U.S. Air Force's new F-35 jet is beaten in dogfight by F-16 designed in the 1970s

While the F-35 is a "multi-role" aircraft and not a purpose-built air superiority fighter (unlike the closely guarded F-22), the fifth-generation aircraft is designed to excel in electronic warfare, air-to-surface combat and air-to-air combat. The US is anxious to sell them to their NATO allies to replace aging F-16, F/A-18, F-4, and Harrier fleets. The F-16 has served in the Air Forces of 26 nations, including the U.S., Israel, Egypt, the Netherlands, Denmark and Norway. Most are expected to purchase the new F-35 jet. Britain plans to purchase 138 F-35 jets from the US, but at present costs that would add up to a total of $19 billion. US Vice President Joe Biden promised a delivery of the jets to Israel 'next year', amid reports that Tel Aviv has approved a new deal to add 14 more jets to its 2010 order for 19 aircraft. Australia has committed to purchasing 72 F-35s. Japan has ordered 42 F-35As. South Korea has also ordered 40 F-35As, with plans for 20 more, budget permitting.
