RQ-4 Global Hawk

Real Life
The Northrop Grumman RQ-4 is a drone designed for surveillance. It can loiter over a target area for extended periods of time to find hostile targets. Its advanced, high-resolution electro-optical/infrared sensors combined with the altitude that it flies at make the RQ-4 an excellent way to spy on the enemy. The US Air Force is the RQ-4's main user, but the US Navy uses a modified platform called the MQ-4C Triton.

Singleplayer
The RQ-4 is absent from the Campaign.

Multiplayer
The Counter UAV Scorestreak in Multiplayer uses the model of the RQ-4. Perhaps it is equipped with an advanced ECM jammer for its radar-jamming use.

Extinction
The RQ-4 is absent from Extinction.
