INS Dakar
INS "Dakar" () was a diesel–electric submarine in the Israeli Navy. The vessel, a modified World War II British T-class submarine, had previously been 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 . The submarine's conning tower was salvaged and is on display outside the Clandestine Immigration and Naval Museum in Haifa. The exact cause of "Dakar"s sinking remains unknown. It was one of four mysterious submarine disappearances in 1968; the others were those of the , the , and the U.S. submarine . Early career. HMS "Totem" was built as a group 3 variant of the British T-class submarine; these were constructed during World War II at HM Dockyard Devonport. She was launched on 28 September 1943 and commissioned in early 1945. After the end of World War II, "Totem , along with the other surviving group 3 boats, was equipped with submarine snorkels to allow for longer periods of operation underwater. Between 1951 and 1953, Totem" was one of eight British Navy submarines to be converted to the "Super T" design, which allowed the vessel to travel at higher and quieter underwater speeds. Purchase by Israel. In 1965, "Totem" was purchased by Israel, along with two of her T-class sister boats, and . The former "Totem" was commissioned into the Israeli Navy at Portsmouth, England on 10 November 1967 as INS "Dakar" (, ), under the command of Lieutenant-Commander Ya'acov Ra'anan . She then headed to Iceland to conduct sea and dive trials. Late in 1967, "Dakar" returned to Portsmouth; she left for Israel on 9 January 1968. "Dakar"s first port call after leaving the UK was Gibraltar, on the morning of 15 January. She departed at midnight on 16 January with the intention of crossing the Mediterranean Sea on snorkel. The original schedule was for the submarine to enter her new home base at Haifa on 2 February. During her voyage, she was making excellent speed, averaging over , and Commander Ra'anan radioed Haifa to request entering port ahead of schedule. He  was ordered to enter on 29 January. Later, Ra'anan requested to enter a day earlier, on 28 January. This request was denied, as the welcoming ceremony could not be rescheduled. Loss. At 06:10 on 24 January 1968 "Dakar" transmitted her position, 34.16°N 26.26°E, just east of Crete. Over the next 18 hours she sent three control transmissions which did not include her position. Her final broadcast was at 00:02 25 January, after which no further transmissions were received. On 26 January the British Admiralty reported the submarine was missing and gave the last known position as  west of Cyprus. An international search and rescue operation began, including units from Israel, the United States, Greece, Turkey, Britain and Lebanon. Although the Israeli Navy in Haifa began broadcasting calls to commercial vessels to be on the look out for "Dakar", Israeli officials would not admit the submarine was missing. On 27 January, a radio station in Nicosia, Cyprus received a distress call on the frequency of "Dakar"s emergency buoy, apparently from south-east of Cyprus, but no further traces of the submarine were found. On 31 January, all non-Israeli forces abandoned their search at sunset. Israeli forces  continued the search for another four days, ceasing at sundown on 4 February 1968. Israel denied that "Dakar" sank as the result of hostile action. It stated that "Dakar" was involved in crash diving exercises on its return voyage and was probably lost as a result of a mechanical failure. On 25 April 1968, Vice Admiral Avraham Botzer, commander of the Israeli Navy, stated that "Dakar" sank on 24 January 1968, two days before being reported missing, due to "technical or human malfunctioning" and not "foul play". Searches and discovery. On 9 February 1969, more than a year after "Dakar  went missing, a fisherman found her stern emergency buoy marker washed up on the coast of Khan Yunis, a town southwest of Gaza. British T-class submarines had two such buoy markers, bow and stern, secured behind wooden doors in cages under the deck and attached to the submarine with metal cables long. The experts who examined the of cable still attached to the buoy made several inaccurate determinations. These conclusions - that the buoy had remained attached to the submarine for most of the preceding year until the cable broke completely, that Dakar" rested in depth between , and that it  was off her planned route - misled searchers for decades. It was not until April 1999, after some 25 failed expeditions, that a search effort was concentrated along the original route. On 17 January 1970, the Egyptian newspaper "Al Akhbar" reported that "Dakar" had been sunk by an Egyptian warship with depth charges. The Egyptian story was told in a 2 July 2005 interview by "Asharq Al-Awsat" with General Mohamed Azab (a major at that time): The Israeli government stated there was no evidence to substantiate the Egyptian unofficial charges. During the 1980s the Israelis, using a salvage vessel with  Egyptian liaison officers, conducted three searches for "Dakar" in waters north of Sinai and another search off the Greek island of Rhodes. In August 1986, the U.S. Navy committed a P-3 Orion and an S-3 Viking to search Egyptian waters near al-Arish. In October 1998, Israel began running advertisements in newspapers in Turkey, Egypt, France, Greece and Russia, offering rewards of up to $300,000 for any information on the fate of "Dakar". On 24 May 1999 a joint U.S.–Israeli search team using information received from U.S. intelligence sources and led by Thomas Kent Dettweiler, a subcontractor from American  Nauticos Corporation, detected a large body on the seabed between Crete and Cyprus, at a depth of some . On 28 May the first video pictures were taken by the remote-operated vehicle "Remora II", making it clear that "Dakar" had been found. She rests on her keel, bow to the northwest. Her conning tower was snapped off and fallen over the side. The stern of the submarine, with the propellers and dive planes, broke off aft of the engine room and rests beside the main hull. During October 2000 a survey of the "Dakar" wreckage and the wreckage site was  undertaken by Nauticos corporation and the Israeli Navy. Some artifacts were recovered, including the submarine's bridge, the boat's gyrocompass, and many small items. The exact cause of the loss remains unknown, but it appears that no emergency measures had been taken before "Dakar" dived rapidly through her maximum depth, suffered a catastrophic hull rupture, and continued her plunge to the bottom. The emergency buoy was released by the violence of the hull collapse, and drifted for a year before washing ashore. Later developments. A memorial designed by architect David Brutzkus was dedicated in 1971 at the National Military  and Police cemetery in Mount Herzl in Jerusalem. It is inscribed with a Hebrew Bible verse from Psalm 77:19: "Your path led through the sea, your way through the mighty waters, though Your footprints were not seen." "Dakar"s bridge and forward edge of her sail are now a memorial display in the Naval Museum in Haifa. The recovery of any still-existing remains of the crew members has been considered. This would permit their Jewish burial in Israel as Judaism does not recognize burial at sea and requires burial in earth. To date, crew members' families have held a ceremony  in a ship over the submarine's remnants. The Rabbinical authorities had to solve complicated problems of Jewish law before the crew members' wives could be declared officially widows, so that they could remarry. In 2008, a film was released, entitled "Full Circle", a documentary about the search for the wreckage. In May 2009, a book was published by Nauticos president David W. Jourdan entitled, "Never Forgotten: The Search and Discovery of Israel's Lost Submarine Dakar". This book chronicles the history of the submarine, the story of the families of the 69 lost sailors, and the events leading to  the discovery in 1999. On 1 September 2015 it was reported that the previously-classified reports on the loss of "Dakar" and the subsequent search were released to the families of the submarine's crew. In 2018 the Navy proposed naming their newest submarine "Dakar" in tribute to the original vessel. After the families of the "Dakar"s crew protested, the name was changed to "Dragon", which shares the same letters in Hebrew.
