International Space Development Program

The International Space Development Program, abbreviated as the ISDP, is a collaborative coalition of international space programs set up by the US State Department and NASA. The program served as a means to alleviate future problems of poverty, famine and dwindling resources that will be caused by the rise of human overpopulation on the Earth projected in the late 21st century through extensive scientific research on space travel and observations of various planets in space.

The ultimate goal of the ISDP is to eventually travel and colonize planets that match Earth's parameters for sustainable life. One such planet is the planet S-1, which the Arizona laboratory research division team hoped astronauts could travel to and begin assembly of a base of operations there for future interstellar travel.

Project: Super One
Unfortunately, travel to the planet S-1 was far too difficult for ordinary humans to attempt given the dangers of long distance space travel on the health of the astronauts as well as environmental hazards. To resolve this issue, the ISDP came up with a cybernetics research project that would enhance a human so an astronaut could endure the harsh unforgiving realm of deep space. The project was codenamed "Super One" and a young man named Kazuya Oki volunteered for the conversion procedure and tests of his newly converted cybernetic body at a training facility. The original intent once tests were done was converting more astronauts into cyborgs as Kazuya was model #1 of what was to be a series of space-faring cyborgs, but a spying intruder was observing their work and escaped before security could capture him.

Destruction of the Arizona laboratory
The USA branch laboratory of the organization was destroyed in a terrorist attack by the Dogma Kingdom, with all of the researchers of that division killed, including its head scientist of cybernetics research Professor Henry.

The ISDP was seen again in a story arc featuring Kamen Rider Super-1.
