Description
The Tango is a large diesel-electric attack submarine that combines the sonar suite of the later Kilo-class with the proven propulsion plant of the Foxtrot, but with much larger battery capacity for improved underwater endurance. They are also fitted with anechoic coating for improved quieting and reduced detectability by active sonars, making them well-suited for setting up ambushes.
