60-550: Hughes Helicopters was a major manufacturer of military and civilian helicopters from the 1950s to the 1980s. The company began in 1947, as a unit of Hughes Aircraft , then was part of the Hughes Tool Company after 1955. It became the Hughes Helicopter Division, Summa Corporation in 1972, and was reformed as Hughes Helicopters, Inc. in 1981. However, throughout its history, the company

120-405: A corporate , although this term can also apply to cooperating companies and their subsidiaries with varying degrees of shared ownership. A parent company does not have to be the larger or "more powerful" entity; it is possible for the parent company to be smaller than a subsidiary, such as DanJaq , a closely held family company, which controls Eon Productions , the large corporation which manages

180-607: A Dakota and act as "beaters" to drive the guerillas into stop groups landed by the helicopters. During the Troubles , the Provisional Irish Republican Army (IRA) became adept at avoiding conventional, fixed roadblocks and patrols. To prevent predictable patterns, the patrols were deployed by helicopter, known as Eagle Patrols, and were then able to disrupt the IRA's ability to move personnel and arms. In

240-553: A cost-cutting measure some nations and services have been tempted to use what are essentially commercial helicopters for military purposes. For example, it has been reported that China is carrying out a rapid enlargement of its assault helicopter regiments with the civilian version of the Russian Mil Mi-17 . These helicopters without armour and electronic counter measures will function well enough for training exercises and photo opportunities but would be suicidal to deploy in

300-487: A definition that provides that "control" is "the capacity of an entity to dominate decision-making, directly or indirectly, in relation to the financial and operating policies of another entity so as to enable that other entity to operate with it in pursuing the objectives of the controlling entity". This definition was adapted in the Australian Corporations Act 2001 : s 50AA. Furthermore, it can be

360-586: A government-owned or state-owned enterprise . They are a common feature of modern business life, and most multinational corporations organize their operations in this way. Examples of holding companies are Berkshire Hathaway , Jefferies Financial Group , The Walt Disney Company , Warner Bros. Discovery , or Citigroup ; more focused companies include IBM , Xerox , and Microsoft . These, and others, organize their businesses into national and functional subsidiaries, often with multiple levels of subsidiaries. Subsidiaries are separate, distinct legal entities for

420-404: A joint arrangement (joint operation or joint venture) over which two or more parties have joint control (IFRS 11 para 4). Joint control is the contractually agreed sharing of control of an arrangement, which exists only when decisions about the relevant activities require the unanimous consent of the parties sharing control. The Companies Act 2006 contains two definitions: one of "subsidiary" and

480-432: A judgment against the parent if they can pierce the corporate veil and prove that the parent and subsidiary are mere alter egos of one another. Thus any copyrights, trademarks, and patents remain with the subsidiary until the parent shuts down the subsidiary. Ownership of a subsidiary is usually achieved by owning a majority of its shares . This gives the parent the necessary votes to elect their nominees as directors of

540-541: A large portion of the commercial market for Hughes. It would eventually become part of the Army inventory as a primary trainer ( TH-55 Osage ). In May 1965 , the company won the contract for a new observation helicopter for the U.S. Army , and produced the OH-6 Cayuse (Hughes Model 369). The OH-6 was later developed into the civilian Model 500 , variants of which remain in production to this day. In 1972 , Hughes sold

600-803: A stabilised mount along with multi-function lasers capable of acting as laser rangefinder and targeting designators for weapons systems. By nature of the mission, the observation helicopter's primary weapons are its sensor suite and communications equipment. Early observation helicopters were effective at calling for artillery fire and airstrikes . With modern sensor suites, they are also able to provide terminal guidance to anti-tank guided weapons, laser-guided bombs and other missiles and munitions fired by other armed aircraft. Observation helicopters may also be armed with combinations of gun and rocket pods and sometimes anti-tank guided missiles or air-to-air missiles , but in smaller quantities than larger attack helicopters. Primarily, these weapons were intended for

