37mm Gun M1
The 37 mm gun M1 was an anti-aircraft autocannon developed in the United States. It was used by the US Army in World War II. The gun was produced in a towed variant, or mounted along with two M2 machine guns on the M2/ M3 half-track, resulting in the T28/T28E1/M15/M15A1 series of multiple gun motor carriages. In early World War II, each Army Anti-Aircraft Artillery (AAA) Auto-Weapons battalion was authorized a total of thirty-two 37 mm guns in its four firing batteries, plus other weapons. During World War II the 37 mm gun M1 was deployed in coast defense anti- motor torpedo boat batteries (AMTB) alongside 90 mm guns, usually four 90 mm and two 37 mm guns per battery. Some AMTB batteries consisted of four 37 mm guns, but most sources have little information on these batteries. In the later part of the war the 37 mm gun was typically replaced by the 40 mm Bofors gun M1.McGovern and Smith, p. 43 Components Two gun units were coupled to the ...

Solomon Islands
Solomon Islands is an island country consisting of six major islands and over 900 smaller islands in Oceania, to the east of Papua New Guinea and north-west of Vanuatu. It has a land area of , and a population of approx. 700,000. Its capital, Honiara, is located on the largest island, Guadalcanal. The country takes its name from the wider area of the Solomon Islands (archipelago), which is a collection of Melanesian islands that also includes the Autonomous Region of Bougainville (currently a part of Papua New Guinea), but excludes the Santa Cruz Islands. The islands have been settled since at least some time between 30,000 and 28,800 BCE, with later waves of migrants, notably the Lapita people, mixing and producing the modern indigenous Solomon Islanders population. In 1568, the Spanish navigator Álvaro de Mendaña was the first European to visit them. Though not named by Mendaña, it is believed that the islands were called ''"the Solomons"'' by those who later receiv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ammunition
Ammunition (informally ammo) is the material fired, scattered, dropped, or detonated from any weapon or weapon system. Ammunition is both expendable weapons (e.g., bombs, missiles, grenades, land mines) and the component parts of other weapons that create the effect on a target (e.g., bullets and warheads). The purpose of ammunition is to project a force against a selected target to have an effect (usually, but not always, lethal). An example of ammunition is the firearm cartridge, which includes all components required to deliver the weapon effect in a single package. Until the 20th century, black powder was the most common propellant used but has now been replaced in nearly all cases by modern compounds. Ammunition comes in a great range of sizes and types and is often designed to work only in specific weapons systems. However, there are internationally recognized standards for certain ammunition types (e.g., 5.56×45mm NATO) that enable their use across different weapo ...

Anti-aircraft Guns Of The United States
Anti-aircraft warfare, counter-air or air defence forces is the battlespace response to aerial warfare, defined by NATO as "all measures designed to nullify or reduce the effectiveness of hostile air action".AAP-6 It includes Surface-to-air missile, surface based, subsurface (Submarine#Armament, submarine launched), and air-based weapon systems, associated sensor systems, command and control arrangements, and passive measures (e.g. barrage balloons). It may be used to protect naval, ground, and air forces in any location. However, for most countries, the main effort has tended to be homeland defence. NATO refers to airborne air defence as counter-air and naval air defence as anti-aircraft warfare. Missile defense, Missile defence is an extension of air defence, as are initiatives to adapt air defence to the task of intercepting any projectile in flight. In some countries, such as Britain and Germany during the World War II, Second World War, the Soviet Union, and modern NATO a ...

Kerrison Predictor
The Kerrison Predictor was one of the first fully automated anti-aircraft fire-control systems. It was used to automate the aiming of the British Army's Bofors 40 mm guns and provide accurate lead calculations through simple inputs on three main handwheels. The predictor could aim a gun at an aircraft based on simple inputs like the observed speed and the angle to the target. Such devices had been used on ships for gunnery control for some time, and versions such as the Vickers Predictor were available for larger anti-aircraft guns intended to be used against high-altitude bombers. Kerrison's analog computer was the first to be fast enough to be used in the demanding high-speed low-altitude role, which involved very short engagement times and high angular rates. The design was also adopted for use in the United States, where it was produced by Singer Corporation as the M5 Antiaircraft Director, later updated as the M5A1 and M5A2. The M6 was mechanically identical, differing only ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

QF 2-pounder Naval Gun
The 2-pounder gun, officially the QF 2-pounder ( QF denoting "quick firing") and universally known as the pom-pom, was a British autocannon, used as an anti-aircraft gun by the Royal Navy.British military of the period traditionally denoted smaller guns in terms of the approximate weight of the standard projectile, rather than by its bore diameter, which in this case was 40 mm. References to 40-mm anti-aircraft guns invariably mean the Bofors gun, while references to 2-pounder anti-aircraft guns mean this gun. The name came from the sound that the original models make when firing. This QF 2-pounder was not the same gun as the Ordnance QF 2-pounder, used by the British Army as an anti-tank gun and a tank gun, although they both fired , projectiles. Predecessors - Boer War and the Great War QF 1 pounder The first gun to be called a pom-pom was the 37 mm Nordenfelt-Maxim or "QF 1-pounder" introduced during the Second Boer War, the smallest artillery piece of that war.

