The Gundam Double X is also equipped with two Hyper Beam Swords stored on its side skirt armor, two Head Vulcans, four Breast Launchers and can use custom-made weapons including the Buster Rifle and Defense Plate. Because of its similarities to the Gundam X, the Gundam Double X can dock with a support craft developed for the Gundam X called the GS-9900 G-Falcon. While docked with the G-Falcon, the Double X is unable to use some of its weapons, but has the ability to use the weapons equipped on the aft section of the G-Falcon. Also, while joined with the G-Falcon, the Gundam Double X is able to safely re-enter Earth's atmosphere.

Like the Gundam X, the Double X had a security key in the form of a G-Controller that is needed to activate and control it. However, while the Double X has its own G-Controller, its base system is still the same as the Gundam X. This means that even without the Double X's G-Controller, it can still be operated by anyone who has an older-model G-Controller used with the Gundam X - as demonstrated by Garrod, who stole the Double X in this manner.
