• Light weight and stable armament platform for light aircraft

  • Rapid reconfiguration without tools

  • Modular components

Overview

Built to meet the most stringent of US military requirements, CFD International’s Ordnance Mounting System (OMS) has been providing US troops protection in combat since 1987. Originally developed for the U.S. Army’s 160th Special Operations Aviation Regiment (SOAR) MD-500 “Little Bird” fleet, this patented, combat-proven system is now available in several configurations for greater versatility.

CFD’s innovative designs are intended to deliver maximum flexibility. Modularity of the OMS - combined with high-capacity ammunition magazines - allows for a variety of weapons configurations to suit a multitude of mission requirements.

Features & Benefits

  • Low Weight - supports 30 times its own weight, giving the customer more fuel and firepower.
  • Stiffness - constructed from materials with high specific stiffness, increasing armament stability to minimize dispersion.
  • Compatibility - with up to six store locations, the customer can equip the aircraft with 7.62 to 30mm machine guns, rockets and missiles.
  • Small Footprint - the outboard stores fold over on top of the center section, making the aircraft narrower for dense packing.
  • Rapid Reconfiguring - the system can be rapidly installed, reconfigured or removed
  • High Capacity Magazines - up to 3,000 rounds of 7.62mm or 600 rounds of .50 cal ammunition per magazine.
  • Troop Carrying Capability - one variant of the OMS provides troop carrying seats on both sides of the aircraft. Each bench can carry three people or one litter.
