Confused over a no. of Attack Helicopter Projects been undertaken by Indian Armed forces, i thought to open this thread to differentiate b/w the LCH, Rudra & Apache attack Helos that will serve the Indian armed forces in years to come.

Apache Longbow AH-64D:

Introduction

Boeing (AH64 D Apache Longbow) and Mil (Mi 28 Havoc) competed to supply 22 attack helicopters of 2.5t class to the IAF. The Mi 28 did not meet IAF requirements during flight trials. Boeing is currently the only contender in the field. The contract is estimated to be worth $550 million.

Procurement History

A $550 million-tender procure 22 attack helicopters to replace IAFs ageing Mi-25 and Mi-35 attack helicopter fleet was issued in 2008.

India scrapped the tender on March 25, 2009 because none of the three companies still in the fray met the qualitative requirements.

A fresh tender was floated in mid 2009 and seven companies were invited to bid. The contract, estimated to be worth $600 million, stipulates aircraft in the 2.5t-class and envisages an optional delivery of additional 22 helicopters.

Qualitative Requirements

The qualitative requirements are as follows

* Twin engine
* High maneuverability
* Anti armor capability
* All weather capability
* All terrain capability

The IAF wants these gunships to be highly-agile, have good armor protection and a 20mm caliber turret gun, as also be capable of firing 70mm rockets with a 1.2-km range and missiles with at least 7-km range.

The helicopters are likely to be equipped with an electronic warfare and self protection suite developed by EADS and India's Defense Avionics Research Establishment.

Contenders

Of the seven companies invited to bid, only one remains in the fray as detailed below.

* Boeing AH-64D Apache Longbow
* Eurocopter Tiger
* AgustaWestland AW129
* Bell AH-1Z SuperCobra
* Sikorsky UH-60 Blackhawk
* Mil Mi-28
* HAL's Light Combat Helicopter

Eurocopter reportedly opted out of the race because the Tiger is undergoing upgrades and will not be available for trials in mid 2010 as required by the IAF.

Bell opted out of the race because its helicopter is still undergoing evaluation by the US Marine Corp.

HAL's Light Combat Hircraft, which is still underdevelopment, first took to the air in 2010.
Agusta Westland pulled out due to technical reasons.

Sikorsky pulled out due to time constraints and procedural bottlenecks within their country.
Mil's Mi-28 did not make the cut during flight trials.

Boeing AH-64D Selected

India announced on Tuesday, October 25, 2011 that Boeing AH-64D had been selected to meet the IAF requirement.

An Indian Defense Ministry source said, “We decided not to choose the Mi-28 for technical reasons. Our experts believe that the Mi-28N did not meet the requirements of the tender on 20 positions, while the Apache showed better performance.”

In August 2012, TOI reported that India was poised to sign a $1.4 billion deal for the purchase of the 22 helicopters as also the supply of 812 AGM-114 L-3 Hellfire Longbow missiles, 542 AGM-114 R-3 Hellfire-II missiles, 245 Stinger Block I-92 H missiles and 12 AN/APG-78 fire-control radars.

Introduction

The 5.5-tonne twin engine LCH is a derivative of Dhruv ALH with tandem seating. The HAL developed LCH will supplement the 22 attack helicopters that India is seeking as part of an international tender.

At a Glance

The Light Combat Helicopter (LCH) is a derivative of Advanced Light Helicopter (ALH) Dhruv. It features tandem seating, instead of side by side as on the Dhruv, armor protection, and a glass cockpit.

Its Shakti engine, jointly developed by HAL and Turbomeca of France, has been optimized for high altitude operations.

Dimensions

Armament

It will be armed with a 20mm turret twin-barrel gun, cluster bombs, rocket pods as well as air-to-air and air-to-ground missiles.

It has a chin-mounted canon along with the helmet mounted sighting system, which gives the pilot the capability to look and fire at targets around the aircraft.

The DRDO is reported to be developing the HELINA missile, a Nag derivative with an extended range of 7 km, to augment the helicopter's air-to-ground capability.

Advanced Rotor Design


Dr. Prasad Sampath, general manager of HAL's Rotary Wing Research & Design Center, told the press during Aero India 2011 that the LCH was ‘probably the most agile design in the world because of its rotor'.

Avionics

Its advanced sensor suite, developed with the help of Israel, consists of CCD Camera, Forward looking infrared imaging technology and Laser range finder, facilitates target acquisition in all weather conditions and at night.

The EW suite has been procured from SAAB, South Africa.

The Helicopter would be fitted with a Data Link for network-centric operations facilitating the transfer of mission data to the other airborne platforms and ground stations operating in the network, thus facilitating the force multiplication.

