The discovery made by the Cacciamine Vieste of the Navy thanks to the sophisticated equipment supplied
The Vieste minesweeper of the Navy, during a technical verification and surveillance of the seabed in the Tyrrhenian Sea at the island of Stromboli, found the wreck of the Light Cruiser Giovanni Delle Bande Nere sunk in 1942.
The wreck was located and identified about 11 nautical miles south of the island of Stromboli at a depth between 1460 and 1730 meters, in a position compatible with that of its sinking on April 1, 1942, while it was in transfer. from Messina to La Spezia, to carry out some repairs in the Arsenal escorted by the destroyer Aviere and the torpedo boat Libra. During the voyage, at about 09.00, he was hit by two torpedoes launched by the British submarine HMS Urge. The cruiser, broken into several sections, quickly sank. Most of the crew died in the event.
The discovery took place thanks to the use of underwater vehicles embarked on the Vieste minesweeper capable of conducting research and identification at deep altitudes: the autonomous underwater vehicle (Autonomous Underwater Vehicle - AUV) Hugin 1000, of the Kongsberg company, and the Multipluto 03 wire-guided vehicle. , of the company GAY Marine. Having circumscribed the search area based on the presumed coordinates of the sinking, the minesweeper proceeded to map the seabed with the Hugin vehicle, discovering more contacts that could be correlated with the wreck. Subsequently the contacts were identified thanks to the use of the Multipluto, which made it possible to film the first images of the ship, revealing the three sections in which it broke in the sinking and ascertaining its identity.
The discovery of the Light Cruiser Giovanni Delle Bande Nere confirms the operational effectiveness of the underwater vehicles supplied to the Navy, capable of operating at deep altitudes for the control of the seabed and strategic infrastructures, as well as the professionalism of the specialists of the Command of the Mine countermeasures. Underwater vehicles represent a fundamental asset for maintaining high capacity of the mine countermeasures component by increasing the altitude and the possibility of detecting and identifying risk situations in deep waters.
