Why the Type 2000 SK was unlikely to enter U.S. Navy service

Did the German Type 2000 SK submarine have a realistic chance of U.S. Navy adoption?

It could be considered, but adoption was unlikely because the U.S. Navy was committed to nuclear submarines and would face domestic construction questions.

The Type 2000 SK proposal had some chance of consideration. By the late 1970s, however, the U.S. Navy was firmly committed to nuclear submarines. A conventional German design therefore faced a strategic preference more important than its individual performance. Any serious purchase would also raise the practical question of where the boats would be built in the United States.
