 The core block system was also introduced in the RX-78, as well as the RX-75 Guntank and RX-77 Guncannon.This system allowed the pilot to escape the destruction of his mobile suit in a functional aerospace fighter, as well as housing a learning computer that can collect and analyze performance data from the suit's combat sorties and self-adapt for improvement.This however had to be dropped from subsequent mass-production units due to cost issues.
