PICATINNY ARSENAL, N.J. (April 23, 2015) -- In certain battlefield conditions, such as the mountainous terrain and unimproved roads of Afghanistan, large-caliber indirect-fire weapon systems lack the mobility and maneuverability required to successfully execute an assault.
To resolve this concern, engineers at Picatinny Arsenal are developing a revolutionary weapon system called the Automated Direct Indirect-fire Mortar (ADIM), which can be fired while mounted on a light tactical vehicle such as the HMMWV (High Mobility Multipurpose Wheeled Vehicle) or its replacement.
The ADIM, currently an 81mm mortar weapon system, uses "soft recoil" to reduce the firing loads transmitted to the platform by a factor of eight, well within the limits of the HMMWV (or other light tactical vehicles) capacity. This enables mounted firing and supports rapid mobile operations.
An associated benefit of the soft recoil system is the ability to fire the weapon (direct) at low quadrant elevations (QE) as well as (indirect) at high QE to either compensate for terrain interferences or take advantage of the reduced time of flight associated with low QE firing solutions.
