25mm Anti-Material Payload Rifle

(AMPR-XM109)Facts & Claims

Facts

• A known commodity: The Barrett M107 is combat proven and Userrespected—the XM109 possesses much of the same architecture asthe M107

• Ammunition Availability: The 25mm XM109 will use the self-same

25mm armor-piercing ammunition as the Objective Crew-ServedWeapon (XM307)

Claims

• The 25mm XM109 offers significantly greater lethality than the .50caliber XM107 against C4I SAR targets

– Near term: Penetration potential from optimizing warheadpromises over 1 ½ -inches of RHA at 1200 meters and beyond

– Long Term: Optimized AP ammunition offers 2 + inches of HHA

(AMPR-XM109)Battelle Weaponeering Study

• Summarized Results:Probability of TargetDefeat

– Big Bird Radar

• At 800 meters theXM109 required half asmany rounds as theXM107.

– BMP-3• At 800 meters the

XM107 required 2 timesmore rounds than the

XM109.

Next GenerationNext Generation

• 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
