Lockheed Martin is developing an upgrade for the High Mobility Artillery Rocket System (HIMARS) that will significantly increase its combat effectiveness. The new “FLEX” variant will double the system’s current munition firing capacity. This enhancement allows for a greater volume of fire in a single engagement. Details of the upgrade were recently unveiled by the US defense contractor. The increased capacity is expected to provide a substantial advantage on the battlefield. No timeline for implementation or deployment was specified in the announcement. The upgrade focuses on maximizing the existing HIMARS platform rather than creating a new system.
