SM submarines

from Wikipedia, the free encyclopedia

SM submarines ( "SM" stands for "His Majesty") was the common name for the submarine creatures in the Imperial and Royal Navy Austria-Hungary . The almost identically named submarines of the German Empire can be found in this list .

Beginnings

The first submarines

In 1908 the first submarine of the Austro-Hungarian Navy, SM Unterseeboot 3 , was launched. Before that, three test boats of the types Simon Lake , Germania and John Philip Holland were built between 1907 and 1910 . From these, after thorough testing, the type that had proven itself best was selected. All boats were intended as coastal boats for the Adriatic region .

Three years later, in 1912, the fleet comprised the submarines U 1 and U 2 (outdated lake boats with petrol engines), U 3 and U 4 (Germania boats) and U 5 and U 6 (Dutch boats with petrol engines).

The submarine station in Pola with the mother ship SMS Pelikan was under the port admiral.

On the daily trips, the submarines were assigned certain areas. One boat went in the rayon south of Pola to Promontore, one in the Fasana Channel and the third submarine west of the Brion Islands . Every week, exercises were carried out in which SMS Gigant and SMS Spalato were used as target ships for torpedo fire.

The scope of these exercise drives was sufficient until the crews and staffs had retracted and the commanders had their boats completely under control. Soon, however, it was necessary to carry out advanced actions in order to gain experience of life on board the submarines and the behavior of the engines. However, the port admiral refused to do so. After long requests, the U 5 and U 6 boats were allowed to be sent to the Gulf of Cattaro . This trip was successful, and the commanders used every chance to carry out mock attacks on passing naval units and steamships .

Two smaller exercises took place in the waters off Lussin and in the Quaranero , which increased the motivation of the officers and crews and strengthened confidence in the boats. The targets were SMS Gigant in the first exercise and SMS Herkules in the second exercise.

At that time, the officer cadre comprised only six commanders, three reserve commanders and three other second officers . There was no special school for submarine officers.

Young frigate lieutenants were assigned to a reserve staff as second officers after a medical examination. They took part in all trips of the boat type in question and studied theory in the afternoon under the guidance of a reserve commander. When the opportunity arose, the frigate lieutenant was embarked as second officer. The second officer was then a candidate for the post of reserve commander. Theoretical and practical training was similar for teams.

After creating the position of a fleet inspector, the commander of the submarine station tried to arouse his interest in the submarines. After several presentations, the fleet inspector agreed to take part in a submarine trip on board U 5. This three-hour demonstration drive was held in the rayon west of Brioni, the function of the engines and the sequence of a diving maneuver were explained to the inspector. A one-hour dive trip with changing depths and the sham launch of a torpedo were carried out. The brevity, silence and precision in issuing and executing orders aroused great interest, so that Admiral Haus could only report positive things.

New buildings

Tower of the U 20 submarine , exhibited in the HGM

In 1912, the Germania shipyard in Kiel and the Whitehead factory in Fiume submitted projects for the construction of 1000 t boats. After a detailed study of the plans on the basis of experience with previous types, a program was drawn up for improvements in terms of speed, number of torpedo tubes and torpedoes, depth rudder, periscopes and ventilation. After discussions with the submarine commanders, the results of these findings were presented to the marine section.

After several meetings in the marine technical committee and in the marine section , in which representatives of both shipyards participated, the demands were confirmed by the marine section.

Museum reception

The only surviving fragments of a submarine of the Austro-Hungarian Navy are in the Army History Museum in Vienna. These are the tower and the pressure hull fragment of U 20 , which was attacked and sunk by an Italian submarine on July 6, 1918 in the area of ​​the Tagliamento estuary while its batteries were being charged and the associated inability to maneuver. In the course of time, the Tagliamento washed up a lot of river sand , which raised the wreckage of the boat more and more and thereby hindered fishing and navigation in the Tagliamento estuary. In 1962, the Republic of Italy decided to salvage the wreck, which broke apart when it was lifted at the points where torpedoes had hit. The tower and parts of the pressure hull were handed over to the Republic of Austria , restored and exhibited in the Army History Museum. The few human remains that came to light when the wreck was recovered were handed over to the Austrian Armed Forces , brought to Wiener Neustadt by Steyr-Puch Haflinger and buried in the cemetery of the Theresian Military Academy . A grave of honor marks this place.

In 2012 the Army History Museum received a bundle of photographs that document the recovery of the submarine in 1962, a selection of which is on display in the area of ​​the submarine. In addition, relics and equipment of the crew members recovered from U-20s can be seen.