660-462: A subsidiary undertaking, if: The broader definition of "subsidiary undertaking" is applied to the accounting provisions of the Companies Act 2006, while the definition of "subsidiary" is used for general purposes. In Oceania , the accounting standards defined the circumstances in which one entity controls another. In doing so, they largely abandoned the legal control concepts in favour of

720-454: A weakness. Emplaced insurgents and local sympathisers may observe such facilities covertly and gather intelligence on the schedules and routes of patrols and convoys. With this intelligence the insurgents can time their operations to avoid the COIN forces or plan ambushes to engage them, depending on their own tactical situation. Helicopters return a measure of surprise and tactical flexibility to

780-452: Is a multi-purpose helicopter . A utility military helicopter can fill roles such as ground attack , air assault , military logistics , medical evacuation , command and control , and troop transport . While not essential to combat operations, helicopters give a substantial advantage to their operators by being a force multiplier . To maximise their impact, helicopters are utilised in a combined arms approach. High-intensity warfare

840-1002: Is a subsidiary/child company of the ultimate parent company, while a second-tier subsidiary is a subsidiary of a first-tier subsidiary: a "grandchild" of the main parent company. Consequently, a third-tier subsidiary is a subsidiary of a second-tier subsidiary—a "great-grandchild" of the main parent company. The ownership structure of the small British specialist company Ford Component Sales, which sells Ford components to specialist car manufacturers and OEM manufacturers, such as Morgan Motor Company and Caterham Cars , illustrates how multiple levels of subsidiaries are used in large corporations: The word "control" and its derivatives (subsidiary and parent) may have different meanings in different contexts. These concepts may have different meanings in various areas of law (e.g. corporate law , competition law , capital markets law ) or in accounting . For example, if Company A purchases shares in Company B, it

900-646: Is characterized by large arrays of conventional armed forces, including mass formations of tanks , with significant air defenses. Helicopter armament and tactics were changed to account for a less-permissive flight environment. Anti-tank missiles , such as the SS.11 and the Aérospatiale SS.12/AS.12 were developed and mounted on French military helicopters. In turn, the United States adapted its BGM-71 TOW for firing from helicopters and eventually developed

960-417: Is limited to the installed power and lift capability and the limits installed equipment places on useful payload. The most extensive armour is placed around the pilots, engines, transmission, and fuel tanks. Fuel lines, control cables and power to the tail rotor may also be shrouded by Kevlar armour. The most heavily armoured helicopters are attack, assault and special forces helicopters. In transport helicopters

1020-497: Is possible that the transaction is not subject to merger control (because Company A had been deemed to already control Company B before the share purchase, under competition law rules), but at the same time Company A may be required to start consolidating Company B into its financial statements under the relevant accounting rules (because it had been treated as a joint venture before the purchase for accounting purposes). Control can be direct (e.g., an ultimate parent company controls

1080-534: Is that personnel and cargo can be moved to and from locations without requiring a runway for takeoffs and landings. Cargo is carried either internally, or externally by slung load where the load is suspended from an attachment point underneath the aircraft. Personnel are primarily loaded and unloaded while the helicopter is on the ground. However, when the terrain restricts even helicopters from landing, personnel may also be picked up and dropped off using specialized devices, such as rescue hoists or special rope lines, while

1140-624: The AGM-114 Hellfire . Meanwhile, the Soviet Union adapted the 3M11 Falanga missile for firing from the Mil Mi-24 . In the air, attack helicopters armed with anti-tank missiles, and one or more unarmed, or lightly armed scout helicopters operate in concert. The scout helicopter, flying at low level in a nap-of-the-earth approach, attempts to both locate the enemy armoured columns and to map out approaches and ambush positions for

1200-674: The Bell UH-1 Iroquois (known as the "Huey") has given rise to a number of derivatives through stretching and re-engining, including the Bell AH-1 . Modern helicopters have introduced modular systems which allow the same airframe to be configured for different roles, for example the Augusta Westland AW101 "Merlin" in Royal Navy service can be rapidly configured for ASW or transport missions in hours. To at

