TOP HYPERSONIC RESEARCH SCIENTIST HELD AFTER ARREST

A Russian court on Thursday ordered a 73-year-old leading specialist in hypersonic technology to be held in custody for two months on suspicion of state treason, the latest in a series of such cases. Security officers arrested the suspect, Alexander Kuranov, general director of the St. Petersburg-based Hypersonic Systems Research Facility, in Moscow, state news agency TASS cited a law enforcement source as saying. Kuranov oversaw work on the concept for a new hypersonic aircraft dubbed Ayaks that dates back to the Soviet era, according to his facility's website. Hypersonic technology allows objects to travel much faster than the speed of sound. Russia, whose ties with the West have deteriorated to post-Cold War lows since 2014, has been developing a number of hypersonic weapons in recent years that President Vladimir Putin has touted as unparalleled and lavished praise on. The detainee is suspected of passing secret information to a foreign citizen about hypersonic technology research, Interfax news agency cited an unnamed source as saying.
