There is some history behind that also, alluded to in some of the books you can find on the subject. The elephant in the room was the Soviet Union and the agreements made prior to the war's end to "share and share alike" all technology and assets attained upon war's end. The US gleaned what they could from the subs, and then used them for target practice so that they could claim "oh, we forgot about that, and sank it already - sorry - we have pictures... ??". Of course, the Soviets didn't share much of what they found either...
