The SMU - 4 was a class U - 3 submarine built by Germaniawerft of Kiel. She was launched in November 1908 and was at the time
one of only four operational submarines in the Austrian-Hungarian U boat fleet.
During the first year of the war she was unsuccessful in attacking warships however capturing as prizes; several small vessels.
During September of 1914 U - 4's primary mission was reconnaissance patrols and was commanded by
Linienschiffsleutnant Hermann Jöstel
SMU - 4 sank 12 vessels totalling 18,264 tons.
3 ships (13 GRT) taken as prize (http://wapedia.mobi/en/Prize)

1 warship (5,400 GRT) damaged

SMU - 4 was the longest serving U - Boat of the Austrian-Hungarian submarine force.
In late November, U-4 seized the 13 ton Albanian sailing vessel Fiore del Mar as a prize off Montenegro.
U-4 received her first radio set the following month.
U-4's next success was the capture of three Montenegrin boats on 19 February 1915.
During April 1915, the boat was equipped with a 3.7-centimeter quick firing deck gun.
On 24 May, in the Gulf of Drin, U-4 unsuccessfully attacked an Italian Lombardia-class cruiser, but on 9 June 1915, Linienschiffsleutnant Singule spotted the British cruiser 'Dublin' escorting a convoy along the Montenegrin coast.

Despite a screen of six destroyers, U-4 was able to torpedo HMS 'Dublin' off San Giovanni de Medua. Twelve men on the HMS 'Dublin' died in the attack, but the cruiser made her way safely, although damaged, back to port. HMS Capt Kelly, steaming at high speed with strong escort of French and Italian destroyers off N Albanian coast afterbeing torpedoed near San Giovanni di Medua, soon worked up to 17kts, got back to Brindisi, but remained out of action for some time.

Italian armored cruiser 'Giuseppe Garibaldi'
In July 1915, U-4 observed an Italian squadron of ships shelling the railroads at Ragusa. Singule selected the Italian armored cruiser 'Giuseppe Garibaldi' as a target and torpedoed her. 'Giuseppe Garibaldi, at 7,234 tons, being the largest ship sunk by U-4—sank with a loss of 53 men; 525 men survived.
In August, U - 4 was sent out to search for her missing sister ship, U-3, which was overdue, and learned of U - 3 having been sunk on 13 August by the French destroyer 'Bisson'.
In November, U-4 made an unsuccessful attack on a British Topaze-class cruiser.
In early December, U-4 dispatched two small Albanian vessels in the Gulf of Drin. The 10 ton sailing vessel 'Papagallo' was sunk, and the 'Gjovadje' was taken as a prize.
New periscopes and a new gyrocompass were installed on U-4 later in the month.
On 3 January 1916, operating again near the Gulf of Drin, Singule and U-4 seized another Albanian sailing vessel, 'Halil', and sank two smaller boats.
In early February, U-4 sank the 475 ton French patrol vessel 'Jean Bart', 6 nautical miles southwest of Cape Laghi, off Durazzo.
Just five days later, U-4 made an unsuccessful attack on a British Birmingham-class cruiser.
Over 26 and 27 March, U-4 participated in a search for the lost Austro-Hungarian submarine U-24.
