Russia’s new Project 21300 submarine rescue ship Igor Belousov is currently conducting underway trials with the Bester-1 (AS-40) deep submergence rescue vehicle (DSRV) embarked.
The ship completed the first phase of trials in early January, according to Russian news agency reports. Further trials will culminate in deepwater testing with the Northern Fleet later this year.
Igor Belousov was laid down in late 2005 at Admiralty Shipyards in St. Petersburg, and was launched in October 2012. Delivery was scheduled for 2014 according to Tass news agency, but the Russian Navy will now receive the ship by the end of 2015.
