The Northrop Grumman B-2 Spirit first flew in 1989 and 21 B-2s are still in service with the US Air Force. It is designed to be completely invisible to radar.

The unique flying wing design is devoid of any surface that would easily reflect radar waves, such as a tail.

The B-2 can carry upwards of 40,000 pounds of bombs, including nuclear weapons.

The Northrop Grumman B-2 is one of three strategic bombers currently in service in the US Air Force, along the agile Rockwell B-1 Lancer, which first flew in 1974, and the gargantuan Boeing B-52 Stratofortress, a legendary aircraft from the 1950s that has been constantly updated ever since.

The B-2 Stealth Bomber made its combat debut on March 24, 1999, bombing targets in Yugoslavia.

The B-2 is the most expensive military aircraft, at $2 billion per unit.

All B-2s are named after a US state and are among the most high maintenance planes in existence, requiring tens of hours of servicing for each hour of flight.

The plane uses a combination of technologies, such as stealth or low observable technology, that make it difficult to detect in the air.

B-2s are occasionally used for flyovers, such as this one before the 2018 College Football Playoff Semifinal at the Rose Bowl Game in Pasadena, California.

A B-2 Bomber approaches a KC-135R Stratotanker for refueling. During missions, the B-2 has to refuel approximately every six hours.

Initially, 132 B-2s were ordered, but the end of the Cold War and a reduction in defense budgets cut the order down to just 20, later revised to 21.
