F-15K Slam Eagle

F-15K Slam Eagle
Roundel of the Republic of Korea Air Force.svg


 


The F-15K Slam Eagle is a variant of the combat-proven F-15E Strike Eagle. Equipped with the latest technological upgrades, it is more capable, survivable, and maintainable than its predecessor, the F-15E, and is capable of long-range precision strike missions without escort, day or night, in any weather.


The F-15K Slam Eagle represents the technology of choice for the increasingly complex combat arena. It is a true multi-role aircraft that operates in the air-to-air, air-to-ground, and air-to-sea role. The F-15K is highly capable with an effective combination of brains and brawn.


In 2002, South Korea/the Republic of Korea ordered 40 F-15K worth $4.2 billion including a weapons package for its F-X program with deliveries beginning in 2005 and ending in August 2008. The F-15K Strike Eagle maiden flight occurred on March 3, 2005, in Saint Louis. Subsequently, the first F-15K for the Republic of Korea rolled out at Boeing's facility in Saint Louis, Missouri, on March 16, 2005.


The F-15K Slam Eagle was the first F-15E variant entitled to carry up to 12 JDAM/Mk-82 500 pounds bombs on the aircraft's conformal fuel tanks stations. The armament options of the F-15K also highlights Harpoon Block II, SLAM ER and AIM-9X missiles.



General Characteristics:


Length: 63.8 ft (19.45 m)


Height: 18.5 ft (5.64 m)


Wingspan: 42.8 ft (13.05 m)


Maximum gross takeoff weight and payload: 81,000 lbs (metric) and 23,000 lbs (metric)


Maximum combat radius without refueling: More than 1,000 nm (1,800 km)


Power - F-15K Next Fighter I Program: Two GE F110 turbofan engines, 29,000 lb (131 kN) thrust class
Power - F-15K Next Fighter II Program: Two Pratt & Whitney F-100-PW-229 EEP engines (29,100 lb (metric) thrust class)


Payload: A mix of air-to-air weaponry: 20mm cannon; AIM-120, AIM-9, AIM-7, and AGM-130 missiles
A mix of air-to-ground ordnance, including precision-guided munitions


The continuing success of the F-15K Slam Eagle is the result of a blend of speed, power, and agility – a combination that makes the aircraft the ultimate multi-role strike fighter. It is agile and highly capable in the dogfight role, precise and survivable in the strike role.



The Brains


A state-of-the-art cockpit and advanced avionics make the F-15K Slam Eagle and its aircrew as smart as they are capable. Combined with the Joint Helmet Mounted Cueing System (JHMCS), the F-15K provides increased situational awareness and enhanced air-to-air and self-defense capabilities.


•The F-15K’s AN/APG-63 radar incorporates all air-to-air and air-to-ground modes of the APG-70 and adds Ground Moving Target Track, sea surface search and high resolution capability.

Akash Air Defence system



Akash Air Defence system






Akash uses state of the art integral ramjet rocket propulsion system to give a low-volume, low-weight (700 kg launch weight) missile configuration, and has a low reaction time - from detection to missile launch - of 15 seconds allowing the missile to carry a heavier 60 kg fragmentation warhead triggered by proximity fuse. 



Theoretically, a “ripple” of two Akash missiles has a 99 per cent chance of shooting down a modern fighter aircraft.

It reaches a speed of Mach 1.5 in 4.5 seconds Mach. 2.8-3.5 at 20g in 30 seconds after ramjet motor is ignited. Its range (for most effective performance) varies 27-30 kilometres. 

5.6 m long sleek missile has a launch weight of 700 kg and can carry 60 kg of warhead and the radar is capable of tracking 64 targets and guide upto 12 missiles simultaneously in a fully autonomous mode of operation.

The Akash is to bepurchased by the Indian air defence command and is for sale to customers abroad.

successfully tested it more than 45 times the DRDO is confident that Akash will be effective against low-flying missiles, aircraft and unmanned aerial vehicles.

Unlike the Patriot, can be launched from static or mobile platforms, including a battle tank. 

