The Igor Belousov, currently under construction, will have two ARS-600 two-seat submersibles, designed to perform an array of functions, including search, rescue and salvage of submarines in distress. The Russian Defense Ministry decided in 2011 to equip the ship with a deep-sea diving system produced by Scottish firm DIVEX, which will be delivered, installed, and tested by experts from a Russian company, Tetis Pro. At present, all Russian fleets have British-built Panther Plus and Tiger submersibles in service.
