LÉ Niamh (P52)
LÉ ''Niamh'' (P52) is a in the Irish Naval Service. The ship is named after Niamh, queen of Tír na nÓg, from Irish mythology. Commissioned in 2001, the ship was in active service. Design The ship was designed by STX Canada Marine (formerly Kvaerner Masa Marine) and has an all-steel hull based on the Mauritian patrol vessel launched in 1995, but without the helicopter deck and hangar facilities. The level of automation incorporated into the ship's systems allows the ship to be operated with just 44 crew including six officers. The vessel is designed for winter North Atlantic operations. Weapons systems The ship is armed with an OTO Melara 76 mm dual purpose gun installed on the bow gun deck. The gun fires shells and is capable of firing up to 85 rounds per minute to a range of over . It also has two 12.7 mm (.50 inch) machine guns and two 20 mm Rheinmetall Rh202 Canon for anti-aircraft defence. The main gun is controlled by an Ultra Electronics Command and Co ...

Niamh (mythology)
Niamh or Niam () is the lover or spouse of Oisín, son of Fionn mac Cumhail, in the Fianna Cycle of Irish mythology. In the story of Golden-headed Niamh or Golden-haired Niamh ( ga, Niaṁ Cinn-Óir, Niamh Cinn-Óir, italic=no), an otherworldly woman who carried away Oisín to live with her in her domain of Tír na nÓg, the Land of Youth. She had two sons and a daughter with Oisín. After more than 300 years of living together, Niamh reluctantly allowed Oisín to visit Ireland, imposing on him a taboo not to touch the ground there, and once he did, he turned old and was unable to go back to see Niamh ever again. In the medieval version, Niamh was a mortal princess of Munster who eloped with Oisín to Ulster but committed suicide when her father's army arrived in pursuit. Summary The familiar story of Niamh of Tír na nÓg was described in a poem around 1750 attributed to Mícheál Coimín (1676–1760), and summarized as follows: :Niamh came from beyond the sea westwards, ri ...

Cork Harbour
Cork Harbour () is a natural harbour and river estuary at the mouth of the River Lee in County Cork, Ireland. It is one of several which lay claim to the title of "second largest natural harbour in the world by navigational area" (after Port Jackson, Sydney). Other contenders include Halifax Harbour in Canada, Trincomalee Harbour in Sri Lanka and Poole Harbour in England. The harbour has been a working port and a strategic defensive hub for centuries, and it has been one of Ireland's major employment hubs since the early 1900s. Traditional heavy industries have waned since the late 20th century, with the likes of the closure of Irish Steel in Haulbowline and shipbuilding at Verolme. It still has strategic significance in energy generation, shipping, refining and pharmaceuticals development. Geography The main tributary to the harbour is the River Lee which, after flowing through Cork city, passes through the upper harbour ( Lough Mahon) in the northwest before passing to t ...

Haulbowline
Haulbowline ( ga, Inis Sionnach; non, Ál-boling) is an island in Cork Harbour off the coast of Ireland. The world's first yacht club was founded on Haulbowline in 1720. The western side of the island is the main naval base and headquarters for the Irish Naval Service, with the eastern side previously used for heavy industry and later redeveloped as a park. Since 1966 the island has been connected to the mainland by a roadbridge. Etymology The island's name may derive from Old Norse ''ál-boling'' or similar = "eel dwelling" ("area where there are conger eels"). The 17th and 18th-century spellings end in "-ing"; there may have been nautical influence on the spelling later. The Irish language name for the island, ''Inis Sionnach'', translates to "island of the foxes". Demographics Naval history At a strategic and deepwater position in the harbour, the island has long been a military base. The island was first fortified in 1602, and initially an important base for the Brit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Devon
Devon ( , historically known as Devonshire , ) is a ceremonial and non-metropolitan county in South West England. The most populous settlement in Devon is the city of Plymouth, followed by Devon's county town, the city of Exeter. Devon is a coastal county with cliffs and sandy beaches. Home to the largest open space in southern England, Dartmoor (), the county is predominately rural and has a relatively low population density for an English county. The county is bordered by Somerset to the north east, Dorset to the east, and Cornwall to the west. The county is split into the non-metropolitan districts of East Devon, Mid Devon, North Devon, South Hams, Teignbridge, Torridge, West Devon, Exeter, and the unitary authority areas of Plymouth, and Torbay. Combined as a ceremonial county, Devon's area is and its population is about 1.2 million. Devon derives its name from Dumnonia (the shift from ''m'' to ''v'' is a typical Celtic consonant shift).

Kilonewton
The newton (symbol: N) is the unit of force in the International System of Units (SI). It is defined as 1 kg⋅m/s, the force which gives a mass of 1 kilogram an acceleration of 1 metre per second per second. It is named after Isaac Newton in recognition of his work on classical mechanics, specifically Newton's second law of motion. Definition A newton is defined as 1 kg⋅m/s (it is a derived unit which is defined in terms of the SI base units). One newton is therefore the force needed to accelerate one kilogram of mass at the rate of one metre per second squared in the direction of the applied force. The units "metre per second squared" can be understood as measuring a rate of change in velocity per unit of time, i.e. an increase in velocity by 1 metre per second every second. In 1946, Conférence Générale des Poids et Mesures (CGPM) Resolution 2 standardized the unit of force in the MKS system of units to be the amount needed to accelerate 1 kilogram of mass at the rate ...

Revolutions Per Minute
Revolutions per minute (abbreviated rpm, RPM, rev/min, r/min, or with the notation min−1) is a unit of rotational speed or rotational frequency for rotating machines. Standards ISO 80000-3:2019 defines a unit of rotation as the dimensionless unit equal to 1, which it refers to as a revolution, but does not define the revolution as a unit. It defines a unit of rotational frequency equal to s−1. The superseded standard ISO 80000-3:2006 did however state with reference to the unit name 'one', symbol '1', that "The special name revolution, symbol r, for this unit is widely used in specifications on rotating machines." The International System of Units (SI) does not recognize rpm as a unit, and defines the unit of frequency, Hz, as equal to s−1. :\begin 1~&\text &&=& 60~&\text \\ \frac~&\text &&=& 1~&\text \end A corresponding but distinct quantity for describing rotation is angular velocity, for which the SI unit is the ...
