Editing RPK-2 Vyuga (section)

==Design==
The RPK-2 uses a 82R [[torpedo]] or 90R nuclear depth charge in the 533&nbsp;mm version, and a 83R torpedo carrying{{Clarify|date=September 2010}} or 86R nuclear depth charge in 650&nbsp;mm version.

Both submarine- and surface-launched versions exist. The surface-launched versions are used by the {{sclass|Slava|cruiser|5}}, {{sclass|Kirov|battlecruiser|5}}, {{sclass|Neustrashimy|frigate|5}} and {{sclass|Udaloy|destroyer|5}} classes. The submarine-launched versions are used by the {{sclass|Akula|submarine|5}}, {{sclass2|Oscar|submarine|5}}, {{sclass2|Typhoon|submarine|5}}, {{sclass2|Delta|submarine|5}}, {{sclass2|Kilo|submarine|5}}, and {{sclass2|Borei|submarine|5}} classes. However, the munition package used in either is identical and hence the ship-launched version is launched into the water and submerges before firing its engines.