What makes it superior to Patriot, apart from the mobility of its platform, is that it has thrust during the entire course of its 35-second flight. Patriot has thrust only for 12 seconds, after which the missile coasts, thus making it less accurate than Akash. 



One Akash battery is composed of three tracked vehicles (tracks, like those on a battle tank), each of which would have four missiles, plus a vehicle carrying the Rajendra multifunction phased array radar. The Air Force version is on wheeled vehicles.

The missile can be deployed either in autonomous mode or group mode. In the autonomous mode, it will have a single battery functioning independently. For surveillance, it would need an additional two-dimensional radar. In this mode, it can be used for defending moving columns or singular installations. A single battery can simultaneously engage four targets, and against each target a maximum of three missiles can be fired, thus increasing the hit probability.

In group mode, there would be a number of batteries, deployed over a wide area. The batteries would be linked to a group control centre (GCC). The Rajendra three-dimensional radar, indegenously developed by the DRDO (defence Research & Development Organisation) would provide a single integrated air picture to the group control centre, telling it not only the distance at which the enemy plane has been located but also its altitude. One GCC can command and control a maximum of eight Akash batteries at the same time. One GCC can also receive radar surveillance information from other sources, and be linked to higher echelons of air defence. Once the target, either an enemy aircraft or a missile, is detected the missile would align to the radar beams and virtually travel on those beams (guided by onboard precision-homing system) towards the target at three-and-a-half times the speed of sound.

The DRDO is reportedly toying with the idea of developing an integrated missile shield, which would be able to cover an area of at least 200 sq. km in the next five to six years. Akash, or the technologies developed for Akash, would be at the heart of the system. Its radars could be placed on a civil aircraft, much like an AWACS system, to provide early warning of incoming missiles.Current development include a possible increase in speed, maximum altitude and range.

The Akash, at 0.26 million $, is cheaper than Patriot, and with Bharat Dynamics willing to manufacture it, there should not be a problem of service support. something which the Americans, given their history of imposing sanctions, may not be able to guarantee.



The Army's radar and launchers are based on the T-72 '' chassis'' to accompany the Army's fast moving armoured formations.



While Air Force versions use a combination of tracked and wheeled vehicle.




India eyes 'Patriot missile'

India could be poised to sign a multi billion dollar arms deal with the United States to purchase patriot missiles. Before Prime Minister Manmohan Singh's meeting with US President Barack Obama, the Indian Army has requested for a briefing of the Patriot-3 Anti-Missile System.



India's air defence systems will include Akash SAM, S-300 , SPYDER, Barak-8, AAD/PAD and hopefully PAC-3 providing a very potent list of Air Defence systems.

KALI (Kilo Ampere Linear Injector) India's secret super-weapon

The KALI (Kilo Ampere Linear Injector) is a linear electron accelerator being developed in India, by the Defence Research Development Organization (DRDO) and the Bhabha Atomic Research Centre (BARC).


The KALI is not a laser weapon as commonly believed. It emits powerful pulses of electrons (Relativistic Electron Beams- REB). Other components in the machine down the line convert the electron energy into EM Radiation, which can be adjusted to x-ray (as Flash X-Rays) or microwave (High Power Microwave) frequencies.


