FORT WORTH, Texas --- U.S. Air Force analyses show the Lockheed Martin F-35 Lightning II is at least 400 percent more effective in air-to-air combat capability than the best fighters currently available in the international market.>> The Air Force's standard air-to-air engagement analysis model, also used by allied air forces to assess air-combat performance, pitted the 5th generation F-35 against all advanced 4th generation fighters in a variety of simulated scenarios. The results were clear: the F-35 outperformed the most highly evolved fighters in aerial combat by significant margins.>> "In all F-35 Program Office and U.S. Air Force air-to-air combat effectiveness analysis to date, the F-35 enjoys a significant Combat Loss Exchange Ratio advantage over the current and future air-to-air threats, to include Sukhois," said Maj. Gen. Charles R. Davis, F-35 program executive officer.>> Recent claims that Russian fighters defeated F-35s in a Hawaii-based simulated combat exercise are untrue, according to Maj. Gen. Davis.>> "The reports are completely false and misleading and have absolutely no basis in fact," Maj. Gen. Davis said. "The August 2008 Pacific Vision Wargame that has been referenced recently in the media did not even address air-to-air combat effectiveness. The F-35 is required to be able to effectively defeat current and projected air-to-air threats. All available information, at the highest classification, indicates that F-35 is effectively meeting these aggressive operational challenges.">> The Pacific Vision Wargame was a table-top exercise designed to assess basing and force-structure vulnerabilities, and did not include air-to-air combat exercises or any comparisons of different aircraft platforms.
