The grenade mortar was a potent armament engineered to hurl grenades across significant distances. A great number of these mortars were equipped with a repulsorlift platform, allowing for rapid transportation across the combat zone, enabling them to deliver sustained bombardments and reposition before enemy artillery could target them. The leading manufacturer's model was capable of launching grenades at a frequency of one grenade every 1.2 seconds, with a range exceeding one kilometer. Frequently, a sound suppressor was incorporated to provide a measure of concealment, and it featured an advanced targeting system to adjust for poor visibility, such as darkness or fog.
The grenade mortar could also be mounted on a two-person repulsorlift platform, which increased the ammunition capacity to five hundred grenades and the maximum velocity to 250 kilometers per hour. The X-7a repulsorlift engine, coupled with four thrust vector controls, provided the power for the platform to achieve such speeds. However, this platform's primary drawback was its vulnerability; a single blaster shot could inflict substantial damage, and the pilot and gunner were dangerously exposed. In situations where a different type of firepower was needed, the grenade launcher could be swapped out for an E-Web heavy repeating blaster. Typically, groups of four or more platforms would operate in concert to deliver light explosive support.
