I'm still arguing with my graph-making sofware to get the graphic plots of this data look the way I wish. So stay tuned for the pretty plots. Until then, I hope this table will help submarine captains in Dangerous Waters avoid broadcasting their presence to their enemies. Enjoy!
|Dangerous Waters Cavitation Profiles|
|Speed||Minimum Non-Cavitation Depth|
|knots||688-I (ft)||Seawolf (ft)||AkulaI-I (m)||AkulaII (m)||Kilo (m)||Kilo-I (m)|
|13||100-140, 1601||72||30-42, 491||30-42, 49||29-40, 68||29-40, 58|
|14||111-140, 1791||83||34-42, 56||34-42, 55||32-40, 94||32-40, 74|
|15||122-140, 1981||94||37-42, 62||37-42, 61||35-40, 121||35-40, 91|
|16||1331-140, 2171||1051-1352, 153||41-42, 68||41-42, 66||39-40, 147||39-40, 1071|
|NOTE: Speeds which include a depth range (16-18kts for Seawolf and 13-16kts for the others) include an anomalous area in which the boat will cavitate. Depths inclusive of the given range are safe from cavitation (subject to footnotes, if any); Otherwise, the last depth given is the minimum non-cavitating depth. Depths between the given range and the final minimum depth will cause cavitation at the indicated speed(s); Transits must be less than or equal to 15kts for the Seawolf and 12kts for the others. For example, a 688(I) at any depth between 141 and 159 feet inclusive must be traveling at less than or equal to 12kts or cavitation will occur.|
|1 Indicated depth is safe from cavitation if you are steady at that depth before ordering the given speed. If rising at the given speed, add 1 to this depth to prevent a short period of cavitation.|
|2 Indicated depth is safe from cavitation if you are steady at that depth before ordering the given speed. If diving at the given speed, add 1 to this depth to prevent a short period of cavitation.|
|3 This combination isn't realistically possible as the standard Kilo's maximum surface speed is 9kts, and it doesn't switch to "submerged speeds" (allowing 10kt+ speeds) until it reaches a depth of 22m.|
