I cant find any mention here of a Chinese Kilo Class sub surfacing close to the carrier USS Ronald Regan last month.
AIP doesn't have the power to run the motors at full speed.
I do not think any AIP sub is capable of running at 30 knots at all.For a sub to have been able to keep up with a carrier strike group, it has to be nuclear, or at least something with AIP like a Yuan. But even an AIP Yuan will probably not be able to run several hours on AIP at 30+knots.
Generally the AIP unit is not for high speed use...rather, for regular use simply to extend submerged time significantly.
I will look for documentation...but I believe that is correct.Jeff,
I understand AIP's provide the capability to operate at slow speed for extended periods. I don't believe high speed and AIP are even compatible. Can you confirm that. For example, I read that the Soryu's optimal speed is 6 knots using AIP for three days (source : Submarine matters).
Exact, the more fast SSK are Argentinians Type Tr 1700 a big customized Type 209.I do not think any AIP sub is capable of running at 30 knots at all.

The submerged speed for almost all Diesel/Electrics, including AIPs is 20 knots max. Most surfaced speeds are 10-12 knots.
