Tyr's name is preserved in Tuesday. He is the god of martial honor (compare the German Zier). Tyr is the most daring and intrepid of all the gods. It is he who dispenses valor in war: hence warriors do well to invoke him. It has become proverbial to say of a man who surpasses all others in valor, that he is Tyr-strong, or valiant as Tyr. A man noted for his wisdom is also said to be wise as Tyr.

He gave a splendid proof of his intrepidity when the gods try to persuade the wolf Fenrer to let himself be bound up with the chain Gleipner. The wolf fearing that the gods would never afterwards unloose him, consented to be bound only on the condition that while they were chaining him he should keep Tyr's hand between his jaws. Tyr did not hesitate to put his hand in the monster's mouth, but when the Fenriswolf perceived that the gods had no intention to unchain him, he bit the hand off at that point which has ever since been called the wolfs joint (ulfliir), the wrist. From that time Tyr had but one hand.

Tyr is the son of Odin, and it is through him the latter, as the god of war, awakens wild courage. Thus he is the god of honor, and when the noble gods desire to tame the raging flames he naturally has to arouse all his courage and even sacrifice a part of himself, just as people frequently have to sacrifice some comforts to keep clear of rogues and scoundrels.

KNM Tyr is the Navy's special vessel for deep underwater operations. The vessel puts out training mines and reports them in connection with national and international exercises. The vessel is equipped with a mini-boat that can be operated down to 1000 m. It is called Remotely Operated Vehicle (ROV) and is used for seabed search, inspection and filming of subsea installations, as well as performing various operations such as raising objects from the seabed. KNM Tyr is also part of the national submarine preparedness.

The vessel was acquired by the Navy in the autumn of 1993 to replace the mining vessel KNM Borgen. The vessel was built at Voldnes Shipyard in Ålesund in 1981. Until the Navy assumed the vessel served it as a standby vessel in the North Sea under the name M / S Standby Master.

From 1994 the vessel underwent extensive rebuilding and modernization at the Mjellem and Karlsen workshop in Bergen. The vessel installed new water pump and side windows in addition to new side windows aft. Furthermore, the bridge was expanded, the mine trailer was built on aft deck and new hydraulic equipment was installed on the working deck. The vessel was also installed dynamic positioning equipment / tactical system and was also equipped with a Remotely Operated Vehicle (ROV).The decor was also modernized.

With this, KNM Tyr has become a modern and exciting vessel that the Navy uses for a variety of different purposes. The Navy commanded for the first time on March 7, 1995 and has since performed a number of different missions. Outside the Navy, bodies such as customs, police, the state pollution control, the Institute of Marine Research and the Norwegian Defense Research Institute are examples of principals who often use the vessel. Some of the assignments to KNM Tyr have received great media attention.

  • Find and locate "Scharnhorst" in collaboration with NRK Focal Point.

KNM Tyr is equipped with a dynamic positioning system (DP) attached to a variety of sensors for precise measurement of position and external conditions such as wind, power etc. All of the propeller propellers can be computer controlled by this system and it has the capacity to hold the vessel In calm winds and high seas with an accuracy of up to two meters, depending on the sensors used.

The vessel is further equipped with a map chart in WGS-84 for the entire coast of Norway, as well as detailed bottom maps for certain areas. On this display, the crew can plot positions and movements for own vessels, ROVs, divers and the like in two or three dimensions.
