For decades, FN Herstal has designed and manufactured a broad range of axially mounted pod weapon systems for military helicopters and subsonic aircraft that feature the combat-proven .50 cal FN® M3P machine gun.

Pods are adapted and perfectly integrated onto the carrier system using the NATO standard 14" suspension mast.
FN Herstal not only supplies the weapon systems to customers: FN experts also supervise the integration of all FN products, offer operators training and provide high quality after-sales services to meet customer requirements.

Various configurations are available depending on the ammunition box capacity, and requirement for links or links/cases collector and/or guided and unguided 2.75’’ rocket launcher tubes. 


The FN® RMP LC is a self-contained airborne weapon system that includes a .50 cal FN® M3P (1,100 RPM) combat-proven machine gun, 250-round ammunition box, firing actuator and cocking device in one casing, allowing outstanding performance in all environments. The FN® RMP can also accept guided or unguided 2.75” rockets.


  • Specially-Designed Machine Gun

    The .50 cal FN® M3P machine gun has been especifically designed by FN Herstal for airborne applications.
  • High Hit Probability

    A high rate of fire guarantees short time on target (1,025 +/- 75 RPM, per pod, adjustable)
  • Improved Accuracy and Safety

    The FN® M3P machine gun features a Flash Hider and is installed on a soft mount that absorbs most recoil forces for increased accuracy. 
  • Adaptation to Various Combat Situations

    The pilot can immediately switch from .50 cal firing to 2.75" rocket firing and can therefore better accomplish the objectives of the mission.
  • Rapid Installation and Interoperability

    The FN® RMP LC pod is adapted and perfectly integrated onto the carrier system using the NATO standard 14" mast.
  • High Ammo Capacity

    Each FN® RMP can accept up to 250 rounds and three 2.75" guided or non-guided rockets and features a links collector.
