JD

JD was the name of the head AI which governed the organization known as The Patriots. JD had top priority, and kept command over the four other AIs which made up the organization. These four other AIs were codenamed GW, TJ, TR, AL.

JD, housed in a satellite orbiting the Earth disguised as debris, took it's name from John Doe, the real name of Big Boss, who was an idol for The Patriots.

Background
After Big Boss had left the Patriots, Major Zero lost his faith in humanity and commissioned the construction of AIs to command the organization after his death. JD, named after Big Boss himself, was to watch over and command these AIs. It is unknown when exactly they were commissioned, or when they went active, although it was late 2009 that GW was scheduled for activation, and JD itself appeared to be fully active at this time.

During The Manhattan Incident a worm cluster was uploaded into GW, splitting it into little pieces. After the incident, Liquid Ocelot managed to reconstruct GW and hide it withing JD itself, becoming a sort of data haven. When Solid Snake and Otacon uploaded the FOXALIVE virus into GW, it spread into JD and the other AIs, eliminating them forever.
