DTN News - Top Best Fifth Generation Fighter Aircraft Projects

Defense War News Updates: DTN News - Top Best Fifth Generation Fighter Aircraft Projects
Source: DTN News - - This article compiled by Roger Smith 
(NSI News Source Info) TORONTO, Canada - March 1, 2013:  The classification of similar products - be it fighters, computer systems or naval frigates - in generations is a well established practice and is generally accepted as a quick shortcut to define the broad characteristics and time frames of a given product category. However, the inherent rigidities, inflexibilities and oversimplifications of such practices cannot be ignored, in the fighter aircraft sector, in particular.

As an example, the generation sequence and headings used by Lockheed Martin for fighters are generally shared by the defence community and can be summarised as follows:

A fifth-generation jet fighter is a fighter aircraft classification used in the United States and elsewhere encompassing the most advanced generation of fighter aircraft as of 2013. Fifth-generation aircraft are designed to incorporate numerous technological advances over the fourth generation jet fighter. The exact characteristics of fifth generation jet fighters are controversial and vague, with Lockheed Martin defining them as having all-aspect stealth even when armed, Low Probability of Intercept Radar (LPIR), high-performance air frames, advanced avionics features, and highly integrated computer systems capable of networking with other elements within the theatre of war for situational awareness. The only currently combat-ready fifth-generation fighter, the Lockheed Martin F-22 Raptor, entered service with the U.S. Air Force in 2005

10. Advanced Medium Combat Aircraft (AMCA) India 



The Advanced Medium Combat Aircraft (AMCA), formerly known as the Medium Combat Aircraft (MCA), is a single-seat, twin-engine fifth-generation stealth multirole fighter being developed by India.

9. KAI KF-X  South Korea



The Korea Aerospace Industries KF-X is a South Korean program to develop an advanced multirole fighter for the Republic of Korea Air Force (ROKAF) and Indonesian Air Force (TNI-AU), spearheaded by South Korea with Indonesia as the primary partner. It is South Korea's second fighter development program following the FA-50.

8. Mitsubishi ATD-X Shinshin Japan



The Mitsubishi ATD-X Shinshin is a prototype fifth-generation jet fighter that uses advanced stealth technology. It is being developed by the Japanese Ministry of Defense Technical Research and Development Institute (TRDI) for research purposes. The main contractor of the project is Mitsubishi Heavy Industries. Many consider this aircraft to be Japan's first domestically made stealth fighter. ATD-X is an acronym meaning "Advanced Technology Demonstrator – X". The aircraft's Japanese name is Shinshin. The aircraft's first flight is scheduled for 2014.

7. Mikoyan LMFS Russia


This Aircraft is also going to be introduced in 2020, it is a single engine stealth fighter and is based on the canceled MiG 1.44. Russian Air Force is going to use this aircraft and the project success rate is estimated as 80%.

 6.  J-XX China


 This will be introduced in 2020 and will be used by Chinese Air Force. It is proposed to have a single engine stealth fighter and will be based on J-10B, JF-17 or may be on a totally new design.

5. Sukhoi/HAL FGFA Russia/India

The Sukhoi/HAL Fifth Generati on Fighter Aircraft (FGFA) is a fifth-generation fighter being developed by India and Russia. It is a derivative project from the PAK FA (T-50 is the prototype) being developed for the Indian Air Force. FGFA was the earlier designation for the Indian version, while the combined project is now called the Perspective Multi-Role Fighter (PMF).


The completed PMF will include a total of 43 improvements over the T-50, including stealth, supercruise, advanced sensors, networking and combat avionics.

Two separate prototypes will be developed, one by Russia and a separate one by India. According to HAL chairman A.K. Baweja (speaking shortly after the India-Russia Inter-Governmental Committee meeting on 18 September 2008), both the Russian and Indian versions of the aircraft will be single-seater. The first aircraft will begin testing in India in 2014, with introduction into service expected by 2022.

4. F-35 Lightening II (JSF)  U.S., U.K, Italy, Netherlands, Australia, Canada, Norway, Denmark,  Turkey, Israel, Singapore,  Japan


The Lockheed Martin F-35 Lightning II is a family of single-seat, single-engine, fifth generation multirole fighters under development to perform ground attack, reconnaissance, and air defense missions with stealth capability. The F-35 has three main models; the F-35A is a conventional takeoff and landing variant, the F-35B is a short take off and vertical-landing variant, and the F-35C is a carrier-based variant.



