Sea Hunter
You will learn more about Sea Hunter once you hear that its official name is actually the Anti-Submarine Warfare Continuous Trail Unmanned Vessel. It is not hard to see why it is known as ACTUV. This was made in the hopes of making quiet submarines that can lurk close to the shores. The project is a success.

The Gladiator UGCV
Check out this modified bomb disposal equipment, which was made for the Marine Corps. Known as the Gladiator, it has better speed, range, and maneuverability than all the ones that came before this model. It is armored against small arms, so it can also serve as a combat drone. Aside from that, it has a multi-mission remote battle station that can use anti-vehicle and anti-personnel weaponry. It is good for reconnaissance too.
