First you must complete Mission 31 because doing so will unlock Side Op 50 ‘Capture the Legendary Jackal.’ Like with all Side Ops, there is a chance it won’t immediately appear if you have too many Side Ops sitting around undone. Clear a few if need be in order to be able to go out on this particular mission. Once completed you’ll get the notification that the requirements have been met for your to develop the Fulton +Wormhole.
Raise your R&D and Support Units to Level 40 (if you haven’t already) and save up a whopping 850K GMP, and you’re ready to develop one of the coolest gadgets in Metal Gear Solid V: TPP.
The Wormhole Fulton takes around 2 1/2 hours to develop, so just go have fun while you wait. It can’t be shot down (since there is no balloon), has guaranteed success at all times, and can even be used indoors (perfect for those tricky hostage rescues). It really is one of the most usefull item in the entire game and is well worth the effort of obtaining.
