A group of Russian Navy experts has departed St. Petersburg for Argentina aboard an Antonov An-128 military cargo aircraft, the Russian Defense Ministry said on Friday. They will participate in the ongoing operation to search for the submarine ‘San Juan’. The group comprises a commander and operators of the ‘Pantera Plus’ unmanned submersible, as well as deep divers and a diving doctor, TASS said. It was earlier reported that upon the instruction from President Vladimir Putin, Defense Minister Sergey Shoigu had ordered to dispatch a group of experts from the Navy’s 328th expedition search and rescue unit to Argentina along with the ‘Pantera Plus’, as well as the ‘Yantar’ oceanographic research vessel.
