Introduction
GD-OTS Niceville Has Developed a Reactive Material (RM)-Based Neutralization Technology With Broad Application to High Explosives (HE) Neutralization Neutralizers Contain Non-Detonable, High Flame Temperature RM Fill No S&A Required, Unreacted Neutralizers Not Classified as Unexploded
Ordnance (UXO) or Explosive Remnants of War (ERW)

Application EOD/RSP’s For IM Compliant HE Fills Increased IM Compliance of High Explosive Fills
Increases The Difficulty of Explosive Ordnance Disposal and Render-Safe Procedures Reduced Shock, Impact, Friction, and Sympathetic
Reaction Sensitivity Result: Existing Procedures Have Reduced
Effectiveness All HE Fills Eventually Succumb to Thermal
Threat Thermal Decomposition, Leading to a Burn or
Deflagration
Fragment Impact
Fast Cook-Off
IED/Mine Defeat Desire for Low Collateral Damage Effects During Threat Defeat

RM Fill Material Selection
Selected Group of Candidate Materials From Supplier Base
Initial Studies Conducted: Initiation Mechanisms/Sensitivity Temperature Effects Output/Effects on Flake TNT Test Results Suggested Dual Material Solution:
One Material Easily Initiated, But Limited Effect on HE – Igniter Second Material Harder to Initiate, But Greatest Effect on HE – Sustainer
Very High Flame Temperature: ~ 4500 °F

RM Neutralizer Design
Scored Steel Body • Contains RM Payload &
Mechanical Ignition Mechanism
• Scoring Assists Body Rupture, Release of RM
Aluminum Brake Sleeve • Assists in Coupling
Neutralizer to Target
Aluminum Tail Fin • Provides Aero Stability
Low-Drag Steel Nose • Provides Target Penetration,
Minimal Velocity Loss and Stable Trajectory Through Water
Neutralizer Can Be Tailored to Defeat A Range of Targets and Engagements Multiple Materials, Thicknesses, Emplacements, etc.
Form Factor Can Easily be Adjusted for Integration Into Existing EOD Tools PAN Disrupter, .50-Cal De-Armer, etc.
