IS-3 (tank)
The IS-3 (also known as Object 703) is a Soviet heavy tank developed in late 1944. Its semi-hemispherical cast turret (resembling that of an upturned soup bowl) became the hallmark of post-war Soviet tanks. Its pike nose design would also be mirrored by other tanks of the IS tank family such as the IS-7 and T-10. Produced too late to see combat in World War II, the IS-3 participated in the Berlin Victory Parade of 1945, the Soviet invasion of Hungary, the Six-Day War, Yom Kippur War, and one was used during the early stages of the Russo-Ukrainian War. Design and production While the IS-2 tank proved to be capable of dealing with most German threats, anti-tank teams armed with Panzerfausts, Panzerschrecks, and PaK 40s proved dangerous since the Soviets used the IS-2 to break through areas weakly supported by tanks. The Soviets nonetheless conducted studies on tank losses, with engineers concluding that most of the hits occurred on the turret followed by hits on the front ...

Heavy Tank
A heavy tank is a tank classification produced from World War I to the end of the Cold War. These tanks generally sacrificed mobility and maneuverability for better armour protection and equal or greater firepower than tanks of lighter classes. Role Heavy tanks achieved their greatest, albeit limited, success when fighting lighter tanks and destroying fortifications. Heavy tanks often saw limited combat in their intended roles, instead becoming mobile pillboxes or defensive positions, such as the German Tiger I and Tiger II designs, or the Soviet Kliment Voroshilov tank, KV and IS tank family, IS designs. Design Heavy tanks feature very heavy vehicle armour, armor and weapons relative to lighter tanks. Many heavy tanks shared components with lighter tanks. For example, the US M103 (heavy tank), M103 heavy tank shared many components with the lighter Patton tank, including transmission and engine. As a result, they tend to be either underpowered and comparatively slow, or hav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IS Tank Family
The IS tanks () were a series of heavy tanks developed as a successor to the KV-series by the Soviet Union during World War II. The IS acronym is the anglicized initialism of Joseph Stalin (, '). The heavy tanks were designed as a response to the capture of a German Tiger I in 1943. They were mainly designed as breakthrough tanks, firing a heavy high-explosive shell that was useful against entrenchments and bunkers. The IS-2 went into service in April 1944 and was used as a spearhead by the Red Army in the final stage of the Battle of Berlin. The IS-3 served on the Chinese-Soviet border, the Hungarian Revolution, the Prague Spring and on both sides of the Six-Day War. The series eventually culminated in the T-10 heavy tank. Design and production KV-85/IS-85/IS-1 The KV-85 was a KV-1S with the new turret from the Object 237 (IS-85) still in development, mounting the 85mm D-5T gun. The tank was a result of the USSR's tank design bureau being torn in two, one half f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hull Down
In sailing and warfare, to be hull down means that the upper part of a vessel or vehicle is visible, but the main, lower body ( hull) is not; the term hull up means that all of the body is visible. The terms originated with sailing and naval warfare in which the curvature of the Earth causes an approaching vessel to be first visible "sails up". Beginning in the 20th century, ''hull down'' has also been used in armoured warfare. In modern armoured warfare, hull down is a position taken up by an armoured fighting vehicle (AFV) so that its hull (the main part of the vehicle) is behind a crest or other raised ground, but its turret (or a superstructure or roof-mounted weapon) is exposed. Turret down is the position in which the vehicle's crew can observe forward from roof hatches, but the vehicle is completely hidden (usually a few metres further back from a hull-down position). The belly armour should not be exposed, because it is vulnerable to even modest antitank weapons. Ships ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metric Tons
The tonne ( or ; symbol: t) is a unit of mass equal to 1,000 kilograms. It is a non-SI unit accepted for use with SI. It is also referred to as a metric ton in the United States to distinguish it from the non-metric units of the short ton (United States customary units) and the long ton ( British imperial units). It is equivalent to approximately 2,204.6 pounds, 1.102 short tons, and 0.984 long tons. The official SI unit is the megagram (Mg), a less common way to express the same amount. Symbol and abbreviations The BIPM symbol for the tonne is t, adopted at the same time as the unit in 1879.Table 6 . BIPM. Retrieved on 2011-07-10. Its use is also official for the metric ton in the United States, having been adopted by the United States |
Esox
''Esox'' is a genus of freshwater fish commonly known as pike or pickerel. It is the type genus of the family (biology), family Esocidae. The type species of the genus is ''Esox lucius'', the northern pike. ''Esox'' have a fossil record extending back to the Paleocene. Modern large pike species are native to the Palearctic and Nearctic realms, ranging across Northern America and from Western Europe to Siberia in North Asia. Pike have the elongated, torpedo-like shape typical of predatory fishes, with sharply pointed heads and sharp teeth. Their coloration is typically grey-green with a mottled or spotted appearance with stripes along their backs, providing camouflage among underwater weeds, and each individual pike marking patterns are unique like fingerprints. Pikes can grow to a maximum recorded length of , reaching a maximum recorded weight of 67lb 8oz. Etymology The generic name ''Esox'' (pike fish) derives from the Greek language, Greek ἴσοξ (''ee-soks'', a large f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Josef Kotin
Josef (also Joseph, Jozef, sometimes Zhozef) Yakovlevich Kotin (; 10 March 1908, Pavlohrad – 21 October 1979, Leningrad) was a Soviet armored vehicle design engineer, Head of all three Leningrad armor design bureaux (1937–39), Chief Designer of the Narkomat for Tank Industry (1939-1941), Deputy Narkom for the tank industry of the Soviet Union (1941-1943), Director of the VNII-100 Research Institute at Kirov Plant, Deputy Defense Industry Minister of the Soviet Union 1968–1972. He is best known for leading the design of some of the Kliment Voroshilov tanks, IS tank family, T-10 tank, SU-152 self-propelled heavy howitzer, Kirovets K-700 tractor and many other armored vehicles and heavy machinery.

