  1. ARDEC, Picatinny Arsenal 16 & 17 July 2012 Constrained Layer Dampening Barrel technology

  2. Summary • Radial Mean Dispersion improved ± 48% • σ improved even more • Demonstrated to 500 meters • No noticeable degradation over 1,700 rounds • Tested: 5.56, 30.06, 308, 338 Lapua. . . . • Dreadnought™ rifles consistently show similar R.M.D. {0.61±0.02 M.O.A.}

  3. Summary – Kolmogorov-Smirnov 83.8% probability base rifles dissimilar 100.0% probability Dreadnought™ caused accuracy improvement 99.5% probability Dreadnought™ B and C Rifles dispersion identical 100% probability Dreadnought™ affected muzzle velocity

  4. Summary – 338 Lapua Wander

  5. Summary – Super Dreadnought™ • High-loss acoustic waveguide • No weight penalty – soldier proof • 20% R.M.D. improvement over Dreadnought™ • More complicated computer model • Can the physics be simulated?

  6. Summary – Acoustic Analysis

  7. Elastomeric Material Characterization • Sample delivery • Shrinkage example {~summer 2010} • Environmental sample {July 2010} • 3 Alternate materials: drop test • Loctite FAILED • Epoxy.com #964 SUCCESSFUL • EAR Specialty Composites ?

  8. Modeling Considerations • Dreadnought™ or Super Dreadnought™? • Existing prototype or new weapon? • Dreadnought™: 5.56 (1); 308(2+1); 30.06 (1) • Super Dreadnought™: 338 Lapua (1+1) • Field test by Auto Bolt or ARDEC or both? • Caliber? • Ammunition loading and by whom? • Range?

  9. Classification Question No commercial activity being pursued currently. Can classification issue be resolved? If classified, can CRADA be modified?

  10. Patents Dreadnought™ patent status Pursuit of Super Dreadnought™
