INS Dakar

 ship wreck, submarine

INS Dakar (Hebrew: אח"י דקר‎) was a diesel–electric submarine in the Israeli Navy. The vessel, a modified World War II British T-class submarine, had previously been HMS Totem of the Royal Navy. She was purchased by Israel from the Government of the United Kingdom in 1965 as part of a three T-class submarine deal.
Dakar and her entire 69-man crew were lost en route to Israel on 25 January 1968. Despite extensive searches over the course of three decades, its wreckage was not found until 1999, when it was located between the islands of Cyprus and Crete at a depth of approximately 3,000 m (9,800 ft). The submarine's conning tower was salvaged and is on display outside Clandestine Immigration and Naval Museum in Haifa.
The exact cause of Dakar's sinking remains unknown. It was one of four submarine disappearances in 1968; the others were those of the French submarine Minerve, the Soviet submarine K-129, and the U.S. submarine USS Scorpion.
