I read that however, I actually read there are actually three in operation being tested on the aircraft carrier so while not a production aircraft yet, three are actually flying.
That is the F/A-35 Lightning, sometimes known as the JSF (Joint Strike Fighter), which is supposed to replace the F-16 and F/A-18 for the Air Force, Navy, and Marine Corps. There will be three versions: land-based, carrier-based, and short take-off and landing.
I was reading in Janes Defesen review that the number is higher for the F-14.. but oh well moot point
