The McDonnell F3H Demon is probably the least remembered modern Naval fighter, even though it was our first true all-weather missile fighter. When the weather prevented the agile F8U, F4D and F11F from flying, the Demon could still be launched. A glamorous plane the Demon was not, primarily due to its lack of performance. The F3H remained underpowered throughout its career, so much so that it was tagged by fleet pilots as the "lead sled."