1260-679: The Combat search and rescue (CSAR) mission. Some services use a version of their operational helicopters, usually in the light class, for pilot training. For example, the British have used the Aérospatiale Gazelle both in operations and as a trainer. Some services also have an ab initio phase in training that uses very basic helicopters. The Mexican Navy has acquired a number of the commercially available Robinson R22 and R44 helicopters for this purpose. A utility helicopter

1320-470: The James Bond franchise. Conversely, the parent may be larger than some or all of its subsidiaries (if it has more than one), as the relationship is defined by control of ownership shares, not the number of employees. The parent and the subsidiary do not necessarily have to operate in the same locations or operate the same businesses. Not only is it possible that they could conceivably be competitors in

1380-697: The Mil Mi-28 N, the Kamov Ka-52 , and the AH-64D Longbow , incorporate sensors and command and control systems to relieve the requirement for scout helicopters. To enhance the combat endurance of these missile-armed helicopters, transport helicopters were used to carry technicians, reloads and fuel to forward locations. Establishing these forward arming and refuel points (FARP) at pre-arranged locations and times allowed armed or attack helicopters to re-arm and refuel, often with their engines running and

1440-563: The aftermath of the American invasion of Iraq helicopters have been used as aerial supply trucks and troop transports to prevent exposure to ambushes set by the Iraqi insurgency . Due to the cost and complexity of training and support requirements, insurgent forces rarely have access to helicopters. The major Western European helicopter manufacturers are Leonardo S.p.A. (formerly AgustaWestland ) and Eurocopter Group . In North America,

1500-611: The licensed production of those companies products, whilst building up their own ability to design and manufacture helicopters through a process of workshare and technology transfer. In India, Hindustan Aeronautics Limited is the main helicopter manufacturer for the Indian Armed Forces . In the Soviet planned economic system, the Mil and Kamov OKBs were responsible only for the design of helicopters. A re-organisation of

1560-627: The 1960s, the development of the turboshaft engine and transistor technology changed the face of maritime helicopter aviation. The turboshaft engine allowed smaller helicopters, such as the Westland Wasp , to operate from smaller vessels than their reciprocating engine predecessors. The introduction of transistors allowed helicopters, such as the Sikorsky SH-3 Sea King , to be equipped with integral dunking sonar , radar and magnetic anomaly detection equipment. The result

1620-432: The British, Spanish, and Italian navies, the larger helicopters form the main anti-submarine strength of carrier air wings. When operating from shore bases, the helicopters are used as anti-submarine pickets to protect against hostile submarines loitering outside military ports and harbours; their endurance and payload providing advantages over smaller helicopters. Soviet maritime helicopters, operating from its cruisers, had

1680-706: The COIN commander. Patrols need not start and end in the same place (the main entrance of the local compound), nor do supply convoys need follow the same roads and highways. During the Rhodesian Bush War , the Rhodesian military developed and refined " Fireforce " tactics, using small flights of light helicopters, the helicopters would be equipped as gunships to directly attack insurgents with aerial gunfire and also as either an airborne command/observation post or troop transport. Once contact had been established against enemy guerillas paratroopers would be dropped by

1740-548: The LZ. The advantage of air assault over an airborne assault is the ability of the helicopters to continually resupply the force during the operation, as well as to transport the personnel and equipment to their previous location, or a follow-on location if the mission dictates. The first reconnaissance and observation aircraft were balloons, followed by light airplanes, such as the Taylorcraft L-2 and Fieseler Fi 156 . As

1800-719: The United States to rescue downed aircrews and injured personnel in remote areas of the China Burma India Theater , from April 1944 until the war's end. The use of helicopters for rescue during combat increased during the Korean War and the Algerian War . In the Vietnam War the USAF acquired Sikorsky S-61R (Jolly Green Giant) and Sikorsky CH-53 Sea Stallion (Super Jolly Green Giant) helicopters for

