High-explosive Anti-tank Warhead
High-explosive anti-tank (HEAT) is the effect of a shaped charge explosive that uses the Munroe effect to penetrate heavy armor. The warhead functions by having an explosive charge collapse a metal liner inside the warhead into a high-velocity explosively formed penetrator (EFP) jet; this is capable of penetrating armor steel to a depth of seven or more times the diameter of the charge (charge diameters, CD). The EFPs jet effect is purely kinetic in nature; the round has no explosive or incendiary effect on the target. Because they rely on the kinetic energy of the EFP jet for their penetration performance, HEAT warheads do not have to be delivered with high velocity, as an armor-piercing round does. Thus they generate less recoil. The performance of HEAT weapons has nothing to do with thermal effects, with HEAT being simply an acronym. History HEAT warheads were developed during World War II, from extensive research and development into shaped charge warheads. Shaped ...

Firing Pin
A firing pin or striker is a part of the firing mechanism of a firearm that impacts the primer in the base of a cartridge and causes it to fire. In firearms terminology, a striker is a particular type of firing pin where a compressed spring acts directly on the firing pin to provide the impact force rather than it being struck by a hammer. The terms may also be used for a component of equipment or a device which has a similar function. Such equipment or devices include: artillery, munitions and pyrotechnics. Firearms The typical firing pin is a thin, simple rod with a hardened, rounded tip that strikes and crushes the primer. The rounded end ensures the primer is indented rather than pierced (to contain propellant gasses). It sits within a hole through the breechblock and is struck by the hammer when the trigger is "pulled". A light firing-pin spring is often used to keep the firing pin rearward. It may be termed a ''firing-pin return spring'', since it returns it t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spigot Mortar
A mortar is usually a simple, lightweight, man-portable, muzzle-loaded weapon, consisting of a smooth-bore (although some models use a rifled barrel) metal tube fixed to a base plate (to spread out the recoil) with a lightweight bipod mount and a sight. They launch explosive shells (technically called bombs) in high-arcing ballistic trajectories. Mortars are typically used as indirect fire weapons for close fire support with a variety of ammunition. History Mortars have been used for hundreds of years. The earliest mortars were used in Korea in a 1413 naval battle when Korean gunsmiths developed the ''wan'gu'' (gourd-shaped mortar) (완구, 碗口). The earliest version of the ''wan'gu'' dates back to 1407. Choi Hae-san (최해산, 崔海山) (1380–1443), the son of Choe Mu-seon (최무선, 崔茂宣) (1325–1395), is generally credited with inventing the ''wan'gu''. In the Ming dynasty, general Qi Jiguang recorded the use of a mini cannon called the Hu dun pao that wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Millis Jefferis
Major-General Sir Millis Rowland Jefferis KBE MC (9 January 1899 – 5 September 1963) was a British military officer who founded a special unit of the British Ministry of Supply which developed unusual weapons during the Second World War. Early career Born at Merstham, Surrey on 9 January 1899, Jefferis was educated at Tonbridge School and Royal Military Academy, Woolwich. From Woolwich he was commissioned into the Royal Engineers on 6 June 1918, during the final months of World War I, and after passing through the School of Military Engineering at Chatham, he was posted to the First Field Squadron RE in the British Army of the Rhine (BAOR).''Sir Millis Jefferis New Weapons of War (Obituary)''. ''The Times'', 7 September 1963 p10 column E. In 1920 he went to India and served with the Queen's Own Madras Sappers and Miners in the Third Field Troop at Sialkot. In 1922 he went into the Works Services in India as garrison engineer at Kohat and then at Khaisora which is today ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battleship
A battleship is a large armour, armored warship with a main artillery battery, battery consisting of large caliber guns. It dominated naval warfare in the late 19th and early 20th centuries. The term ''battleship'' came into use in the late 1880s to describe a type of ironclad warship,Stoll, J. ''Steaming in the Dark?'', Journal of Conflict Resolution Vol. 36 No. 2, June 1992. now referred to by historians as pre-dreadnought battleships. In 1906, the commissioning of into the United Kingdom's Royal Navy heralded a revolution in the field of battleship design. Subsequent battleship designs, influenced by HMS ''Dreadnought'', were referred to as "dreadnoughts", though the term eventually became obsolete as dreadnoughts became the only type of battleship in common use. Battleships were a symbol of naval dominance and national might, and for decades the battleship was a major factor in both diplomacy and military strategy.Sondhaus, L. ''Naval Warfare 1815–1914'', .

