NASA Super Guppy
This plane was the first ever aircraft made by Aero Spacelines and succeeded the Pregnant Guppy. A quick glance at it would immediately tell you that it was designed for cargo. Five planes have been built in the Guppy’s two different variants, both of which have been called “Super Guppy” and all of them are currently still in service. Since it’s quite obvious how this plane got its name, we simply won’t go there.

Caspian Sea Monster
In the 1960s, the Soviet Union developed the Caspian Sea Monster, which went through continuous testing until 1980 when it got damaged after a testing accident. Back then, it was the heaviest and largest aircraft in the world and held that record for roughly two decades. During the Cold War, many U.S. missions had a sole purpose – figuring out the capabilities of the Sea Monster. It was almost undetectable to a lot of radar systems since it would always fly below the altitude where aircraft can be detected. It may be an aircraft, but it entered service with the Soviet Navy and was operated by pilots of the Soviet Air Force.
