Cubicle fighters are special small fighter craft designed to be stored in standardized small craft cubicles, often mounted within a larger ship or station. The Planetary League Cubicle Fighter depicted in the illustration was a standardized design, mas-produced by a number of manufacturers throughout Era-1.
These inexpensive craft were widely used by most Planetary League agencies as light defensive fighters. There was also a very active private surplus market for these craft, and a wide array of variants, including many re-purposed versions were widely available.
The Planetary League standard cubicle fighter was designed solely for use in space. Having no landing gear, it could only depart or dock at a standardized craft cubicle. These cubicles were used for a number of small craft, including the also widely used Cubicle Shuttle, a sister craft produced by the same government programs and private manufacturers as the fighter. Docking and deployment was facilitated by robotic arms, and the pylons that connected the main guns to the fuselage had built in grip points for this system.
