Fort Casey
Fort Casey State Park is located on Whidbey Island, in Island County, Washington state. It is a Washington state park and a historic district within the U.S. Ebey's Landing National Historical Reserve. Admiralty Inlet was considered so strategic to the defense of Puget Sound in the 1890s that three forts—Fort Casey on Whidbey Island, Fort Flagler on Marrowstone Island, and Fort Worden at Port Townsend—were built with the intention to create a "triangle of fire" against invading ships. This military strategy was based on the theory that the three fortresses would thwart any invasion attempt by sea. History Fort Casey was named for Brigadier General Thomas Lincoln Casey, U.S. Army Chief of Engineers. Designed as part of the massive modernization program of U.S. seacoast fortifications initiated by the Endicott Board, construction on Fort Casey began in 1897. In 1901, the big guns on disappearing carriages, which could be raised out of their protective emplacements so that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Disappearing Gun
A disappearing gun, a gun mounted on a ''disappearing carriage'', is an obsolete type of artillery which enabled a gun to hide from direct fire and observation. The overwhelming majority of carriage designs enabled the gun to rotate backwards and down behind a parapet, or into a pit protected by a wall, after it was fired; a small number were simply barbette mounts on a retractable platform. Either way, retraction lowered the gun from view and direct fire by the enemy while it was being reloaded. It also made reloading easier, since it lowered the breech to a level just above the loading platform, and shells could be rolled right up to the open breech for loading and ramming. Other benefits over non-disappearing types were a higher rate of repetitive fire and less fatigue for the gun crew. Some disappearing carriages were complicated mechanisms, protection from aircraft observation and attack was difficult, and almost all restricted the elevation of the gun. With a few ...

Railway Gun
A railway gun, also called a railroad gun, is a large artillery piece, often surplus naval artillery, mounted on, transported by, and fired from a specially designed railroad car, railway wagon. Many countries have built railway guns, but the best-known are the large Krupp-built pieces used by German Reich, Germany in World War I and World War II. Smaller guns were often part of an armoured train. Only able to be moved where there were good tracks, which could be destroyed by artillery bombardment or airstrike, railway guns were phased out after World War II. Design considerations The design of a railway gun has three firing issues over and above those of an ordinary artillery piece to consider. Namely how the gun is going to be traversed – i.e. moved from side to side to aim; how the horizontal component of the recoil force will be absorbed by the gun's carriage and how the vertical recoil force will be absorbed by the ground. Methods of traverse The first method of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forts In Washington (state)
A fortification is a military construction or building designed for the defense of territories in warfare, and is also used to establish rule in a region during peacetime. The term is derived from Latin ''fortis'' ("strong") and ''facere'' ("to make"). From very early history to modern times, defensive walls have often been necessary for cities to survive in an ever-changing world of invasion and conquest. Some settlements in the Indus Valley civilization were the first small cities to be fortified. In ancient Greece, large stone walls had been built in Mycenaean Greece, such as the ancient site of Mycenae (famous for the huge stone blocks of its 'cyclopean' walls). A Greek '' phrourion'' was a fortified collection of buildings used as a military garrison, and is the equivalent of the Roman castellum or English fortress. These constructions mainly served the purpose of a watch tower, to guard certain roads, passes, and borders. Though smaller than a real fortress, they ...

Pacific Northwest National Scenic Trail
The Pacific Northwest Trail (PNT) is a 1200-mile hiking trail running from the Continental Divide in Montana to the Pacific Ocean on Washington's Olympic Coast. Along the way, the PNT crosses three national parks, seven national forests, and two other national scenic trails. It travels against the grain of several mountain ranges, including the Continental Divide, Whitefish Divide, Purcells, Selkirks, Kettles, Cascades, and Olympics. It was designated as the Pacific Northwest National Scenic Trail by Congress in 2009. History The route was first conceived by Ron Strickland in 1970. Between 1970 and 1976, extensive fieldwork was performed by Strickland and others, including early supporters along the PNT corridor who lent extensive knowledge of local trail systems to the effort. In that time, the Pacific Northwest Trail was cobbled together using preexisting trails and Forest Service roads. In 1977, Strickland founded the Pacific Northwest Trail Association (PNTA), an ...

