Balaur

The Balaur was an large railgun operated by the terrorist organization Valahia in Ace Combat: Joint Assault.

Description
Two variants of the Balaur have been confirmed to exist: one mounted aboard the Valahia's combat aircraft Spiridus and a stand-alone variant.

Spiridus
The first Balaur was mounted in the midsection of the Spiridus' airframe. The weapon first saw action in battle during the Valahia's initial assault on the Japanese capital of Tokyo, where it was used to damage Tokyo Bay, thus demonstrating the Spiridus' combat capabilities.

The Spiridus contained a heat vent at the rear of the mainframe, which caused the Spiridus' Balaur's charging to destabilize, and potentially lead to damage from overloading. Antares Squadron used this weakness to deal severe damage to the Spiridus and forced it to retreat from Tokyo towards the Izu Islands where visual contact was lost.

Ground
A second, stand-alone version of the Balaur was stationed at the Valahia's headquarters in Southern Romania. The weapon fired with the assistance of a radar network disguised as a weather station in the Serbian mountains, thus increasing its accuracy over long ranges. It is possible that the Balaur may have had an intercontinental firing range, due to the distance between Southern Romania and Serbia.
