Tauberg
From Electrosphere
Tauberg is seen in Ace Combat Zero: The Belkan War. Tauberg is mostly flat, with the exception of some hills and steep valleys. To the north there sits the enormous wreckage of Excalibur - built during the Belkan War of 1995 to attack Allied aircraft. There are still some abandoned jamming facilities nestled among the hills.
[edit] The Belkan War - Operation
On May 15th, 1995, Excalibur was fired for the second known time at the Ustian Air Force, during Operation: Dynamo. Excalibur, located in Tauberg, was promptly moved to the top of the priority list of Allied Command. After suffering major losses in Operation Dynamo, a strike force composed of multiple fighters from the allied nations, was sent to attack the Excalibur on May 23. Including the 66th AFU 'Galm' and 4th AFU 'Crow' Team of the Ustian 6th Air Division, the strike package managed to get within close range of Excalibur, but were quickly fired upon by the Excalibur and jammed by it's defenses.
Within minutes the jammers were destroyed by Galm One of the Galm Team and the Excalibur was attacked directly, as it continued to fire it's main laser directly at the incoming aircraft. While flying within the Excalibur the allied aircraft were engaged by smaller RTLS Laser Cannons as well. Eventually, the Excalibur was stripped of all defenses, it's main laser was disabled and the Excalibur was completely destroyed.This was all accomplished by Galm One. During the celebration that quickly followed, the Excalibur broke in half and fell to the ground.
