Subsequent searches of the wreckage with American equipment(from May 8 to 21, 1970)

The disappearance of the Eurydice submarine on March 4, 1970 unfortunately raised the problem of deep intervention means. At the time the US had a specialized vessel, the Mizar (Tagor.II) belonging to the Naval Research Laboratory. At the request of France, this building is leased to the Navy. The Mizar then interrupted its major refit work and reached Toulon on April 9.

It is a former 4500 ton icebreaker, heavy and stable with a central pit for maneuvering a “ poisson ” equipped with cameras.

​

The research is being carried out from April 12 to May 2 with an American NRL team joined by a French submariner officer, the LV Brute de Remur. After raking 3 areas totaling an area of 13.5 N2, the wreckage of the Euridyce is located 3700 meters or 2 N from the shaking point calculated by Professor Rocard (the same as the one mentioned in the committee of inquiry tab) cc781905-5cde-3194-bb3b-136bad5cf58d_March 4, 1970.

 

All the debris lies within a circle 120 meters in diameter. The submarine itself is planted at 30 degrees in a 45 degree angled sediment slope. Its list is 100 degrees. Only the rear part emerges over a length of 13 meters.

 

After such results, it is decided to use the Mizar's rental time tester to search for the Minerva.

The area to be explored is a square with a side of 12 N, ie a surface of 144 N 2, that is to say 10 times larger than for the Eurydice. For the search for Scorpion, the area had the same surface and it took 237 days of research, including 147 with MIZAR. For La Minerve there were only 22 days left.

From May 8 to 21, a square of 4 N, i.e. 16 N2, a été swept. The 80,000 photos taken gave no indication of Minerva. They made it possible to distinguish large erratic blocks and to see the wreckage of an aircraft carrier.