Admiralty Head Lighthouse
The Admiralty Head Light is a deactivated aid to navigation located on Whidbey Island near Coupeville, Island County, Washington, on the grounds of Fort Casey State Park. The restored lighthouse overlooks Admiralty Inlet. It was the companion to the Point Wilson Light, which sits four miles away on Admiralty Inlet's western shore. History Two lighthouses have been built on Admiralty Head. Only the second remains. Admiralty Head, the east entrance point of Admiralty Inlet, is the southeast extremity of a succession of bluffs extending northward along the western shore of Whidbey Island to Point Partridge, where the bluffs attain their highest elevation. ;Original lighthouse In 1858, the United States purchased on the headland for $400. The original lighthouse was a wooden, two-story house with tower projecting from the gable. It was completed in 1861. It had a fourth order Fresnel lens, which was visible at . In 1890, construction of Fort Casey forced the relocation of the ligh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barbette
Barbettes are several types of gun emplacement in terrestrial fortifications or on naval ships. In recent naval usage, a barbette is a protective circular armour support for a heavy gun turret. This evolved from earlier forms of gun protection that eventually led to the pre-dreadnought. The name ''barbette'' ultimately comes from fortification - it originally meant a raised platform or mound, as in the French phrase ''en barbette'', which refers to the practice of firing a cannon over a parapet rather than through an embrasure in a fortification's casemate. The former gives better angles of fire but less protection than the latter. The disappearing gun was a variation on the barbette gun; it consisted of a heavy gun on a carriage that would retract behind a parapet or into a gunpit for reloading. Barbettes were primarily used in coastal defences, but saw some use in a handful of warships, and some inland fortifications. The term is also used for certain aircraft gun mounts. Sh ...

Fort Wint
Fort Wint was part of the harbor defenses of Manila and Subic Bays built by the Philippine Department of the United States Army between 1907 and 1920 in response to recommendations of the Taft Board prior to the non-fortification clause of the Washington Naval Treaty. Fort Wint was located on Grande Island at the entrance of Subic Bay, approximately 35 miles (56 km) north of Manila Bay. The fort was named for Brigadier General Theodore J. Wint. As specified in the National Defense Act of 1935, this was one of the locations where coastal artillery training was conducted. A battery of the 60th Coast Artillery (AA) was stationed here. Armament Fort Wint was armed with fourteen Taft-Endicott period coast artillery pieces mounted in five batteries. Battery Warwick contained the fort's most powerful weaponry, two M1895 disappearing guns on Buffington-Crozier carriages. Batteries Hall and Woodruff each mounted two M1905 guns, also on disappearing carriages. Batteries Fl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Watertown Arsenal
The Watertown Arsenal was a major American arsenal located on the northern shore of the Charles River in Watertown, Massachusetts. The site is now registered on the ASCE's List of Historic Civil Engineering Landmarks and on the US National Register of Historic Places, and it is home to a park, restaurants, mixed use office space, and currently serves as the national headquarters for athenahealth.

3-inch Gun M1903
The 3-inch gun M1903 and its predecessors the M1898 and M1902 were rapid fire breech-loading artillery guns with a 360-degree traverse. In some references they are called "15-pounders" due to their projectile weight. They were originally emplaced from 1899 to 1917 and served until shortly after World War II. These 3-inch guns were placed to provide fire to protect underwater mines and nets against minesweepers, and also to protect against motor torpedo boats. In some documentation they are called "mine defense guns". The 3-inch guns were mounted on pedestal mounts (or a retractable "masking parapet" mount for the M1898) that bolted into a concrete emplacement that provided cover and safety for the gun's crew. History The 3-inch mine defense guns were part of a comprehensive plan of new fortifications specified by the Board of Fortifications of 1885. The new forts initially included guns up to 12-inch (305 mm) on disappearing carriages, to conceal the fort from obser ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
