In the US military budget request for the fiscal year 2022, the US Air Force proposed to eliminate up to 20 RQ-4 Global Hawk spy planes to reduce operating costs.
The move to eliminate the sizable margin of the RQ-4 Global Hawk is supposed to cut the budget. These edge-type electronic reconnaissance versions belong to the early Block 30. Currently, the United States has developed newer variants based on the RQ-4 such as the RQ-4B, and a naval version bearing the designation MQ-4C. All aircraft after decommissioning are put into special storage and can be reused when needed.
The RQ-4 Global Hawk is the most modern unmanned aerial vehicle of the US military. This type of aircraft is capable of capturing, collecting and transmitting to the base images of terrain, objects and battlefields with extremely high resolution. In addition, it can also eavesdrop on signal transmissions and record activities on the ground.
The RQ-4 Global Hawk is a product of Northrop Grumman, born in the mid-1990s. The aircraft is considered the miracle of US Air Force technology, the RQ-4 Global Hawk carries with it outstanding performance compared with the legendary Lockheed U-2.
Compared to the U-2, the RQ-4 Global Hawk spy plane does not need a direct pilot, it can hover in the sky of the enemy for days before having to return to base to refuel. . With a ceiling of over 18km, intercepting this type of aircraft is extremely difficult.
