The FN Herstal deFNder™ Light is a product designed and manufactured by FN Herstal, a worldwide leader in small arms and ammunition for over a century. FN Herstal is the only weapon manufacturer on the market that offers the integration of its long-proven weapons onto a remotely operated weapon station. The light deFNder™ system is the first in a series of such designs and is easily mounted on vehicles or installed in a static position to protect sensitive sites such as embassies, military facilities, and secured border environments. When the mission requires bringing a high volume of accurate fire on target while keeping the weapon operator safe and secure, the mission calls for the new FN Herstal deFNder™ Light Weapon Station. Based on reliable and state-of-the-art technologies, the FN Herstal deFNder™ Light Remotely Operated Weapon Station has been designed to be used for self-defense missions when mounted onto a light, medium or heavy vehicles, perimeter defense missions (border control, protection of military compounds, official buildings, etc.).

FN Herstal is a world leader in small-caliber weapons, roots going back to 1889. FN Herstal guarantees the integration of its machine guns onto the deFNder™.

Technical Data

The deFNder™ Light FN Herstal is composed of two major subassemblies. The first one is the above deck, with an armament module, including a 7.62mm machine gun, sight module, ammunition box, mast with azimuth and elevation actuators, and slip ring. The second part is the below deck, with the operator's console, including a display for target visualization and engagement, and the control handle for aiming, firing and sight selection.
Weapon Systems
The deFNder™ Light soft recoil mount increases hit probability and can be configured for a variety of weapons including the Minimi 5.56, M249, MK 48, Minimi 7.62, M240 and MAG 7.62mm. Future designs will accommodate the M2 and MK 19 series of belt-fed automatic weapons. The FN Herstal deFNder™is based on a modular design. Sight module, ammunition box module and control handle are customer choice, designed, developed and qualified in accordance with MIL-STD-1472, 810, 461, 1275 and MIL-HDBK 217E, Stanag 4370. The FN Herstal deFNder™ fitted with a MINIMI 5.56 machine gun fully loaded weighs less than 80 kg and does not exceed 520mm in height in a basic configuration. The FN Herstal deFNder™ features a soft recoil mount that minimizes shocks and vibrations, hence guaranteeing a high hit probability rate and reduced collateral damage. The standard day sight provides Narrow and Wide Field of Views for standard NATO detection, recognition and identification of targets at high ranges. Various optional sights are available to enhance further target acquisition under all visibility conditions, as LLCCD sight or IR thermal sight.
Command and Control
Fire control and weapon management functions include single shot and adjustable length burst options, fired round counter and end-of-belt cut-off. The operator interface features a display console for target identification and engagement, along with a single handle that controls sight selection, aiming and firing. The FN Herstal deFNder™ is a very high modular weapons station that can be fitted with three different FN Herstal's infantry light and medium infantry machine guns, which can also be used as dismounted weapons. The machine guns can be the Minimi 5.56 x 45 mm (M249), Minimi 7.62 x 51 mm and MAG 7.62 x 51 mm (M240). The replacement of machine guns takes no longer than a few minutes, without a specific tool required and the weapon can be removed in less than 15 seconds for use as a dismounted weapon. The FN Herstal deFNder™ has a unique elevation angle of +80°. This wide elevation angle is particularly useful in urban warfare when the weapon operator has to engage targets located at the top of high buildings, and during peacekeeping operations where the FN Herstal deFNder™ shows a non-aggressive profile. The depression for the FN Herstal LRWS is -60°, this feature is very interesting when the deFNder™ is installed on observation towers, the weapon operator can engage targets standing or moving on the ground.
FN Herstal offers total protection to the weapon operator with its new deFNder™ Light Remote Weapons station, which can be easily mounted onto low payload vehicles or installed in a static position. The FN Herstal deFNder™ can be easily integrated into all types of low payload vehicles to fulfill various missions such as surveillance and observation (reconnaissance), self-defense, escort or checkpoint support. The FN Herstal deFNder™ can also be installed on observation towers or onto the roof of buildings to guarantee the protection of sensitive buildings, sites or areas, like embassies or government facilities, military compounds, prisons or for border control.
Optical sensors available for the FN Herstal deFNder™ include daylight wide and narrow-angle video, low-light CCD, infrared/thermal and laser rangefinders. A wide range of product support services is available (spare parts & tools management, repair, and overhaul, maintenance, technical assistance, training, manuals, configuration management, etc.). Optics and control handles are customer choices.
