Russian Nuclear Submarine

The Sierra class, Soviet designations Project 945 Barrakuda and Project 945A Kondor, (NATO reporting names Sierra I and Sierra II respectively), are series of nuclear-powered attack submarines intended for the Soviet Navy and currently in service with the Russian Navy.

The class is unique due to its light and strong titanium pressure hull which enables the submarines of the class to dive to greater depths, reduce the level of radiated noise and increase resistance to torpedo attacks. It is powered by a single OK-650 pressurized water reactor.

The upgraded version, the Sierra II class was specifically developed for search and destroy missions against US nuclear submarines. It has a smaller turning circle than any other modern submarine, with speeds and diving depth greater than its American counterparts. It has also improved quieting and sonar.

In addition to the model, there are also two HDRI maps as a gift that you see in the image (HdRI SKY 12k)
