The Project 670M Skat-M (NATO: Charlie II-class) SSGN was an improved variant of the Charlie I-class Soviet nuclear-powered cruise missile submarine. Entering service in the 1970s, it featured upgraded weapons and systems for enhanced anti-ship strike capability against NATO surface fleets, particularly U.S. carrier battle groups.
The Charlie II was armed with eight P-120 Malakhit (SS-N-9 Siren) cruise missiles, which had greater range and improved targeting over the P-70 Ametist missiles of its predecessor. These missiles were housed in vertical launch tubes forward of the sail, allowing for underwater launch. It also carried 533mm torpedoes for close-range engagements.
With a submerged speed of 24 knots and a maximum depth of around 350 meters, the Charlie II remained an effective platform but was still considered noisier than its Western counterparts. It served as a transitional design before the introduction of the larger and more capable Oscar-class SSGNs in the 1980s. The class was retired by the 1990s, with some units transferred to the Indian Navy under lease agreements.

![The Navys $19 Billion Gamble on Guided Missile Battleships
In this Naval News episode of Sub Brief, we break down the renewed discussion around a battleship-scale surface combatant—what some are calling BBG(X)—and why the idea keeps resurfacing inside Pentagon, congressional, and naval strategy circles.
This video explains:
What the proposed “new battleship” actually is (and what it is not)
Why missile saturation, survivability, and fleet air defense are driving the debate
How this concept compares to destroyers, cruisers, and submarines
The cost, industrial base, and strategic risks involved
Why AUKUS commitments and China’s rapidly expanding navy are forcing hard questions about the future surface fleet
This is not nostalgia—and it’s not science fiction.
It’s a serious discussion about naval warfare in a missile-dense, peer-conflict environment.

This video explores the Distributed Lethality Concept and the Navy Guided Missile Battleship (BBG[X]) Program, focusing on its background and issues for Congress. We examine how this concept influences **future warfare** and the role of the **us navy** in maintaining **sea control**. The visuals also display Chinese naval construction in Shanghai, including various types of **warships** and a missile test tracking ship, highlighting ongoing developments in **naval warfare**.
