Technology & Combat Characteristics
A custom Mobile Suit developed in secret by Orb. Its most prominent feature was its ability to transform from a flight form to an MS form. It was equipped with a Mirage Colloid function, and was armed with functions specialized for the ODR, an organization that excelled in covert operations. Two units have been confirmed to exist.
The MVF-X01 Eclipse was also developed with the aim of giving an MS the functions of a supersonic fighter capable of operating at ultra-high speeds, high altitudes and cruising extremely long-distances. Unlike the MVF-M11C Murasame, which was also a transformable aerial combat MS developed by Orb to defend territorial waters and airspace, the Eclipse had capabilities that allowed it to attack enemy bases. Although these Mobile Suits have similar model numbers, they are machines created with different design philosophies.
Eclipse is a special mobile suit that it places burden on a bodily-inexperienced pilot, as revealed in chapter 12 of SEED Eclipse, where Tatsumi Hori spilled his blood from his mouth after facing the combined attack from the Ginn Gladiator and Aile Calamity Gundam.
History
Originally, it was planned as a strategic bomber rather than an MS, if its existence were to be revealed, it would destroy the basic principles of Orb so it is considered top secret.
The name of the machine and its development plan was "Eclipse", when the sun is in shadow—Orb's National Symbol is the sun. This is attached with nuance as it was said that "If this come to the forefront, it will drop Orb into the darkness".
With Orb under the control of the Alliance, it was concealed as the "Special Machine of the Disaster Relief Team" under the Kiou family's control and Ministry of Foreign Affairs' jurisdiction, not the military.
