The Boeing B-52 Stratofortress has been used by the US military since the 1950s. It is nicknamed "the Buff", which is short for "Big Ugly Fat".
Aerial footage showed a charred, smoking landscape where the crash occurred.
The B-52 is a long-range strategic bomber that has been participating in bombing raids on Iran during the latest US-Israeli war on the country.
Capable of flying at up to 50,000 feet (commercial airliners fly around 35,000 feet) the colossal bomber's 70,000lb payload can include hundreds of conventional bombs and 32 nuclear cruise missiles.
It can refuel in mid-air - giving it a potentially unlimited strike range. This created a "nuclear umbrella" for the United States during the Cold War, back in the era of Mutually Assured Destruction.
They typically carry a crew of five - an aircraft commander, pilot, radar navigator, navigator and electronic warfare officer.