Mistel
''Mistel'' (German for " mistletoe", a parasitic plant) was the larger, unmanned component of a composite aircraft configuration developed in Germany during the later stages of World War II. The composite comprised a small piloted control aircraft mounted above a large explosives-carrying drone, the Mistel, and as a whole was referred to as the ''Huckepack'' ("Piggyback"), also known as the ''Beethoven-Gerät'' ("Beethoven Device") or ''Vati und Sohn'' ("Daddy and Son"). The most successful of these used a modified Junkers Ju 88 bomber as the ''Mistel'', with the entire nose-located crew compartment replaced by a specially designed nose filled with a large load of explosives, formed into a shaped charge. The upper component was a fighter aircraft, joined to the Mistel by struts. The combination would be flown to its target by a pilot in the fighter; then the unmanned bomber was released to hit its target and explode, leaving the fighter free to return to base. The first such ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PIAT
The Projector, Infantry, Anti Tank (PIAT) Mk I was a British man-portable anti-tank weapon developed during the Second World War. The PIAT was designed in 1942 in response to the British Army's need for a more effective infantry anti-tank weapon and entered service in 1943. The PIAT was based on the spigot mortar system, and projected (launched) a 2.5 pound (1.1 kg) shaped charge bomb using a cartridge in the tail of the projectile. It possessed an effective range of approximately in a direct fire anti-tank role, and in an indirect fire role. The PIAT had several advantages over other infantry anti-tank weapons of the period: it had greatly increased penetration power over the previous anti-tank rifles, it had no back-blast which might reveal the position of the user or accidentally injure friendly soldiers around the user, and it was simple in construction. However, the device also had some disadvantages: powerful recoil, a difficulty in cocking the weapon, and early prob ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bundesarchiv Bild 101I-671-7483-29, Reichsgebiet, Soldat Mit Panzerabwehrwaffe
The German Federal Archives or Bundesarchiv (BArch) (german: Bundesarchiv) are the National Archives of Germany. They were established at the current location in Koblenz in 1952. They are subordinated to the Federal Commissioner for Culture and the Media (Claudia Roth since 2021) under the German Chancellery, and before 1998, to the Federal Ministry of the Interior (Germany), Federal Ministry of the Interior. On 6 December 2008, the Archives donated 100,000 photos to the public, by making them accessible via Wikimedia Commons. History The federal archive for institutions and authorities in Germany, the first precursor to the present-day Federal Archives, was established in Potsdam, Brandenburg in 1919, a later date than in other European countries. This national archive documented German government dating from the founding of the North German Confederation in 1867. It also included material from the older German Confederation and the Imperial Chamber Court. The oldest documents i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Panzerfaust
The ''Panzerfaust'' (, "armour fist" or "tank fist", plural: ''Panzerfäuste'') 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 (two modern examples being the AT4 and NLAW). The ''Panzerfaust''-design consisted of a light recoilless launcher tube outfitted with a single pre-loaded high-explosive anti-tank warhead protruding from the muzzle, much like a "fist", hence the name. 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 disposed of, much like the safety pin in hand grenades. D ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Panzerschreck
''Panzerschreck'' (lit. "tank fright", "tank's fright" 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 not unlike those of 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paratrooper
A paratrooper is a military parachutist—someone trained to parachute into a military operation, and usually functioning as part of an airborne force. Military parachutists (troops) and parachutes were first used on a large scale during World War II for troop distribution and transportation. Paratroopers are often used in surprise attacks, to seize strategic objectives such as airfields or bridges. Overview Paratroopers jump out of airplanes and use parachutes to land safely on the ground. This is one of the three types of "forced entry" strategic techniques for entering a theater of war; the other two being by land and by water. Their tactical advantage of entering the battlefield from the air is that they can attack areas not directly accessible by other transport. The ability of air assault to enter the battlefield from any location allows paratroopers to evade emplaced fortifications that guard from attack from a specific direction. The possible use of paratroopers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
