HMS Activity
HMS ''Activity'' was an escort carrier that served with the Royal Navy of the United Kingdom during the Second World War. After the war, she was sold into merchant service as the MV ''Breconshire'', serving for over 20 years until scrapped in 1967. History Royal Navy HMS ''Activity'' was built at Caledon shipyards in Dundee. When construction started in 1940 she was intended to become the refrigerated cargo ship ''Telemachus'' for the Alfred Holt Line. In February 1941, she was taken over by the Ministry of War Transport and renamed ''Empire Activity''. In January 1942, she was requisitioned by the Admiralty for conversion to an escort carrier, now named HMS ''Activity'' and carrying pennant number D94. Following her launch in May 1942 and completion in August of that year, ''Activity'' worked up at Lamlash before going to Rosyth for rectification of defects. Entering service on 1 January 1943, ''Activity'' operated as a deck landing training carrier until October 1943, wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Luftwaffe
The ''Luftwaffe'' () was the aerial-warfare branch of the German '' Wehrmacht'' before and during World War II. Germany's military air arms during World War I, the '' Luftstreitkräfte'' of the Imperial Army and the '' Marine-Fliegerabteilung'' of the Imperial Navy, had been disbanded in May 1920 in accordance with the terms of the 1919 Treaty of Versailles which banned Germany from having any air force. During the interwar period, German pilots were trained secretly in violation of the treaty at Lipetsk Air Base in the Soviet Union. With the rise of the Nazi Party and the repudiation of the Versailles Treaty, the ''Luftwaffe''s existence was publicly acknowledged on 26 February 1935, just over two weeks before open defiance of the Versailles Treaty through German rearmament and conscription would be announced on 16 March. The Condor Legion, a ''Luftwaffe'' detachment sent to aid Nationalist forces in the Spanish Civil War, provided the force with a valuable testin ...

Grumman TBF Avenger
The Grumman TBF Avenger (designated TBM for aircraft manufactured by General Motors) is an American World War II-era torpedo bomber developed initially for the United States Navy and Marine Corps, and eventually used by several air and naval aviation services around the world. The Avenger entered U.S. service in 1942, and first saw action during the Battle of Midway. Despite the loss of five of the six Avengers on its combat debut, it survived in service to become the most effective and widely-used torpedo bomber of World War II, sharing credit for sinking the super-battleships and (the only ships of that type sunk exclusively by American aircraft while under way) and being credited for sinking 30 submarines. Greatly modified after the war, it remained in use until the 1960s.Wheeler 1992, p. 53. Design and development The Douglas TBD Devastator, the U.S. Navy's main torpedo bomber introduced in 1935, was obsolescent by 1939. Bids were accepted from several companies, but Gru ...

Grumman Martlet
The Grumman F4F Wildcat is an American carrier-based fighter aircraft that entered service in 1940 with the United States Navy, and the British Royal Navy where it was initially known as the Martlet. First used by the British in the North Atlantic, the Wildcat was the only effective fighter available to the United States Navy and Marine Corps in the Pacific Theater during the early part of the Second World War. The disappointing Brewster Buffalo was withdrawn in favor of the Wildcat and replaced as aircraft became available. With a top speed of , the Wildcat was outperformed by the faster (), more maneuverable, and longer-ranged Mitsubishi A6M Zero. US Navy pilots, including John "Jimmy" Thach, a pioneer of fighter tactics to deal with the A6M Zero, were greatly dissatisfied with the Wildcat's inferior performance against the Zero in the battles of the Coral Sea and Midway. The Wildcat has a claimed air combat kill-to-loss ratio of 5.9:1 in 1942 and 6.9:1 for the entire war.Pol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fairey Swordfish
The Fairey Swordfish is a biplane torpedo bomber, designed by the Fairey Aviation Company. Originating in the early 1930s, the Swordfish, nicknamed "Stringbag", was principally operated by the Fleet Air Arm of the Royal Navy. It was also used by the Royal Air Force (RAF), as well as several overseas operators, including the Royal Canadian Air Force (RCAF) and the Royal Netherlands Navy. It was initially operated primarily as a fleet attack aircraft. During its later years, the Swordfish was increasingly used as an anti-submarine and training platform. The type was in frontline service throughout the Second World War. Despite being outmoded by 1939, the Swordfish achieved some spectacular successes during the war. Notable events included sinking one battleship and damaging two others of the ''Regia Marina'' (the Italian navy) during the Battle of Taranto, and the famous attack on the German battleship ''Bismarck'', which contributed to her eventual demise. Swordfish sank a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hedgehog (weapon)
The Hedgehog (also known as an ''Anti-Submarine Projector'') was a forward-throwing anti-submarine weapon that was used primarily during the Second World War. The device, which was developed by the Royal Navy, fired up to 24 spigot mortars ahead of a ship when attacking a U-boat. It was deployed on convoy escort warships such as destroyers and corvettes to supplement the depth charges. As the mortar projectiles employed contact fuzes rather than time or barometric (depth) fuzes, detonation occurred directly against a hard surface such as the hull of a submarine making it more deadly than depth charges, which relied on damage caused by hydrostatic shockwaves. During WWII out of 5,174 British depth charge attacks there were 85.5 kills, a ratio of 60.5 to 1. In comparison, the Hedgehog made 268 attacks for 47 kills, a ratio of 5.7 to 1. Development The "Hedgehog", so named because the empty rows of its launcher spigots resembled the spines on the back of a hedgehog, was a repl ...

Norwegian Sea
The Norwegian Sea ( no, Norskehavet; is, Noregshaf; fo, Norskahavið) is a marginal sea, grouped with either the Atlantic Ocean or the Arctic Ocean, northwest of Norway between the North Sea and the Greenland Sea, adjoining the Barents Sea to the northeast. In the southwest, it is separated from the Atlantic Ocean by a submarine ridge running between Iceland and the Faroe Islands. To the north, the Jan Mayen Ridge separates it from the Greenland Sea. Unlike many other seas, most of the bottom of the Norwegian Sea is not part of a continental shelf and therefore lies at a great depth of about two kilometres on average. Rich deposits of oil and natural gas are found under the sea bottom and are being explored commercially, in the areas with sea depths of up to about one kilometre. The coastal zones are rich in fish that visit the Norwegian Sea from the North Atlantic or from the Barents Sea (cod) for spawning. The warm North Atlantic Current ensures relatively stable and high wate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
