The AR-25 transport vessel functioned as a ship utilized by the Daedalus Gas Mines Corporation in support of gas mining operations on planetary bodies such as Genarius. This mid-sized transport craft, frequently referred to as a "Bubbleship" or "Bubblecraft," featured a distinctive characteristic: a thick-walled, transparent bubble serving as its cargo hold, allowing for the visual inspection of contained gases. It was possible to observe, and measure the excitation levels of the gases.
Erd Lumas held the position of an AR-25 pilot around the time of 32 BBY.
