The creation of the Space Combat Jet Prototype 003 enabled mankind the ability to fight in space. Before it, mankind still relied on 3rd revolution rocket fuel propulsion systems and had no transportation that was suitable for space travel.
The design of the Prototype 003 was an era-defining moment because it meant that mankind had evolved from Earth weapons to space weapons. It was not an exaggeration that ten Prototype 003s were equal to all the fire power of old Earth’s military power. With enough supply of ammunition, the ten combat jets could easily destroy Earth!
