I was under the impression that, despite what NATO believed during the Cold War, the Alpha (and most of the Soviet Submarine force) was never intended to attempt to interdict NATO convoys across the Atlantic. The Alphas were intended as high speed interceptors to engage NATO subs rounding the North Cape seeing to attack the Soviet SSBNs
I could have sworn I read somewhere that it came out that post cold war, that while NATO was preparing for the third battle of the Atlantic, the Soviets had no intention of fighting it. Their Naval doctrine was entirely defensive - the keep the US carriers (and their nuclear armed aircraft) away from the Rodina and the NATO subs away from the Soviet SSBN bastions.
(I could be wrong, and I can't remember the source sadly)
I believe you are correct.
I read
Blind Man's Bluff a few years back (It's about the submarine cold war, good read, highly recommended) and I believe it recounted a discussion between an US Naval attaché and a Russian Admiral. They were discussing the losses of the
K-129 &
USS Scorpion. The attaché was asking about the loss of the
K-129 so far from her patrol grid (This was after the US had admitted to finding and trying to raise her) and if it was an attempted attack on America by a rogue submarine commander, and the Russian admiral replied that there were things that both sides had agreed not to discuss. The
K-129 and
USS Scorpion being two of those things, but that the attaché could remain safe in the fact that the Soviet Union had no interest in starting World War III.
Makes you wonder really. What
was the
K-129 doing in a Chinese boomer patrol grid, "close" to Pearl Harbour, and why was the
USS Scorpion lost? I doubt we'll ever know for sure given those who knew died onboard both vessels, but there is speculation that the
USS Scorpion was attacked by a Soviet submarine operating with the task force group
USS Scorpion was shadowing.
