8th sister of the Alfa-Class attack submarine line, produced in the early 90s, far later than her sisters, as an ultimately failed experiment into renewed production.
Featuring improved passive sonar and noise dampening, combined with the ability to launch more modern torpedoes capable of wire-guidance but at the cost of 2 torpedo tubes, Mid-Frequency active Sonar and a severe reduction in overall length and internal space from her older siblings. While the improvements proved an impressive trade-off, the outright cost of production and far higher upkeep costs not only prevented any further production of 'new breed' of Alfa class submarines but also resulted in a relatively short active service life of roughly 20years.
Struck from the Russian naval register in the late 2000s and released following retirement, she has since been linked to the disappearance of several whaling ships since 2010, with the latest of these, at the time of this writing, being as late as January 2019. The method of their disappearance has not yet been proven, but the lack of evidence and prior performance during combat tests suggests ingestion. Crews aboard these ships have not been harmed during regular interceptions, with the exception of the trawler [REDACTED] which appears to have opened fire without provocation. No further action is required on this matter at this time.
So long as one is not hostile, or trying to actively harm marine life nearby, K-577 remains a relatively easy going and well mannered representative of her class. Can be relied upon to render assistance if she can be contacted. Caution should be used when approaching due to her size.
Sonar frequencies and signature data attached [REDACTED] Non-Combatant, do not engage.
