Trepidity writes "United States Navy Admiral and Chief of Naval Operations Jonathan Greenert stirred a controversy by questioning much of the thinking underlying current U.S. defense technology. He argues that stealth technology is unlikely to retain its usefulness much into the future, and so focus should switch towards standoff weapons. In addition, he criticizes the focus on expensive all-in-one platforms such as the F-35 fighter, arguing for a payload-centric, flexible approach he compares to trucks rather than luxury cars."
