6) IAI Eitan

The IAI Eitan also known as Heron TP is an unmanned reconnaissance aircraft developed in Israel. The aircraft is a newer version of the IAI Heron. A medium-altitude, long endurance (MALE) UAV, the Eitan can operate at altitudes above commercial air traffic and features all-weather capability. It is a high-wing cantilever monoplane with wings of high aspect ratio. Booms extend rearward from the wings and carry twin tails that are joined by a common horizontal stabilizer.

7) BAE Systems Taranis

The BAE Systems Taranis is a British unmanned combat aerial vehicle (UCAV) technology. The aircraft, which is named after the Celtic god of thunder Taranis is designed to fly intercontinental missions and will carry a variety of weapons, enabling it to attack both aerial and ground targets. It will use stealth technology, giving it a low radar profile, and it will be controllable via satellite link from anywhere on Earth.

8) Northrop Grumman RQ-4 Global Hawk

The Northrop Grumman RQ-4 Global Hawk is also known as Tier II+ during development. The Global Hawk performs a similar role as the Lockheed U-2. The RQ-4 provides a broad overview and systematic surveillance using high-resolution synthetic aperture radar (SAR) and long-range electro-optical/infrared (EO/IR) sensors with long loiter times over target areas. It can survey as much as 40,000 square miles (100,000 km2) of terrain a day

9) General Atomics MQ-1C Gray Eagle

The General Atomics MQ-1C Gray Eagle is a medium-altitude, long-endurance (MALE) unmanned aircraft system (UAS). It was developed by General Atomics Aeronautical Systems (GA-ASI) for the United States Army as an upgrade of the General Atomics MQ-1 Predator.

10) Dassault nEUROn

The Dassault nEUROn is an experimental unmanned combat aerial vehicle (UCAV) being developed with international cooperation, led by the French company Dassault Aviation. Countries involved in this project include France, Greece, Italy, Spain, Sweden, and Switzerland. The design goal is to create a stealthy, autonomous UAV that can function in medium- to high-threat combat zones.
