Technology & Combat Characteristics
Despite the exceptional performance of the transformable mobile suits introduced during the Gryps Conflict, their complexity and high cost limited their adoption by the Earth Federation and its adversaries. Anaheim Electronics, as part of its research into more economical transformable mobile suits, developed a new version of the Zeta Plus without the expensive and complicate transformation systems, but instead have the mobile suit dock with an external subflight and weapons system known as the "Back Weapon System" (BWS) to assume a waverider mode. The Back Weapon System provide the mobile suit with additional weapons storage in addition to the flight capabilities. The prototype machine, MSZ-006R Zeta Plus R, was based on the battle-proved MSZ-006C1 Ζeta Plus C1 used by Karaba, and the data obtained from it was later used to develop Londo Bell's RGZ-91 Re-GZ.
- 60mm Vulcan Gun
- Two 60mm rotary guns were stored on either side of the Ζeta Plus R's head unit. As a relatively small caliber weapon with a high rate of fire, these guns were primarily used as anti-aircraft and anti-personnel weapons, and used to ward off missiles and fast moving targets.
- Beam Saber
- The standard close-range melee combat weapons employed by the majority of Mobile Suit. The beam saber is a small cylindrical device held in the mobile suit's hands when operated and is powered by E-cap that is recharged from special racks. The beam saber emit high-energy Minovsky particles to form a blade-shaped I-field (via manipulation of electromagnetic fields), and then fills this shell with superheated Minovsky particle plasma to produce a plasma blade that is capable of cutting through almost any metal that has not been treated with anti-beam coating. The Zeta Plus R is equipped with a pair of 0.9 MW beam saber stored in a recharge rack located in the backpack.
- Hip Beam Cannon
- A pair of 14 MW beam cannons are mounted to the thigh sections of the Ζeta Plus R. They are directly powered by the Mobile Suit Generator, and can be fired automatically.
Special Equipment & Features
- Back Weapon System (BWS)
- An external subflight and weapons system that allowed the Zeta Plus R to assume a Waverider mode without the complicated and expensive transformation systems seen in the original Zeta Gundam and in the subsequent Zeta Plus series. While it was possible for the Zeta Plus R to eject the BWS during combat, the two craft could not be united again in the field. Anaheim Electronics continued to refine the BWS, where it saw limited service with the RGZ-91 Re-GZ during the Second Neo Zeon War in UC 0093.
