French submarine Eurydice explodes underwater, resulting in the loss of the entire 57-man crew.
Eurydice was a French submarine, one of eleven of the Daphné class.
On 4 March 1970, while diving in calm seas off Cape Camarat in the Mediterranean, 35 miles (56 km) east of Toulon, a geophysical laboratory picked up the shock waves of an underwater explosion. French and Italian search teams found an oil slick and a few bits of debris, including a part that bore the name Eurydice.
The cause of the explosion was never determined. All 57 crew were lost.
The USNS Mizar took part in a search for the missing Eurydice and on 22 April 1970 they discovered several large pieces of wreckage in depths from 600 to 1,100 metres (2,000 to 3,600 ft) off Cape Camarat near Saint-Tropez.