1860-612: The additional role of guidance of the cruisers' long range anti-shipping missiles. Maritime helicopters are navalised aircraft for operation from ships. This includes enhanced protection against salt water corrosion , protection against ingestion of water, and provision for forced ditching at sea. As helicopters came into military service, they were quickly pressed into service for search and rescue and medical evacuation . During World War II, Flettner Fl 282s were used in Germany for reconnaissance , and Sikorsky R-4s were used by

1920-462: The aircraft hovers overhead. Air assault is a military strategy that relies heavily on the use of transport helicopters. An air assault involves a customized assault force that is assembled on the pick-up zone and staged for sequential transport to a landing zone (LZ). The idea is to use the helicopters to transport and land a large number of troops and equipment in a relatively short amount of time, in order to assault and overwhelm an objective near

1980-456: The assault role in actual combat situations. The intention of China appears to be to retrofit these helicopters with locally produced electronics and armour when possible, freeing available funds to allow rapid creation of enough regiments to equip each of its Group Armies , allowing a widespread buildup of experience in helicopter operations. Attack helicopters are helicopters used in the anti-tank and close air support roles. The first of

2040-427: The attack helicopters. Late-model scout helicopters include laser designators to guide missiles fired from the attack helicopters. After finding a target, the scout helicopter can locate it and then direct the attack helicopter's missile where to fire. The attack helicopters have only to rise from cover briefly to fire their missiles before returning to a concealed location. Late-development of attack helicopters, such as

2100-477: The capability of the early helicopters was as plane guard - tasked with the recovery of pilots who had ditched near an aircraft carrier . As helicopter technology matured with increased payload and endurance , anti-submarine warfare (ASW) was added to the helicopter's repertoire. Initially, helicopters operated as weapons delivery systems, attacking with air-launched torpedoes and depth charges based on information provided by its parent and other warships. In

2160-423: The company. Two or more subsidiaries that either belong to the same parent company or having a same management being substantially controlled by same entity/group are called sister companies . The subsidiary will be required to follow the laws where it is headquartered and incorporated. It will also maintain its own executive leadership. The subsidiary can be a company (usually with limited liability ) and may be

2220-514: The counter-reconnaissance fight—to eliminate an enemy's reconnaissance assets—but they can also be used to provide limited direct fire support or close air support. Among the first practical uses of helicopters when the Sikorsky R-4 and R-5 became available to British and American forces was deployment from navy cruisers and battleships, at first supplementing and later replacing catapult-launched observation aircraft . Another niche within

2280-461: The crew compartment may or may not be fully armoured, a compromise being to give the passengers Kevlar lined seats but to leave the compartment for the most part unarmoured. Survivability is enhanced by redundancy and the placement of components to protect each other. For example, the Blackhawk family of helicopters uses two engines and can continue to fly on only one (under certain conditions),

2340-946: The engines are separated by the transmission and placed so that if attacked from any one flank, the engine on that flank acts to protect the transmission and the engine on the other side from damage. Aviation electronics, or avionics , such as communication radios and navigation aids are common on most military helicopters. Specialized avionics, such as electronic countermeasures and identification friend or foe systems, are military specific systems that can also be installed on military helicopters. Other payload or mission systems are installed either permanently or temporarily, based on specific mission requirements; optical and IR cameras for scout helicopters, dunking sonar and search radar for anti-submarine helicopters, extra radio transceivers and computers for helicopters used as airborne command posts . Armour, fire suppression, dynamic and electronics systems enhancements are invisible to casual inspection; as

2400-504: The first military helicopters became available, their ability to both maneuver and to remain in one location made them ideal for reconnaissance. Initially observation helicopters were limited to visual observation by the aircrew, and most helicopters featured rounded, well-glazed cockpits for maximum visibility. Over time, the human eye became supplemented by optical sensor systems. Today, these include low light level television and forward looking infrared cameras. Often, these are mounted in

