• External mount and magazine frees up cabin space

  • 14-inch NATO bomb rack store for rockets or missiles (option)

  • .50 cal and 7.62mm weapons


CFD’s External Gun Mount System (EGMS) has assisted U.S. Air Force CSAR Pave Hawk personnel to save lives since 2003.

The system is stiff to yield low dispersion and get rounds on target. Reliability has continuously improved through years of field trials and design iterations. EGMS requires minimal maintenance.

EGMS is compatible with our quick-release External Store System (ESS) for rockets, APKWS, HELLFIRE, fixed-forward large caliber weapons or most anything that can be mounted on a standard 14-inch NATO bomb rack.

Features & Benefits

  • External Weapon Mount and Ammo - the tactical tow plate - installed outside the body of the aircraft - allows the ability to mount both ammunition magazines and armament external to the cabin. This design provides added safety in the event of a mishap, frees up valuable internal cabin space, and allows the crew chief/gunner windows to be closed in inclement conditions.
  • Rapid Reconfiguring - quickly change from .50 cal to 7.62 mm and back again, giving the mission commander maximum flexibility.
  • Fixed-Forward Fire - EGMS can be fired by the pilot in fixed-forward mode, or crew-served by a gunner.
  • .50 cal Weapon Compatibility - provides for a greatly increased Weapon Engagement Zone (WEZ), thereby eliminating the WEZ gap while simultaneously increasing lethal reach well beyond 1,500 meters (up to 3x minigun range) providing a defensive capability against light armored vehicles, weapons emplacements and structures.
  • High Capacity Magazines - up to 6,000 rounds of 7.62mm or 1,200 rounds of .50 cal ammunition.
  • Optional 14-inch NATO Bomb Rack Compatible Store - provides additional firepower without sacrificing significant field-of-fire as with an auxiliary armament wing.