This has fueled hopes that the KALI could, one day be used in a High-Power Microwave gun, which could destroy incoming missiles and aircraft through soft-kill (destroying the electronic circuitry on the missile). However, weaponising such a system has many obstacles to overcome.
The KALI project was first mooted in 1985 by the then Director of the BARC, Dr. R. Chidambaram. Work on the Project began in 1989, being developed by the Accelerators & Pulse Power Division of the BARC. (Dr. Chidambaram was also the Scientific advisor the Prime Minister, and the Chairman of the Atomic Energy Commission). DRDO is also involved with this project. It was initially developed for industrial applications, although defence applications became clearer later.
The first accelerators had a power of ~0.4GW, which increased as later versions were developed. These were the KALI 80, KALI 200, KALI 1000, KALI 5000 and KALI 10000.The KALI-5000 was commissioned for use in late 2004.
The KALI series of accelerators are described as "Single Shot Pulsed Gigawatt Electron Accelerators". They are single shot devices, using water filled capacitors to build the charge energy. The discharge is in the range of 1GW. Initially starting with 0.4GW power, present accelerators are able to reach 40GW. Pulse time is about 60 ns.
The Microwave radiations emitted by the KALI-5000 are in the 3-5 GHz Range
The KALI-5000 is a pulsed accelerator of 1 MeV electron energy, 50-100 ns pulse time, 40kA Current and 40 GW Power level. The system is quite bulky as well, with the KALI-5000 weighing 10 tons, and the KALI-10000, weighing 26 tons. They are also very power hungry, and require a cooling tank of 12,000 liters of oil. Recharging time is also too long to make it a viable weapon in its present form.
he microwave-producing version of Kali has also been used by the DRDO scientists for testing the vulnerability of the electronic systems of the Light Combat Aircraft (LCA), which was then under development.


The KALI's potential for a military role as a beam weapon has made it, in the eyes of the people, "India's Star Wars". However, weaponisation of the KALI will take some time. The system is still under development, and efforts are being made to make it more compact, as well as improve its recharge time, which, at the present, makes it only a single use system.
There are also issues of creating a complete system, which would require development of many more components. There have also been reports of placing the weaponized KALI in an Il-76 aircraft as an airborne defence system. There is also speculation of using the KALI as an Anti-satellite weapon and as a space-based weapon system, although it is unlikely that they would be implemented, given India's stance on those issues.
If weaponized, it is quite likely that KALI would be integrated into India's fledgling Ballistic Missile Defense program.

India’s Light Combat Helicopter to fly in December

Light Combat Helicopter



The stage is set for the first prototype (LCH TD-1) flight of the Indian Light Combat Helicopter (LCH), scheduled to take place next month. The TD-1 will be an unweaponised platform, and the test-flight schedule for this prototype will only be towards validating principle airframe, aerodynamics, maneoverability and airworthiness parameters. Weapons integration tests will only take place with the second prototype, TD-2, that is scheduled for a first flight sometime later in 2010.HAL launched the LCH project in 2006 and developed the prototype at a cost of Rs.3.8 billion (Rs.380 crore).


Light Combat Helicopter mock up












A prototype of the light combat helicopter (LCH), designed and developed by the state-run Hindustan Aeronautics Ltd (HAL), is set for its maiden flight soon, a top company official said Friday.
“The prototype LCH is getting ready for a maiden test flight in the coming weeks. We are waiting for the final checks to be completed to commence flight trials,” HAL chairman and managing director Ashok Nayak told reporters here.
The 5.5-tonne LCH, a derivative of HAL’s advanced light helicopter (ALH) Dhruv, will be rolled out for anti-armour and anti-infantry roles by the Indian Air Force (IAF) and the Indian Army respectively.
Though the LCH was to take-off by August, HAL announced in September that the first flight would take place by this year-end or early January, as its overall weight had to be reduced by about 20 percent (580) kg.
“We have overcome the weight problem. The target weight will be achieved for a successful test flight,” a HAL copter division official told IANS later.
HAL launched the LCH project in 2006 and developed the prototype at a cost of Rs.3.8 billion (Rs.380 crore).
LCH is expected to get the initial operational clearance (IOC) by December 2010 and the final operational clearance (FOC) in 2011 for induction into the IAF by 2012-2013.
On the joint venture with Russian aerospace major (Irkut Corporation) for the multi-role transport aircraft (MRTA), Nayak hoped an agreement to that effect would be signed during the visit of Prime Minister Manmohan Singh to Moscow in early December.
“We hope the deal will take place this time so that we can jointly take up design and development of the MRTA for military and civilian use,” Nayak said at a function to mark 25 years of collaboration with the US-based technology major Honeywell International in manufacturing turboprop engine (TPE-331-5).
HAL plans to manufacture the 14-seater Saras aircraft, designed and developed by the state-run National Aerospace Laboratories (NAL) of the Council for Scientific and Industrial Research (CSIR) here.
“We plan to make 30-35 multi-role light transport aircraft primarily for the civilian market,” Nayak added.
In view of the huge order book valued at Rs.60,000 crore (Rs.600 billion) and some big-ticket projects in offing, HAL plans to invest Rs.25,000 crore over the next 10 years for expanding its infrastructure and other facilities across the country.

