Not as weird as the Beyonce pic ! Lmao ! <| sep |> Test post . Please ignore . <| sep |> Resubmitted as I forgot the resolution . You can find the wiki page SSGN 587 OverviewThe Halibut was a unique submarine designed to , among other things , deploy saturation divers from its saturation habitat , which was disguised as a Deepsubmergence rescue vehicle . On several occasions the Halibut was tasked with tapping Soviet communication lines , and did so very successfully . It appears the Soviets got wind of this and when the Halibut returned to collect a recording device on one occasion , it was gone . It was also involved in and collecting artefacts from the Soviet submarine 129 GolfII , which was located in around 5000 m of water after sinking in 1968 . This survey laid the groundwork for the most expensive operation in CIA history , Project Azorian , when the Hughes Glomar Explorer attempted to raise the wreck a number of years later . This has been variously reported to have been a complete failure , with hardly any of the wreck being recovered due to a failure in the claw , and a complete success , with all of the wreck being recovered but this fact hidden to cover up the amount of intelligence gleaned about Soviet technology . 4 submarines went missing in 1968 1291960 Soviet USS ScorpionSSN 589 US Video footage of wreckage of Scorpion and Thresher S 647 French Not yet been located INS Dakar Israeli Wreck p i c t u r enauticoswpcontentuploads 201410 Sailmosaic . jpgBook RecommendationsHere are some books that you might find interesting , all of which touch on K 129 to some extent .