PaK 40
The 7.5 cm Pak 40 (''7,5 cm Panzerabwehrkanone 40'') was a German 75 millimetre anti-tank gun of the Second World War. The gun was developed in 1939–1941 and entered service in 1942. With 23,303 examples produced, the Pak 40 formed the backbone of German anti-tank guns for the later part of World War II, mostly in towed form, but also on a number of self propelled artillery such as the '' Marder'' series of ''Panzerjäger''. A modified version of the gun designed specifically for vehicle-mounting was the 7.5 cm KwK 40, which differed primarily in using more compact ammunition, thereby allowing more rounds to be carried inside the vehicles. The KwK 40 armed many of the German mid-war tank designs such as the Panzer IV, as well as tank destroyer designs, replacing the Pak 40 in the latter role. The Pak 40 may be referred to as the 7.5 cm L/46, referring to its calibre and the barrel's length in calibres. There were two versions of the KwK 40, which would be referred t ...

Panzerschreck
''Panzerschreck'' ( "tank's dread" or "tank's bane") was the popular name for the ''Raketenpanzerbüchse'' 54 ("Rocket Anti-armor Rifle Model 54", abbreviated to RPzB 54), an 88 mm reusable anti-tank rocket launcher developed by Nazi Germany in World War II. Another earlier, official name was ''Ofenrohr'' ("stove pipe"). The ''Panzerschreck'' was designed as a lightweight infantry anti-tank weapon and was an enlarged copy of the American bazooka. The weapon was shoulder-launched and fired a fin-stabilized rocket with a shaped-charge warhead. It was made in smaller numbers than the '' Panzerfaust'', which was a light, disposable anti-tank weapon that used a system akin to recoilless rifles. History The ''Panzerschreck'' development was initially based on the American "bazooka", captured during the Tunisian campaign, November 1942. The ''Panzerschreck'' was larger and heavier than its American counterpart – the ''Panzerschreck'' had an 88 mm calibre, compared to ...

Panzerfaust
The (, or , plural: ) was a development family of single-shot man-portable anti-tank systems developed by Nazi Germany during World War II. The weapons were the first single-use light anti-tank weapons based on a pre-loaded disposable launch tube, a weapon configuration which is still used today (a contemporary example being the 84mm AT4). The -design consisted of a light recoilless launcher tube outfitted with a single pre-loaded high-explosive anti-tank warhead protruding from the muzzle. It was an inexpensive, easy-to-use anti-tank weapon for the common infantry man, being issued as a single unit of ammunition meant to be operated by a single soldier. Firing was done from under the arm at an upward angle as the effective firing range was barely beyond that of hand grenades ( max). After use the launcher was discarded. Development of the started in 1942. The initial design was dubbed ( "fist-cartridge") and was smaller than the later designs. Later dubbed ("tank-f ...

Berlin Victory Parade Of 1945
The Berlin Victory Parade of 1945 was held by the Allies of World War II on 7 September 1945 in Berlin, the capital of the defeated Germany, shortly after the end of World War II. The four participating countries were the Soviet Union, the United States, the United Kingdom, and France. The parade was proposed by the Soviet Union, following the June Moscow Victory Parade of 1945. July in Berlin also saw a British parade (the 1945 British Berlin Victory Parade). Senior officers present at the parade were Marshal of the Soviet Union Georgy Zhukov from the USSR, General George S. Patton from the United States, General Brian Robertson, from the United Kingdom, and General Marie-Pierre Kœnig from France. General Dwight D.
