AE20-VM2 Vehicle Weapon Mount

The AE20-VM2 Vehicle Weapon Mount is a lightweight, Aluminium mount for the 20 mm AEI-HS804 gun. The mount accepts AEI’s RH & LH drum belt feed mechanisms and flexi-chute for prolonged target engagements.

The mount also accepts AEI’s lower profile ‘flat’ belt feed mechanism and can simply revert to receive AEI’s linkless feed drum magazine associated with the AE20-NM naval mount. The cradle is spring-loaded to assist the operator to engage elevated targets and balance the gun horizontally whilst vehicle trundling.

The weapon mount can be readily fitted to the vehicle slewing ring, roof, bulkhead or pedestal. The ammunition feed tank can be mounted to suit individual vehicle installations and linked to the mount with AEI’s flexi-chute.

Recoil management is a critical factor in maintaining accuracy and operational stability. The AE20-VM2 excels in this area with its sophisticated recoil system. The cannon’s maximum recoil force is 4.5 kN (1,012 lbf), while the mean recoil force is maintained at a manageable 1.6 kN (360 lbf). This advanced recoil mechanism ensures that the vehicle remains stable during firing, allowing for rapid follow-up shots and sustained engagement without compromising accuracy or control.

The cradle of the AE20-VM2 is sprung loaded, assisting the operator in engaging elevated targets and balancing the gun horizontally while the vehicle is in motion. This feature enhances operational flexibility and accuracy, allowing for smooth target acquisition and tracking.

The AE20-VM2 embodies cutting-edge design and engineering, incorporating the latest advancements in materials and technology. Its construction is not only durable but also designed to facilitate ease of maintenance and operation in the field. This ensures minimal downtime and maximum operational readiness, critical factors in high-stakes military operations.
