HISTORY OF THE SHIPWRECK. Built by Cammell Laird & Co of Birkenhead in the UK and launched on November 11, 1942, the HMS Stubborn ("stubborn" - in English) was an S-class submarine 'P238' and is 66 meters long. It had a crew of 44-48 under Lieutenant Duff, and later in 1944, under Lieutenant Davies. HMS Stubborn served in the North Sea and the Baltic Sea and had a very difficult time in these cold waters.

HMS Stubborn was sunk on purpose to be used in training naval officers in the handling of the ASDIC sonar, used in World War II by the British to detect the presence of German submarines.

It's in superb condition, lying upright on the starboard side. All three escape hatches open and you can see the torpedo tubes and propellers still there. The top of the wreck is 45 meters and the bottom is 55 m.

HMS Stubborn sailed to Malta for the first time on its route to the Suez Canal and eventually to the Pacific, where it carried out patrol duties in its fight against the Imperial Japanese Navy. It was at this stage that it suffered the worst attack of the war. Lost tail fin and rudder. This loss was caused by depth charges, but mainly by hitting the sea floor at 166 meters when it was only designed to descend to a maximum depth of 90 meters!

Returning to Malta for the second and last time and as it was in no condition to repair itself, the submarine was stripped of all important equipment, instruments, armaments and periscope removed before being sent to its final grave.
