Coastal Artillery
Coastal artillery is the branch of the armed forces concerned with operating anti-ship artillery or fixed gun batteries in coastal fortifications. From the Middle Ages until World War II, coastal artillery and naval artillery in the form of cannons were highly important to military affairs and generally represented the areas of highest technology and capital cost among materiel. The advent of 20th-century technologies, especially military aviation, naval aviation, jet aircraft, and guided missiles, reduced the primacy of cannons, battleships, and coastal artillery. In countries where coastal artillery has not been disbanded, these forces have acquired amphibious capabilities. In littoral warfare, mobile coastal artillery armed with surface-to-surface missiles can still be used to deny the use of sea lanes. It was long held as a rule of thumb that one shore-based gun equaled three naval guns of the same caliber, due to the steadiness of the coastal gun which allowed ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fort Delaware
Fort Delaware is a former harbor defense facility, designed by chief engineer Joseph Gilbert Totten and located on Pea Patch Island in the Delaware River.Dobbs, Kelli W., et al.

Chesapeake & Delaware Canal
The Chesapeake & Delaware Canal (C&D Canal) is a -long, -wide and -deep ship canal that connects the Delaware River with the Chesapeake Bay in the states of Delaware and Maryland in the United States. In the mid-17th century, mapmaker Augustine Herman observed that these great bodies of water were separated only by a narrow strip of land. In 1764, a survey of possible water routes across the Delmarva Peninsula was made, but little action followed. The idea was raised again in 1788 by regional business leaders, including famed Philadelphians Benjamin Franklin and Benjamin Rush. Despite the beginnings of a commercial venture in 1802 coincident with Canal Mania in England and Wales, it was not until 1829 until the C&D Canal Company could, at last, announce the waterway "open for business". Its construction cost of $3.5 million (equivalent to $ million in ) made it one of the most expensive canal projects of its time. In the present era, the C&D Canal is owned and operated ...
