AeroVironment airline (USA) has successfully tested the unmanned reconnaissance aircraft - Global Observer at a desert in Southern California last weekend. During this test, Global Observer flew continuously in the air for 4 hours.

However, design engineers said the Global Observer unmanned aircraft could be aerial for at least a week . Current unmanned reconnaissance aircraft can only operate continuously in the air for a maximum of 30 hours .

It is known that the Global Observer is designed with a long wingspan of a Boeing 747 . Fuel is used for aircraft due to this hydrogen. The advantage of this new generation of unmanned reconnaissance aircraft is that it can operate continuously for a long time in the air, increasing the efficiency of collecting information and minimizing costs .

Two other major US airline companies, Northrop Grumman and Boeing, will also test their latest generation of unmanned aircraft for the next few weeks.

Northrop Grumman will test the X-47B batwing drone. The aircraft can take off from an aircraft carrier and can carry laser-controlled bombs. Meanwhile, Boeing will also test the highly anticipated Phantom Ray aircraft. Phantom Ray can approach enemy targets without being detected by radar.
