And that is why I turn my brain off when reading any Clancy novel.
Hell, I checked because I figured my memory would be faulty, and it turns out Ramius' wife was a niece of the COMMANDER OF THE SOVIET NORTHERN FLEET. The way the Soviet system worked, it was all about connections ; It's kind of like that in the west, too, but there's a major difference in that it was both widely accepted and common in the USSR to get promoted because you supported this or that man, and your status as a party member/non member, your political affiliation to certain politicians etc. were all very important. So, an admiral of the entire northern fleet would be able to pull a lot of strings, and Ramius himself would have more connections still.
Plus, think of the damn circumstances: an incompetent doctor treating families of SSBN sailors would be making enemies in mid to high positions left and right. Even a Politburo member would've been unable to protect him for long. The guy would either get "demoted upwards" into a position where he'd be unable to do anything wrong again, or fall along with his father.
Ramius being frustrated with such bullshit isn't out of the question, actually, but his portrayal as a helpless man abused by the Soviet system is absurdly unlike anything which could possibly happen in the USSR - especially since a non-Russian deemed politically reliable to command a new experimental SSBN (And hand-pick his officers, too!) would be...well, either extremely competent or VERY well connected indeed.
It just shows how Clancy kind of fills in the blanks with American practices, where commanders have nearly all the say in how they run their boats, rather than figuring out the way it's actually done in the USSR. While simultaneously criticizing the rigidness of communism