Three days later, U-4 sank the British schooner 'John Pritchard' Of Carnar with explosive charges off the island of Antipaxos.
In July, U-4 was outfitted with a new 66 mm deck gun, which equaled the main gun planned for the U-20 class, under construction at the time.
On 2 August, U-4 missed an Italian Nino Bixio-class cruiser in a torpedo attack, and three days later, was missed by two torpedoes in an attack by an enemy submarine.
A week later, U-4 successfully torpedoed and sank the Italian schooner 'Ponte Maria' off Brindisi and weathered another unsuccessful enemy submarine attack.
Two days later, on 14 August, U-4 closed out her busy month of August by attacking the British steamer 'Inverbervie' off Cape Nau.
Some two months later, U-4 sank the Italian tanker 'Margaretha'. Originally the J.M.Lennard & Sons ship, 'Atilla', went down without any reported loss of life on 13 October.
In early May 1917, U-4 sank the steamer 'Perseo', the second largest ship sunk in the Ionian Sea. Although 'Perseo' was serving as an Italian troop transport at the time, there are no reports of casualties in the 4 May attack.
In mid-May 1917, U-4 participated in a support role in a raid on the Otranto Barrage that precipitated the Battle of Otranto Straits. On the night of 14/15 May, the Austro-Hungarian cruisers 'Helgoland', 'Saida', and 'Novara' attacked the drifters that deployed the anti-submarine nets that formed part of the Barrage, sinking 14, damaging 5, and taking 72 prisoners.
Destroyers 'Csepel' and 'Balaton' were sent to simultaneously attack Italian transports shuttling between Italy and Valona, and sank an Italian destroyer and a munitions ship. U-4, which was posted near Valona, was a part of a force of three U-boats intended to intercept British and Italian ships responding to the attacks; the other two were the Austro-Hungarian U-27 and the German UC-25 .
A squadron of British cruisers and Italian and French destroyers joined the battle against the Austro-Hungarian cruisers on 15 May. Several ships on each side were damaged by the time the engagement was broken off. As a result of the attacks the drifter line of the Barrage was moved farther south and maintained only during the day, a success for the Central Powers.
U-4 did not take any offensive action during the raid and ensuing battle. On 30 May at Corfu, U-4 torpedoed and sank the French passenger steamer 'Italia', in operation by the French Navy as an armed boarding ship.
On 19 June, U-4 scored a triple victory when she sank the French steamers 'Edouarde Corbière' and 'Cefira' and the Greek ship 'Kerkyra' off Taranto. U-4 sank what would be her final ship on 12 July, when she torpedoed the French tug 'Berthilde' off Cape Stilo.
In September, U-4 received a new bulwark on her conning tower.
U-4 arrived at Pola for the final time on 1 November 1918 and was there at the war's end.
She was ceded to France as a war reparation and scrapped in 1920.
U-4 was the longest serving Austro-Hungarian submarine and sank a total of 18,264 ton s of enemy shipping during the war.

