SM UB-79 was a German Type UB III submarine or U-boat in the German Imperial Navy (German: Kaiserliche Marine) during World War I. She was commissioned into the German Imperial Navy on 27 October 1917 as SM UB-79.[nb 1]

UB-79 was surrendered in accordance with the requirements of the Armistice with Germany on 26 November 1918 and broken up at Swansea in 1922.[2]

Construction[edit]

She was built by Blohm & Voss of Hamburg and following just under a year of construction, launched at Hamburg on 3 June 1917. UB-79 was commissioned later that same year under the command of Kptlt. Woldemar Petri. Like all Type UB III submarines, UB-79 carried 10 torpedoes and was armed with a 8.8 cm (3.46 in) deck gun. UB-79 would carry a crew of up to 3 officer and 31 men and had a cruising range of 8,680 nautical miles (16,080 km; 9,990 mi). UB-79 had a displacement of 516 t (508 long tons) while surfaced and 648 t (638 long tons) when submerged. Her engines enabled her to travel at 13.6 knots (25.2 km/h; 15.7 mph) when surfaced and 7.8 knots (14.4 km/h; 9.0 mph) when submerged.

Notes[edit]

  1. ^ "SM" stands for "Seiner Majestät" (English: His Majesty's) and combined with the U for Unterseeboot would be translated as His Majesty's Submarine.
