Lines: 19 Approved: military@amd.com From: Mikael Borgman A lot of the responses concerning submarines has stated that diesel-eletric- subs has to surface or snorkel to recharge batteries and thus has a very limited range when submerged. This is not true. There exists at least one class of oxygen independent diesel-electric submarines, the latest swedish navy subs. They can thus stay submerged for at least a couple of weeks at a time, and can keep up full submerged speed as long as the diesel lasts, continually generating electricity with their closed-system main engines. I'll try to dig out more info concerning this and post it later. (I'm actually not shure about the engine being a diesel one, it could be running on something else, but the principles are the same.)