+ A modified Su-30MKI is being used to carry BrahMos cruise missiles with range 300 km.

+ Novator K-100 (Range-possibly 300–400 km )missile was designed to shoot down AWACS and other C4ISTAR aircraft whilst keeping the launch platform out of range of any fighters that might be protecting the target.

+N011M can function in air-to-air and air-to-land/sea mode simultaneously while being tied into a high-precision laser-inertial or GPS navigation system.






+Su-30MKI aerodynamic configuration is an unstable longitudinal triplane. The canard increases the aircraft lifting ability and deflects automatically to allow high angle-of-attack (AoA) flights allowing it to perform Pugachev's Cobra. The integral aerodynamic configuration combined with thrust vectoring results in extremely capable maneuverability, taking off and landing characteristics. This high agility allows rapid deployment of weapons in any direction as desired by the crew. The canard notably assists in controlling the aircraft at large angles-of-attack and bringing it to a level flight condition


Latest developments 

UAC together with HAL has been developing fifth generation fighter features such as 
internal weapons carriage and radar absorbent material for IAF Su-30MKIs by modifying their airframes to make them stealthy, converting the existing ‘Bars’ into an Active Phased Array Radar, enhancing the situational awareness by incorporating active electronically scanned transmit/receive arrays on the aircraft’s wings and pumping up the defensive-aids suite by installing a combined radar/laser warning system and a missile approach warning system.






JF-17 Thunder 










National origin   
   People's Republic
 of China

 Pakistan




JF-17 Thunder is a light-weight multi-role combat aircraft jointly developed by theChengdu Aircraft Industries Corporation (CAC) of China and the Pakistan Aeronautical Complex (PAC) of Pakistan. The "JF" and "FC" designations stand for "Joint Fighter" (Pakistan) and "Fighter China" (China) respectively.
Originally designed to be a small and capable lightweight fighter powered by a single engine to reduce costs, the JF-17 was supposed to be a simple and inexpensive solution for replacing large fleets of obsolete types in the air forces of developing countries. The JF-17 evolved into a more advanced fighter during the later stages of development with revised terms of reference by the Pakistan Air Force and the incorporation of more modern features and technologies



Crew: 1

Unit cost: US$ 15 million (estimated)

Max takeoff weight: 12,700 kg

Powerplant: 1× Klimov RD-93 turbofan

Maximum Speed : Mach 1.8

Radar: Italian Grifo S-7 ?

UNIQUE FEATURES 

+Ra'ad ALCM is planned to be integrated with and launched from JF-17.

+The EW suite is also linked to a missile approach warning (MAW) system to help it defend against radar-guided missiles.

+NRIET KLJ-7 radar's multiple modes allow surveillance and simultaneous engagement of multiple air, ground and sea targets, of which a total of 40 can be managed. Using the track-while-scan (TWS) mode, the radar can track up to 10 targets at beyond visual range (BVR) and engage 2 of them simultaneously with radar homing air-to-air missiles. The operation range for targets with a radar cross-section (RCS) of 5 m2 is stated to be ≥105 km in look-up mode and ≥85 km in look-down mode.

Latest developments 

Remaining production aircraft may also be equipped with European avionics, radars and weaponry. Pakistan had begun negotiations with British and Italian defence firms over potential avionics and radars for JF-17 during initial development. Some of the radar options for JF-17 are the Italian Galileo Avionica Grifo S7 and the French Thomson-CSF RC400 (a variant of the RDY-2), along with the MBDA MICA IR/RF short/medium range air-to-air missiles. The Vixen 500E AESA radar has also been offered to the PAF for installation on the JF-17 by the British company SELEX, but the PAF may be looking for a more advanced AESA radar





- please correct me if I am wrong with Specifications



Conclusion
