what caused the isreali submarine dakar to sink
For 31 years Israel never ceased her attempt to find her lost sons. 1 of Israel's strongest traditions is to bring dwelling house all killed and missing soldiers. In Israel'south 52 years of existence she paid dearly for getting the remains of her MIA warriors. Jews will do their outmost in social club to give a proper Jewish burying to every Jewish deceased.
For 31 years the search went on, year after year. 25 search missions were launched, every expedition searched a unlike role of the Mediterranean. Forth the years more advanced methods and techniques were used together with the evolution of the marine and deep-ocean science and technology.
For 31 years all effort were in vain. 25 missions that searched nearly every function of the eastern Mediterranean were fruitless. As weird as it sounds, the only area that was non checked was along Dakar's route to Haifa. Along a virtual form betwixt her last known position point and Haifa. Why did it accept 31 years to discover Dakar where she logically should accept been. The answer has 2 parts. One is the emergency beacon marker that was washed to the coast of Khan Yunis a year after Dakar's disappearance and the other part of the reply is the advanced techniques for deep ocean exploration that were developed forth the terminal 3 decades and became handy just lately.
Dakar's Stern Emergency Buoy Marker

| S.O.S H.Thousand. SUBMARINE DAKAR SOS |
On Feb 9th 1969, a year later Dakar'southward disappearance , an Arab fisherman found Dakar's stern emergency buoy marker on the declension of Khan Yunis, an Arab village south/west of Gaza. The Dakar had 2 such buoy markers. One in the bow and one in the stern. They were secured behind wooden doors in cages under the deck and attached to the submarine with metallic cables 200 meters (600ft) long. Those doors could exist opened from the inside of the submarine. When a submarine is unable to surface, the coiffure can open up the doors and the buoy will surface and transmit for the next 48 hours an SOS message. The location of the sunken submarine can then exist determined by radio direction finders. Part of the cable (65 cm) that attached the buoy to the Dakar was found. Scientists and experts examined the buoy number of times and adamant that the beacon was attached to the Dakar for a twelvemonth until the cablevision broke completely. Information technology was determined that the Dakar rests in depth between 150 to 326 meters, and that she is 50-70 nautical miles abroad from her planned route.

Today, later on the rediscovery of Dakar it is clear that the conclusions of sea experts and marine scientists were false and misled the search operations for 31 years. Dakar never diverted from her planned road and her wreck rests in a depth of almost 3 kilometers. The emergency beacon mark was not attached to the submarine during the first year. It must have been cut close to the accident time. Information technology is not out of question that the radio station in Nicosia really did receive the emergency call radioed by the emergency beacon. It so took most of the passing year for the buoy to drift southeasterly management toward the eastern shores of the Mediterranean.
A New Approach
After 25 arid search missions, the CIC of the Navy, Admiral Alex Tal dismissed the previous search committee and nominated Rear Admiral(ret.) Gideon Raz as head of the new committee. All previous search missions concentrated in relatively shallow waters according to the beacon inquiry conclusions. This time, Raz and his committee members consulted with United states Navy experts and scientists of deep h2o research. Based on new deep water technology, satellite advanced applied science and calcified information obtained from the U.s.a. Navy about the Mediterranean currents, led to a new conclusion.

It was decided to concentrate the search efforts along the path of the original route. The American marine contractor Nauticos Corporation was hired with Tom Dettweiler as trek leader and at the end of April 1999 the 26th attempt to find the lost submarine was launched.
The 26th Search Expedition is on
On 9 May 1999 the two charted sea vessels arrived at the search area. The designated search frames box area was approximately 60 nautical miles long, about 8 nautical miles wide and contained 16 search lanes. With a speed of 2 knots per hour it takes between 30 to 40 hours to monitor the ocean bed of each search lane.
Searching was conducted using the AMS-60, a wide-swath sonar and the REMORA 6000, a remotely operated vehicle (ROV) equipped with both video and withal cameras.

| REMORA 6000, a remotely operated vehicle (ROV) equipped with both video and still cameras, was used to verify the sonar contacts and identify the DAKAR | AMS-60 sonar search system used to locate the Dakar. Nauticos and Williamson personnel operated this organization twenty-four hours per day during at-sea operations. |
Dakar is found
At the evening of the 24th May the sonar detected the presence of a large body resting on the seabed. The team was able to view on the monitor a big black spot and a handful of smaller dots around it. Dettweiler ordered to winch down the ROV, a remotely operated vehicle equipped with both video and all the same cameras, in club to deport a more specific visual survey and make a positive identification. Bad weather condition delayed the investigation for another 3 days. At 0700, on May 28th the ROV dove and 4 hours subsequently information technology started to transmit pictures to the ship 2900 meters to a higher place. There was no place for doubt. It was articulate that those are the remains of a submarine. The submarine rests on her keel, her bow points to the northwest, the hull is broken in two between the engine room and the stern. The conning tower is ripped off and on its side, every bit the forrard part of the belfry(the span)lies 230 meters away. The stern of the submarine, with its propellers and dive planes, broke off the submarine and rests non far from the master hull.

Navy headquarters in Tel-Aviv was informed of the finding on Friday May 28thursday. As the bottom of the Mediterranean is a graveyard for many German, Italian and British WWII submarines, a team of three erstwhile commanders of submarine squadron were rushed to the search expanse on the deck of a fast missile boat. Rear Admiral Raz, Commander Amir and Commander Keisari carefully examined the video pic, searching for details characteristic of the Israeli "T" class boats. A few hours afterwards they gave the last confirmation that the lost submarine, INS Dakar had finally been found. It was Friday, Sabbath'due south eve, and at 8:00 PM, all news broadcasting started with the words that sent a shiver through the nation:
INS Dakar was found
500 kilometers (310 miles or 270 body of water miles) away from the shores of State of israel, on the bed of the Mediterranean, in 2,900 meters of waters (ix,514 feet), the Dakar rests.

What happened to Dakar?
Afterward the finding of the Dakar, and about a year later on the salvage of the span, the mystery of the INS Dakar was solved.
Nosotros will never know exactly what has happened on the night between the 24th and the 25th of January 1968, but according to what was found we tin get equally shut to the truth as possible: ane. Information technology happened between midnight and 3am. The boat was traveling at a speed of 8.5 knots, submerged, snorkeling and in direct drive.
2. In straight drive the diesel engines non only charge the batteries merely also plough the 2 propellers.
3. For an unknown reason a small-scale leak of water starts at ane of the forwards sections. This leak of water impairs the balance of the submarine and she loses her trim.
4. Because of the speed momentum the submarine goes into a steep, fast swoop. The fact that the diesels are engaged with the electrical motors prevents an "all astern" maneuver which might take avoided the tragedy that followed.
v. Within 30 seconds the Dakar reaches information technology's crash depth and starts to implode.
6. The implosion happens fast and rips all forth the hull with a tremendous power. The expiry of the boat and her crew is instant, fast and violent.
7. During the implosion the stern emergency buoy breaks loose and makes its way to the surface. However, it drags along with it the 600 ft long steel cablevision and a heavy pulley. The weight of the cable and the pulley forestall the buoy from surfacing completely.
8. The Dakar, imploded and broken up, continues her dive to the depths of the Mediterranean. Within x-15 minuets she reaches the bottom of the sea and crashes with a huge impact. The crash separates the hull between the engine room and the stern compartment. This causes the broken stern to wing frontwards and state near the conning tower. Heavy parts fly in all directions, a huge cloud of sand rises for a long time, and when it settles downwards the deep silence dominates again the eternal silence of the sea.
