The Gundam prototype, which has been adjusted to the RX-78-2 type specification in the completed state, is partially renovated to the RX-78-3 type specification, which has the movement performance that can be used by a new type pilot, just before the counteroffensive operation. was broken The appearance of a new type by Second Lieutenant Amuro Ray, who belongs to the 13th Independent Squadron = White Base Corps, will influence the future direction of Earth Federation Forces mobile suit development. In this development plan, the RX-78 was redesigned from the design level to a new type compatible machine, and the function was greatly changed as the model number RX-78NT-1. Developed at the North American ORGUSS base research facility, this NT-1 = Alex can be put into actual combat immediately (or rather, it will be deployed exclusively for Amuro Ray Ensign of the White Base Corps in order to be put into a large-scale counteroffensive operation. It is an aircraft that has been developed and manufactured in a hurry. In addition, since the RX-78, which was in the early stage of development, new functions have been incorporated throughout to the extent that it can be called a completely different aircraft, and in terms of design content, it has reached a level that can be called a next-generation mobile suit. The aircraft, which was launched and transferred to Side 6 in order to hasten the introduction time, was assembled and adjusted at the colony facility in a disassembled state including spare parts, and was locally delivered before the original delivery operation. It was used in actual combat, but at ORGUSS base, in order to continue collecting data with this development machine, we are making a prototype with exactly the same specifications. This was a practical test machine called the Prototype NT-1. Its completion was just before the end of the One Year War, after the NT-1 was transported to Side 6. Effectively used as an individual. This aircraft has a visible paint that conforms to the RGM-79, which is being deployed in production.
