NNS Aradu
NNS ''Aradu'' (F89) (meaning "thunder" in Hausa) is a Nigerian Navy frigate. She is the first of the MEKO 360 general purpose frigates built by the German company, Blohm + Voss. The ship is the largest in the Nigerian Navy. As a general purpose frigate, ''Aradu'' has capabilities for anti-air, anti-surface and anti-submarine warfare effectively, and participated in the 200th anniversary celebrations of the Battle of Trafalgar. The ship also possesses capability for naval fire support and electronic warfare. Additionally, she carries a ship-borne helicopter for anti-submarine warfare, search and rescue, and enhanced surveillance/detection. Design and description The first of the MEKO 360 type frigates, ''Aradu'' was constructed using modular prefabrication and containerised weapons and sensors. The first frigate to be built in this manner, this allowed for speedier construction time. The ship measures at the waterline and overall with a beam of and a draught of . The frig ...

MEKO 360
The MEKO 360 is a class of five ships built in Germany for the Argentine and Nigerian navies. The MEKO 360 was the first version of the MEKO family of vessels built by Blohm und Voss. The type comes in two variants, the MEKO 360H1, comprising one ship, and the MEKO 360H2, comprising four ships. They are alternatively classed as frigates and destroyers by different sources. The design is based on the modular concept which allows swapping out different armaments to fit mission requirements and allows for easier application of upgrades and refits. Variants MEKO 360H1 A single vessel of the MEKO 360H1 variant was produced for the Nigerian Navy. Called , it is one of the largest vessels of that navy. MEKO 360H2 Six vessels were ordered and four vessels of a second variant, MEKO 360H2, were constructed for Argentina. They were locally named the . They are considered frigates and destroyers by different publications. The design is based on the concept of modular systems and is capab ...

Naval Ensign Of Nigeria (1960–1998)
A navy, naval force, military maritime fleet, war navy, 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 a 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bofors 40 Mm Automatic Gun L/70
The Bofors 40 mm Automatic Gun L/70, (Bofors 40 mm L/70, Bofors 40 mm/70, Bofors 40/70 and the like), is a multi-purpose autocannon developed by the Swedish arms manufacturer AB Bofors (today BAE Systems Bofors) during the second half of the 1940s as a modern replacement for their World War II-era Bofors 40 mm L/60 gun-design. It was initially intended as a dedicated anti-aircraft weapon, being sold as ''Bofors 40 mm Automatic A.A. Gun L/70'', but has since its conception been redeveloped into a dedicated multi-purpose weapon capable of firing both sabot projectiles and programmable ammunition. The 40 mm L/60 was introduced in 1932 and was a useful weapon for its era, being widely used among many forces and produced under license in several countries. The introduction of faster fighter-bombers and especially the widespread introduction of jet-powered aircraft in the post-war era severely limited its abilities. The L/70 was designed to improve both its opera ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Waterline
The waterline is the line where the hull of a ship meets the surface of the water. A waterline can also refer to any line on a ship's hull that is parallel to the water's surface when the ship is afloat in a level trimmed position. Hence, waterlines are a class of "ships lines" used to denote the shape of a hull in naval architecture lines plans. The load line (also known as Plimsoll line) is the waterline which indicates the legal limit to which a ship may be loaded for specific water types and temperatures in order to safely maintain buoyancy. For vessels with displacement hulls, the hull speed is defined by, among other things, the waterline length. In a sailing boat, the waterline length can change significantly as the boat heels, and can dynamically affect the speed of the boat. Aircraft In the aircraft design the term ''waterline'' designates a horizontal reference line used in alignment checks. The base line of the aircraft is designated as waterline 0 (zero). ...

Search And Rescue
Search and rescue (SAR) is the search for and provision of aid to people who are in distress or imminent danger. The general field of search and rescue includes many specialty sub-fields, typically determined by the type of terrain the search is conducted over. These include mountain rescue; ground search and rescue, including the use of search and rescue dogs (such as K9 units); urban search and rescue in cities; combat search and rescue on the battlefield and air-sea rescue over water. International Search and Rescue Advisory Group (INSARAG) is a UN organisation that promotes the exchange of information between national urban search and rescue organisations. The duty to render assistance is covered by Article 98 of the UNCLOS. Definitions There are many different definitions of search and rescue, depending on the agency involved and country in question. *Canadian Armed Forces and Canadian Coast Guard: "Search and Rescue comprises the search for, and provision of ai ...

