The Project 670 Skat submarine (Charlie class per NATO classification) was a nuclear-powered cruise missile submarine built for the Soviet Navy and later operated by the Russian Navy. All Charlie I/II class submarines are decommissioned. One Charlie was used for testing an Oniks missile. Charlie I and its successor Charlie II classes submarines are designed by Lazurit Central Design Bureau ("Lazurit" is the Russian word for lazurite).

The Charlie I class submarine (Project 670 Skat) SSGN was first launched at the Krasnoye Sormovo inland shipyard at Gorkiy in 1967 with another 10 following over a period of five years. The Charlie Is had two banks of four missile tubes angled upwards on each side of the bow outside the pressure hull. The tubes were covered by large outer doors and the design was to incorporate the P-120 Malakhit (SS-N-9 Siren) medium range anti ship missile. Due to delays in the missile development, the missile was substituted with the short range P-70 Ametist (SS-N-7 Starbright) submerged launch missile which itself was a development of the P-15 Termit (SS-N-2 Styx) surface-launched missile. The missiles were designed for pop up surprise attacks on high value surface targets such as aircraft carriers.
