  1. 25mm Anti-Material Payload Rifle (AMPR-XM109) 50TH ANNUAL NDIA SMALL ARMS SYMPOSIUM AND EXHIBITION Neil Lee U.S. Army ARDEC AMSRD-AAR-AEW-S(D) Bldg 65 Picatinny, NJ 07806-5000 (973) 724-6743 nelee@pica.army.mil Sergio Aponte U.S. Army ARDEC AMSRD-ARR-AEW-M (D); Bldg 7 Picatinny, NJ 07806-5000 (973) 724-3445 saponte@pica.army.mil Ralph Mazeski U.S. Army ARDEC AMSRD-AAR-AEM-I; Bldg 65 Picatinny, NJ 07806-5000 (973) 724-6453 rmazeski@pica.army.mil

  2. Briefing Agenda: • Neil Lee: • The IPT • Facts & Claims • The Barrett 25mm Rifle System • Project Schedule • Sergio Aponte: • Battelle Weaponeering Study • Niceville Armor Piercing Tech Demo • Technical Challenges • Recoil Mitigation • Ralph Mazeski • 25mm Ammunition & etc. • Questions

  3. IPT Arrangement Sponsor The U.S. Special Operations Command Neil Lee Sergio Aponte Steve Small, Ph.D. CPT Bowser USSOCOM Weapon Developer Ronnie Barrett Bob Gates Bob Galleazzi M107 PM Crew Served Weapons Cape Aero Space Charles Poff Recoil Mitigation Ammunition Issues AETC Ralph Mazeski Dennis Durkin Ammunition Developers GDOTS Matt Solverson Kaman Dayron Recoil Mitigation Gamma Tim Lindsay

  4. Facts & Claims Facts • A known commodity: The Barrett M107 is combat proven and User respected—the XM109 possesses much of the same architecture as the M107 • Ammunition Availability: The 25mm XM109 will use the self-same 25mm armor-piercing ammunition as the Objective Crew-Served Weapon (XM307) Claims • The 25mm XM109 offers significantly greater lethality than the .50 caliber XM107against C4I SAR targets • Near term: Penetration potential from optimizing warhead promises over 1 ½ -inches of RHA at 1200 meters and beyond • Long Term: Optimized AP ammunition offers 2 + inches of HHA

  5. XM107Baseline System

  6. SYSTEM CHARACTERISTICS • WEAPON SYSTEM HAS RAPID CONVERSION CAPABILITY FROM M107 TO XM109 • XM109 & M107 HAVE 70% COMMONALITY • MAJORITY OF REPLACEMENT PARTS ARE CURRENTLY IN SUPPLY SYSTEM • WEAPON SYSTEM IS 10 INCHES SHORTER THAN M107 • CAPABLE OF DEFEATING MOST LIGHT ARMOR AND MATERIEL TARGETS OUT TO 2000 METERS

  7. XM109 Prototype

  8. Project Schedule • Fragmentation Testing of Baseline Ammunition May ’04 • Limited Safety Release scheduled for August ’04 • 3 weapon systems delivered to APG • 1675 total rounds of AP and TP ammunition • Initial Delivery of XM1049 HEAP ammunition September ‘04 • User Assessment scheduled for October ’04 • 10 weapon systems delivered to SOCOM • 2000 total rounds AP and TP ammunition • User Assessment Report expected December ‘04

  9. Battelle Weaponeering Study • Summarized Results: Probability of Target Defeat • Big Bird Radar • At 800 meters the XM109 required half as many rounds as the XM107. • BMP-3 • At 800 meters the XM107 required 2 times more rounds than the XM109.

  10. Tech Demo – 19 June 2003 Set-up: • High Speed and normal speed video record of pre-demo and demo at both target (perpendicular) and weapon (side view) locations • 6 foot x 6 foot x 1 inch thick armor target at 207m (RHA) • All shots fired by remote operation • Location: • Niceville, Florida

  11. Training-Practice and Armor-Piercing Ammunition, and the Target Effects 19 June 2003 – Niceville, FLA.

  12. CARTRIDGE, 25 MILLIMETER: Target Practice (TP) XM1050 • 20,000 rounds built and fired to date • Mann barrel dispersion ~0.25 mils @ 200yards • System dispersion ~1.1 mils @ 1350 meters • Simple two piece projectile construction • Integral rotating band • Common cartridge case, primer and propellant

  13. Behind ArmorWitness Plate CARTRIDGE, 25 MILLIMETER: Armor Piercing, XM1049 • Off the shelf nose fuze with spitback • Advanced molybdenum shaped charge liner • Over 2 inches of armor penetration (Lab) • Flight tested to 963 Meters • Dispersion ~ 0.75 mils First Generation

  14. CARTRIDGE, 25 MILLIMETER: Armor Piercing, XM1049 • Improvements: • Remove nose fuze = greater penetration • Base fuze utilizes existing HE safe and arm • Reduced parasitic weight • Addition of self destruct feature • Provides basis for high explosive dual purpose (HEDP) airbursting capability Next Generation
