MOSCOW—President Vladimir Putin inspected a prototype of a new Sukhoi fifth-generation fighter jet on Tuesday that Russia unveiled at its annual MAKS air show with an eye on export markets.
The warplane, given the project name “Checkmate,” is likely to be touted as a rival to the U.S. F-35 stealth fighter, said Oleg Panteleyev, head of the Aviaport analytical agency.