The F-35 is descended from the X-35, the product of the Joint Strike Fighter (JSF) program. JSF development is being principally funded by the United States. The partner nations are either NATO members or close U.S. allies. It is being designed and built by an aerospace industry team led by Lockheed Martin. The F-35 carried out its first flight on 15 December 2006.

The United States plans to buy a total of 2,443 aircraft to provide the bulk of its tactical airpower for the U.S. Air Force, Marine Corps and Navy over the coming decades. The United Kingdom, Italy, Netherlands, Australia, Canada, Norway, Denmark, and Turkey are part of the development program; Israel, Singapore and Japan may also equip their air services with the F-35.

3. Black Eagle J-20 China



The Chinese J-20 “Black Eagle” 5th generation fighter could be superior to the F-35 Lightning II, and even on a par with the F-22 Raptor with its range, radar-evading stealth capability, as well as with its firepower.

2. PAK-FA Russia

 The Sukhoi PAK FA is a twin-engine jet fighter being developed by Sukhoi for the Russian Air Force. The Sukhoi T-50 is the prototype for PAK FA. The PAK FA is one of only a handful of stealth jet programs globally.


The PAK FA, a fifth generation jet fighter, is intended to be the successor to the MiG-29 and Su-27 in the Russian inventory and serve as the basis of the Sukhoi/HAL FGFA being developed with India. The T-50 prototype performed its first flight 29 January 2010. By 31 August 2010, it had made 17 flights and by mid-November, 40 in total. The second T-50 was to start its flight test by the end of 2010, but this was delayed until March 2011.

The Russian Defence Ministry will purchase the first 10 evaluation example aircraft after 2012 and then 60 production standard aircraft after 2016. The first batch of fighters will be delivered with current technology engines. The PAK-FA is expected to have a service life of about 30–35 years.

1. F-22 Raptor USA

The Lockheed Martin/Boeing F-22 Raptor is a single-seat, twin-engine fifth-generation supermaneuverable fighter aircraft that uses stealth technology. It was designed primarily as an air superiority fighter, but has additional capabilities that include ground attack, electronic warfare, and signals intelligence roles. Lockheed Martin Aeronautics is the prime contractor and is responsible for the majority of the airframe, weapon systems and final assembly of the F-22. Program partner Boeing Defense, Space & Security provides the wings, aft fuselage, avionics integration, and training systems.



The aircraft was variously designated F-22 and F/A-22 during the years prior to formally entering USAF service in December 2005 as the F-22A. Despite a protracted and costly development period, the United States Air Force considers the F-22 a critical component of U.S. tactical air power, and claims that the aircraft is unmatched by any known or projected fighter. Lockheed Martin claims that the Raptor's combination of stealth, speed, agility, precision and situational awareness, combined with air-to-air and air-to-ground combat capabilities, makes it the best overall fighter in the world today. Air Chief Marshal Angus Houston, former Chief of the Australian Defence Force, said in 2004 that the "F-22 will be the most outstanding fighter plane ever built."

The high cost of the aircraft, a lack of clear air-to-air combat missions because of delays in the Russian and Chinese fifth-generation fighter programs, a U.S. ban on Raptor exports, and the ongoing development of the planned cheaper and more versatile F-35 resulted in calls to end F-22 production. In April 2009, the U.S. Department of Defense proposed to cease placing new orders, subject to Congressional approval, for a final procurement tally of 187 operational aircraft. The National Defense Authorization Act for Fiscal Year 2010 lacked funding for further F-22 production. The final F-22 rolled off the assembly line on 13 December 2011 during a ceremony at Dobbins Air Reserve Base.

DTN News - INDIA DEFENSE NEWS: Helicopter Makers Such As Boeing, Sikorsky Aircraft Corp, Bell Helicopter Eye Indian Military Deals

Defense War News Updates: DTN News - INDIA DEFENSE NEWS: Helicopter Makers Such As Boeing, Sikorsky Aircraft Corp, Bell Helicopter Eye Indian Military Deals
Source: DTN News - - This article compiled by Roger Smith from reliable sources Economic Times
(NSI News Source Info) TORONTO, Canada - March 5, 2012:  A raft of helicopter makers such as BoeingSikorsky Aircraft CorpBell HelicopterEurocopter andAgustaWestland are hovering over the civil market in India. But they are also eyeing a bigger prize: military deals. The Indian armed forces are upgrading their ageing fleet and that means big orders and big money, running into billions of dollars, for these companies. 
According to Reuters, Indian Navy plans to induct 50 light helicopters. First off the block is an order for 16 multi role helicopters. Indian Army has a joint requirement for about 400 light helicopters along with the Air Force. Some companies are upbeat about the recent contact to buy war planes worth $15 billion that the government awarded to France's Dassault Rafale. 

