This paper model is a Nial Class Heavy Fighter, the primary fighter of the Minbari Federation from the American space opera television series Babylon 5, the papercraft was created by Diego Cortes Pardo. The Nial Class Heavy Fighter was manufactured at the Valeria-On-High Orbital Shipyards over Minbar.
The Nial is the most powerful fighter in the younger races' arsenal. It sports an array of advanced systems, incredible firepower and manoeuvrability. Armament consists of three light neutron fusion cannons, similar to those found on a Sharlin class warcruiser but much less powerful.
Defenses include a Minbari stealth system, making a weapons lock impossible for most other races. While in flight, the pilot operates the ship in the prone position. Due to the fact that the ship is designed primarily for hit-and-run attacks, it carries only a limited air supply and has no jump capability of its own.
Having proven to be a dependable design for over a thousand years, the Nial has served in both the First and Second Shadow War, the Earth-Minbari War and continues to serve in the fleets of both the Federation and the Interstellar Alliance, with a small contingent of Nials normally stationed aboard the Anla'Shok's Whitestar fleet.
