The F-35 is America’s fifth generation fighter jet, designed for service in multiple military services. It has vertical take off and landing, it can fly at Mach 1.6 (about 1200 miles per hour), and is the stealthiest jet fighter on the planet.
But more importantly, it is a flying mainframe computer. It has more battle management and data fusion capability than any fighter before it. When fighting with fourth generation fighters, it makes everyone better.
