This paper model is an Agro Ship, the common classification for spacecraft capable of growing any edible agro foodstuffs needed in a convoy or Fleet for long periods of time, based on the American military sci-fi television series Battlestar Galactica, the papercraft was created by Steve.
Agro Ships have translucent hull plates interconnected in a structural enforcement grid, which allow the plants to receive the necessary sunlight from a nearby star or some other stellar formation to achieve the state of photosynthesis. Artificial lighting is, apparently, also an important function of these agro ships. One of the crops grown aboard the agro ships is the tallon plant.
Agro ships are unarmed, but can withstand an assault for some period of time. Battlestar Galactica's Fleet has three such agro ships; two of which are destroyed by the Cylons and the third, the Agro Ship 9, experiences a hull breach via a destroyed airlock. Count Iblis also visits the Agro Ship 9 with Lieutenant Sheba during his time with the Fleet. [Source: BS Wiki]
