US Atlantic submarines and the Allied division of effort

Did the US Atlantic submarine command, SUBLANT, have notable kills or actions in the Second World War?

No notable Atlantic kills are recalled; American submarine effort concentrated on the Pacific while Britain carried much of the Atlantic burden.

No notable wartime kills by US Atlantic submarines are recalled here. USS Dorado is mentioned among American submarine losses, with a mine or friendly fire offered as possible explanations for its disappearance. The broader emphasis is the Allied division of naval effort: American forces concentrated on Japan while Britain carried much of the Atlantic, Mediterranean, and Indian Ocean burden. That allocation helped the Allies move supplies around the world despite contested waters. Submarines could deny an enemy the use of the sea, while sea control required the ability to protect and sustain one's own shipping.
