Puerto Castilla, Honduras
Puerto Castilla is a village in the Colón Department of Honduras located approximately north of Trujillo. This port city on the Caribbean Sea (Atlantic Ocean) was the one-time site of the United Fruit Company's Castilla Division which specialized in the growth, cultivation and shipments of the Gros Michel banana. This division was closed in the late 1930s as a result of 'Panama disease', a blight on the roots of the banana. The port city, and its population were moved east on the peninsula in the 1940s when a small naval base was established there for a PBY Catalina seaplane base. During World War II the seaplane base supported military operations including surveillance and security in conjunction with Guantanamo Bay, Cuba. It was believed that German naval forces planned an attack on the Panama Canal causing bases like Puerto Castilla and many others along the coast toward Panama to be on high alert. Puerto Castilla is now a native fishing village of about six hundred re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ships Built In Mobile, Alabama
A ship is a large watercraft that travels the world's oceans and other sufficiently deep waterways, carrying cargo or passengers, or in support of specialized missions, such as defense, research, and fishing. Ships are generally distinguished from boats, based on size, shape, load capacity, and purpose. Ships have supported exploration, trade, warfare, migration, colonization, and science. After the 15th century, new crops that had come from and to the Americas via the European seafarers significantly contributed to world population growth. Ship transport is responsible for the largest portion of world commerce. The word ''ship'' has meant, depending on the era and the context, either just a large vessel or specifically a ship-rigged sailing ship with three or more masts, each of which is square-rigged. As of 2016, there were more than 49,000 merchant ships, totaling almost 1.8 billion dead weight tons. Of these 28% were oil tankers, 43% were bulk carriers, and 13% were cont ...

Philadelphia Naval Yard
The Philadelphia Naval Shipyard was an important naval shipyard of the United States for almost two centuries. Philadelphia's original navy yard, begun in 1776 on Front Street and Federal Street in what is now the Pennsport section of the city, was the first naval shipyard of the United States. It was replaced by a new, much larger yard developed around facilities begun in 1871 on League Island, at the confluence of the Delaware and Schuylkill rivers. The Navy Yard expansion stimulated the development over time of residential and businesses in South Philadelphia, where many shipyard workers lived. During World War II, some 40,000 workers operated on shifts around the clock to produce and repair ships at the yard for the war effort. The United States Navy ended most of its activities there in the 1990s, closing its base after recommendations by the Base Realignment and Closure commission. In 2000, the Philadelphia Industrial Development Corporation, on behalf of the city of Ph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aerostat
An aerostat (, via French) is a lighter-than-air aircraft that gains its lift through the use of a buoyant gas. Aerostats include unpowered balloons and powered airships. A balloon may be free-flying or tethered. The average density of the craft is lower than the density of atmospheric air, because its main component is one or more gasbags, a lightweight skin containing a lifting gas (which could be heated air or any gas of lower density than air) to provide buoyancy, to which other components such as a gondola containing equipment or people are attached. Especially with airships, the gasbags are often protected by an outer envelope. Aerostats are so named because they use aerostatic lift which is a buoyant force that does not require movement through the surrounding air mass, resulting in VTOL ability. This contrasts with the heavy aerodynes that primarily use aerodynamic lift which requires the movement of a wing surface through the surrounding air mass. The term has also be ...

Rigid-hulled Inflatable Boat
A rigid inflatable boat (RIB), also rigid-hull inflatable boat or rigid-hulled inflatable boat (RHIB), is a lightweight but high-performance and high-capacity boat constructed with a rigid hull bottom joined to side-forming air tubes that are inflated with air to a high pressure so as to give the sides resilient rigidity along the boat's topsides. The design is stable, light, fast and seaworthy. The inflated collar acts as a life jacket, ensuring that the vessel retains its buoyancy, even if the boat is taking on water. The RIB is an evolutionary development of the inflatable boat with a rubberized fabric bottom that is stiffened with flat boards within the collar to form the deck or floor of the boat. History Origins in Wales The combination of rigid hull and large inflatable buoyancy tubes had been conceived by a Royal National Lifeboat Institution (RNLI) team working under Inspector of Lifeboats Dag Pike in 1964 as a means of reducing the wear and tear of the fabric botto ...

Liberia
Liberia (), officially the Republic of Liberia, is a country on the West African coast. It is bordered by Sierra Leone to Liberia–Sierra Leone border, its northwest, Guinea to its north, Ivory Coast to its east, and the Atlantic Ocean to its south and southwest. It has a population of around 5 million and covers an area of . English is the official language, but over 20 indigenous languages are spoken, reflecting the country's ethnic and cultural diversity. The country's capital and largest city is Monrovia. Liberia began in the early 19th century as a project of the American Colonization Society (ACS), which believed black people would face better chances for freedom and prosperity in Africa than in the United States. Between 1822 and the outbreak of the American Civil War in 1861, more than 15,000 freed and free-born black people who faced social and legal oppression in the U.S., along with 3,198 Afro-Caribbeans, relocated to Liberia. Gradually developing an Americo- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Naval Amphibious Base Little Creek
A navy, naval force, or maritime force is the branch of a nation's armed forces principally designated for naval and amphibious warfare; namely, lake-borne, riverine, littoral, or ocean-borne combat operations and related functions. It includes anything conducted by surface ships, amphibious ships, submarines, and seaborne aviation, as well as ancillary support, communications, training, and other fields. The strategic offensive role of a navy is projection of force into areas beyond a country's shores (for example, to protect sea-lanes, deter or confront piracy, ferry troops, or attack other navies, ports, or shore installations). The strategic defensive purpose of a navy is to frustrate seaborne projection-of-force by enemies. The strategic task of the navy also may incorporate nuclear deterrence by use of submarine-launched ballistic missiles. Naval operations can be broadly divided between riverine and littoral applications (brown-water navy), open-ocean applications ( b ...

Drydock
A dry dock (sometimes drydock or dry-dock) is a narrow basin or vessel that can be flooded to allow a load to be floated in, then drained to allow that load to come to rest on a dry platform. Dry docks are used for the construction, maintenance, and repair of ships, boats, and other watercraft. History Greco-Roman world The Greek author Athenaeus of Naucratis (V 204c-d) reports something that may have been a dry dock in Ptolemaic Egypt in the reign of Ptolemy IV Philopator (221-204 BC) on the occasion of the launch of the enormous ''Tessarakonteres'' rowing ship. It has been calculated that a dock for a vessel of such a size might have had a volume of 750,000 gallons of water. In Roman times, a shipyard at Narni, which is still studied, may have served as a dry dock. Medieval China The use of dry docks in China goes at least as far back the 10th century A.D. In 1088, Song Dynasty scientist and statesman Shen Kuo (1031–1095) wrote in his '' Dream Pool Essays'': Renais ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
