Clocking in at just $134 million per plane, the F-35B fighter jet is the most expensive sibling in its long-troubled family. The F-35s have been plagued for years with frustrations, cost overruns, and developmental difficulties. Designed to share parts with its Air Force and Navy brethren (the F-35A and F-35C, respectively), the F-35B also has the difficult task of replacing the U.S. Marine Corps' venerable Harrier Jump Jets. In order to fill those jumping shoes, it has to successfully take off in a short distance and land vertically. At operation trials over the past week on the USS Wasp, the F-35B demonstrated just that: for more than one hundred million dollars a plane, it can at least do what it promised.
