Rogue One: A Star Wars Story will introduce two new starfighters and a new Imperial Walker into Star Wars canon in what seemed like a ploy to sell a new round of toys this Christmas but now, thanks to Entertainment Weekly, we have an understanding as to why the new Tie Striker sports a more aerodynamic set of wings as opposed to the wings of the traditional Tie Fighter.
The Tie Strikers aerodynamic wings allow for pilots to maneuver the starfighter much better within a planet’s atmosphere than it’s predecessor. Having improved maneuvering capabilities allows for a more effective line of defense when protecting Imperial bases such as the one that is host to the Death Star manufacturing facility on Scariff which is exactly where we will see the Tie Strikers in Rogue One.
Wookiepedia also has the description as well.
The TIE Striker was a streamlined variant of the TIE line starfightersused by the Galactic Empire for in-atmosphere engagements and the defense of important Imperial bases. Though designed for atmosphere, it could also function in space and accompany traditional TIE fighters.[3] Equipped with advanced high-speed wings, it was faster than the standard TIE/LN starfighter and had an extra pair of laser barrels.[1][4]
Head on over to EW to check out the full video explaining the features and benefits of the Tie Striker.
