The GNW-003 Gundam Throne Drei (aka Gundam Throne Unit Three, Throne Drei, Drei), is one of three Gundam Thrones piloted by the Trinity siblings in Mobile Suit Gundam 00. It is piloted by Nena Trinity

Among the three Throne Gundams, Drei serves more of a support role in combat to the other two Throne units. It is often the unit linked to GNW-001 Gundam Throne Eins via an energy cable to provide sufficient GN particles for the latter's GN Mega Launcher. For combat, the Throne Drei uses a GN Handgun mounted on its right forearm, GN Beam Sabers mounted on its shoulders, a GN Shield on its left shoulder, and a GN Shield Pod on its right shoulder. The GN Shield Pod is used as a weapons container for storing GN Missles, or additional GN Beam Sabers.

Its GN Stealth Field, which deploys three huge pairs of GN particle wings, is a powerful ability that releases huge amount of GN particles to jam radar and communication over a huge distance of several hundreds kilometers. To control the huge amount of GN particles dispersed over the huge distance, the Drei is installed with improved GN particle control system. The particles dispersed from the stealth field emitter can also be used to defend itself from enemy attacks. The particle consumption rate of its other equipment are lowered in order to help use the stealth field.[3]

In order to reduce weight, the Gundam Throne's body uses its torso mainframe as part of the GN Drive itself, which gives it a very different silhouette from other Gundams.[4] Also, GN Particles are distributed to each part of the body via the frame structure rather than through cords like the Ptolemaios Gundams.[4] When the coating on the surface of the frame is stripped away, luminescence can be seen due to the effects of these particles.[4] The same kind of system is used even in the frame within the cockpit.[4]

Unlike the Throne Varanus and the GN-X series, the Gundam Thrones do not need a special start-up machine in order to activate their GN Drive Tau due to the fact that they possess their own compact start up mechanism on board.[2] With the inclusion of the GNW-003/SH Liang support craft, the Throne Drei can use a GN Long Rifle.
