40mm Reliability Trends in the

System Contract

NDIA Small Arms Forum

June 2, 2015

Presented by: Matt Eckel


Premise

The high reliability of the US Army’s ARDEC

designed 40mm fuzes and tactical cartridges

has been demonstrated through 10 years of

two Systems Contracts.

From Break-out to System Contract

In 2005, the US Army awarded the largest

ever Small Business Set-Aside System

Contract. The new Prime Contractor

assumed responsibility for overall 40mm

cartridge reliability results.

Bottom Line Up Front

• Implementation of System Management

Contract has confirmed 40mm System

Capability and Warfighter Utility


Bottom Line Up Front

• Performance – Repeatability and

Reliability Exceeding Requirements

• Availability – Production Rate and

Schedule Meets US Army Needs


Reliability

Two Types of Reliability:

Functional

High Order Main Charge Detonation

Safety

It detonates when it supposed to, safe to

handle, and compliant to MIL-STD-1316

Reliability Contributors

Contributors to High Reliability:

• 10+ years of Contractor “Lessons Learned“

• Increased Automation

• Robust Inspection Criteria

• Variability Reduction



Contractor “Lessons Learned“

• Process Improvements have occurred at

all levels from component manufacturing

to Cartridge LAP

• Inspection and Sampling

• Integrated Product Team (IPT)

• Engineering Change Proposals (ECP)



Contractor “Lessons Learned“

• Fuze Modeling Addressed Stack-up

Tolerance Issues

• Capitalization Improvements in Assembly

Equipment Capabilities



Increased Use of

Automation

• Sensors

• Auto Recognition

cameras

• Digital X-Ray

• Robots

• Networking



Inspection Criteria

• Critical Characteristics Control Plans

• Automatic Acceptance Inspection

Equipment (AAIE)



Variability Reduction

• The System Contractor and suppliers have

imposed tighter tolerances than allowed in

the TDP based on analysis of key

characteristics that drive variability

• Charge Evaluation Charge Verification

(CECV) & Automated Propellant Loading


Benefits Realized

Program:

• Repeatability and Reliability Demonstrated

to exceed Requirements

• Subject Matter Expertise (SME’s)

Strengthened

• Production Continuity through Single Fuze

Manufacturer

• Mature Supply Chain Management


Benefits Realized

Warfighter:

• Ammunition Available – Inventory

Established

• Performance Repeatability

• Operational Safety

• Weapon Interface –Stoppage/Jam Risk

Minimized

• CONFIDENCE IN 40MM


Conclusion

Under the current management teams of the

U.S. Army Product Director for Medium

Caliber Ammunition, ARDEC, and the System

Prime Contractor, the fuze safety, arming,

and functional reliability characteristics of the

40mm fuzes and their integration with the

high explosive cartridges have been

demonstrated to exceed the published

military specification requirements.
