Convoy ON 144
Convoy ON 144 was a trade convoy of merchant ships during the Second World War. It was the 144th of the numbered series of ON convoys Outbound from the British Isles to North America. The ships departed Liverpool on 7 November 1942 and were joined on 8 November Hague pp.158&161 by Mid-Ocean Escort Force Group B-6 consisting of the s , , , and and the convoy rescue ship ''Perth''.Milner pp.180-181 Group B-6 had sailed without the destroyers and which had been damaged in the battle for eastbound convoy SC 104. The United States Coast Guard cutters ''Bibb'', ''Duane'', and ''Ingham'' accompanied the convoy from the Western Approaches with ships that detached for Iceland on 15 November. Background As western Atlantic coastal convoys brought an end to the second happy time, Admiral Karl Dönitz, the '' Befehlshaber der U-Boote'' (''BdU'') or commander in chief of U-Boats, shifted focus to the mid-Atlantic to avoid aircraft patrols. Although convoy routing was less predictabl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battle Of The Atlantic
The Battle of the Atlantic, the longest continuous military campaign in World War II, ran from 1939 to the defeat of Nazi Germany in 1945, covering a major part of the naval history of World War II. At its core was the Allied naval blockade of Germany, announced the day after the declaration of war, and Germany's subsequent counter-blockade. The campaign peaked from mid-1940 through to the end of 1943. The Battle of the Atlantic pitted U-boats and other warships of the German '' Kriegsmarine'' (Navy) and aircraft of the ''Luftwaffe'' (Air Force) against the Royal Navy, Royal Canadian Navy, United States Navy, and Allied merchant shipping. Convoys, coming mainly from North America and predominantly going to the United Kingdom and the Soviet Union, were protected for the most part by the British and Canadian navies and air forces. These forces were aided by ships and aircraft of the United States beginning September 13, 1941. Carney, Robert B., Admiral, USN. "Comment and D ...

Convoy Rescue Ship
A convoy is a group of vehicles, typically motor vehicles or ships, traveling together for mutual support and protection. Often, a convoy is organized with armed defensive support and can help maintain cohesion within a unit. It may also be used in a non-military sense, for example when driving through remote areas. Naval convoys Age of Sail Naval convoys have been in use for centuries, with examples of merchant ships traveling under naval protection dating to the 12th century. The use of organized naval convoys dates from when ships began to be separated into specialist classes and national navies were established. By the French Revolutionary Wars of the late 18th century, effective naval convoy tactics had been developed to ward off pirates and privateers. Some convoys contained several hundred merchant ships. The most enduring system of convoys were the Spanish treasure fleets, that sailed from the 1520s until 1790. When merchant ships sailed independently, a privateer could ...

Type 271 Radar
The Type 271 was a surface search radar used by the Royal Navy and allies during World War II. The first widely used naval microwave-frequency system, it was equipped with an antenna small enough to allow it to be mounted on small ships like corvettes and frigates, while its improved resolution over earlier radars allowed it to pick up a surfaced U-boat at around and its periscope alone at . The prototype, 271X, was fitted to HMS ''Orchis'' in March 1941 and declared operational in May. Small numbers became available during the year, with about thirty sets in operation by October. The design spawned two larger versions, Type 272 for destroyers and small cruisers, and Type 273 for larger cruisers and battleships. The 272 was not considered successful and not widely used. The 273 differed in having larger and more focused antennas, providing higher gain and thus longer range. This proved very successful and was widely used. Improved versions, known alternately as Q models ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
B-Dienst
The ''B-Dienst'' (german: Beobachtungsdienst, observation service), also called x''B-Dienst'', X-''B-Dienst'' and χ''B-Dienst'', was a Department of the German Naval Intelligence Service (german: Marinenachrichtendienst, MND III) of the OKM, that dealt with the interception and recording, decoding and analysis of the enemy, in particular British radio communications before and during World War II. B-Dienst worked on cryptanalysis and deciphering (decrypting) of enemy and neutral states' message traffic and security control of ''Kriegsmarine'' key processes and machinery. :"The ultimate goal of all evaluation was recognizing the opponent's goal by pro-active identification of data." B-Dienst was instrumental in moulding Wehrmacht operations during the Battles of Norway and France in spring 1940, primarily due to the cryptanalysis successes it had achieved against early and less secure British Naval cyphers. B-Dienst broke British Naval Combined Cypher No. 3 in October 1941, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Befehlshaber Der U-Boote
The ''Befehlshaber der Unterseeboote'' or BdU (Eng: "Commander of the U-boats") was the supreme commander of the German Navy's U-boat Arm (''Ubootwaffe'') during the First and Second World Wars. The term also referred to the Command HQ of the U-boat arm. The title was established in June 1917, replacing the role of "Leader of the U-boats" (''Führer der Unterseeboote,'' or FdU) for the High Seas Flotillas. The first incumbent was ''Kapitan zur See/Kommodore'' Andreas Michelsen, previously head of the High Seas Fleet’s destroyer force. The post was abolished with the end of the war. It was revived on 17 October 1939, when Karl Dönitz was promoted to rear admiral (''Konteradmiral''). His previous title had been FdU, a position he had held from January 1936. On 31 January 1943 Dönitz was promoted to grand admiral (''Großadmiral'') and became supreme commander (''Oberbefehlshaber der Kriegsmarine'') of the entire Kriegsmarine, replacing Erich Raeder Erich Johann Albert R ...