Role

LCH is intended for use in air defense against slow moving aerial targets, destruction of enemy air defence operations, escort to special heliborne operations, support of combat search and rescue operations, anti-tank role and scout duties.

Designed for anti-tank and anti-infantry roles with a maximum speed of 275 kmph (148kt), it will also be capable of high-altitude warfare since its operational ceiling will be 16,000 to 18,000 feet (5,490m).

Orders

HAL has already bagged a firm order to deliver 65 LCH to the IAF and 114 to the Army, company sources told PTI in December 2009.

On April 5, 2011, Flight magazine reported that deliveries against the order will start in 2013-14.

Development Schedule

The first prototype of the Light Combat Helicopter was to make its maiden flight in March 2009. The landmark event was subsequently postponed to mid-August.

"We have completed the design. However, there was a problem with one of the vendors who was supposed to provide the tooling for the LCH, and so we have no choice but to push the first flight to August," said Ashok Baweja, HAL's chairman, during Aero India 2009.

The scheduled slipped further and the aircraft eventually flew for the first time on March 30. However, the flight, restricted to just a hover, was run up to the official first flight scheduled in April.

First Flight

First official flight test is scheduled for April 2010, though there will be several flight tests in the run up to the event.

"The first flight was perfect and we achieved all the intended objectives," said an HAL official who witnessed the flight on March 30.

First Official Flight

The LCH formally took to the skies in the presence of the Defence Secretary RK Singh, Vice Chief of Air Staff, Air Marshal PK Barbora, Chairman HAL, Ashok Nayak and senior officials of Defence ministry and the forces at the HAL airport in Bangalore on May 23.

Chief Test pilot Unni Pillai and Hari Nair put up a spectacular flying display of the LCH on its maiden flight.

Second Prototype

The second prototype LCH - TD2 - was displayed at Aero India 2011. It started flying end June 2011.

According to HAL Chairman and Managing Director Ashok Nayak, the second LCH is a "considerable improvement" over the first prototype as HAL and DRDO scientists have been able to achieve substantial weight reduction.

"Not only that, the human and weapons payload capacity of the rotorcraft had already been exceeded than the parameters mandated by the Indian Air Force (IAF)," he told India Strategic defence magazine in July 2011.

The two prototypes had flown 76 hours by July 2011.

Third Prototype

A third prototype/tech demonstrator TD-3 is under fabrication as on August 2011, and will soon join the test program.

Initial Operational Clearance

LCH’s initial operational clearance (IOC) was scheduled for December, 2011.

The LCH was begin its first off-base trials at sea-level in October 2011, followed by off-base hot weather and cold weather trials at high altitude in Ladakh.

Weapons trials will take place between the hot and cold weather trials.

On June 28, 2012, the Livefist blog reported that the LCH is set to undergo sea level trials at AF Station Tambaram starting June 29, 2012. The trials are planned to span 7 to 10 days.

Final Operational Clearance

HAL aims to finish flight testing by February 2013.

After achievement of IOC, the schedule for final operational clearance (FOC) will be formalized. After receipt of FOC, HAL will approach IAF for supply orders and the delivery schedule.

The IAF (primary customer) has confirmed a requirement of 65 units, while the Army has said it intends to order 114.

Service Induction

The helicopter is likely to be certified in 2013, and inducted into the two services by 2014-15.

Developmental Challenges

The LCH is currently reported to be 580 kg over its target weight. HAL is struggling to trim the weight in order to keep the aircraft in compliance with the QRs.

The first Technology Demonstrator, named TD-1, is reported to be 400 kg heavier than planned.

HAL hopes to progressively reduce weight with future technology demonstrators.

“We will find ways of cutting down TD-1 by 180-200 kg; TD-2, which will fly in mid-2010, will be another 100 kg lighter; and TD-3, which will be ready by end-2010, will shave off another 65-75 kg,” Managing Director of HAL’s Helicopter Complex, R Srinivasan, told Business Standard in September.

When it enters service, the LCH will still be 200 kg in excess, a concession the IAF is willing to make.

HAL Rudra:

The ‘Rudra’ ALH has been approved for induction as part of modernisation and capability development efforts by India. The ‘Rudra’ ALH is a fully loaded attack chopper equipped with a various guns, rocket pods, air-to-air and anti-tank guided missiles.

