The NT-1 wasn't really a newtype project until they got data from Amuro sometime after the white base landed on earth. It started under the G-4 Project earlier in august before the original gundam show started. The G-4 project was just the four branches of the federation armed forces developing new MS technologies. The space force was working with Augusta Labs to make a next-gen gundam, and when they saw Amuro's data they changed the project to make a newtype MS. The air force made the transforming Gundam GT-FOUR, the army was making a heavy weapons unit, and the navy was making an underwater MS.

Also has the panoramic screen, linear seat, sliding armor, and introduced the movable frame according to the Robot Damashii profile, which was inherited by the GM Custom, GM Quel, and ultimately the Mk-II. It probably wasnt the full thing though, or like a pseudo movable frame. Either way it set the direction of all future MS. It seems to get new features every time a new toy comes out.

Nah, it was originally the 4th gundam. That's what the 4 emblem on its shoulder stood for until it was retconned into a reference to the G-4 project. The old 1/144 gunpla manual called it the 4th Gundam developed during the OYW because the Gundam Unit 4 and 5 weren't introduced until the next year and displaced the NT-1 as the 4th unit.