2460-551: The first production model AH-64 rolled off the production line at the company's new Mesa, Arizona facility. That same year, the company was honored by the National Aeronautic Association with the prestigious Collier Trophy . The company also licensed Schweizer Aircraft to produce the Model 300C . In January 1984 , Hughes Helicopters, Inc. was sold to McDonnell Douglas by Summa Corporation , under

2520-453: The first-tier subsidiary directly) or indirect (e.g., an ultimate parent company controls second and lower tiers of subsidiaries indirectly, through first-tier subsidiaries). Recital 31 of Directive 2013/34/EU stipulates that control should be based on holding a majority of voting rights, but control may also exist where there are agreements with fellow shareholders or members. In certain circumstances, control may be effectively exercised where

2580-465: The helicopter industry in Russia created Russian Helicopters , a holding company to bring together Mil, Kamov, and other helicopter manufacturing and maintenance plants. Subsidiary A subsidiary , subsidiary company or daughter company is a company owned or controlled by another company, which is called the parent company or holding company , which has legal and financial control over

2640-555: The marketplace, but such arrangements happen frequently at the end of a hostile takeover or voluntary merger. Also, because a parent company and a subsidiary are separate entities, it is entirely possible for one of them to be involved in legal proceedings, bankruptcy, tax delinquency, indictment or under investigation while the other is not. In descriptions of larger corporate structures, the terms "first-tier subsidiary", "second-tier subsidiary", "third-tier subsidiary", etc. describe multiple levels of subsidiaries. A first-tier subsidiary

2700-451: The maximum size of the helicopters and the minimum size of the ships. Increasing miniaturisation of electronics, better engines and modern weapons now allow even the modern, destroyer-based, multi-role helicopter to operate nearly autonomously in the ASW, anti-shipping, transport, SAR and reconnaissance roles. Medium- and large-sized helicopters are operated from carriers and land bases. In

2760-775: The modern attack helicopters was the Vietnam era Bell AH-1 Cobra , which pioneered the now classic format of pilot and weapons officer seated in tandem in a narrow fuselage, chin mounted guns, and rockets and missiles mounted on stub wings. To enable them to find and identify their targets, some modern attack helicopters are equipped with very capable sensors such as a millimeter wave radar system. Transport helicopters are used for transporting personnel (troops) and cargo in support of military operations. In larger militaries, these helicopters are often purpose-built for military operations, but commercially available aircraft are also used. The benefit of using helicopters for these operations

2820-482: The other "subsidiary undertaking". According to s.1159 of the Act, a company is a "subsidiary" of another company, its "holding company", if that other company: The second definition is broader. According to s.1162 of the Companies Act 2006, an undertaking is a parent undertaking in relation to another undertaking, a subsidiary undertaking, if: An undertaking is also a parent undertaking in relation to another undertaking,

2880-471: The parent holds a minority or none of the shares in the subsidiary. According to Article 22 of the directive 2013/34/EU an undertaking is a parent if it: Additionally, control may arise when: Under the international accounting standards adopted by the EU a company is deemed to control another company only if it has all the following: A subsidiary can have only one parent; otherwise, the subsidiary is, in fact,

2940-594: The parent's efforts to streamline its focus and interest in real estate development . McDonnell Douglas paid $ 470 million for the company and made it a subsidiary . Hughes Helicopters was renamed McDonnell Douglas Helicopter Systems later in August 1984. Although the direct link with Hughes was broken, the helicopter designs created by Hughes Helicopters would continue to be produced by Boeing Rotorcraft Systems , MD Helicopters , and Schweizer RSG . Military helicopter Military helicopters play an integral part in

3000-430: The purposes of taxation , regulation and liability . For this reason, they differ from divisions which are businesses fully integrated within the main company, and not legally or otherwise distinct from it. In other words, a subsidiary can sue and be sued separately from its parent and its obligations will not normally be the obligations of its parent. However, creditors of an insolvent subsidiary may be able to obtain

