This is a little curious and slightly disturbing

While surfing through some photos of the aircraft carrier Admiral Kuznetsov at the pier, I ran across these photographs:

What is that in the upper right corner, behind the kingpost on that red ship moored nearby?

Why it appears to be the former Golf class diesel powered ballistic missile submarine K-118, later converted to a communications submarine and now in its final resting place, next to the Kuznetsov.

You'd figure that a country which has an ambition to build six aircraft carriers in the next forty years would find the time and money to dispose of their junked ships properly, instead of just leaving them derelict at the carrier pier.
