Ukrainian Patrol Vessel Sloviansk
The Ukrainian patrol vessel ''Sloviansk'' (P190) was an of the Naval Forces of Armed Forces of Ukraine. Originally named USCGC ''Cushing'' when in service with the United States Coast Guard, the vessel was acquired by Ukraine in 2018. She was built at Bollinger Shipyards in Lockport, Louisiana, in early 1988 and commissioned on 4 August 1988, at Coast Guard Base Mobile, Alabama. She was homeported in Atlantic Beach, North Carolina. On 8 March 2017 ''Cushing'' was decommissioned along with USCGC ''Nantucket'' in North Carolina. Two s replaced both cutters the following year. Design and construction The s were constructed in Bollinger Shipyards, Lockport, Louisiana. ''Cushing'' has an overall length of . It had a beam of and a draft of at the time of construction. The patrol boat has a displacement of at full load and at half load. It is powered by two Paxman Valenta 16 CM diesel engines or two Caterpillar 3516 diesel engines. It has two 3304T diesel generators made by Cate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cushing Island, Maine
Cushing Island, or Cushing's Island, is a privately owned island in Casco Bay in the U.S. state of Maine. Part of the city of Portland, Maine, roughly 45 families live there seasonally. History In 1623-24 English explorer Christopher Levett built a blockhouse on the island, part of granted him by the English King. Levett left behind a group of settlers to carry on after he returned to England. But the naval captain and adventurer never returned, and the fate of the men is unknown. After Levett's occupation the island was known as Andrews Island. Levett's early settlement earned him the sobriquet "the pioneer colonist in Casco Bay" from eminent Maine historian James Phinney Baxter. After a host of owners, in September 1734, Nathaniel Jones conveyed the island to Joshua Bangs. The island was then known as 'Bangs Island'. The name 'Bangs Island' will be found on maps from the period. In the late 1750s Ezekiel Cushing obtained the island from Bangs. In 1760, Bangs regained the is ...

Draft (ship)
The draft or draught of a ship's hull is the vertical distance between the waterline and the bottom of the hull (keel). The draught of the vessel is the maximum depth of any part of the vessel, including appendages such as rudders, propellers and drop keels if deployed. Draft determines the minimum depth of water a ship or boat can safely navigate. The related term air draft is the maximum height of any part of the vessel above the water. The more heavily a vessel is loaded, the deeper it sinks into the water, and the greater its draft. After construction, the shipyard creates a table showing how much water the vessel displaces based on its draft and the density of the water (salt or fresh). The draft can also be used to determine the weight of cargo on board by calculating the total displacement of water, accounting for the content of the ship's bunkers, and using Archimedes' principle. The closely related term "trim" is defined as the difference between the forward and aft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caribbean Sea
The Caribbean Sea ( es, Mar Caribe; french: Mer des Caraïbes; ht, Lanmè Karayib; jam, Kiaribiyan Sii; nl, Caraïbische Zee; pap, Laman Karibe) is a sea of the Atlantic Ocean in the tropics of the Western Hemisphere. It is bounded by Mexico and Central America to the west and southwest, to the north by the Greater Antilles starting with Cuba, to the east by the Lesser Antilles, and to the south by the northern coast of South America. The Gulf of Mexico lies to the northwest. The entire area of the Caribbean Sea, the numerous islands of the West Indies, and adjacent coasts are collectively known as the Caribbean. The Caribbean Sea is one of the largest seas and has an area of about . The sea's deepest point is the Cayman Trough, between the Cayman Islands and Jamaica, at below sea level. The Caribbean coastline has many gulfs and bays: the Gulf of Gonâve, Gulf of Venezuela, Gulf of Darién, Golfo de los Mosquitos, Gulf of Paria and Gulf of Honduras. The Caribbean Sea has ...

Gulf Of Mexico
The Gulf of Mexico ( es, Golfo de México) is an oceanic basin, ocean basin and a marginal sea of the Atlantic Ocean, largely surrounded by the North American continent. It is bounded on the northeast, north and northwest by the Gulf Coast of the United States; on the southwest and south by the Mexico, Mexican States of Mexico, states of Tamaulipas, Veracruz, Tabasco, Campeche, Yucatan, and Quintana Roo; and on the southeast by Cuba. The Southern United States, Southern U.S. states of Texas, Louisiana, Mississippi, Alabama, and Florida, which border the Gulf on the north, are often referred to as the "Third Coast" of the United States (in addition to its Atlantic and Pacific Ocean, Pacific coasts). The Gulf of Mexico took shape approximately 300 million years ago as a result of plate tectonics.Huerta, A.D., and D.L.

