The Pentagon has billed the Lockheed Martin F-35 Lightning II as the most advanced multirole fighter in its arsenal, but the most expensive piece of military equipment ever made apparently has a weak spot that could make it visible to newest air defense systems developed in Russia and China.
“The F-35’s single Pratt & Whitey F135 engine – while immensely powerful, producing about 43,000 lbs of thrust – also runs extremely hot,” defense analyst Dave Majumdar wrote for the National Interest. “The Russians – who build excellent infrared sensors – could use the F-35’s thermal signature to develop a weapons quality track to engage the stealthy new jet.”
