Azorian/Jennifer was actually one of the CIA's biggest blunders and a major failure. In '68 the Navy found K-129 with a remote controlled mini sub from USS Halibut. The Navy spent a few months testing a way for Halibut's minisubs to cut into K-129 and get out the code books, comm equipment and some electronics, they didn't care about the rest as the Golf class sub was obsolescent in 1968, so was its weapons, they figured they'd have it in a few months and a low budget as they were already paying for Halibut anyways. The CIA then proposed Azorian to get the whole sub, and the Navy said that it wouldn't work, the sub would break up and they might lose the valuable stuff on the way, and it would take years and cost a fortune. Lo and behold Azorian doesn't launch until 1974, and when they try and salvage the sub, it breaks up and they only get a piece of it, which incidentally had no useful intelligence on board and all the useful stuff was scattered far and wide. And even if it had worked, it would have cost a fortune and gotten the intelligence 5-6 years after the navy would have, because the CIA forbid them from going in first to collect it to avoid sharing the glory. It was a disaster
By contrast Electric Kitty wasn't a complete failure, it was an R&D project that produced a fully functional prototype, so at worst a partial failure, as I doubt they just burned all the research and development data after its cancellation
