The Deep Space Miners' Alliance began in SC0064 as a sort of mutual protection pact between a trio of small mining companies--the experienced Ironwing Harvesters, the technologically adept Nu-Titania Diggers, and the family-owned but well-connected Nordstar Co., to be exact. Having each suffered greatly from deadly pirate raids and outright starjacking incidents in recent years, the three companies decided to pool their respective strengths and resources into a single overarching entity in order to stave off both bankruptcy and death--not that there was much difference between the two on the wild frontier of interplanetary industry and exploration, far from the eyes of authority.
Combining the technological skill and piloting experience of the Harvesters and the Diggers with Nordstar's connections in the Sol system, the miners were able to obtain "obsolete" military hardware that would've otherwise been scrapped, upgrading said equipment to modern specifications and mounting it on their ships to defend themselves in future skirmishes. While by cutting-edge military standards their weapons were relatively crude, they served well in the first subsequent clashes with outlaws, and many times thereafter.
Pictured are two of the most common fighter designs seen in DSMA colors.

The RM-E01
Remora fighter was built off of one of the M-1
Manta light mining craft owned and operated by the former Ironwing Harvesters. With the original design's bulky mining equipment and ore container pods removed, Nu-Titania's engineers were able to install additional combat-grade armor plating, high-output afterburners, and a pair of fire-linked D-26 "Thumper" autocannons, one mounted upon each of the ship's "fins". During mining operations, at least one
Remora will typically be assigned to each pair of DSMA mining vessels or freighters to act as an escort. In combat, they form the bulk of the Deep Space Miners' forces, acting as surprisingly durable and agile interceptors, picking off stragglers or defending vulnerable allies.

The HSP-2
Hopper is not, technically, a fighter craft per se, but it can give support to actual combat ships wherever needed. A support vessel by nature, it mounts a pair of high-powered sensor antennae above the cockpit to give an unparalleled view of the battlefield and leaving enemies with no place to hide from its companions. It also mounts the same type of high-output afterburners as the
Remora, allowing for excellent overall top seed as well as agility. While not designed for protracted engagements, it does mount hardpoints for three tactical torpedoes. This allows it either a decent amount of longevity when forced to fight, as well as making it a deadly hit-and-run vessel should the pilot choose to expend multiple torpedoes in a single salvo.
