TJ

TJ, named after Thomas Jefferson, was one of the proxy-AI systems used to govern and run The Patriots. It is located somewhere in Southwest Africa.

Peace Walker Incident
Main Article

In 1974, an early concept of the TJ AI controlled the second unmanned prototype that Big Boss (Naked Snake) fought and destroyed during the Peace Walker Incident.

Early Construction
Around 2000, Zero (with Sigint's help) commissioned the construction of the TJ AI.

In 2014, the TJ AI was unable to realize that the damaged GW AI was pieced together for Liquid Ocelot's insurrection, and installed it aboard a stolen Arsenal Gear battleship. The restored GW and it was inadvertently used as a conduit by a computer program that was uploaded (via Old Snake and Otacon) into TJ and the other AIs (TR, AL, and JD), thus shutting down the Patriots' system entirely.
