Russia is currently building fourth-generation submarines and designing fifth-generation U-boats. Little is known about the new submarines, but it is clear they will eliminate problems encountered by modern nuclear submarines, online Gazeta.ru publication writes.

The Laika class submarine follows on from the Pr.885/885M Severodvinsk Class cruise missile submarines. But it is not a straightforward successor. It was first revealed in the background of a media report on a Russian defense exhibition in December. Although it has not been officially confirmed the new design is likely to be the next generation Russian attack submarine project known as Husky.
