Project 677 or Lada-class submarines are the fourth generation of the Russian Navy’s diesel-electric submarines, measuring 66.8 meters in length. They can dive to a maximum depth of 300 meters and can operate for 45 days with a crew of 35. They displace 1,765 tons while surfaced and have six torpedo tubes.

The Lada-class submarines were designed at the Robin Naval Design Bureau using the latest technologies, including radar stealth technologies. Thanks to this, the submarines are almost completely silent, the company noted.
