 And speaking of military, modernizing the U.S. military's key missile stockpile is blowing up the budget. The Pentagon's plan to replace the Air Force's intercontinental ballistic missile fleet is now projected to cost 81% more than expected and will be delayed for a few years, according to top Pentagon officials. The new Sentinel ICBM will replace the 50-year-old Minuteman III's in America's nuclear arsenal, but it will now come with a price tag of close to $141 billion.
