These fighters also show up in Wing Commander: Armada.
In Wing Commander: Academy, Confed flight simulators featured these fighters. These Jrathek fighters were equipped with two photon cannons, two plasma bolts, two Friend or Foe missiles and two Dart Dumbfire missiles.
In Wing Commander: Armada, the actual Kilrathi Jrathek fighter that was produced and seen in 2669 had a weapon array that included two flux and photon cannons, a total of four energy weapons. Its missile payload included two Friend or Foe missiles and two Image recognition missiles. These Jratheks were much larger and had a heavier defense than the ones portrayed in Confed's flight simulators. They measured at thirty-five meters in length and could reach a maximum velocity of 595 km/s, making them a fast and deadly fighter for the Kilrathi. [Source: wikia]
