RPS Rajah Soliman (D-66)
RPS ''Rajah Soliman'' (D-66) was a destroyer escort/ frigate that served with the Philippine Navy between 1960 and 1964. A , it was originally named during its previous service with the United States Navy. It was the first destroyer escort to be operated by the Philippine Navy, and is the only member of its class ever operated by the service. ''Rajah Soliman'' was also the flagship of the Philippine Navy during its time in commission, which ended with the sinking of the vessel in 1964. Acquisition and service The ex- was transferred to the Philippine Navy on 31 October 1960, as a loan under the terms of the Military Assistance Program; on 21 April 1961, the ship was sold outright to the Philippines. ''Rajah Soliman'' served as the Philippine Navy's flagship during her service life. In June 1964, the ship entered a refit period at the Bataan National Shipyard, located in Mariveles, Bataan, for repairs to her engine. Sinking, raising, and disposal On 29 June 1964, Typhoon Win ...

Philippine Navy
The Philippine Navy (PN) ( tgl, Hukbong Dagat ng Pilipinas, , Sea Army of the Philippines) ( es, Armada de Filipinas, , Ejército del Mar de las Filipinas) is the naval warfare service branch of the Armed Forces of the Philippines. It has an estimated strength of 24,500 active service personnel, including the 8,300-strong Philippine Marine Corps. It operates 82 combat vessels, 14 auxiliary vessels, 25 manned aircraft and 8 unmanned aerial vehicles. It shares the responsibility of patrolling the maritime borders with the Philippine Coast Guard, a formerly attached unit which became a separate maritime law enforcement agency in 1998. History Pre-colonial period Before the Spaniards arrived in the Philippines the ancient native people were already engaging in naval warfare, raiding, trade, piracy, travel and communication using various vessels including balangay. A flotilla of balangay was discovered in the late 1970s in Butuan City, Agusan del Norte. Native Philippine warshi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bataan Peninsula
Bataan (), officially the Province of Bataan ( fil, Lalawigan ng Bataan ), is a province in the Central Luzon region of the Philippines. Its capital is the city of Balanga while Mariveles is the largest town in the province. Occupying the entire Bataan Peninsula on Luzon, Bataan is bordered by the provinces of Zambales and Pampanga to the north. The peninsula faces the South China Sea to the west and Subic Bay to the north-west, and encloses Manila Bay to the east. The Battle of Bataan is known in history as one of the last stands of American and Filipino soldiers before they were overwhelmed by the Japanese forces in World War II. The Bataan Death March was named after the province, where the infamous march started. History Classical Period The first inhabitants of the Bataan peninsula are the Ayta Magbeken people, who are one of the first Negrito ancestors of present-day Filipinos. Later on, Tagalog communities from southern Luzon migrated to parts of Bataan and the Ayta Ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ships Transferred From The United States Navy To The Philippine Navy
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 ...

Frigates Of The Philippine Navy
A frigate () is a type of warship. In different eras, the roles and capabilities of ships classified as frigates have varied somewhat. The name frigate in the 17th to early 18th centuries was given to any full-rigged ship built for speed and maneuverability, intended to be used in scouting, escort and patrol roles. The term was applied loosely to ships varying greatly in design. In the second quarter of the 18th century, the 'true frigate' was developed in France. This type of vessel was characterised by possessing only one armed deck, with an unarmed deck below it used for berthing the crew. Late in the 19th century (British and French prototypes were constructed in 1858), armoured frigates were developed as powerful ironclad warships, the term frigate was used because of their single gun deck. Later developments in ironclad ships rendered the frigate designation obsolete and the term fell out of favour. During the Second World War the name 'frigate' was reintroduced t ...

Hulk (ship)
A hulk is a ship that is afloat, but incapable of going to sea. Hulk may be used to describe a ship that has been launched but not completed, an abandoned wreck or shell, or to refer to an old ship that has had its rigging or internal equipment removed, retaining only its buoyant qualities. The word hulk also may be used as a verb: a ship is "hulked" to convert it to a hulk. The verb was also applied to crews of Royal Navy ships in dock, who were sent to the receiving ship for accommodation, or "hulked". Hulks have a variety of uses such as housing, prisons, salvage pontoons, gambling sites, naval training, or cargo storage. In the days of sail, many hulls served longer as hulks than they did as functional ships. Wooden ships were often hulked when the hull structure became too old and weak to withstand the stresses of sailing. More recently, ships have been hulked when they become obsolete or when they become uneconomical to operate. Sheer hulk A sheer hulk (or shear hulk) w ...

