Uhummm I don't think Brazil will import much more drones. It is cheaper to produce them locally. This area was kinda of neglected by the armed forces, but recently some companies in Brazil has taken in interest in drones. Drones are more simple to make and Brazil have a big aero industry that will probably start making their own military drones soon. With them is much easier to patrol gigantic areas, like the Amazon, with a lower cost.
Here is one of the projects of a VTOL drone that was recently released in Brasil. One of the companies making this one is Turbomachine, the same that helped with the TKF-500 engine some comments above. And big companies like Embraer might one day enter this makert too. There are others, but his one has unusual looks, so I decided to post him hehe.
We had some good news about the Brazilian military industry this year. The Gripen, KC-390, the launch of a hypersonic platform, submarines, missiles. It is nice to see some good news after a long economic recession.
