X Rudder Submarines questions

I don't understand why you insist this is Collins Class?
Why other country couldn't use X-rudder

Hi jandanagger,

Orangetom hasnt posted on ats for a long time now.

However in regards to the x shaped rudders on the back of subs in a seperate thread and conversation he went on to explain further.

If you notice some subs have normal + shaped rudder but just forward of them youll see a pair of smaller rudders on 45 degree angles like the × shaped rudders.

This is done for further stability of the submarine when underwater. The × shaped rudders reduce a phenomenon called 'porpoise-ing' a up down undulation of the sub as it travels. So for those wishing to cut down on that they experiment with × rudders or some combination of.