Kriegsmarine) during the First World War (http://en.wikipedia.org/wiki/First_World_War). The design for U-20 was based on submarines of the Royal Danish Navy (http://en.wikipedia.org/wiki/Royal_Danish_Navy)'s Havmanden class (http://en.wikipedia.org/wiki/Havmanden_class_submarine_%281911%29) (three of which had been built in Austria-Hungary (http://en.wikipedia.org/wiki/Austria-Hungary)), and was largely obsolete by the beginning of the war.

U-20 had no wartime successes and was sunk in early July 1918 by the Italian submarine F-12 (http://en.wikipedia.org/w/index.php?title=Italian_submarine_F-12&action=edit&redlink=1). The wreck of U-20 was located in 1962 and salvaged.

Design and construction

When it became apparent to the Austro-Hungarian Navy (http://en.wikipedia.org/wiki/Austro-Hungarian_Navy) that the First World War (http://en.wikipedia.org/wiki/First_World_War) would not be a short war,[1] (http://en.wikipedia.org/wiki/SM_U-20_%28Austria-Hungary%29#cite_note-Hal-382-0) they moved to bolster their U-boat fleet by seizing the plans for Denmark's Havmanden class submarines (http://en.wikipedia.org/wiki/Havmanden_class_submarine_%281911%29),[7] (http://en.wikipedia.org/wiki/SM_U-20_%28Austria-Hungary%29#cite_note-Con-344-6) three of which had been built at Whitehead & Co. (http://en.wikipedia.org/wiki/Whitehead_%26_Co.) in Fiume (http://en.wikipedia.org/wiki/Fiume).[6] (http://en.wikipedia.org/wiki/SM_U-20_%28Austria-Hungary%29#cite_note-Con-354-5) Although the Austro-Hungarian Navy was not happy with the design, which was largely obsolete,[8] (http://en.wikipedia.org/wiki/SM_U-20_%28Austria-Hungary%29#cite_note-Hal-383-7)[9] (http://en.wikipedia.org/wiki/SM_U-20_%28Austria-Hungary%29#cite_note-Con-341-8) it was the only design for which plans were available and which could be begun immediately in domestic shipyards.[9] (http://en.wikipedia.org/wiki/SM_U-20_%28Austria-Hungary%29#cite_note-Con-341-8) The Austro-Hungarian Navy unenthusiastically placed orders for U-20 and her three sister boats (http://en.wikipedia.org/wiki/Sister_ship) on 27 March 1915.[1] (http://en.wikipedia.org/wiki/SM_U-20_%28Austria-Hungary%29#cite_note-Hal-382-0)
U-20 was one of two boats of the class to be built at the Pola Navy Yard (http://en.wikipedia.org/w/index.php?title=Pola_Navy_Yard&action=edit&redlink=1).[7] (http://en.wikipedia.org/wiki/SM_U-20_%28Austria-Hungary%29#cite_note-Con-344-6) Due to demands by the Hungarian government,[1] (http://en.wikipedia.org/wiki/SM_U-20_%28Austria-Hungary%29#cite_note-Hal-382-0) subcontracts for the class were divided between Hungarian and Austrian firms,[2] (http://en.wikipedia.org/wiki/SM_U-20_%28Austria-Hungary%29#cite_note-Con-343-1) but this politically expedient solution worsened technical problems with the design and resulted in numerous modifications and delays for the class in general.[7] (http://en.wikipedia.org/wiki/SM_U-20_%28Austria-Hungary%29#cite_note-Con-344-6)
U-20 was an ocean-going submarine that displaced 173 tonnes (191 short tons) surfaced and 210 tonnes (231 short tons) submerged and was designed for a complement of 18. She was 127 feet 2 inches (38.76 m) long with a beam (http://en.wikipedia.org/wiki/Beam_%28nautical%29) of 13 feet (4.0 m) and a draft (http://en.wikipedia.org/wiki/Draft_%28hull%29) of 9 feet (2.7 m). For propulsion, she featured a single propeller shaft (http://en.wikipedia.org/wiki/Propeller_shaft), a single 450 bhp (340 kW) diesel engine (http://en.wikipedia.org/wiki/Diesel_engine) for surface running, and a single 160 shp (120 kW) electric motor for submerged travel.[2] (http://en.wikipedia.org/wiki/SM_U-20_%28Austria-Hungary%29#cite_note-Con-343-1) She was capable of 12 knots (22 km/h) while surfaced and 9 knots (17 km/h) while submerged. Although there is no specific notation of a range for U-20, the Havmanden class, upon which the U-20 class was based, had a range of 1,400 nautical miles (2,600 km) at 10 knots (19 km/h), surfaced, and 23 nautical miles (43 km) at 8 knots (15 km/h) submerged.[6] (http://en.wikipedia.org/wiki/SM_U-20_%28Austria-Hungary%29#cite_note-Con-354-5)
U-20 was armed with two 45 cm (17.7 in) torpedo tubes located in the front and carried a complement of two torpedoes. She was also equipped with a 66 mm/26 (2.6 in) deck gun (http://en.wikipedia.org/wiki/Deck_gun) and an 8 mm (0.31 in) machine gun (http://en.wikipedia.org/wiki/Machine_gun).[2] (http://en.wikipedia.org/wiki/SM_U-20_%28Austria-Hungary%29#cite_note-Con-343-1)
U-20 was laid down (http://en.wikipedia.org/wiki/Keel_laying) on 29 September 1915,[3] (http://en.wikipedia.org/wiki/SM_U-20_%28Austria-Hungary%29#cite_note-Tengeral-2) six months after she was ordered,[1] (http://en.wikipedia.org/wiki/SM_U-20_%28Austria-Hungary%29#cite_note-Hal-382-0) and was launched (http://en.wikipedia.org/wiki/Launch_%28ship%29) on 18 September 1916.[2] (http://en.wikipedia.org/wiki/SM_U-20_%28Austria-Hungary%29#cite_note-Con-343-1)
Service career

