Russian military designers presented the first blueprints for a sixth-generation fighter jet Wednesday that they say will be ready for service around 2025, even though the Kremlin’s PAK FA fifth-generation fighter jet is not yet in service. Moscow is being pushed into action by the United States, which has been operating the F-22 Raptor stealth fighter jet for more than 10 years and began making plans for its own sixth-generation fighter jet in 2012.
