Helemmo Sonic Arms Company

The Helemmo Sonic Arms Company was a weapons manufacturer and a subsidiary of BlasTech Industries that produced various sonic weapons, including the Sonic Scout 1-M hand blaster wielded by some officers of the Imperial Army. The company was founded by Zodto Helemmo, a Coruscanti celebrity scientist who was notoriously fascinated with sonic energy, and was killed in a bombing while attending a science convention in his home neighborhood by a Separatist-funded terror cell months before the Clone Wars.

Researchers from the Helemmo Sonic Arms Company were stationed at an Imperial research facility on an icy dwarf planet in the Mid Rim, where they worked on a prototype ultrasonic bomb, which was eventually detonated on-site by a team of Mandalorian infiltrators that killed all in the facility.
