[[File:AkulaProjekt971klein.png|thumb|left|The four known versions of the ''Akula'' class]]
Of the seven original ''Akula''s, only three are known to still be in service. These boats are equipped with MGK-540 Skat-3 sonar system (NATO reporting name Shark Gill).<ref>{{cite web |url=http://www.harpoondatabases.com/Sensor.aspx?DB=5&ID=420 |title=MGK-500 Shark Gill (Bow) |website=HarpoonDatabases.com |access-date=2012-10-04 |archive-url=https://archive.today/20130419042826/http://www.harpoondatabases.com/Sensor.aspx?DB=5&ID=420 |url-status=dead |archive-date=2013-04-19}}</ref><ref>{{cite web |url=http://submarine.su/mgk500.shtml |title=Armament "MGK-500" automated sonar complex |website=Submarine.su |access-date=2012-10-04 |url-status=dead |archive-url=https://web.archive.org/web/20121018134247/http://submarine.su/mgk500.shtml |archive-date=2012-10-18}}</ref> The lead boat of the class, K-284 ''Akula'', was decommissioned in 2001, apparently to help save money in the cash-strapped Russian Navy. K-322 ''Kashalot'' and K-480 ''Bars'' [currently ''Ak Bars''] are in reserve. K-480 ''Bars'' was put into reserve in 1998,<ref name="Podvodnye Lodki 2003">{{cite book |first=Yu.

All submarines before K-391 ''Bratsk'' have reactor coolant scoops that are similar to the ones of the {{sclass2|Typhoon|submarine|4}} SSBNs, long and tubular. ''Bratsk'' and subsequent submarines have reactor coolant scoops similar to the short ones on the Oscar IIs (the ''Typhoon'', ''Akula'' and ''Oscar'' classes use the similar OK-650 reactor).
