Russia’s fifth-generation Su-75 Checkmate single-engine fighter is set to perform its debut flight in 2025, Deputy Prime Minister Yury Borisov told reporters at the St. Petersburg International Economic Forum on Friday.

Previous reports suggested that the state-of-the-art Checkmate fighter was scheduled to perform its debut flight in 2023.

"The first flight in 2025," Borisov said, adding that it normally took 18-24 months between the debut flight and the serial production.

Head of the state tech corporation Rostec Sergey Chemezov earlier said at a meeting with Russian President Vladimir Putin that the serial production of the Checkmate light tactical fighter would begin in 2027. Currently, Russian specialists are working out the fighter’s design documentation and have engineered its first prototype, he added.

Rostec is developing the Checkmate fighter using its own funds, without federal budget financing, he emphasized.
