The Ula class is a Norwegian submarine type which was assembled in Germany in the late 1980s and early 1990s. The class, consisting of six vessels, is currently the only submarine type in service with the Royal Norwegian Navy.
History
The ordering of a new Norwegian submersible design stemmed from a 1972 decision to modernise the Royal Norwegian Navy (RNoN) submarine flotilla, which then consisted of the aging Kobben-class submarines. The contract was signed on 30 September 1982 for six boats with Thyssen Nordseewerke, Emden. An option for two more submarines was included in the original deal, however, it was never picked up.[4]
The construction of the vessels was an international project. The combat systems were made in Norway by Kongsberg, the attack sonar is German and the flank sonars French. The hull sections were produced in Norway and assembled in Germany by Thyssen Nordseewerke. In Germany, the design is known as the U-Boot-Klasse 210.
When commissioned, the Ulas were the first Norwegian submarines to have enough bunks for the entire crew and a shower.[1]
The Ula-class submarines are among the most silent and maneuverable submarines in the world. This, in combination with their relatively small size, makes them difficult to detect from surface vessels and ideal for operations in coastal areas. The Ula class is regarded as both the most effective and cost-effective weapons in the RNoN.[citation needed]
Ship history
In 1989, while undergoing trials, Ula was damaged by a practice torpedo. In March 1991, Uredd was involved in an accident while docking. In February 1992, Uredd suffered a control room fire.[4]
In recent years, several submarines of the Ula class have been deployed in the
Future submarine capability
During 2006-2008 the Ula class was slated for modernisation. Most notably, new communication equipment (
In 2012 the Norwegian MoD set 2014 as a deadline for deciding whether to further extend the operative life of the Ula class after their slated end-of-life in 2020, or to replace them with a new fleet.[8] In December 2014, the Norwegian Ministry of Defence made the decision to begin the process of replacing the Ulas. As part of that decision, the Ula-class submarines would be kept in service for a further five years, but would not exceed 35 years total service as that would be too costly.[9] Given the delay in replacing the Ula-class, it was subsequently decided to further life-extend the Ula-class through the 2020s until a new class of submarines entered service.[10]
In 2016, two suppliers (DCNS and Thyssen Krupp) were shortlisted to provide competing options to replace the Ula-class boats. In February 2017, Thyssen Krupp was selected to provide four replacement submarines based on the
