TIE Advanced v1 (also simply known as the TIE Advanced) was an advanced prototype Imperial starfighter that made its debut appearance in the Disney XD series Star Wars Rebels. Manufactured by Sienar Fleet Systems, these particular TIE Fighters served as personal starfighters for the Empire's Inquisitors.
Fifteen years after the formation of the Galactic Empire, Imperial leaders unveiled Sienar Advanced Projects Laboratory's prototype for a new starfighter at the Capital City Empire Day parade on Lothal, the TIE Advanced v1. Designers drew inspiration from the Eta-2 Actis-class light interceptor flown by Galactic Republic pilots during the Clone Wars.
The v1's P-s5.2 twin ion engines and L-s9.1 laser cannons were more powerful than those found on a standard TIE Fighter. Sienar also outfitted the v1 with basic deflector shields, projectile launcher, and a full life-support system that enabled the pilot to operate the craft without a pressurized suit and helmet.
Sienar produced a small number of the TIE Advanced v1 prototype for the Inquisitors, an Imperial organization of force-sensitive Jedi hunters. Sienar Fleet Systems expected the Imperial Navy would want to begin mass production immedietly after test flights proved the TIE Advanced v1 was faster, more maneuverable, and far more lethal than the standard TIE/in fighter. But after a string of setbacks involving Rebel agents on Lothal, production of the TIE Advanced v1 was put on hold indefinetly.
- S-foils: Sienar designers incorporated S-foils, also known as Strike foils, into the v1's wings. During normal flight, they would be locked in a closed position that brought the wings' upper and lower edges close to the cockpit module. When engaged in combat, pilots unlocked and opened the wings S-foils into attack position. Sienar designed the folding wings to conserve space within the TIE Fighter hangers, and to give the v1 a top atmospheric speed of 1,600 kph.
- Solar-collectors: Unlike other TIE Fighters, the v1 only had solar collectors on the inside of its wings. Heavy armor plating covered the wings's outside surfaces. Although the v1's high-performance solar collectors gathered more energy per square millimeter than solar collectors on a standard TIE Fighter, the v1's total solar-collecting capability was comparatively less, but provided sufficient power for the v1's less energy-intesive systems, and kept the fighter fully charged in most field conditions.
- Projectile launcher: The projectile launcher's magazine on the v1 carried up to twenty missiles, and could also deliver sophisticated tracking devices, such as the Imperial XX-23-S-Thread Tracers, to targeted vessels.
- The TIE Advanced v1 shares a few similarities to the TIE Advanced x1.
- While the TIE Advanced v1 appears in the game Star Wars: Squadrons, it is non-playable.
