These ships are large, purpose built ships designed for signals intelligence gathering via an extensive array of sensors.[4] The data could be transmitted to shore via satellite link antennas housed in two large radomes. The ships are armed with two AK-630close-in weapon systems and SA-N-8surface-to-air missile (SAM) launchers, for last resort self-defense.
Operations
On September 23, 2012, SSV Viktor Leonov was at dock in Havana.[5][6] Other ships visited in 2013.[7]
On February 27, 2014, SSV Viktor Leonov docked in Havana’s cruise ship area, the same day Defense Minister Sergei Shoigu announced that Russia would establish permanent bases in Cuba, Vietnam, Nicaragua, Singapore, and the Seychelle islands.[8][9][6][10][11]
On January 20, 2015, SSV Viktor Leonov was at dock in Havana.[13]
On February 15, 2017, CNN reported that SSV Viktor Leonov,[14][5] a Russian spy ship was sitting 30 miles (48 km) off the coast of Connecticut.[15] This is the farthest north the Russian spy vessel has ever ventured, according to US defense officials. CNN later reported that Viktor Leonov, which conducted similar patrols in 2014 and 2015,[16] was off the coast of Delaware, but typically she only travels as far north as Virginia.[17][18] The ship is based with Russia's Northern Fleet but had stopped over in Cuba before conducting her patrol along the Atlantic Coast and is expected to return there following her latest mission. She was spotted operating off the coast of South Carolina and Georgia in December 2019. The United States Coast Guard at the time published a MSIB alleging unsafe operations being performed in that area, including running without navigation lights, and failing to respond to hails. The ship is outfitted with a variety of high-tech interception equipment and is designed to intercept signals intelligence. The official said that the US Navy was "keeping a close eye on it.".[19]
In the documentary series Warship: Life at Sea, filmed aboard Royal Navy type 23 frigate HMS Northumberland in Autumn 2020,[20] SSV Viktor Leonov is featured loitering off the British coast where she was suspected to be attempting to surveil a US Navy submarine en route to a British port. The Duke-class frigate took up a defensive posture between the two vessels and employed noise-making countermeasures to interfere with intelligence gathering. On the same patrol, Northumberland was involved in a further incident while tracking an unnamed Russian SSN, when the submarine collided with the frigate's towed-array sonar.[21]
