MGSV:TPP how to unlock wormhole

After you finish Chapter 1 (after Mission 31), you’ll get the side op 50 – Capture the Legendary Jackal. This mission will take you to Africa, to an area south of Nova Braga Airport. Take D-Dog with you, as he can smell wild animals. You’ll find a pack of jackals, so don’t go rushing in. The one you’re looking for has black fur on his head. Once you knock him out and extract him, the option to research the wormhole fulton will appear in your Development screen.
