Dr Alexander Shiplyuk headed up a prominent Russian facility focusing on hypersonic flight. A member of the Russian Academy of Sciences, he was involved with “high-speed aerogas dynamics” and the aerothermal dynamics of hypersonic aircraft, according to the Russia state news agency.
Vladimir Putin has consistently reiterated the importance of hypersonic missiles for the Russian military arsenal, announcing the Russian navy will be equipped with Zircon hypersonic missiles capable of reaching 6,600 mph.
Dr Shiplyuk, of the Institute of Theoretical and Applied Mechanics of the Russian Academy of Sciences’ Siberian Branch, was sent to the capital’s Lefortovo detention centre, according to the Russian state news agency TASS.
Vasily Fomin, the institute’s scientific director, was quoted by TASS as saying “investigative activities were held in the institute”.
He added: “They are linked with our director, Alexander Shiplyuk, who has been arrested.”
Russian state media then reported that an unnamed source within the investigation said Dr Shiplyuk was suspected of passing on classified information linked to Russia’s hypersonic research.
They added the case was being handled by the FSB, Russia’s security service.
The source then said Dr Skiplyuk was facing the “same charges” as Anatoly Maslov, who was detained last month.
Professor Maslov is an expert in aerohydrodynamics at the Novosibirsk State Technical University.
