x-2 shinshin

The Mitsubishi X-2 Shinshin (formerly known only as the ATD-X) is a Japanese experimental fifth generation military aircraft created for testing advanced stealth fighter jet technologies.

It is being developed by the Japanese Ministry of Defense Technical Research and Development Institute (TRDI) for research purposes. The main contractor of the project is Mitsubishi Heavy Industries.

Many consider this combat aircraft to be Japan's first domestically made stealth fighter. ATD-X is an acronym meaning "Advanced Technology Demonstrator – X". The aircraft is widely known in Japan as Shinshin (心神, meaning "Spirit of the Heart"), although the name itself is only an early codename within the Japan Self-Defense Forces and the name is not officially in use.

The ATD-X's first flight is scheduled for early 2016.
