Armament

SM U-29 or U-XXIX was a U-27 class U-boat or submarine for the Austro-Hungarian Navy. U-29, built by the Hungarian firm of Ganz Danubius at Fiume, was launched in October 1916 and commissioned in January 1917.

U-29 had a single hull and was just over 121 feet (37 m) in length. She displaced nearly 265 metric tons (261 long tons) when surfaced and over 300 metric tons (295 long tons) when submerged. Her two diesel engines moved her at up to 9 knots (17 km/h) on the surface, while her twin electric motors propelled her at up to 7.5 knots (13.9 km/h) while underwater. She was armed with two bow torpedo tubes and could carry a load of up to four torpedoes. She was also equipped with a 75 mm (3.0 in) deck gun and a machine gun.

During her service career, U-29 sank three ships and damaged one warship, sending a combined tonnage of 14,784 to the bottom. U-29 was at Fiume at war's end and was surrendered at Venice in March 1919. She was granted to France as war reparation in 1920, but foundered while under tow to Bizerta for scrapping.[5]