While the ‘Rudra’ ALH is derived from the ‘Dhruv’ ALH, requisite changes pertaining to the airframe have been made which lends more agility and speed to the chopper. The ‘Rudra’ ALH will be 5.5-tonne class twin-engine chopper with a host of advanced features such as Automatic Flight Control System, Integrated Dynamic System, Full Authority Digital Electronic Control and its ability to cruise at speeds of 250 kilometer per hour. This weaponized aerial platform will complement the combat capability of the Indian Army in a crucial battlefield scenario. ‘Rudra’ ALH can be used for dual role of attack chopper as well as for carrying soldiers or ammunition.

r1_zpse4062045.jpg

The ALH Mk.IV WSI ‘Rudra’ shown with its current weapon complement at Aero-India 2013. The weapons include the M621 20mm automatic cannon, Mistral Air/Air missiles, 30 mm gun and ammo and unguided 68mm rockets.


IAI_AERO-125X125The helicopter on display here at Aero-India 2013 displays the entire weapon mix currently configured for the platform. This armament is currently limited to a chin-mounted Nexter 20mm M621 cannon mounted onto a THL 20 turret, 70mm rockets in four pods and four MBDA Mistral short-range air/air missiles. The Helicopter will carry up to eight anti-tank missiles – the Helicopter NAG (HELINA) missiles are planned. These weapons have been selected for the helicopter as a typical ‘arranged marriage’, when both platform and missile were too young and premature do decide upon. While the ALH has grown up and matured, NAG still lags behind and the Indian Army will have to take a decision soon, if it continues to commit to HELINA or move to one of the alternatives currently awaiting decision – PARS 3LR from MBDA or Spike ER from Rafael.

The COMPAS stabilized multi-sensor payload from Elbit Systems provides the eyes for the helicopter’s weapons.

The cockpit represents an advanced glass-cockpit layout, with large area multiple MFDs and helmet displays. Mounted over the beek-like nose is the stabilized multi-sensor COMPASS payload, providing the crew the imagery necessary for reconnaissance and target acquisition. COMPASS, developed by Elbit Systems, incorporates daylight and thermal cameras with powerful zoom, and three different lasers – a rangefinder, target designator and IR laser pointer, assisting in covert air/ground coordination.

Saab’s Integrated defensive Aids System (IDAS-3) protects the Rudra from various types of anti-aircraft threats.

The helicopter is fitted with an integrated defensive aids system (IDAS-3) from SAAB, which delivered the system’s components while the aircraft integration was provided by HAL. IDAS-3 utilizes UV missile approach warning sensors, LWS-310 laser warning sensors and RWS-300 radar warning receivers and flare dispensers. Two units are clearly visible on the upper cockpit sides.

HAL's rotorcraft division chief P. Soundara Rajan said, "In this particular case it involved four major groups of systems and weapons, involving eight countries: Israel, France, Belgium, South Africa, Germany, Italy, USA and India. Nearly 23 km of cables had to be laid and hundreds of hours of flight and ground tests were carried out."

Rudra is equipped with Forward Looking Infra Red and Thermal Imaging Sights Interface, a 20 mm turret gun, 70 mm rocket pods, Anti-Tank Guided Missiles and Air-to-Air Missiles.

The version is equipped with SAAB supplied Integrated Defensive Aids Suite (IDAS) with Electronic Warfare self-protection which is fully integrated into the modern glass cockpit.

ALH-WSI was first flight tested with the new engine on 16 August 2007 and is currently undergoing integration trial for armament and electro-optical systems.

A final round of weapon firing trials is scheduled in September 2011, starting with its 20-mm turret gun, followed by trials of its 70mm rockets and MBDA Mistral air-to-air missiles in November.

We need to increase local content in dhruv.................acc to a 2010 report its only 10%!!

Apart from that its a fine machine


can anyone clarify imported content now??

Can you link that particular report here. Also pls specify which components are indeginous and which are foreign made.
 
. .
Now the real reason for rejection of mi-28n is simple in my opinion

1)Millimetre wave radar mast

apache-yes and fully operational
mi-28n-planned and not operational

Without this mast providing 360 degrees awareness,,,its very difficult for the helicopter to go for SEAD operations without escort

2)Ordnance carried

Apache- empty weight of only 5000 odd kg due to less use of metal and more of composites
max take off weight of about 10,000 kg

Mi-28n -empty weight itself 8600 kg due to extensive metal use
max takeoff weight of 10,000

S0 mi-28n has considerably less limit to carry stuff

3)ATGM

Apache----primary atgm is AGM-114 hellfire with range of 500m-8 km
main advantage is semi-active radar homing and millimetre wave seeker

Mi28n------Primary atgm is 9m120ataka v,also called as at-9 spiral 2,,,,,,,has a range of upto 8 km too
main disadvantage is SALCOSguidance
