Joint Mine Resistant Ambush Protected Vehicle - $50 billion
Cost per unit: $1 million
Conceived during the darkest days of the Iraq war when U.S. vehicles were hit several times daily by land mines and other improvised explosive devices, the U.S. spent around $50 billion to produce 27,000 MRAPS to counter insurgent forces. At a cost of $1 million each, the lumbering vehicles quickly became beloved by the troops.
