gun and Ammunition Science & Technology Objective Deliver Caseless Ammunition for a live-fire/ballistic demonstration Establish ARDEC with a World Class Caseless Ammunition Capability
Caseless Ammunition Capability Demonstration Why Caseless Ammunition? Lightweight Force Multiplier Decreased Logistics Burden High Ignition Temperature Propellant (HITP) provides improved propellant characteristics & energetic behavior High level interest Push the State of the Art – A Technology that fits the “clean slate” approach
Caseless Ammunition Capability Demonstration Background Previous work performed under Advanced Combat Rifle (ACR) Program nearly 15 years ago Technology Development funded by US (ARDEC) and Germany to Heckler & Koch (H&K)/Dynamit Nobel (DNAG) Successful Demonstration of Caseless Ammunition Rifle System Technology Licensed & Transferred to the US at ARDEC
Caseless Ammunition Capability Demonstration Why ARDEC In-house Effort? Original Caseless Ammunition prototype manufacturing capability exists/retained Risk of Technology being lost - Loss of expertise Develop and maintain expertise/competency area Provides new hires hands-on experience Development of cutting edge technology
Caseless Ammunition Capability Demonstration Technical Approach Determine Feasibility Identify and address technical challenges/potential risk areas Near term & long term Material needs and source suppliers - availability Assess equipment condition Costs Determined viability Organizational Commitment Re-establish capability and prototyping process utilizing existing technology Validation of In-house Caseless Ammunition capability for 5.56mm
Caseless Ammunition Capability Demonstration Status of Progress Accomplishments Materials, supplies and services obtained Maintenance and service equipment – test and manufacturing SOPs and Manufacturing Process procedures Baseline Formulation Selected First HITP mix manufactured Pressing Study completed
Caseless Ammunition Capability Demonstration
Caseless Ammunition Capability Demonstration Status of Progress Next Steps Select initial charge weights Manufacture initial quantity of prototypes Charge Weight Determination (Ballistic Evaluation) Evaluate results and select next charge weight(s) Characterization Implementation of any processing improvements Interior Ballistic Modeling Manufacture second HITP mix and qty of prototypes Charge weight(s) verification (Ballistic Evaluation) Evaluate results and determine optimal charge weight Manufacture HITP for Demonstration Quantity Small qty of prototypes for charge wt and ballistic performance validation Manufacture demonstration qty Deliver Demonstration quantity - June ‘04
Caseless Ammunition Capability Demonstration Technical Challenges Long term availability and identification of source suppliers Material replacements Environmentally friendly alternatives/ manufacturing processes for constituents Summary Validation of the in-house capability proceeding Efforts focused to bring Caseless Ammunition Capability/Technology to a sufficient maturation level Acknowledgements JSAAP Office PPP Entire Caseless Ammunition IPT
