SM UC-3 - German submarine mines from the period of World War I. He was the third ship of type UC I. Built in the Vulcan shipyard in Hamburg, the ship was launched on May 28, 1915, and was commissioned at Kaiserliche Marine on June 1, 1915. During his service, the SM UC-3 carried out 29 combat patrols, during which he placed many mine pens, which sank 19 vessels with a total capacity of 29 021 BRT, 3 ships with a total displacement of 1571 tons, while 2 ships with a total capacity of 1909 BRT were damaged . She sank with all her crew on May 27, 1916, on a mine north of Zeebrugge.

Design and tactical-technical data The successes of the first German U-boats at the beginning of World War I (including the sinking of the British armored cruisers HMS "Aboukir", "Hogue" and "Cressy" by the U-9) led the Imperial Navy to Admiral Tirpitz for activities aimed at the construction of new types of submarines. Appreciating the importance of the mine war, on 9 October 1914, the ministry approved the project of a small underwater ministry developed by the Torpedo Inspectorate under Dr Werner, later designated as UC I.

SM UC-3 was a small, single-hull coastal submarine whose design was based on the design of UB I units. The total length was 33.99 meters, the width was 3.15 meters and the draft was 3.04 meters. The height (from the keel to the top of the kiosk) was 6.3 meters. The displacement at the surface was 168 tons and the immersion was 183 tons. The unit had a rounded beak and a cylindrical 1.3m diameter kiosk enclosed by a streamlined cover, and there were two gaps in its interior: one in the kiosk and the other in the aft part leading to the crew room. The ship was propelled on the surface by a six-cylinder, Daimler RS166 four-stroke diesel engine with a horsepower of 90 horsepower (HP), and under the water was moving thanks to an electric engine SSW 175 hp. Moving one three-blade, bronze screw (1.8 m in diameter and 0.43 m in pitch), the propulsion system provided a velocity of 6.2 knots on the surface and a 5.22 knot in immersion (using the surface of the electric motor the ship was able to achieve 7,5 knots). The range was 780 Mm at 5 knots in water and 50 Mm at 4 knots under water. The ship took 3.5 tons of diesel and the electricity was stored in 112-cell batteries of 4,000 Ah capacity which provided 3 hours of underwater swimming at full load.

The ship had two internal ballast tanks. The maximum submersion depth was 50 meters and the draft time was 23-36 seconds. The ship had no torpedo or artillery armament, while in the bow section 12 anchor types UC / 120 in six 100mm diagonal mine shafts, one behind the other. axis of symmetry of the ship, at the angle of the rear (the way of putting - "under"). This system meant that mines had to be placed on the depth planned before the cruise, because there was no access to them at sea (also mine fuses had to be installed before sailing out, which was not a safe solution and caused the destruction of several units of this type). The armament was supplemented by one machine gun with ammunition reserves of 150 rounds. The ship had one Zeiss periscope. The anchor anchor was 136 kg. The crew consisted of 1 officer (commander) and 13 non-commissioned officers and sailors. Building

SM UC-3 was ordered on November 23, 1914 as the third of a series of 15 UC I ships (project number 35a, assigned by the Underwater Ship Inspectorate), as part of a war program to expand the fleet. Getting