Naval Gunfire Support
Naval gunfire support (NGFS), also known as naval surface fire support (NSFS), or shore bombardment, is the use of naval artillery to provide fire support for amphibious assault and other troops operating within their range. NGFS is one of several disciplines encompassed by the term ''naval fires''. Modern naval gunfire support is one of the three main components of amphibious warfare assault operations support, along with aircraft and ship-launched land-attack missiles. Shipborne guns have been used against shore defences since medieval naval warfare. Tactics Naval gunfire support is classified into two types: direct fire, where the ship has line of sight with the target (either visually or through the use of radar), and indirect fire, which, to be accurate, requires an artillery observer to adjust fire. When on the gun line, ships are particularly vulnerable to attack from aircraft coming from a landward direction and flying low to avoid radar detection, or from submari ...

Trafalgar 200
The Battle of Trafalgar was a naval engagement that took place on 21 October 1805 between the Royal Navy and a combined fleet of the French and Spanish navies during the War of the Third Coalition. As part of Napoleon's planned invasion of the United Kingdom, the French and Spanish fleets combined to take control of the English Channel and provide the Grande Armée safe passage. The allied fleet, under the command of French admiral Pierre-Charles Villeneuve, sailed from the port of Cádiz in the south of Spain on 18 October 1805. They encountered a British fleet under Lord Nelson, recently assembled to meet this threat, in the Atlantic Ocean along the southwest coast of Spain, off Cape Trafalgar. Nelson was outnumbered, with 27 British ships of the line to 33 Franco-Spanish ships, including the largest warship in either fleet, the Spanish '' Santísima Trinidad''. To address this imbalance, Nelson sailed his fleet directly at the allied battle line's flan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anti-submarine Warfare
Anti-submarine warfare (ASW, or in the older form A/S) is a branch of underwater warfare that uses surface warships, aircraft, submarines, or other platforms, to find, track, and deter, damage, or destroy enemy submarines. Such operations are typically carried out to protect friendly shipping and coastal facilities from submarine attacks and to overcome blockades. Successful ASW operations typically involve a combination of sensor and weapon technologies, along with effective deployment strategies and sufficiently trained personnel. Typically, sophisticated sonar equipment is used for first detecting, then classifying, locating, and tracking a target submarine. Sensors are therefore a key element of ASW. Common weapons for attacking submarines include torpedoes and naval mines, which can both be launched from an array of air, surface, and underwater platforms. ASW capabilities are often considered of significant strategic importance, particularly following provocative instanc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anti-aircraft Warfare
Anti-aircraft warfare (AAW) is the counter to aerial warfare and includes "all measures designed to nullify or reduce the effectiveness of hostile air action".AAP-6 It encompasses surface-based, subsurface (Submarine#Armament, submarine-launched), and air-based weapon systems, in addition to associated sensor systems, command and control arrangements, and passive measures (e.g. barrage balloons). It may be used to protect naval, army, ground, and air forces in any location. However, for most countries, the main effort has tended to be homeland defense. Missile defense, Missile defense is an extension of air defence, as are initiatives to adapt air defence to the task of intercepting any projectile in flight. Most modern anti-aircraft (AA) weapons systems are optimized for short-, medium-, or long-range air defence, although some systems may incorporate multiple weapons (such as both autocannons and surface-to-air missiles). 'Layered air defence' usually refers to multiple 't ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nigerian Navy
The Nigerian Navy (NN) is the Navy, naval branch of the Nigerian Armed Forces, Nigerian armed forces. With more than 70 warships, it is categorised as the fourth strongest navy in Africa (after South Africa, Egypt, Algeria and Morocco). It is considered well-trained and has participated in several peacekeeping missions. History The Nigerian Navy owes its origin to the Nigerian Marine. Formed in 1914 after the amalgamation of the then Northern Nigeria Protectorate, Northern and Southern Nigeria Protectorate, Southern Nigeria, the Nigerian Marine, as it became known after 1914, was a quasi-military organization. This force expanded to become the Southern Nigerian Marine in 1893. A Northern Nigeria equivalent was formed in 1900. The two Marines were merged in 1914. Responsibilities included administration of the ports and Harbor, harbours, dredging of channels, buoyage and lighting. It also operated ferry services, touring launches, and other small craft that plied the various cree ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