Ship Survey
Vessel safety surveys are inspections of the structure and equipment of a vessel to assess the condition of the surveyed items and check that they comply with legal or classification society requirements for insurance and registration. They may occur at any time when there is reason to suspect that the condition has changed significantly since the previous survey, and the first survey is generally during construction (built under survey) or before first registration. The criteria for acceptance are defined by the licensing or registration authority for a variety of equipment vital to the safe operation of the vessel, such as safety equipment, lifting equipment, hull structure, static stability, ground tackle, propulsion machinery, auxiliary machinery, etc. The SOLAS Convention (International Convention for the Safety of Life at Sea), specifies safety equipment for commercial vessels operating internationally. Classification societies, such as Lloyd's Register (LR), Bureau Verit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subic Naval Base
Naval Base Subic Bay was a major ship-repair, supply, and rest and recreation facility of the Spanish Navy and subsequently the United States Navy located in Zambales, Philippines. The base was 262 square miles, about the size of Singapore. The Navy Exchange had the largest volume of sales of any exchange in the world, and the Naval Supply Depot handled the largest volume of fuel oil of any navy facility in the world. The naval base was the largest overseas military installation of the United States Armed Forces, after Clark Air Base in Angeles City was closed in 1991.Barber, Ben. "Two decades on, Philippines struggles with U.S. base cleanup". '' The American Legion Magazine'', September 2012: 64. Following its closure in 1992, it was transformed into the Subic Bay Freeport Zone by the Philippine government. In late 2022, plans to reopen the base under the Enhanced Defense Cooperation Agreement emerged after the Philippine Navy reoccupied a portion of the base and a U.S. inve ...

Parbuckle Salvage
Parbuckle salvage, or ''parbuckling'', is the righting of a sunken vessel using rotational leverage. A common operation with smaller watercraft, parbuckling is also employed to right large vessels. In 1943, the was rotated nearly 180 degrees to upright after being sunk in the attack on Pearl Harbor, and the Italian cruise ship ''Costa Concordia'' was successfully parbuckled off the west coast of Italy in September 2013, the largest salvage operation of that kind to date. Mechanical advantage and difficulties While the mechanical advantage used by a laborer to parbuckle a cask up an incline is 2:1, parbuckling salvage is not so limited. Each of the 21 winches used to roll the ''Oklahoma'' used cables that passed through two 17-part tackle assemblies (17:1 advantage). Eight diameter sheaves, eight diameter sheaves, and one diameter sheave comprised just half the mechanical effort. A major concern during salvage is preventing rotational torque from becoming a transverse forc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Starboard
Port and starboard are nautical terms for watercraft and aircraft, referring respectively to the left and right sides of the vessel, when aboard and facing the bow (front). Vessels with bilateral symmetry have left and right halves which are mirror images of each other. One asymmetric feature is where access to a boat, ship, or aircraft is at the side, it is usually only on the port side (hence the name). Side Port and starboard unambiguously refer to the left and right side of the vessel, not the observer. That is, the port side of the vessel always refers to the same portion of the vessel's structure, and does not depend on which way the observer is facing. The port side is the side of the vessel which is to the left of an observer aboard the vessel and , that is, facing forward towards the direction the vehicle is heading when underway, and starboard side is to the right of such an observer. This convention allows orders and information to be given unambiguously, witho ... [...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 ...

Storm Surge
A storm surge, storm flood, tidal surge, or storm tide is a coastal flood or tsunami-like phenomenon of rising water commonly associated with low-pressure weather systems, such as cyclones. It is measured as the rise in water level above the normal tidal level, and does not include waves. The main meteorological factor contributing to a storm surge is high-speed wind pushing water towards the coast over a long fetch. Other factors affecting storm surge severity include the shallowness and orientation of the water body in the storm path, the timing of tides, and the atmospheric pressure drop due to the storm. There is a suggestion that climate change may be increasing the hazard of storm surges. Some theorize that as extreme weather becomes more intense and sea level rises due to climate change, storm surge is expected to cause more risk to coastal populations. Communities and governments can adapt by building hard infrastructure, like surge barriers, soft infrastructure, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
