Operation Atrina was a 1987 Soviet Navy submarine operation, during which five Victor-III class boats - K-244, K-255, K-298, K-299 and K-524[1] - were deployed from Zapadnaya Litsa base to the Atlantic shore of North America.

The March to May 1987 operation involved taking a longer path around Greenland instead of the usual route via GIUK gap to avoid SOSUS.[2] Developments in Soviet submarine technology - related, among other things, to spy activity[3] - further complicated the detection.[4]

Atrina remains a highly debated topic in Cold War history - while Soviet and Russian authors raise it to an almost mythical status,[1][5][6][7] Western sources claim complex yet successful tracking of at least four boats.[2][8][9]

Multiple media in both Russia and West made connections between Atrina and 2019 Operation Grom, saying the latter was a Russian attempt to break into Atlantics under disguise of Russian Northern Fleet naval training[2]
