The E-2 Asteroid Miner served as a mining vessel for extracting resources from asteroids during the era of 3999 BBY.
Marauder Starjacker schematics. These vehicles, characterized by their insect-like design, were a widespread sight across the galaxy because they presented a more economical option compared to employing tractor beams for asteroid retrieval. It was a known fact that pirates utilized E-2s.
E-2 Asteroid Miners featured robust claws, enabling them to firmly grip the solid, rocky exterior of an asteroid, along with plasma drills designed for penetrating the asteroid's surface. Furthermore, E-2s incorporated thruster jets, facilitating the transportation of asteroids to designated mining sites. A centrally located suction tube facilitated the extraction of materials, channeling them into the vehicle's filtration system, where valuable ores were subsequently stored within cargo compartments.
