If you are interested in being up to speed on the Russian Navy, the US Naval Institute has provided access to an Office of Naval Intelligence (ONI) briefing book on the Russian Navy.
“Cdr Salamander” provides an intro to the publication on the US Naval Institute Blog.
Unfortunately I did not see anything about the Russian Coast Guard in my initial scan of the document. It is a not insignificant force.
On page 5, where you see the 1000 mile rings that the document suggest the Russians have a special interest in, you might notice that one includes most of Alaska.
It is a nice, readable update.
