5 of the most expensive military mega-projects of all time
Making planes, tanks, and ships isn't cheap. Now factor in the cost of personnel, housing benefits and operations and you have a defense budget that balloons into the billions.
In 2011, the U.S. government spent about $718 billion on defense. That's nearly half of all military spending on the planet. The other top 13 nations combined spent $695 billion.
While the yearly budget is spread out according to defense needs, some projects take the lion share. Case in point are weapon systems like the Virginia Class Submarine with a procurement cost of $76.6 billion and the V-22 Osprey at $95.2 billion. Although costly, they aren't the most expensive military mega-projects of all time. Here's the list:
