The FuMO 21 (Funkmess-Ortung, "Radio-direction finder, active ranging") was designed in 1941 as a search radar for Nazi Germany's Kriegsmarine , suitable for ships between light cruiser and large torpedo boats in size. First designated FMG [Note 1] 39G(gL), [1] it received its final designation when the Kriegsmarine revised its radar nomenclature system around 1943. [2] It was derived from the earlier Seetakt search radar and had an antenna 2 m × 4 m (6 ft 7 in × 13 ft 1 in) in size. [1]
Seetakt was a shipborne radar developed in the 1930s and used by Nazi Germany's Kriegsmarine during World War II.
The Type 1934A destroyers, also known as the Z5 class, were a group of twelve destroyers built in the mid-1930s for Nazi Germany's Kriegsmarine. Five survived the war.
The German torpedo boat T25 was one of fifteen Type 39 torpedo boats built for the Kriegsmarine during World War II. Completed in late 1942, she was transferred to France in July 1943. T25 was unsuccessfully attacked by Allied motor torpedo boats and aircraft during her voyage down the English Channel and then came to the aid of a convoy being attacked by Allied destroyers. Later that year she escorted blockade runners and Axis submarines through the Bay of Biscay. T25 also helped to lay minefields in the English Channel in mid-1943. She participated in the Battle of Sept-Îles in October and was sunk two months later by British light cruisers during the Battle of the Bay of Biscay.
The German torpedo boat T26 was one of fifteen Type 39 torpedo boats built for the Kriegsmarine during World War II. Completed in early 1943, the boat was transferred to France in August. T26 helped to lay a minefield in the English Channel the following month, and later escorted a blockade runner through the Bay of Biscay. She participated in the Battle of Sept-Îles in October and was sunk two months later by a British light cruiser during the Battle of the Bay of Biscay.
The German torpedo boat T36 was the last of 15 Type 39 torpedo boats built for the Kriegsmarine during World War II. Completed in late 1944, T36 was assigned to convoy escort duties and supporting German forces in the Baltic. At the end of January 1945, she rescued survivors from the torpedoed ocean liner MV Wilhelm Gustloff. The boat screened German warships as they bombarded advancing Soviet troops and escorted convoys over the next several months. In May, T36 began to ferry refugees; she struck a mine on 4 May and was sunk by Soviet aircraft the following day.
The German torpedo boat T6 was one of a dozen Type 35 torpedo boats built for the Kriegsmarine during the late 1930s. Completed in 1940, she initially escorted ships through the Skaggerak before she was assigned to escort minelayers as they laid their minefields in the North Sea and English Channel in July. T6 started laying her own minefields two months later and was flagship of the 2nd Torpedo Boat Flotilla when she struck a mine and sank when attempting to attack several convoys off the Scottish coast in November.
The Type 1939 torpedo boats, also known as the Elbing class by the Allies, were a group of 15 torpedo boats that were built for Nazi Germany's Kriegsmarine during World War II.
The German torpedo boat T35 was one of fifteen Type 39 torpedo boats built for the Kriegsmarine during World War II. Completed in late 1944, she was assigned to convoy escort duties and supporting German forces in the Baltic. The ship escorted a heavy cruiser in January 1945 as she bombarded Soviet troops and helped to evacuate troops and refugees from advancing Soviet forces in May. T35 was allocated to the United States after the war, but was turned over to the French Navy in 1947 to be used as a source of spare parts. She was stricken from the Navy List in 1952 and subsequently sold for scrap.
The German torpedo boat T34 was one of fifteen Type 39 torpedo boats built for the Kriegsmarine during World War II. Completed in mid-1944, the boat was still working up in the Baltic when she struck a mine in November and sank.
The German torpedo boat T33 was one of fifteen Type 39 torpedo boats built for the Kriegsmarine during World War II. Completed in mid-1944, the boat was assigned to convoy escort duties and supporting German forces in the Baltic. She escorted a heavy cruiser in January 1945 as she bombarded Soviet troops and helped to evacuate troops and refugees from advancing Soviet forces in May. T33 was allocated to the Soviet Union after the war and was renamed Primerny. She served with the Baltic Fleet until 1954 when the ship was converted into an accommodation ship and renamed PKZ-63. She was turned over to be scrapped on 9 November 1956 and subsequently broken up.
