Honda Point Disaster
The Honda Point disaster was the largest peacetime loss of U.S. Navy ships. On the evening of September 8, 1923, seven destroyers, while traveling at 20 knots (37 km/h), ran aground at Honda Point (also known as Point Pedernales; the cliffs just off-shore called Devil's Jaw), a few miles from the northern side of the Santa Barbara Channel off Point Arguello on the Gaviota Coast in Santa Barbara County, California. Two other ships grounded, but were able to maneuver free off the rocks. Twenty-three sailors died in the disaster. Geography of Honda Point The area of Honda Point is extremely treacherous for central California mariners, as it features a series of rocky outcroppings, collectively known as Woodbury Rocks (one of which is today named Destroyer Rock on navigational charts). Called the Devil's Jaw, the area has been a navigational hazard since the Spanish explorers first came in the 16th century. It is just north of the entrance to the Santa Barbara Channel, w ...

Point Arguello
Point Arguello ( Spanish: ''Punta Argüello'') is a headland on the Gaviota Coast, in Santa Barbara County, California, near the city of Lompoc. The area was first used by the United States Navy in 1959 for the launch of military and sounding rockets. It was transferred to the United States Air Force in 1964, at which time it became part of Vandenberg Air Force Base. History In 1769, the Spanish Portola expedition became the first Europeans to explore this area by land. Soldiers of the expedition named a nearby point Los Pedernales or Punta Pedernales, because they found flints there. The entire point was given that name on some early maps but, in 1792, British naval explorer George Vancouver dubbed it Point Arguello, for José Darío Argüello, a Spanish frontier soldier who was Commandant of the Presidio of Santa Barbara and acting governor of Alta California. A High-frequency direction finding (HFDF) was established here by the Navy during World War II. These radi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lieutenant Commander
Lieutenant commander (also hyphenated lieutenant-commander and abbreviated Lt Cdr, LtCdr. or LCDR) is a commissioned officer rank in many navies. The rank is superior to a lieutenant and subordinate to a commander. The corresponding rank in most armies and air forces is major, and in the Royal Air Force and other Commonwealth air forces is squadron leader. The NATO rank code is mostly OF-3. A lieutenant commander is a department officer or the executive officer ( second-in-command) on many warships and smaller shore installations, or the commanding officer of a smaller ship/installation. They are also department officers in naval aviation squadrons. Etymology Most Commonwealth and other navies address lieutenant commanders by their full rank or the positions they occupy ("captain" if in command of a vessel). The United States Navy, however, addresses officers by their full rank or the higher grade of the rank. For example, oral communications in formal and info ...

Radio
Radio is the technology of signaling and communicating using radio waves. Radio waves are electromagnetic waves of frequency between 30 hertz (Hz) and 300 gigahertz (GHz). They are generated by an electronic device called a transmitter connected to an antenna which radiates the waves, and received by another antenna connected to a radio receiver. Radio is very widely used in modern technology, in radio communication, radar, radio navigation, remote control, remote sensing, and other applications. In radio communication, used in radio and television broadcasting, cell phones, two-way radios, wireless networking, and satellite communication, among numerous other uses, radio waves are used to carry information across space from a transmitter to a receiver, by modulating the radio signal (impressing an information signal on the radio wave by varying some aspect of the wave) in the transmitter. In radar, used to locate and track objects like aircraft, ships, sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dead Reckoning
In navigation, dead reckoning is the process of calculating current position of some moving object by using a previously determined position, or fix, and then incorporating estimates of speed, heading direction, and course over elapsed time. The corresponding term in biology, used to describe the processes by which animals update their estimates of position or heading, is path integration. Dead reckoning is subject to cumulative errors. Advances in navigational aids that give accurate information on position, in particular satellite navigation using the Global Positioning System, have made simple dead reckoning by humans obsolete for most purposes. However, inertial navigation systems, which provide very accurate directional information, use dead reckoning and are very widely applied. Etymology The term "dead reckoning" was not originally used to abbreviate "deduced reckoning," nor is it a misspelling of the term "ded reckoning." The use of "ded" or "deduced reckoning" ...

