x-wing

The X-wing starfighter is a name applied to a family of fictional spacecraft manufactured by the Incom Corporation from the Star Wars franchise. Named for the distinctive shape made when its s-foils (wings) are in attack position, the X-wing was a class of starfighter used by the Rebel Alliance in their conflict with the Galactic Empire. It made its theatrical debut, as the T-65B model, in Star Wars (1977) as the spacecraft piloted by Luke Skywalker and the Red Squadron when Luke destroyed the Death Star. The starfighter featured extensively in the Star Wars original trilogy and in the Expanded Universe that followed, and has been merchandised as a variety of toys and models. Starting with The Force Awakens (2015), a new model of X-wing was introduced, which has gone on to play a prominent role in the Star Wars sequel trilogy. The T-70 X-wing, flown by the Resistance in their fight against the First Order, is depicted as the successor to the T-65. Although described as being an improvement over the original, in the expanded literature this new X-wing is itself considered outdated, having been replaced by the T-85 X-wing in the New Republic's defense fleet. The T-85 X-wing made its first appearance in the TV series Star Wars Resistance (2018).
