Zeon's mobile weapons in the latter half of the war are prominently specialized according to the tactical content regardless of whether they are on the ground or in space. It is no longer necessary to focus on the versatility of mobile suits as the front expands, and instead the focus is on the scale of fleet warfare, which accompanies the mobile suit unit and is the main axis of operational action. It was the development of a heavy mobile weapon mobile armor equipped with a large firearm. The development approval symbol was differentiated by using the abbreviation of MA for the MS of the mobile suit. And, in parallel with the development of these mobile armors, it was a prototype development plan equipped with the brain wave guided weapon Psycommu.
The Zeon General Army Headquarters, which aimed to discover and train pilots with special sensitivity called "new type", aimed to introduce tactics comparable to the electronic weapon battle in the old state, and the plan to be installed in the mobile suit is MS. It was drafted as -16X, and was given the common name of Zeong in advance to be the culmination of mobile suits. Actually, three types of operation modes are prepared as planned mother machines for weapons equipped with Psycommu. One is a medium-sized fighter (the aircraft was later diverted to MA-06 Val Valo), and then a large fighter that will eventually bear fruit from MAN-03 Braw Bro to MAN-08 Hermes, and finally the MS-16X mobile suit. This machine with the development approval number of MS-06Z was manufactured based on the MS-06F type as a type development mother machine. In the design plan of the MS-16X plan, it will be a large machine of 40m class, which is more than twice as large as the normal mobile suit, so this Z type was developed as a downscale machine of the plan plan. The Psycommu system is under the control of the general army and is lent to each army according to the development plan. This project is given the code name of the Bishop project, and under the control of the home air defense unit under the direct control of the commander, the Z-type experimental unit of the guided weapons development department belonging to the unit is equipped with supply equipment from Granada to the Zanzibar-class experimental mother ship Remria (as an escort ship). An additional Musai-class cruiser was accompanied) and was transferred to the Corregidor reef space for testing. Units 1 and 3 equipped with a wire-guided beam cannon manufactured for the MS-16X and Unit 2 with a prototype arm of 06 type were prepared (however, this aircraft is due to the miniaturization of the beam cannon). Due to frequent damage accidents due to problems with the output system, it was later refurbished to the same specifications as Units 1 and 3). Although it is a small aircraft equipped with the Psycommu system, the total thrust reached 388t, and operational experiments under high-speed maneuvering were repeated. However, due to the large amount of fuel consumed, the operation time was as short as about 10 minutes (it is also reported that the required values were not met due to the lack of ability of the selected pilots, and sufficient maneuvering operations could not be performed). It seems that the area did not come out. For operational tests in Corregidor, which is a battle space, each aircraft was given a dark green camouflage for actual battle, and each part of the aircraft was marked with the machine number.
