  It's not completely true that diesel subs have to surface to recharge their
batteries, or it wouln't be true for long. Several countries, including the
US, are developing closed cycle diesels which can be run under water. In this
way the sub could recharge without exposing itself.
  
  On the other hand, the much larger and more capable nuclear attack subs
should have little trouble killing diesel subs. As quite as diesel subs might
be,they are too small to carry the sophisticated sonar carried by Los Angeles
or Sea Wolf class subs. Also the "new improved" diesel subs are still limited
by the amount of fuel they can carry.
  
  Sorry, I don't have any sources for this post. It's all stuff I picked up
from the Discovery Channel, Popular Science or the old High Technology mag.
