MSZ-006B Zeta Plus B was a trainer type variant of the Zeta Plus units. The mobile suit was featured in the photo-novel Gundam Sentinel.
Technology & Combat Characteristics
This particular unit was modified for use in space. Like all of the other Ζ Plus designs the Ζ Plus B could transform into a waverider mode. The Ζ Plus B was much more streamlined than previous Ζ Plus units. The barrels of the hip beam cannons were shortened to make them more aerodynamic, and the shield that functioned as the nosecone in waverider mode was rounded significantly.
The Zeta Plus is the first transformable mobile suit used by the Karaba resistance group, and its pilots have no previous experience with these complex machines. As simulator training alone is inadequate for complicated high-G maneuvers such as midair transformation, Karaba converts a handful of MSZ-006A1 Zeta Plus A1 units into two-seater trainer machines to help pilots adapt to the new mobile suit. In addition to its expanded cockpit, this B type also has a new head for its mobile suit form.
The B type is used by the regular Federation Forces as well as Karaba. The Gundam pilots of Task Force Alpha are trained on these machines at Nellis Air Base in Nevada while they await the delivery of their new mobile suits.