Portland, Maine
Portland is the largest city in the U.S. state of Maine and the seat of Cumberland County. Portland's population was 68,408 in April 2020. The Greater Portland metropolitan area is home to over half a million people, the 104th-largest metropolitan area in the United States. Portland's economy relies mostly on the service sector and tourism. The Old Port is known for its nightlife and 19th-century architecture. Marine industry plays an important role in the city's economy, with an active waterfront that supports fishing and commercial shipping. The Port of Portland is the second-largest tonnage seaport in New England. The city seal depicts a phoenix rising from ashes, a reference to recovery from four devastating fires. Portland was named after the English Isle of Portland, Dorset. In turn, the city of Portland, Oregon was named after Portland, Maine. The word ''Portland'' is derived from the Old English word ''Portlanda'', which means "land surrounding a harbor". The Greater ...

Coast Guard Day
Coast Guard Day is held every August 4 to commemorate the founding of the United States Coast Guard as the Revenue Marine on August 4, 1790, by then-Secretary of the Treasury Alexander Hamilton. On that date, U.S. Congress, guided by Hamilton, authorized the building of a fleet of the first ten Revenue Service cutters, whose responsibility would be enforcement of the first tariff laws enacted by the U.S. Congress under the U.S. Constitution.Krietemeyer, p 5 Background The U.S. Coast Guard received its present name through an act of the U.S. Congress signed into law by U.S. President Woodrow Wilson on January 28, 1915 that merged the Revenue Cutter Service with the U.S. Life-Saving Service, and provided the nation with a single maritime service dedicated to saving life at sea and enforcing the nation's maritime laws.Johnson, p 32King, p 240 The U.S. Coast Guard began to maintain the country's maritime aids to navigation, including operating U.S. lighthouses, when President Fra ...

Loran-C
Loran-C is a hyperbolic radio navigation system that allows a receiver to determine its position by listening to low frequency radio signals that are transmitted by fixed land-based radio beacons. Loran-C combined two different techniques to provide a signal that was both long-range and highly accurate, features that had been incompatible. Its disadvantage was the expense of the equipment needed to interpret the signals, which meant that Loran-C was used primarily by militaries after it was introduced in 1957. By the 1970s, the cost, weight and size of electronics needed to implement Loran-C had been dramatically reduced because of the introduction of solid-state electronics and, from the mid-1970s, early microcontrollers to process the signal. Low-cost and easy-to-use Loran-C units became common from the late 1970s, especially in the early 1980s, and the earlier LORAN system was discontinued in favor of installing more Loran-C stations around the world. Loran-C became one of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
M2 Browning
The M2 machine gun or Browning .50 caliber machine gun (informally, "Ma Deuce") is a heavy machine gun that was designed towards the end of World War I by John Browning. Its design is similar to Browning's earlier M1919 Browning machine gun, which was chambered for the .30-06 cartridge. The M2 uses Browning's larger and more powerful .50 BMG (12.7 mm) cartridge. The design has had many designations; the official U.S. military designation for the current infantry type is Browning Machine Gun, Cal. .50, M2, HB, Flexible. It is effective against infantry, unarmored or lightly armored vehicles and boats, light fortifications, and low-flying aircraft. The gun has been used extensively as a vehicle weapon and for aircraft armament by the United States since the 1930s. It was heavily used during World War II, the Korean War, the Vietnam War, the Falklands War, the Soviet–Afghan War, the Gulf War, the Iraq War, and the War in Afghanistan. It is the primary heavy machine gun of NATO ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Superstructure
A superstructure is an upward extension of an existing structure above a baseline. This term is applied to various kinds of physical structures such as buildings, bridges, or ships. Aboard ships and large boats On water craft, the superstructure consists of the parts of the ship or a boat, including sailboats, fishing boats, passenger ships, and submarines, that project above her main deck. This does not usually include its masts or any armament turrets. Note that in modern times, turrets do not always carry naval artillery, but they can also carry missile launchers and/or antisubmarine warfare weapons. The size of a watercraft's superstructure can have many implications in the performance of ships and boats, since these structures can alter their structural rigidity, their displacements, and/or stability. These can be detrimental to any vessel's performance if they are taken into consideration incorrectly. The height and the weight of superstructure on board a ship or a bo ...

Motor–generator
A motor–generator (an M–G set) is a device for converting electrical power to another form. Motor–generator sets are used to convert frequency, voltage, or phase of power. They may also be used to isolate electrical loads from the electrical power supply line. Large motor–generators were widely used to convert industrial amounts of power while smaller motor–generators (such as the one shown in the picture) were used to convert battery power to higher DC voltages. While a motor–generator set may consist of distinct motor and generator machines coupled together, a single unit dynamotor (for dynamo–motor) has the motor coils and the generator coils wound around a single rotor; both the motor and generator therefore share the same outer field coils or magnets.Radio Amateur's Handbook 1976, pub. |
