HMS Perseus, 79 metres long, 8.5 metres beam and 4.17 metres draught submarine was laid down on 2 July 1928. She had a displacement of 1,475 long tons surfaced, and 2,040 long tons submerged. Fitted with four-stroke blast injection eight-cylinder diesels, accommodated in the larger engine room and designed to develop a total of 4640 bhp. Surface speed 17.5 knots and 8.6 knots when submerged. Like all other Parthian Classes submarines, it was designed to dive to a depth of 500 feet.
During World War II, in 1941 she was operating in the Mediterranean Sea. On December 6th, 1941 HMS Perseus had struck an Italian mine on the starboard side forward, and sank quickly.
She sunk seven nautical miles north of Zante (Zakinthos) Island, west coast of Greece in the Ionian Sea in position 37◦ 54’N, 20◦ 54’E.
The “Perseus” wreck is 52 meters deep, “shallow” by standards of the team of U-Boat Navigator. This object is new for us, and we do dives, submersions and shooting here for the first time, using everything we’ve got: divers, ROV (Ageotec Perseo GTV remotely operated underwater vehicle) and submarine Triton 3300/3.