Mick Maurer, president of Sikorsky Military Systems, says the procurement process in India is getting better. "It is more rigorous and more transparent. We believe that suits us very well." Maurer says in the long term, Sikorsky sees a 3:1 ratio vis-a-vis the military and commercial sales in terms of the size of the market. But he says both are very complementary markets. Many of the machines can be used for commercial and quasi-defence activities. 

If the civil copter market in India has come alive, it is thanks to the armed forces. Foreign companies in the defence market are bound by what is called offset obligations. India's defence procurement policy rules that foreign companies require that win contracts of 300 crore or more must procure equipment worth at least 30% of the deal amount from local suppliers to boost the homegrown arms industry. 

The Indian military has also become smarter, according to foreign company executives. "Sometimes manufacturers give a special price on aircraft, but raise the price on the support side. India has become aware of this and now looks at the total lifecycle costs in deals," says Maurer. 

The upshot is that companies like Sikorsky and Eurocopter have partnered Indian counterparts to set up base in India. Sikorsky has formed two joint ventures with the Tatas to make helicopter cabins and aircraft components. Eurocopter, which formed an Indian unit in 2010, has tieups with the Mahindras, the Tatas and governmentowned Hindustan Aeronautics Limited. AgustaWestland, the helicopter unit of Finmeccanica SpA of Italy, has a joint venture with the Tatas called Indian Rotorcraft. 

All these companies plan to expand in India. Textron, the parent company of Bell Helicopter, has opened a new global technology centre in Bangalore with more than 400 engineers. Bell plans to expand the workforce there over the next year, says the company's India head, BS Singh Deo. An AgustaWestland spokesman says the company recently opened a new larger office in Delhi. Copter makers are also expanding the customer support network by establishing authorised service centres along with a posse of engineers and technicians. 

All this bodes well for the commercial market. The AgustaWestland spokesman says construction work is about to start on the Indian Rotorcraft's facility in Hyderabad , which will produce the company's eight-seat utility helicopter AW119. Sikorsky eventually plans to produce helicopters that are virtually "100% done here" . "We are already a local company," says Maurer.

DTN News - SPECIAL REPORT: Indian Indigenous ALH Dhruv Helicopter - Faces Several Up Heals, But Still Flying

Defense War News Updates: DTN News - SPECIAL REPORT: Indian Indigenous ALH Dhruv Helicopter - Faces Several Up Heals, But Still Flying
Source: DTN News - - This article compiled by Roger Smith from reliable sources
(NSI News Source Info) TORONTO, Canada - January 14, 2011: The Indian Army have inducted 40 more utility variant of the Dhruv advanced light helicopter (ALH) manufactured by Hindustan Aeronautics Ltd (HAL) from 2008.

The Helicopter Division of the government-owned Hindustan Aeronautics Limited (HAL) has developed the Dhruv (Pole Star) advanced light helicopter (ALH), a light (5.5t class) multi-role and multi-mission helicopter for army, air force, navy, coast guard and civil operations for both utility and attack roles by day and night.

The helicopter, which is built to FAR 29 specifications, entered series production in 2000. 18 Dhruv helicopters were delivered to Indian Defence Forces in 2000-2003, eight to the army, three to the navy, four to the air force and three to the coast guard. The army received its first three Dhruvs in March 2002. By June 2008, 76 helicopters had been delivered to the Indian army and air force with 159 more on order. The Indian Navy has decided not to place any further orders.

The fleet of the Indian Air Force Display Team, Sarang (Peacock in English) includes the Dhruv helicopters.

In June 2008, HAL received the first export order for the Dhruv - seven helicopters for the air force of Ecuador.

In August 2006, Indian Air Force and Coast Guard Dhruv helicopters were instrumental in rescue operations after devastating floods in India. Over 500 people were rescued.

In February 2007, the Dhruv was qualified for high-altitude / low-temperature operations in Kashmir and Jammu.

