Combat Engineering has existed for almost as long as combat. As humans reached for the stars, the idea followed the along. The Helios-class was designed to support front line combat operations; it is able to jam enemy sensors, repair external damage and boost friendly shield levels.
The pictured version belongs to the Sinistral, an independent group of scientists and researchers who hire out their abilities and experience to the highest bidder. Their combat engineering vessels are hardy enough to survive encounters with an enemy force; the SS version features enhanced jamming capabilities as well as micro-mine launchers to destroy or disable pursuing craft.
