Charlie

The Charlie-class submarine refers to Soviet Project 670 Skat and Project 670M Skat-M nuclear-powered cruise-missile submarines. GlobalSecurity identifies the Charlie I and Charlie II projects and notes their unusual single-reactor, single-shaft configuration among Soviet nuclear combat submarines. Public summaries describe the class as a Soviet and later Russian SSGN, not a Chinese ballistic missile submarine. The page should correct that context in prose without changing schema: the equipment name Charlie is best treated as a Soviet/Russian cruise-missile submarine class, likely miscategorized in the database metadata.

The Charlie class was designed to attack surface targets with cruise missiles from a nuclear-powered submarine platform. Its role differed from ballistic-missile submarines: instead of strategic nuclear patrols, Charlie boats were part of the Soviet effort to threaten carrier groups and other high-value naval forces. GlobalSecurity's notes on Project 670 and 670M help explain the design lineage, while class summaries identify it as a cruise-missile submarine. A strong page should separate SSGN and SSBN roles clearly because confusing them would damage both user experience and content credibility.

Charlie-class submarines served in the Soviet Navy during the Cold War and were later inherited or retired during the Russian transition. The class matters because it shows how the Soviet Navy pursued multiple ways to hold U.S. carrier groups at risk: long-range naval aviation, surface missile ships, and submerged cruise-missile submarines. In the equipment page, this operational history should take priority over a generic submarine description. It explains why the design existed, how it fit Soviet naval doctrine, and why newer cruise-missile submarines eventually superseded it.
