MSZ-006C1［Bst］ Zeta Plus C1 "Hummingbird"

The MSZ-006C1 (Bst) Z plus "Humming Bird" is a upgraded transformable mobile suit derived from the MSZ-006C1 Ζ Plus C1, Featured in Gundam Sentinel.

Technology and Combat Capabilities
The Z Plus, although designed at first only for a semi-official series Gundam Sentinel, got its designs to retcon the supposedly earlier model, the MSZ-006 Zeta Gundam. After the Gryps Conflict ended the Earth Federation wanted the design of the Ζ Gundam to be reworked, so that it was more streamlined, less complex, and, most importantly, cheaper to manufacture, but so that it would still retain all of the major strengths of the original unit. The Ζ Plus line of mobile suits was the answer to the Federation's requests.

A high-speed attack version of the MSZ-006C1 Zeta Plus C1 designed to escort the MSA-0011(Bst) S Gundam Booster Unit Type. The original plan was to replace the arms and legs of the Zeta Plus with the same booster units used by the MSA-0011(Ext) Ex-S Gundam, restricting this machine to waverider form. In order to increase its support capabilities, the plan was revised so that this version could transform into mobile suit form as well.

The redesigned limbs of this C1[Bst] type are stored inside the booster units when it changes into waverider form. Because this reduces its propellant storage space, external propellant tanks can be installed between its legs. The acceleration performance of this machine theoretically exceeds that of the booster-equipped S Gundam, and it is anticipated that it can be used as an interceptor as well as for long-range penetration missions.
