Israel's Soltam has provided the 120 mm recoil mortar system. Elbit System's U.S. subsidiary, EFW has provided a weapon control system and enhanced tactical computer.
The Israeli systems were integrated on a Supacat High Mobility Transport, meant to provide tactically maneuverable fire support and rotary wing or tiltrotor transportability.
Lockheed Martin successfully tested its Expeditionary Fire Support System (EFSS) engineering prototype at the 29 Palms test range in California. The EFSS was designed and built (on Lockheeds dollar) for the US Marine Corpss fire support requirement. During the tests the self-propelled 120 mm mortar system fired several rounds from various elevations and azimuths, including over-thecab shots. The EFSS integrates a Supacat High Mobility Transport vehicle, the Soltam 120 mm recoil mortar system and a weapon control system and Enhanced Tactical Computer from EFW.
