The F-11ABA heavy blaster cannon was a weapon employed by the Sith Eternal's Sith Jetpack Troopers within their army and fleet.
This blaster rifle, designated the F-11ABA, was a lethal weapon. It incorporated an amplifier barrel to generate a potent explosive projectile. Deployed on Exegol by Sith jet troopers, it represented an advancement over the First Order's standard F-11D blaster rifle. The weapon came equipped with an adaptable J20 electroscope that relayed information from the scope directly to the user's helmet, thereby enhancing both precision and situational awareness on the battlefield.
Sith jet troopers utilized the F-11ABA on Exegol in an attempt to hold back Resistance forces. These forces were launching an assault on the Resurgent-class Star Destroyer Steadfast with the goal of preventing the Sith Eternal's fleet, known as the Final Order, from escaping the system. Despite the defense ultimately failing, the F-11ABA, as used by the highly skilled jet troopers, proved to be a very effective weapon against the attacking Resistance troopers, causing significant casualties.
The F-11ABA made its debut appearance in Star Wars:E Episode IX The Rise of Skywalker. Its official designation as the F-11ABA heavy blaster cannon was later confirmed in Star Wars: The Rise of Skywalker: The Visual Dictionary.
