F-35 was already the most expensive conventional weapons program ever gets even more costlier

The F-35 Joint Strike Fighter, the supposed backbone of the Pentagon’s future air arsenal, could need additional years of work and billions of dollars in unplanned fixes, the Air Force and the Government Accountability Office revealed on Tuesday. Congressional testimony by Air Force and Navy leaders, plus a new report by the GAO, heaped bad news on a program that was already almost a decade late, hundreds of billions of dollars over its original budget and vexed by mismanagement, safety woes and rigged test results.

At an estimated $1 trillion to develop, purchase and support through 2050, the Lockheed Martin-built F-35 was already the most expensive conventional weapons program ever even before Tuesday’s bulletins. The Air Force, Navy and Marine Corps are counting on buying as many as 2,500 F-35s to replace almost every tactical jet in their current inventories. More than a dozen foreign countries are lined up to acquire the stealthy, single-engine fighter as well.
