Produced by Ubrikkian Industries, the HAVr A9 Floating Fortress was a 17.4 meters roughly cylindrical, heavily armored repulsorlift combat vehicle. Capable of reaching speeds of two hundred kilometers an hour, with a maximum flight ceiling of twenty meters, the Floating Fortress was able to both avoid or go through most obstacles in its way.
The Floating Fortress mounted a twin turret blaster cannon on its roof comprised of two Mk 2e/W heavy blaster cannons, with each cannon capable of moving and tracking targets independently. At night, powerful search beams swept for targets before the blaster cannons locked on and fired.
A sophisticated audio-visual surveillance system was installed on the Floating Fortress, which combined listening devices and heat sensing probes to create a sensor bubble with a thirty-meter diameter. The resulting Target Identification Network could detect nearby enemies. The system was based off a sensor package employed by assassin droids. The TIN could also be used to target a single enemy for a surgical strike when a show of power was required that did not need wanton destruction.
Floating Fortresses required a crew of four; a pilot, a sensor operator for the Target Identification Network, and two gunners. There was room for ten soldiers to be carried aboard, as well as one metric ton of cargo.
The Floating Fortress gained a reputation for being a thorough, merciless vehicle in use by the Imperial Army. Often deployed to combat uprisings in urban areas, entire cities could be devastated by a squad of Floating Fortresses in search of elements of the Alliance to Restore the Republic or other enemies. Unlike the All Terrain Armored Transport, the Floating Fortress was capable of traversing the narrow streets of an urban environment, and still generated the fear and respect that its walker counterpart did. This led to a rivalry between the crews of Floating Fortresses and All Terrain Armored Transports. Army Command preferred deploying the walker in combat situations, while the commanders of the occupation forces preferred to utilize the Floating Fortress.
During the early years of the Galactic Empire, General Hurst Romodi gained a reputation for leading battles from the open hatch of a Floating Fortress. The prestigious Raithal Academy utilized the Floating Fortress, among other vehicles, to train Imperial Army cadets.
The Katarn Commandos freed two New Republic prisoners from a Floating Fortress on Hettsk around 9 ABY. Several Floating Fortresses were also used by the Imperial Remnant in the attack on the Jedi Praxeum in 12 ABY.