San Diego Bay
San Diego Bay is a natural harbor and deepwater port located in San Diego County, California near the U.S.–Mexico border. The bay, which is long and wide, is the third largest of the three large, protected natural bays on California's of coastline, after San Francisco Bay and Humboldt Bay. The highly urbanized land adjacent to the bay includes the city of San Diego (eighth-largest in the United States) and four other cities: National City, Chula Vista, Imperial Beach and Coronado. Considered to be one of the best natural harbors on the west coast of North America, it was colonized by Spain beginning in 1769. Later it served as base headquarters of major ships of the United States Navy in the Pacific until just before the United States entered World War II, when the newly organized United States Pacific Fleet primary base was transferred to Pearl Harbor, Hawaii. However, San Diego Bay remains as a home port of major assets, including several aircraft carriers, of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
San Francisco Bay
San Francisco Bay is a large tidal estuary in the U.S. state of California, and gives its name to the San Francisco Bay Area. It is dominated by the big cities of San Francisco, San Jose, and Oakland. San Francisco Bay drains water from approximately 40 percent of California. Water from the Sacramento and San Joaquin rivers, and from the Sierra Nevada mountains, flow into Suisun Bay, which then travels through the Carquinez Strait to meet with the Napa River at the entrance to San Pablo Bay, which connects at its south end to San Francisco Bay. It then connects to the Pacific Ocean via the Golden Gate strait. However, this entire group of interconnected bays is often called the ''San Francisco Bay''. The bay was designated a Ramsar Wetland of International Importance on February 2, 2017. Size The bay covers somewhere between , depending on which sub-bays (such as San Pablo Bay), estuaries, wetlands, and so on are included in the measurement. The main part of the b ...

Destroyer Squadron
A destroyer squadron is a naval squadron or flotilla usually consisting of destroyers rather than other types of vessel. In some navies other vessels, such as frigates, may be included. In English the word "squadron" tends to be used for larger and "flotilla" for smaller vessels; both may be used for destroyer units. Similar formations are used in non-English-speaking countries, e.g., the "escadrille"—which would translate directly as "squadron"—in France. Royal Navy The Royal Navy began to form units of destroyers after the introduction of 'torpedo boat destroyers' in the early 1900s though pre-World War Two they were usually designated flotillas. RN destroyer units are listed in the main article above examples of some destroyer squadrons below. * 1st Destroyer Squadron, 1947-1970 * 2nd Destroyer Squadron, 1956-1971 * 3rd Destroyer Squadron, 1945-2001 * 4th Destroyer Squadron, 1948-1959 * 5th Destroyer Squadron, 1947-2002 US Navy The U.S. Navy acronym for a destroyer ...

Propeller
A propeller (colloquially often called a screw if on a ship or an airscrew if on an aircraft) is a device with a rotating hub and radiating blades that are set at a pitch to form a helical spiral which, when rotated, exerts linear thrust upon a working fluid such as water or air. Propellers are used to pump fluid through a pipe or duct, or to create thrust to propel a boat through water or an aircraft through air. The blades are specially shaped so that their rotational motion through the fluid causes a pressure difference between the two surfaces of the blade by Bernoulli's principle which exerts force on the fluid. Most marine propellers are screw propellers with helical blades rotating on a propeller shaft (ship), propeller shaft with an approximately horizontal axis. History Early developments The principle employed in using a screw propeller is derived from sculling. In sculling, a single blade is moved through an arc, from side to side taking care to keep presenting the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ship's Bell
A ship's bell is a bell on a ship that is used for the indication of time as well as other traditional functions. The bell itself is usually made of brass or bronze, and normally has the ship's name engraved or cast on it. Strikes Timing of ship's watches Unlike civil clock bells, the strikes of a ship's bell do not accord to the number of the hour. Instead, there are eight bells, one for each half-hour of a four-hour watch. In the age of sailing, watches were timed with a 30-minute hourglass. Bells would be struck every time the glass was turned, and in a pattern of pairs for easier counting, with any odd bells at the end of the sequence. Classical system The classical, or traditional, system was: Most of the crew of a ship would be divided into two to four groups, called watches. Each watch would take its turn with the essential activities of manning the helm, navigating, trimming sails, and keeping a lookout. The hours between 16:00 and 20:00 are so arranged because tha ...