Upon completion, U-20 began diving trials. On her 15 March 1917 trial, she was accidentally rammed by Admiral Spaun (http://en.wikipedia.org/wiki/SMS_Admiral_Spaun) in the Fasana Channel (http://en.wikipedia.org/wiki/Fasana). The collision with the Austro-Hungarian light cruiser (http://en.wikipedia.org/wiki/Light_cruiser) twisted U-20's periscope (http://en.wikipedia.org/wiki/Periscope), extensively damaged the conning tower (http://en.wikipedia.org/wiki/Conning_tower), and knocked off her deck gun. After seven months of reconstruction, U-20 was commissioned (http://en.wikipedia.org/wiki/Commission_%28ship%29) into the Austro-Hungarian Navy on 20 October.[3] (http://en.wikipedia.org/wiki/SM_U-20_%28Austria-Hungary%29#cite_note-Tengeral-2)

After initially operating out of Pola, U-20 was transferred to Trieste (http://en.wikipedia.org/wiki/Trieste) in February 1918. Over the next three months, the U-boat patrolled in the northern Adriatic (http://en.wikipedia.org/wiki/Adriatic) between the Tagliamento estuary (http://en.wikipedia.org/wiki/Tagliamento) and Venice (http://en.wikipedia.org/wiki/Venice). U-20 had an encounter with an enemy submarine on 7 April but was not able to successfully launch an attack.[3] (http://en.wikipedia.org/wiki/SM_U-20_%28Austria-Hungary%29#cite_note-Tengeral-2)
On 3 July, Linienschiffsleutnant (http://en.wikipedia.org/wiki/Linienschiffsleutnant) Ludwig Müller sailed U-20 out from Trieste for the Gulf of Venice (http://en.wikipedia.org/wiki/Gulf_of_Venice). A day later, U-20 was spotted by the Italian submarine F-12 (http://en.wikipedia.org/w/index.php?title=Italian_submarine_F-12&action=edit&redlink=1), which was on patrol in the northern Adriatic. F-12 initially pursued U-20 underwater, and then on the surface. At a range of 650 yards (590 m), F-12 torpedoed U-20 at position 45°29′N 13°05′E (http://toolserver.org/%7Egeohack/geohack.php?pagename=SM_U-20_%28Austria-Hungary%29&params=45_29_N_13_05_E_scale:1000000&title=SM+U-20), sinking her with all hands. There was no wreckage on the surface, only an oil slick.[4] (http://en.wikipedia.org/wiki/SM_U-20_%28Austria-Hungary%29#cite_note-Grant-163-3)[Note 1] (http://en.wikipedia.org/wiki/SM_U-20_%28Austria-Hungary%29#cite_note-9) Like all of her sister boats,[7] (http://en.wikipedia.org/wiki/SM_U-20_%28Austria-Hungary%29#cite_note-Con-344-6) U-20 had no wartime successes.[5] (http://en.wikipedia.org/wiki/SM_U-20_%28Austria-Hungary%29#cite_note-KUK-U-20-4)
In mid 1962, the wreck of U-20 was discovered in the northern Adriatic. Italian salvage crews raised the boat's rear portion on 22 July and her front section on 21 November.[4] (http://en.wikipedia.org/wiki/SM_U-20_%28Austria-Hungary%29#cite_note-Grant-163-3) The conning tower (http://en.wikipedia.org/wiki/Conning_tower) and a small midships section of U-20 were donated to the Heeresgeschichtliches Museum (http://en.wikipedia.org/wiki/Heeresgeschichtliches_Museum) in Vienna (http://en.wikipedia.org/wiki/Vienna), where they are on display, while the rest of the boat was scrapped.[7] (http://en.wikipedia.org/wiki/SM_U-20_%28Austria-Hungary%29#cite_note-Con-344-6) The remains of the crewmen were buried on the grounds of the Theresian Military Academy (http://en.wikipedia.org/wiki/Theresian_Military_Academy) at Wiener Neustadt (http://en.wikipedia.org/wiki/Wiener_Neustadt).[10] (http://en.wikipedia.org/wiki/SM_U-20_%28Austria-Hungary%29#cite_note-BS-10)
