“NARRATOR: Some believed the rescue subs themselves were occasionally recruited for espionage.

__: The DSRVs, as we know, took a long time to be built; they were Cadillacs, that had every incredible bell and whistle that the navy and its contractors could come up with., and they went deep. They were able to do all kinds of stuff, and probably many things we don't know

anything about.”

Guenter Klaus Walter“I was requested to head up the electrical interconnection design.”

• “I prefer not to advertise this, but the DSRV was also used for espionage purposes. . . Espionage was one of the primary reasons we needed to get this project done”
