ZAFT's first official mass-production mobile suit, the ZGMF-1017 GINN was developed by the Heinlein Design Bureau, one of PLANT's state-run military design bureaus. It boasted higher versatility and expandability than its predecessor, the YMF-01B Proto GINN, and was capable of using a wide variety of weapons. While the GINN inherited much of its design from the Proto GINN, its mobility and maneuverability were greatly improved thanks to enhanced thrusters, including a pair of large backpack thrusters. Although classified as a Zero Gravity Maneuver Fighter, the GINN could function both in space and on Earth.
In addition to the head-mounted mono-eye, which served as the mobile suit's main camera, the GINN featured a crest-shaped multi-functional sensor array with a camera at its base (with a LLLTV function), allowing the pilot to gather battlefield information in real time. This system would later be used by many ZAFT mobile suits developed between C.E. 70 and C.E. 71. Another notable feature of the GINN was that it had several hardpoints for mounting or storing its weapons, located on the left, right and back of the waist, as well as on the side of its legs.