In August 2007, maiden flights took place of the Dhruv powered by the new Shakti engine and of the weaponised variant of the helicopter. And In September 2007, the Indian Army announced that the Dhruv was ready for deployment to the Siachen sector in the Himalayas. The helicopter was deployed to the high-altitude airbase at Manasbal (Srinagar) and, in October 2007, a Dhruv helicopter flew at a record altitude of 27,500ft in Siachen. The armed variant is scheduled for initial operating capability in December 2009.

The helicopter has a twin-engine configuration allowing continued flight virtually throughout the flight envelope. The advanced technologies incorporated in the Dhruv design include automatic flight control, anti-resonance vibration isolation system (ARI), full authority digital electronic control (FADEC), hingeless main rotor, bearingless tail rotor, and an automatic flight control system.

Hindustan Aeronautics Limited and Israel Aircraft Industries have an agreement to market the Dhruv helicopter worldwide. IAI has developed an integrated helicopter avionics suite for the Dhruv, which includes day-and-night observation, electronic warfare suite, observation and targeting, and a flexible weapons carrying system.

Weapons

The army and air force helicopters have stub wings fitted to carry up to eight anti-armour missiles, four air-to-air missiles or four rocket pods for 70mm and 68mm rockets.

In December 2006, Nexter Systems (formerly Giat) was awarded a contract for the installation of the THL 20 20mm gun turret on the first 20 Indian forces Dhruv helicopters. The turret is armed with the M621 low-recoil cannon and is combined with a helmet-mounted sight.

Weapon system integrated (WSI) versions for the Indian Army will be fitted with the Nag anti-tank missile, being developed by India's Defence Research and Development Organisation (DRDO). The Nag missile has imaging infrared guidance and a range of about 4km. The WSI variant will also have FLIR (forward-looking infrared), CCD (charge coupled device) camera and a target acquisition system with thermal sight and laser rangefinder.

The naval variant can carry two torpedoes or four anti-ship missiles.

Countermeasures

The Dhruv's countermeasures suite can include: radar and missile detectors, infrared jammer, chaff and flare dispensers.

Saab Avitronics was awarded a serial production contract in December 2008 for the integrated defensive aids suite (IDAS) self-protection systems for Indian armed forces Dhruv helicopters. IDAS has also been fitted on Rooivalk, NH90 and Super Lynx 300 helicopters.

Dhruv cabin

The 7.3m³ cabin accommodates several layouts. As a passenger helicopter the cabin accommodates 12 or 14 seats. A crew door and a rearward sliding door are installed on each side of the fuselage for the military helicopters. The cargo compartment at the rear of the cabin has a volume of 2.16m³. Clamshell doors at the rear of the cabin provide easy and fast access for loading and unloading cargo.

Configured as an air ambulance the helicopter can carry two stretcher patients and four survivors or medical attendants or four stretcher patients and two medical attendants.

Engines

The prototype helicopter is fitted with two Turbomeca TM 333-2C or 2B2 engines rated at 740kW take-off power. A more powerful engine for the Dhruv, the Shakti (which carries the French name Ardiden 1H) rated at 900kW is being developed under a cooperative agreement between HAL and Turbomeca and will be manufactured at Bangalore. First flight with the new engine took place in August 2007 and it was certified in 2008.

"The Dhruv is of conventional design and about two-thirds by weight of composite construction."

The helicopter is fitted with self-sealing crash-resistant tanks installed under the cabin floor. The fuel system includes cross feeding and fuel dumping systems. The maximum fuel capacity is 1,400l.

Helicopter landing gear

The air force and army helicopters are equipped with non-retractable metal skid landing gear. All variants of the helicopter are fitted with a tail skid to protect the tail rotor in tail-down landings.

FPT Industries, Portsmouth, UK, supplies the Kevlar flotation bags for the skid and wheeled variants of the helicopter. The helicopter can also be equipped with a liferaft.

Sarang Helicopter display team flying the HAL build Dhruv helicopters participated in the Farnborough Air Show in UK from 16 to 30 Jul 08. Farnborough Air Show in Britain is considered to be the one of the biggest Air Show in the world. It would be the first time that an IAF team is participating in the Air Show. The team had participated earlier in Weddington International Air Show and Royal International Air Tattoo to commemorate the 90th Anniversary of Royal Air Force. Sarang team is one among two such helicopter display teams in the world the other being the Blue Eagle team of UK.

In June 2008 the Indian Navy asked Hindustan Aeronautics Ltd (HAL) to improve the naval version of the advanced light helicopter (ALH) 'Dhruv' before more of the flying machines are inducted into the service. Though the Navy have asserted that it had not "written off" the helicopter as speculated, it wanted HAL to work on certain suggestions to make 'Dhruv' fulfill the requirements of the Navy.

