The Gulnahan Ravine is a land area on Earth in the Cosmic Era timeline.


The Gulnahan Ravine is a strategic pass east of Suez, which is the only point in the area passable by large vehicles such as land battleships. The Earth Alliance created a fortification known as the Lohengrin Gate in the middle of the Gulnahan Ravine. This base was named for its primary armament, a "Lohengrin" Positron Blaster Cannon. This powerful weapon allowed the Lohengrin Gate to destroy any ZAFT forces that attempted to pass through the ravine. In addition, to protect the Lohengrin cannon, the Mobile Armor YMAG-X7F Gells-Ghe was stationed at the base. The Gells-Ghe's Positron Reflector shield was able to block any weapon in the ZAFT arsenal, even the battleship Minerva's "Tannhäuser" positron blaster cannon. However, the Minerva was contacted by Gulnahan native Conille Almeta, who informed them of a cave system in the ravine, unknown to Alliance forces. These caves allowed ZGMF-X56S Impulse pilot Shinn Asuka to bypass the Gells-Ghe and destroy the Lohengrin. ZGMF-X23S Saviour pilot Athrun Zala took advantage of the distraction presented by Shinn's assault to disable the Gells-Ghe in close-range combat, and allowed ZAFT engineers the opportunity to study its positron reflector to be used in the newly developed mobile suits.
