Due to the large-scale military conflict between the Principality of Zeon and the Earth Federation Forces that ended in January UC0080, which was later called the One Year War, humankind lost various resources, including its population, at the same time as many other wars that had been fought in the past. technology innovation. And it was the humanoid tactical mobile weapon = mobile suit that decided the victory or defeat in this war. The mobile suit gave the Zeon forces a huge advantage in their surprise attack against the Federal Forces, which outnumbered them in quantity. On the other hand, the Earth Federation Forces were behind in its development, but the RX-78, commonly known as Gundam, which was designed and developed with thorough research and assumptions of anti-mobile suit warfare, is the most excellent aircraft among the two armies. It was completed and left various achievements. It is undoubtedly the best aircraft in the One Year War. In UC0081, one year after the end of the war, the Earth Federation government obtained parliamentary approval and began restructuring the greatly exhausted Earth Federation Forces. We will also proceed with the development of the next-generation mobile suit, which has proven its effectiveness in field-of-view combat. The Earth Federation Forces appointed Lieutenant General John Cowen as the chief development officer, and in order to develop new mobile suits and the most powerful tactical weapons, they secretly launched a new general-purpose tactical weapon development project called the GUNDAM DEVELOPMENT PROJECT. did. However, the main body of development, the Federation weapons industry on Earth, which should be a limb, is also in the midst of reorganization of the manufacturing base, and the headquarters of the Federation military is based in the lunar city of Von Braun, Anaheim, which continues to expand its business significantly after the war.・I instructed the electronics company to submit several design proposals to meet the required performance. They sought the means of development from a giant conglomerate that escaped the ravages of war as a military industry. After all, it can be said that such a dominant stance of the Federation represented a constitution that did not change even after the end of the war. However, the fact that it was a mobile suit development was kept secret in the budget, and it was recorded under a different name, so there was no mention of it in the defense white paper of the same year. Regarding this matter, there is a tendency to speculate that former Earth Federation Forces General Jamitov Hyman, who had influence on the finance department of the Earth Federation government at the time, was working on a plot, and Titans was established as a reserve fund that was considered unspent. It is believed that it was diverted to the budget of the time. The main subject of the plan was a thorough redesign of the completed Gundam RX-78. Within the Earth Federation Forces, which was on the side of the victorious nation, the symbolization of these aircraft was considered a relatively important factor. That's what Gundam is for. As a development outline, Anaheim submitted Plan A, which mainly focused on operational operations under gravity, Plan B for a strategic nuclear heavy attack aircraft, Plan C, a large mobile weapon specialized for space combat, and purely space warfare. It is a convenience 4 plan of the D plan for melee battles specialized for combat. In particular, plan A is a machine that adheres to Gundam in its appearance, and as its first development mother machine, this prototype was given the development number of RX-78GP01, and the name of Gundam Zephyranthes as a pet name unique to this series. Given the. One of the features of the Gundam incorporated into the GP01 is the operational review of the Core Fighter in the convertible aircraft configuration. The previous RX-78 consisted of a special mechanism in which the recovery type main control center core fighter = core block was combined with the upper body A part and lower body B part of the fuselage, but the core block also used as a pilot recovery system. The Fighter itself did not have the definite movement performance or offensive capabilities of a fighter, and the functionality of the Gundam was only demonstrated in the form of a mobile suit. However, due to the introduction of mobile suit development technology from the Principality of Zeon and the use of a highly refined Luna Titanium (Gandarium Alpha) alloy, it is possible to generate strong torque and reduce the burden on the body. Since this has become possible, this GP01 greatly strengthens the core fighter's single-machine attack capability and main engine, making a major change in direction to a design that takes the lead in the central part of the mobile suit form. let me The thrust of the core fighter itself becomes the thrust of the mobile suit. In particular, along with the aforementioned remarkable improvement in aircraft strength, both arms and lower limbs have independent and distributed drive systems on each side, so it is possible to maintain a completely different range of motion and strength than the former RX-78. It has become possible. In this new Gundam-type mobile suit RX-78GP01, which was made immediately after the war, an excessively directed anthropomorphism is intentionally shown on its head. The original main camera is still focused on the head, but in addition to the main camera on the top of the head, a camera eye equivalent to the human eye called a dual camera system monitors the appropriate parallax in the combat distance range. It also plays a role in correction, and is a major feature in forming the "face". This is also a design concept not seen in the Principality of Zeon. In addition, the Vulcan cannon, whose usefulness outside of close quarters combat was questioned, is again laid out on this aircraft. This can be thought of as equipment for the purpose of controlling urban areas, suggesting the purpose of the Earth Federation Forces' mobile suit operation. All of the design proposals that the Federation Forces assumed that they would be able to demonstrate their abilities most effectively in their respective combat situations were decided to be manufactured simultaneously, and it is this plan that each of the prototype test aircraft has been devoted to the production of a single machine. It also shows the peculiarity of This first prototype, GP01, was loaded on the Pegasus-class amphibious assault ship Albion together with GP02 and transported to Torrington base for ground testing. Second Lieutenant Kou Uraki, who was to pilot the plane in an emergency, volunteered for Albion's pursuit unit, and after that he was to participate in actual combat, but he was a former Zeon Mobile Assault Force Marine Corps lieutenant colonel, still in the GP01, which was designed for operations under gravity. The aircraft was wrecked during the battle with the space fleet led by Cima Garahau, and was eventually refurbished into a space battle specification aircraft at the Anaheim headquarters in Von Braun.
