8. B-2 Spirit – $737 million

By far the most expensive plane on the market is the United States military’s B-2 Spirit jet, swooping in at $2.4 billion for the entire devlopment program of this aircraft! In the air since 1987, the military currently possesses 20 of these planes, after having lost one in a crash in 2008.

Also known as the “Stealth Bomber”, the B-2 Spirit has the ability to get through anti-aircraft measures, as well as deploy nuclear weapons. Clearly, this is the most powerful aircraft in the world, and the United States has 20 of them. Used for very different reasons than the commercial luxury jets above, the B-2 Spirit only fits two people. This aircraft was originally designed during the Cold War, but has been used in actual battle in Serbia, Iraq, and Afghanistan.
