Russia is supposed to reveal a new Sukhoi stealth fighter jet at an air show near Moscow which President Vladimir Putin will attend on Tuesday. A brief video was released ahead of the MAKS air show featuring pilots from UAE, India, Vietnam and Argentina. Oleg Panteleyev, head of the Aviaport analytical agency, said it would be promoted as a US F-35 stealth fighter. It is not known when the plane might be ready for serial production. It is unlikely to take to the air when it goes on show.

Russia has spent heavily on military aircraft and new armaments under Putin’s guidance, both for its armed forces and increased export revenue from weapon sales. Many of its new weapons have still relied on Soviet-era technology from the Cold War. In May, an unnamed defence source told by state news agency RIA said Rostec was working on a fifth-generation light multi-role fighter jet with a single-engine. The aircraft was assumed to have a maximum speed of more than twice the speed of sound, to weigh no more than 18 tonnes, and to have decreased radar visibility and high maneuverability, a source said.
