The technology demonstrators were presented by Lockheed Martin at the Human-Machine Integration Summit of the 4th U.S. Army. The vehicle is distinguished by its firepower and dimensions, not only by its "compact" (because it can be met by air in the C-130 Hercules aircraft hold) of the M142 HIMARS kit, but besides by its equipment with larger dimensions, specified as M270 MLRS or K239 Chunmoo launchers (and its Polish cousin Homar-K).
