This paper model is a Scarlet Viper (Scarlet-class Viper), a fighter / attack craft from the sci-fi TV series BattleStar Galactica, the papercraft was created by Aaron Murphy. There are also two Viper Mark II Paper Models on the site.
The Scarlet Viper is introduced in Hatch's first novel, "Armageddon". It is said to be a successor to the Azure-class Viper, itself a successor of the original Viper seen in the Original Series.
The difference between this and the original Viper include a scanner that creates a "laser-constructed three-dimensional image" of destinations, in addition to improved systems and weapons, and even energy shields. However, these energy shields are incapable of handling a direct blast, at least without damaging the Viper, but can "shrug off" tangential blasts.
In creating his mock trailer for his continuation project, Battlestar Galactica: The Second Coming, Original Series actor Richard Hatch created an upgraded Viper for the project. The design for the fighter was inspired by the X-29 test fighter's swept forward wings. [Source: BattleStar Wiki]