By mid-2008 the Indian Navy has virtually written off the naval variant of the Dhruv advanced light helicopter (ALH), saying it had failed to meet basic operational requirements. The navy, which operated a fleet of six [or eight] ALHs, decided against placing further orders with the Hindustan Aeronautics Limited. Navy officials said that the ALH lacked the desired endurance for mission requirements. The navy is also not satisfied with the chopper’s rotor blade folding mechanism for storage on warships and its payload capacity. The requirement of Blade Folding with a width of 3.5 meters was not feasible due to the inherent design characteristics of the ALH hingeless Main Rotor Blade with an Integrated Dynamic System. The navy wanted a helicopter to spend 2 hours and 20 minutes on task (i.e. airborne with its task payload), and have an additional reserve of 20 minutes. The Dhruv is simply not capable of meeting this requirement, which is beyond the inherent payload capacity of any 5.5 ton class helicopter and can be met with difficulty by a 10-ton class helicopter. Originally the prototype was powered by navalised and corrosion-resistant twin Rolls-Royce CTS800 engines preferred by the Indian Navy. However, HAL has instead settled for the Ardiden/Shakti engine that was not navalised.

As of mid-2008 it was planned that the Air force would induct 38 indigenous Dhruv helicopters and 16 of its armed versions with a glass cockpit and new engines.

Nepal is receiving three. In a joint venture with Israel Aircraft Industries, the Dhruv is offered for export with a Lahav avionics package, featuring a glass cockpit and Doppler/GPS navigation.

Foreign sales

The Dhruv helicopters of the Ecuadorian Air Force.

The Dhruv has become the first major Indian weapons system to have secured large foreign sales. HAL hopes to sell 120 Dhruvs over the next eight years, and has been displaying the Dhruv at airshows, including Farnborough and Paris in order to market the Dhruv.

With a unit price at least 15% less than its rivals, Dhruv has elicited interest in many countries, mostly from Latin America, Africa, West Asia, South East Asia and the Pacific Rim nations. Air forces from around 35 countries have sent in their inquiries, , along with requests for demonstrations.

The first foreign orders for the Dhruv were placed by Nepal in early 2004, for 2 Dhruvs.Another Dhruv, a civilian version, was leased to the Israeli Defense Ministry in 2004

In June 2008, the government of Peru ordered two air ambulance Dhruvs for use by the Peruvian health services. Peru has also shown interest in the military version Dhruv.

HAL also secured an order from the Ecuadorian Air Force for seven Dhruvs. HAL has gained this order amidst strong competition from Elbit, Eurocopter and Kazan. HAL’s offer of $ 50.7 million for seven helicopters was about 32% lower than the second lowest bid from Elbit. Five helicopters will be delivered in February 2009, during the Aero India 2009. The remaining two helicopters will be delivered within six months Ecuadorian Army and Ecuadorian Navy have also expressed unofficial interest in purchasing the helicopter.

Dhruv also participated in a Chilean tender for eight to ten 5.5 tonne, twin engined new generation helicopter, but lost to theBell Helicopters Bell 412 amid allegations of arm-twisting by the US Government. The evaluation included flights at high altitudes, hot and desert conditions, ship deck landing, search and rescue at 12,500 feet (3,800 m) MSL at a temperature of 2°C as well as long distance ferry flights, clocking 107 flying hours.

On August 10, 2008 HAL chairman confirmed it had finalized a deal with Turkey to supply 3 Dhruvs for $20 million. Turkey is planning to buy as many as 17 helicopters in medical assistance role.

India is also reportedly planning to transfer several Dhruvs to Burma. This led to protests from Amnesty International, who pointed to the use of components sourced from European suppliers as a possible violation of the EU Arms Embargo of Burma. In a letter to the President of the EU Council of Ministers, Amnesty stated that it had evidence that India planned to transfer two Dhruvs (with European components) to Burma. These reports have been denied by the Indian Government.

HAL is negotiating with Bolivia for delivery of five Dhruvs and with Venezuela for seven of the choppers in transport roles, and in Europe. The Dhruv is also being offered to Malaysia. Indonesia is also evaluating Dhruv helicopters for the Indonesian Army.

Flight certification for Europe and North America is also being planned, in order to tap the large civilian market there.