3060-431: The rotors still turning, and to quickly return to the front lines. In counter-insurgency (COIN) warfare, the government force establishes its presence in permanent or temporary military bases from which to mount patrols and convoys. The government forces seek to deter the insurgent forces from operating, and to capture or kill those that do. The operation of forces from fixed bases linked by a fixed network of roads becomes

3120-605: The same time retain flexibility and limit costs, it is possible to fit an airframe for but not with a system, for example in the US Army's Boeing AH-64D Apache variants are all fitted to be able to take the Longbow radar system, but not enough sets have been bought to equip the whole force. The systems can be fitted to only those airframes that need it, or when finances allow the purchase of enough units. Most military helicopters are armoured to some extent; however, all equipment

3180-466: The sea, land and air operations of modern militaries. Generally manufacturers will develop airframes in different weight/size classes which can be adapted to different roles through the installation of mission specific equipment. To minimise development costs the basic airframes can be stretched and shortened, be updated with new engines and electronics and have the entire mechanical and flight systems mated to new fuselages to create new aircraft. For example,

3240-460: The subsidiary, and so exercise control. This gives rise to the common presumption that 50% plus one share is enough to create a subsidiary. There are, however, other ways that control can come about, and the exact rules both as to what control is needed, and how it is achieved, can be complex (see below). A subsidiary may itself have subsidiaries, and these, in turn, may have subsidiaries of their own. A parent and all its subsidiaries together are called

3300-491: The three primary manufacturers are Boeing ( Boeing Vertol and McDonnell Douglas ), Bell Helicopter and Sikorsky Aircraft . In Japan, the three main manufacturers of helicopters are the aviation arms of the Japanese conglomerates Mitsubishi , Kawasaki and Fuji Heavy Industries . These companies initially followed a business model based on forming strategic partnerships with foreign, usually American, companies with

3360-599: The tool division of Hughes Tool Company , and reconsolidated his remaining holdings as the Summa Corporation , which included Hughes' property and other businesses. The Aircraft Division became the Hughes Helicopter Division, Summa Corp. That same year, the US Army issued a request for proposals (RFP) for an Advanced Attack Helicopter (AAH). From an initial list of 5 manufacturers Hughes Aircraft's Toolco Aircraft Division (later Hughes Helicopters) and Bell were selected as finalists. In 1975 , Hughes' Model 77/ YAH-64

3420-543: Was an aircraft able to more quickly respond to submarine threats to the fleet without waiting for directions from fleet vessels. Today, maritime helicopters such as the Sikorksy SH-60 Seahawk and the Westland Lynx are designed to be operated from frigates , destroyers and similar size vessels. The desire to carry and operate two helicopters from frigate- and destroyer-sized vessels has affected

3480-656: Was commercially unsuccessful. In 1955 the company began building light helicopters when Howard Hughes split the helicopter production unit from the Hughes Aircraft Co., and reconstituted it with the Hughes Tool Co. as the Hughes Tool Co. Aircraft Division , with a focus on the production of light helicopters. The Hughes Model 269 was the company's first successful helicopter design. Built in 1956, and entering production in 1957, it served to capture

3540-698: Was informally known as "Hughes Helicopters". It was sold to McDonnell Douglas in 1984 and made a subsidiary under the name McDonnell Douglas Helicopter Systems , which was later renamed MD Helicopters when McDonnell Douglas merged with Boeing . In 1947, Howard Hughes redirected the Hughes Aircraft Company 's efforts from airplanes to helicopters. The effort began in earnest in 1948, when helicopter manufacturer Kellett Autogiro Corporation sold their latest design to Hughes for production. The XH-17 "Sky Crane" first flew in October 1952, but

3600-441: Was selected over Bell 's YAH-63 . First flight of a development prototype occurred in 1977 . Also in 1975, Hughes engineers at began concept development work of NOTAR . In 1981 , Summa's Hughes Helicopter Division was reconstituted as Hughes Helicopters, Inc. . By December, six AH-64A prototypes had been built and the Army had awarded a purchase contract to the company. Production would reach more than 1,100 by 2005. In 1983 ,
