Zalinski Boat Under Construction
Edmund Louis Gray Zalinski, (December 13, 1849 – March 11, 1909) was a Polish-born American soldier, military engineer and inventor. He is best known for the development of the pneumatic dynamite torpedo-gun. Early life and military service Zalinski was born to a Jewish family in Kórnik, Prussian Poland on December 13, 1849, and emigrated with his parents to the United States in 1853. He began school in Seneca Falls, New York and attended high school in Syracuse until 1863, when he dropped out at the age of 15. Lying about his age, Zalinski enlisted in the United States Army, and served during the American Civil War as aide-de-camp on the staff of General Nelson A. Miles from October 1864. In February 1865, he was commissioned a second lieutenant in the Second New York Heavy Artillery Regiment, having been recommended for promotion for gallant and meritorious conduct at the Battle of Hatcher's Run, Virginia.

5th Air Defense Artillery Regiment
The 5th Air Defense Artillery Regiment is an Air Defense Artillery regiment of the United States Army, first formed in 1861 in the Regular Army as the 5th Regiment of Artillery. Lineage On 4 May 1861, in conformity with the proclamation of the President, a new regiment of 12 batteries was added to the artillery arm of service and became known as the Fifth of the series. Congress confirmed this act of the President, 12 July (approved 29 July) of the same year, but all appointments dated from 14 May. The regiment was constituted on 18 June 1861 and organized on 4 July at Camp Greble, Pennsylvania, where the regiment initially assembled and trained. Differing in organization from the older regiments, the new one comprised only field batteries, being in this regard the first entire regiment so equipped in the Regular Army. But it must not be inferred that the Fifth was designated by law as a light artillery regiment. "Nowhere in the act of 29 July do the words 'field or light artill ...

Telescopic Sight
A telescopic sight, commonly called a scope informally, is an optical sighting device based on a refracting telescope. It is equipped with some form of a referencing pattern – known as a ''reticle'' – mounted in a focally appropriate position in its optical system to provide an accurate point of aim. Telescopic sights are used with all types of systems that require magnification in addition to reliable visual aiming, as opposed to non-magnifying iron sights, reflector (reflex) sights, holographic sights or laser sights, and are most commonly found on long-barrel firearms, particularly rifles, usually via a scope mount. The optical components may be combined with optoelectronics to add night vision or smart device features. History The first experiments directed to give shooters optical aiming aids go back to the early 17th century. For centuries, different optical aiming aids and primitive predecessors of telescopic sights were created that had practical or pe ...

Rifling
In firearms, rifling is machining helical grooves into the internal (bore) surface of a gun's barrel for the purpose of exerting torque and thus imparting a spin to a projectile around its longitudinal axis during shooting to stabilize the projectile longitudinally by conservation of angular momentum, improving its aerodynamic stability and accuracy over smoothbore designs. Rifling is characterized by its twist rate, which indicates the distance the rifling takes to complete one full revolution, such as "1 turn in 10 inches" (1:10 inches), "1 turn in 254 mm" ("1:254 mm" or "1:25.4 cm)", or the like. Normally, an experienced shooter can infer the units of measurement from the numbers alone. A shorter distance indicates a faster twist, meaning that for a given velocity the projectile will rotate at a higher spin rate. The combination of length, weight, and shape of a projectile determines the twist rate needed to gyroscopically stabilize it – barrel ...

Detonator
A detonator, frequently a blasting cap, is a device used to trigger an explosive device. Detonators can be chemically, mechanically, or electrically initiated, the last two being the most common. The commercial use of explosives uses electrical detonators or the capped fuse which is a length of safety fuse to which an ordinary detonator has been joined. Many detonators' primary explosive is a material called ASA compound. This compound is formed from lead azide, lead styphnate and aluminium and is pressed into place above the base charge, usually TNT or tetryl in military detonators and PETN in commercial detonators. Other materials such as DDNP (diazo dinitro phenol) are also used as the primary charge to reduce the amount of lead emitted into the atmosphere by mining and quarrying operations. Old detonators used mercury fulminate as the primary, often mixed with potassium chlorate to yield better performance. A blasting cap is a small sensitive primary explosive device ge ...

Fort Totten (Queens)
Fort Totten is a former active United States Army installation in the New York City Borough (New York City), borough of Queens. It is located on the Willets Point peninsula on the north shore of Long Island. Fort Totten is at the head of Little Neck Bay, where the East River widens to become Long Island Sound. While the U.S. Army Reserve continues to maintain a presence at the fort, the property is now owned by the City of New York. History Civil War era Construction began on the Fort at Willets Point in 1862 (named Fort Totten in 1898), after the land was purchased by the U.S. Government in 1857 from the Willets family. The fort is close to the Queens neighborhoods of Bay Terrace, Queens, Bay Terrace, Bayside, Queens, Bayside, Beechhurst, Queens, Beechhurst and Whitestone, Queens, Whitestone.

Submarine Mines In United States Harbor Defense
The modern era of defending American harbors with controlled mines or submarine mines (originally referred to as "torpedoes") began in the post-Civil War period, and was a major part of US harbor defenses from circa 1900 to 1947. Brief history In 1866, the United States Army Corps of Engineers established the Engineer School of Application at Willets Point, New York. The first commander of this school, Major Henry Larcom Abbot, was almost single-handedly responsible for designing and supervising the program of research and development that defined the strategy and tactics for the mine defense of American harbors. Abbot experimented with underwater explosives, fuzes, cabling, and electrical equipment for over a decade before publishing the first manuals on the use of mines in coast defense in 1876–77. At least one experimental controlled minefield was emplaced at this time, at Fort Mifflin in Pennsylvania. However, funding of the fortification program of the 1870s was cancell ...

Fort Monroe
Fort Monroe, managed by partnership between the Fort Monroe Authority for the Commonwealth of Virginia, the National Park Service as the Fort Monroe National Monument, and the City of Hampton, is a former military installation in Hampton, Virginia, at Old Point Comfort, the southern tip of the Virginia Peninsula, United States. Along with Fort Wool, Fort Monroe originally guarded the navigation channel between the Chesapeake Bay and Hampton Roads—the natural roadstead at the confluence of the Elizabeth, the Nansemond and the James rivers. Union General George B. McClellan landed his forces at the fort during Peninsula campaign of 1862 during the American Civil War. Until disarmament in 1946, the areas protected by the fort were the entire Chesapeake Bay and Potomac River regions, including the water approaches to the cities of Washington, D.C. and Baltimore, Maryland, along with important shipyards and naval bases in the Hampton Roads area. Surrounded by a moat, the six-side ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Military Science
Military science is the study of military processes, institutions, and behavior, along with the study of warfare, and the theory and application of organized coercive force. It is mainly focused on theory, method, and practice of producing military capability in a manner consistent with national defense policy. Military science serves to identify the strategic, political, economic, psychological, social, operational, technological, and tactical elements necessary to sustain relative advantage of military force; and to increase the likelihood and favorable outcomes of victory in peace or during a war. Military scientists include theorists, researchers, experimental scientists, applied scientists, designers, engineers, test technicians, and other military personnel. Military personnel obtain weapons, equipment, and training to achieve specific strategic goals. Military science is also used to establish enemy capability as part of technical intelligence.