The German torpedo boat T32 was one of fifteen Type 39 torpedo boats built for the Kriegsmarine during World War II. Completed in mid-1944, the boat was assigned to convoy escort duties and supporting German forces in the Baltic. On 18 August 1944, a navigational error led her to enter a German minefield as she was preparing to lay another minefield in the Gulf of Finland off the Estonian coast. T32 struck two mines that crippled her. She was sunk by Soviet aircraft with the loss of 137 crewmen later that morning.
The German torpedo boat T31 was one of fifteen Type 39 torpedo boats built for the Kriegsmarine during World War II. Completed in early 1944, the boat was assigned to convoy escort duties and supporting German forces in the Baltic. She was sunk in combat with Soviet motor torpedo boats on 20 June off the Finnish coast on 20 June with 82 men killed.
The German torpedo boat T30 was one of fifteen Type 39 torpedo boats built for the Kriegsmarine during World War II. Completed in late 1943, the boat was assigned to support German operations in the Baltic Sea. She laid minefields in the Gulf of Finland, off the Estonian coast, in mid-April, before she was tasked to support Finnish forces in June. The following month, T30 helped to sink a Soviet patrol boat. After a navigational error caused her to enter a German minefield as she was preparing to lay one herself in August, the boat sank after striking several mines with the loss of 137 crewmen.
The German torpedo boat T29 was one of fifteen Type 39 torpedo boats built for the Kriegsmarine during World War II. Completed in mid-1943, the boat was transferred to France in January 1944. She fought in the Action of 26 April off the coast of Brittany, and was sunk by four Allied destroyers with the loss of 137 crewmen.
The German torpedo boat T28 was one of fifteen Type 39 torpedo boats built for the Kriegsmarine during World War II. Completed in mid-1943, the ship was transferred to France in January 1944 and slightly damaged by British aircraft en route. She attacked Allied ships during the Invasion of Normandy in June 1944 and returned to Germany the following month. T28 was assigned to support German operations in the Baltic Sea. She escorted convoys and larger warships bombarding Soviet troops as well as bombarding them herself. In May T28 helped to evacuate troops and refugees from advancing Soviet forces. The ship was allocated to Great Britain after the war, but she was transferred to France in 1946. The French Navy renamed her Le Lorrain and recommissioned her in 1949. After serving with different units of the Mediterranean Squadron, she was condemned in 1955 and subsequently sold for scrap.
The German torpedo boat T27 was one of fifteen Type 39 torpedo boats built for the Kriegsmarine during World War II. Completed in early 1943, the boat was transferred to France in August. T27 helped to lay a minefield in the English Channel the following month, and later escorted a blockade runner through the Bay of Biscay. She participated in the Battle of Sept-Îles in October and played a minor role in the Battle of the Bay of Biscay. The boat was lightly damaged during the action of 26 April 1944 off the coast of Brittany and ran aground during the subsequent battle two days later. Her wreck was destroyed shortly afterwards by the British.
The German torpedo boat T22 was one of fifteen Type 39 torpedo boats built for the Kriegsmarine during World War II. Completed in early 1942, the ship was transferred to France later that year where she escorted blockade runners and Axis submarines through the Bay of Biscay. T22 also laid minefields in the English Channel in mid-1943. She participated in the Battle of Sept-Îles, where she crippled a British destroyer, and the Battle of the Bay of Biscay later that year. After returning to Germany in early 1944, T22 struck a pair of mines in Narva Bay in August and blew up, with the loss of 143 men.
The Type 1941 torpedo boats were a group of 15 torpedo boats that were built for Nazi Germany's Kriegsmarine during World War II. Ordered in late 1942, none of the ships were finished before the German surrender on 8/9 May 1945, although four of the ships had been towed west to be completed earlier in that year. They were all either scuttled or demolished in the shipyard in 1945–1946.
The FuMO 24 and 25 were designed as a replacement for the earlier FuMO search radar for Nazi Germany's Kriegsmarine in 1943. The differences between the two models are not clear and it usually used a larger 2-by-6-meter antenna than the older system.
The Ersatz (Replacement) Triglav class consisted of four destroyers built for the Austro-Hungarian Navy during the First World War. Completed late in the war, they saw little action; three ships were seized by Italy and one by France as war reparations in 1920.