Second Happy Time
The "Second Happy Time" (; officially Operation Paukenschlag ("Operation Drumbeat"), and also known among German submarine commanders as the "American Shooting Season") was a phase in the Battle of the Atlantic during which Axis submarines attacked merchant shipping and Allied naval vessels along the east coast of North America. The first "Happy Time" was in 1940–1941 in the North Atlantic and North Sea. Adolf Hitler and Benito Mussolini declared war on the United States on 11 December 1941, and as a result their navies could begin the "Second Happy Time". The "Second Happy Time" lasted from January 1942 to about August of that year and involved several German naval operations, including Operation Neuland. German submariners named it the "Happy Time" or the "Golden Time," as defense measures were weak and disorganized, and the U-boats were able to inflict massive damage with little risk. During this period, Axis submarines sank 609 ships totaling 3.1 million tons. This l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iceland
Iceland ( is, Ísland; ) is a Nordic island country in the North Atlantic Ocean and in the Arctic Ocean. Iceland is the most sparsely populated country in Europe. Iceland's capital and largest city is Reykjavík, which (along with its surrounding areas) is home to over 65% of the population. Iceland is the biggest part of the Mid-Atlantic Ridge that rises above sea level, and its central volcanic plateau is erupting almost constantly. The interior consists of a plateau characterised by sand and lava fields, mountains, and glaciers, and many glacial rivers flow to the sea through the lowlands. Iceland is warmed by the Gulf Stream and has a temperate climate, despite a high latitude just outside the Arctic Circle. Its high latitude and marine influence keep summers chilly, and most of its islands have a polar climate. According to the ancient manuscript , the settlement of Iceland began in 874 AD when the Norwegian chieftain Ingólfr Arnarson became the first ...

Western Approaches
The Western Approaches is an approximately rectangular area of the Atlantic Ocean lying immediately to the west of Ireland and parts of Great Britain. Its north and south boundaries are defined by the corresponding extremities of Britain. The coast of the mainland forms the eastern side and the western boundary is the 30 degree meridian, which passes through Iceland. The area is particularly important to the United Kingdom, because many of its larger shipping ports lie within it. The term is most commonly used when discussing naval warfare, notably during the First World War and Battle of the Atlantic during the Second World War in which Nazi Germany's ''Kriegsmarine'' attempted to blockade the United Kingdom using submarines (U-boats) operating in this area. Since almost all shipping to and from the United Kingdom passed through this area, it was an excellent hunting ground and had to be heavily defended.

United States Coast Guard Cutter
United States Coast Guard Cutter is the term used by the U.S. Coast Guard for its commissioned vessels. They are or greater in length and have a permanently assigned crew with accommodations aboard. They carry the ship prefix USCGC. History of the USCG cutters The Revenue Marine and the Revenue Cutter Service, as it was known variously throughout the late 18th and the 19th centuries, referred to its ships as cutters. The term is English in origin and refers to a specific type of vessel, namely, "a small, decked ship with one mast and bowsprit, with a gaff mainsail on a boom, a square yard and topsail, and two jibs or a jib and a staysail." With general usage, that term came to define any vessel of the United Kingdom's HM Customs and Excise and the term was adopted by the U.S. Treasury Department at the creation of what would become the Revenue Marine. Since that time, no matter what the vessel type, the service has referred to its vessels with permanently assign ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