37 Mm Automatic Air Defense Gun M1939 (61-K)
The 37 mm automatic air defense gun M1939 (61-K) (russian: 37-мм автоматическая зенитная пушка образца 1939 года (61-К)) is a Soviet 37 mm calibre anti-aircraft gun developed during the late 1930s and used during World War II. The land-based version was replaced in Soviet service by the AZP S-60 during the 1950s. Guns of this type were successfully used throughout the Eastern Front against dive bombers and other low- and medium-altitude targets. It also had some usefulness against lightly armoured ground targets. Development The Soviet Navy purchased a number of Bofors 25 mm Model 1933 guns in 1935, trials of the weapon were successful and it was decided to develop a 45 mm version of the weapon designated the 49-K. The development under the guidance of leading Soviet designers M. N. Loginov, I. A. Lyamin and L. V. Lyuliev was successful, but the army thought that the 45 mm calibre was a little too large for a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cannone-Mitragliera Da 37/54 (Breda)
The Cannone-Mitragliera da 37/54 (Breda) was a automatic anti-aircraft gun produced by the Breda company in Italy. It was used by both the Regia Marina and the Regio Esercito during World War II, with the former using it as the standard light anti-aircraft weapon on its battleships and cruisers. Nazi Germany used captured weapons after the surrender of Italy The Armistice of Cassibile was an armistice signed on 3 September 1943 and made public on 8 September between the Kingdom of Italy and the Allies during World War II. It was signed by Major General Walter Bedell Smith for the Allies and Brigad ... in 1943 as the ''3.7 cm Breda (i)''. Design The Model 1932 was water-cooled while Models 1938 and 1939 were air-cooled. The gun was fed by a flat magazine holding six rounds which could be loaded one after another to maintain a high rate of fire. It was possible to select alternate rates of fire, either 60, 90 or 120 rpm. The twin mountings for Models 1932 and 1938 were very ...

Canon De 37 Mm Modèle 1925
The Canon de 37 mm Modèle 1925 was a widely used family of French anti-aircraft guns used by the French Navy during World War II. Design & Construction The Modèle 1925 was a single gun mount while the later Modèle 1933 was a twin mount. Both were hand-loaded, semi-automatic guns with a low rate of fire compared to their clip-fed contemporaries. A combination of low rate of fire, low projectile weight and small numbers of guns per ship led to a reputation of it being a poor anti-aircraft weapon. Ship classes that carried Modèle 1925 & Modèle 1933 include: *Aigle-class destroyers *Bougainville-class avisos *Bourrasque-class destroyers *Chacal-class destroyers *Dunkerque-class battleships * Duquesne-class cruisers *Guépard-class destroyers *L'Adroit-class destroyers *La Melpomène-class torpedo boats *Le Fantasque-class destroyers * Le Fier-class torpedo boats *Mogador-class destroyers *Richelieu-class battleships * Suffren-class cruisers * Vauquelin-class destroyers ...

M4 Cannon
The 37 mm Automatic Gun, M4, known as the T9 during development, was a 37 mm (1.46 in) recoil-operated autocannon designed by Browning Arms Company. The weapon, which was built by Colt, entered service in 1942. It was primarily mounted in the Bell P-39 Airacobra and P-63 Kingcobra, with the U.S. Navy also utilizing it on many PT boats. Design Designed primarily as an anti-aircraft weapon, the gun had a muzzle velocity of and a cyclic rate of 150 rounds per minute. It was normally loaded with high-explosive shells, but could also be loaded with the M80 armor-piercing shell, which could penetrate 1 inch (25 mm) of armor plate at . It was magazine-fed and could be fired manually or by remote control through a solenoid mounted on the rear of the gun. Recoil and counter-recoil were controlled hydraulically by means of a piston and spring combination connected to the recoiling mechanism and operating in an oil-filled recuperator cylinder mounted to the stationar ...
