Navigating excellence: U-35’s general characteristics and resilient service in the German Navy

U-35 (S185), a Type 212A submarine in the German Navy, is a representation of Germany’s naval innovation. With an MTU diesel engine, a Siemens Permasyn electric motor, and powerful weaponry, it was introduced in 2015 and represents the latest in technology.

The fifth submarine of its class to be put into service is the German Navy’s Type 212A submarine, U-35 (S185). Howaldtswerke in Kiel started building the submarine in August 2007, and its debut in November 2011 marked a major turning point in the project. On March 23, 2015, U-35 was formally put into service after extensive testing and preparation.

This Type 212A class submarine is a prime example of Germany’s technological prowess and dedication to naval innovation and defence capabilities. Modern improvements and capabilities enable the ship to function as an important part of the German Navy with greater effectiveness.

Since it is run under the direction of the Rhineland-Palatinate city of Zweibrücken, U-35 has a unique relationship with this place. Sigrid Hubert-Reichling, the wife of Zweibrücken’s Lord Mayor Helmut Reichling, is the submarine’s patron. This relationship promotes a sense of civic pride and responsibility by highlighting the close relationships that exist between the German Navy and the communities it serves.

General Characteristics:

Under the Type 212 class, the German submarine U-35 (S185) is categorised as a submarine. Its lengths for the first batch are 56 m (183.7 ft) and the second batch is 57.2 m (187.66 ft). Its displacement is 1,450 tonnes (1,430 long tonnes) when it is surfaced and 1,830 tonnes (1,800 long tonnes) when it is submerged. There is a 6 m (19.68 ft) draft and a 7 m (22.96 ft) beam.

The propulsion system of the submarine is made up of a Siemens Permasyn electric motor (Type FR6439-3900KW), a single MTU 16V 396 diesel engine, and a seven-bladed skewback propeller that is powered by a Siemens Permasyn electric motor with 1700 kW. The U-35 can go at up to 12 knots when above water and 20 knots (37 km/h) when submerged.

When surfacing, the submarine can go 8,000 nautical miles (14,800 km or 9,196 miles) at a speed of 8 knots (15 km/h). Its total endurance is 12 weeks, and it can run for 3 weeks without the need for snorkelling. The U-35 can test at depths greater than 700 metres (2,296 feet).

Fifty-two men and five officers make up the U-35 crew. CSU 90 (DBQS-40FTC), ISUS90-20 Sonar, and Kelvin Hughes Type 1007 I-band navigation radar are among the sensors and processing equipment that are installed on the submarine. An EADS FL 1800U suite is available for electronic warfare and decoys.

Two groups of three 533 mm torpedo tubes each, pointing forward, make up the U-35’s armament. In addition to IDAS missiles, it is capable of deploying 24 external naval mines and carrying 13 DM2A4 and A184 Mod. 3 black shark torpedoes. 


1st Ubootgeschwader, which is based at Eckernförde, comprises the German submarine U-35 (S185). Prominent problems found with U-35 and its sister submarine, U-36, were reported in a January 2015 report published in Der Spiegel. There were some operational issues with this class of submarine, as evidenced by the various failures found in the radio buoy, radar, drive shaft system, and batteries.

The ThyssenKrupp Marine Systems yard in Kiel examined U-35 in October 2017. This inspection was necessary since the submarine broke its rudder in the Kattegat off Kristiansand while doing deep water testing. U-35 had been performing operational testing in Norwegian waters until October 15, 2017, before this incident.

U-35 participated in Operation Irini from June 12, 2021, to December 14, 2021. This operational engagement highlighted the submarine’s importance in maritime security and peacekeeping by showcasing its involvement in international efforts. The information provided does not go into detail about U-35’s specific contributions or role during Operation Irini.

The German Navy’s continued dedication to maritime security and international collaboration is demonstrated by the U-35’s continued participation in a variety of operational actions, even in the face of obstacles and required inspections.
