B-21 Raider
This list would have been incomplete if we did not add the B-21 Raider. The Air Force was interested in a modern iteration of the Long-Range Strike Bomber, so Northrup Grumman came up with the B-21 Raider. This will be a manned aircraft, although its appeal is that it can also serve as a high-altitude stealth drone bomber. It will still need a pilot to man to control since it will deploy nuclear payloads.

BigDog Military Robot
Boston Dynamics, which came up with the BigDog Military Robot, is now owned by Google. It built this as a force multiplier. It will have the capacity to cross all terrains without falling down. This is ideal for use in desert, sand, snow, and forest. It can be used to deliver supplies to soldiers where choppers can’t.
