GAT-706S Deep Forbidden

The Deep Forbidden is a Mobile Suit Variation of the series Gundam SEED.

Combat Abilities
Weapons wise, the Deep Forbidden shares many similarities with its predecessor, the GAT-X255 Forbidden Blue, although some weapons were removed. The armament consists of a single phonon maser cannon, an energy weapon specifically designed for underwater mobile weapons, which is mounted on the backpack and only usable in close combat mode. Another ranged weapon of the suit are two supercavitating torpedo canister pods, which are mounted on the arms connecting the backpack with the shields. For close combat, the Deep Forbidden features four retractable close combat spikes, with two spikes mounted in each shield. As with the other weapons, these spikes are primarly used in close combat mode. The last weapon used by the suit is an optional trident.

Geschmeidig Panzer
As with the other suits derived from the original GAT-X252 Forbidden, the main special feature of the suit is its "Geschmeidig Panzer" energy deflection armor, which is mounted on the two shields of the suit. This system, as with the other suits derived from the Forbidden to be used underwater, is used to move through water and counteract water pressure. While the original Forbidden Blue had the disadvantage of being crushed in deep waters if the system failed, the Deep Forbidden features an additional reinforced titanium armor around the cockpit, granting the pilots survival if the Geschmeidig Panzer failed. This system feature is carried over to the later produced GAT-707E Forbidden Vortex.

Tail extension
Like the Forbidden Blue, the Deep Forbidden is equipped with a tail extension, which mounts an ultra-long-wave antenna and a towed sonar array, while the anchor installed on the Forbidden Blue was removed. These equipments grant the suit advanced sensor capabilities if used underwater.

History
In CE 71, the Earth Alliance fielded three new Gundam-type mobile suits, which features improved technology compared to the five original suits created as part of the G Project. One of the was the Forbidden, which was designed for close combat and equipped with a "Geschmeidig Panzer" energy deflection armor to deflect incoming beam attacks. Since this system was ideal for use underwater as a propulsion system, a new series of underwater mobile suits was created by the EA to counter ZAFT's underwater mobile suits. The first of these suits was the prototype GAT-X255 Forbidden Blue, which featured armament designed mainly for underwater combat, among them phonon maser cannons. Eventually the suit was redesigned and put into mass production in form of the Deep Forbidden, which features similar but stripped-down armament as the prototype unit as well as improved technology. As with the prototype the Deep Forbidden was piloted by underwater ace pilot Jane Houston. Eventually the Deep Forbidden is succeeded by the GAT-707E Forbidden Vortex, which more closely resembles the Forbidden Blue again.
