That article is, um, wildly optimistic. There's no question that a dual-mode airbreathing/rocket engine would be useful for launch purposes if it can be made to work, but we're not even close to making it work. Even ignoring dual-mode, achieving the targeted atmospheric performance (Mach 5.4 on jets) is improbable by 2019.
