Note to news organizations:  This is NOT the same weapon as used by the Iranians in early 2007.  The R-13 was not an anti-ship missile.  It was a Soviet submarine-launched ballistic missile (SLBM) with almost twice the range and three times the payload described in Iranian press releases.  This old liquid-fueled R-13 missile was difficult to maintain even when new and would be a very poor choice today given newer propulsion technology already employed by the Iranians, such as in their Shahab-3 design.  In any case, ballistic missiles cannot be easily converted to the anti-ship role, as their flight profiles and manuvering capabilities are completely different.

In short, by referencing this webpage, you have unfortunately given credence to an Iranian disinformation program.
