Question: What Navy commissioned the Metel, a fast naval ship carring torpedoes?
Context: A torpedo boat is a relatively small and fast naval ship designed to carry torpedoes into battle.  The first designs rammed enemy ships with explosive spar torpedoes, and later designs launched self-propelled Whitehead torpedoes.  They were created to counter battleships and other slow and heavily armed ships by using speed, agility, and the power of their torpedo weapons.  A number of inexpensive torpedo boats attacking en masse could overwhelm a larger ship's ability to fight them off using its large but cumbersome guns.  An inexpensive fleet of torpedo boats could pose a threat to much larger and more expensive fleets of capital ships, albeit only in the coastal areas to which their small size and limited fuel load restricted them. The Bliss-Leavitt Mark 9 torpedo was a Bliss-Leavitt torpedo developed and produced by the E. W. Bliss Company and the Naval Torpedo Station in Newport, Rhode Island in 1915.  The Mark 9 was originally intended to be used on battleships.  Before the Mark 9 could be issued, however, use of torpedoes on battleships was discontinued and Mark 9 torpedoes were placed in storage.  These torpedoes were modified for deployment on R-class and S-class submarines, and used in early World War II to supplement the initial supply of Mark 14 torpedoes.  Torpedo production for the U.S. Navy was terminated by the E.W. Bliss Company about 1920 after completion of the Mark 9 project. The lighthouse and naval vessel urban legend describes an encounter between a large naval ship and what at first appears to be another vessel, with which the ship is on a collision course.  The naval vessel, usually identified as of the United States Navy and generally described as a battleship or aircraft carrier, requests that the other ship change course.  The other party (generally identified as Canadian or often Irish and occasionally Spanish) responds that the naval vessel should change course, whereupon the captain of the naval vessel reiterates the demand, identifying himself and the ship he commands and sometimes making threats.  This elicits a response worded as "I'm a lighthouse.  Your call" (or similarly), a punchline which has become shorthand for the entire anecdote. Mühlhausen was a naval ship in service with the German Navy.  The ship was launched June 30, 1966 at the Burmester Werft in Bremen with the name "Walther von Ledebur".  She was a prototype of a new class of ocean-going minesweepers, which however was not accepted by the Bundesmarine.  She was commissioned in 1967 and served with a civilian crew as a trials ship for the "Wehrtechnische Dienststelle" (Defence Technology Agency) until decommissioning in 1994.  She had the pennant number A1410 and was categorized as a Type 742 class ship. Pohjanmaa is a former minelayer of the Finnish Navy.  The sole member of her class, she was the flagship of the Finnish Navy as well as the largest naval ship in service in Finland until 2013.  The ship has an Finnish-Swedish ice class 1A so she can operate all year round.  During a crisis, the main task for "Pohjanmaa" would have been mine laying and acting as a command ship.  She also acted as a school ship for the Naval Academy cadets.  Part of their training includes an annual cruise abroad. ""Metel"" (from Russian: "Метель" - "Blizzard") was a Guards Torpedo boat, Storm class, of the Soviet Navy.  Commissioned in 1934, it was attached to the Pacific Fleet.  During World War II the ship fought mainly against the Imperial Japanese Navy in the Far East.  On August 26, 1945 it acquired guards status and the ship's commander, Captain-Lieutenant L. N. Balyakin, was awarded the Hero of the Soviet Union on September 14. USNS "Marine Adder" (T-AP–193) was a troop ship for the United States Navy in the 1950s.  She was built in 1945 for the United States Maritime Commission as SS "Marine Adder, a Type C4-S-A3 troop ship, by the Kaiser Company during World War II.  In 1950, the ship was transferred to the Military Sea Transport Service of the U.S. Navy as a United States Naval Ship staffed by a civilian crew.  After ending her naval service in 1957, she entered the National Defense Reserve Fleet, but was sold for commercial use in 1967.  Renamed SS "Transcolorado, she was chartered by the Military Sealift Command as a civilian cargo ship designated T-AK-2005. The names of commissioned ships of the United States Navy all start with USS, for "United States Ship".  Non-commissioned, primarily civilian-manned vessels of the U.S. Navy under the Military Sealift Command have names that begin with USNS, standing for "United States Naval Ship".  A letter-based hull classification symbol is used to designate a vessel's type.  The names of ships are selected by the Secretary of the Navy.  The names are those of states, cities, towns, important persons, important locations, famous battles, fish, and ideals.  Usually, different types of ships have names originated from different types of sources. United States Ship (abbreviated as USS or U.S.S.) is a ship prefix used to identify a commissioned ship of the United States Navy and applies to a ship only while it is in commission.  Before commissioning, the vessel may be referred to as a "pre-commissioning unit" (PCU), but is officially referred to by name with no prefix.  After decommissioning, it is referred to by name, with no prefix though commonly, people refer to those ships with the prefix Ex-U.S.S. In service but non-commissioned Navy ships go by the prefix USNS, which stands for United States Naval Ship. The Saginaw Valley Naval Ship Museum is dedicated to documenting the history of the United States Navy.  The museum will be permanently housed in the USS "Edson", a retired United States Navy destroyer that has recently been converted to a museum.  The museum is located in Bay City, Michigan, United States.  The man responsible for this destroyer being opened for a museum is Mike Kegley, the president of the Saginaw Valley Naval Ship Museum, who has worked on the project for the last fifteen years.  This destroyer will be the main event for the museum as it has plans to expand into other exhibits in the years to come.  The vice president Richard Janke, the Secretary Mary Kegley, and the treasurer Mark Janke also run the museum.
