INS Dakar (Z-77) was purchased by Israel from the British Navy with its sister submarine, "Leviathan." It was repaired at the Portsmouth Yards, manned by an Israeli crew trained by the British Navy and left for Israel on January 9, 1968. On January 25 Dakar and her 69 man crew were lost for an unknown reason.
The submarine's last location was reported on 24, January at 06:00 south of the eastern tip of the island Crete, and the last radio transmission was received 18 hours later. Despite extensive searches carried by ships, submarines and aircraft, Dakar was not found and was declared lost.
A year later, one of Dakar's emergency buoys was found on the Gaza Strip coast. Wrong findings from the analysis of the location of the buoy led to searched on Egypt's coast and the Aegean Sea, in vain. On May 28, 1999, 31 years and four months after its disappearance Dakar wreckage was found between the islands of Cyprus and Crete, by a searching vessel belonging to the company Nauticus.
