The HAL Rudra (Devanagari: रुद्र, “The God Of The Tempest”) aka ALH-WSI is an armed version of HAL Dhruv. 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 has undergone 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.

Initial Operational Clearance (IOC) is expected by late 2012 with deliveries of the production helicopters starting on or before 2013.

As per the initial orders, close to 70 Rudras are to be supplied to Indian armed forces. “It has comfortably-exceeded the payload and performance requirements at 6 km height. It has integrated sensors, weapons and electronic warfare suite using an upgraded version of the glass cockpit used in the Mk-III. The cockpit avionics is a state-of-the-art technology when it comes to helicopters. The sensors include stabilised day and night cameras, Infra-Red imaging, as well as laser ranging and designation,” sources said.

HAL Rudra can carry self defence systems including radar & missile detectors, IR jammer, chaff & flare dispensers.


Unarmed roles

  • Heliborne assault
  • Logistic support
  • Reconnaissance
  • Air observation post
  • Casuality evacuation
  • Training

Armed roles

  • Anti-tank warfare (ATW)
  • Close air support
  • Anti-Submarine Warfare (ASW)
  • Anti-Surface Vessel (ASV)


Rudra, or ALH-WSI (Weapon Systems Integrated) has two main versions.

  1. Mark III
    This has Electronic Warfare, countermeasures, sensors and targeting systems installed, but does not feature weapons.[5][6]
  2. Mark IV
    This would have a French Nexter 20 mm turret gun, Belgian 70 mm rockets, and MBDA air to air and air to ground missiles, such as the anti-tank Helina missile.

All these systems have been tested individually.



The HAL Light Combat Helicopter (LCH) is a multirole combat helicopter being developed in India by Hindustan Aeronautics Limited (HAL) for use by the Indian Air Force and the Indian Army.

In 2006, HAL announced its plans to build a LCH. Funds for the design and development of the LCH to meet the requirements of the Indian Army and the Indian Air Force were sanctioned in October 2006.
The LCH is a derivative of the HAL Dhruv, which was inducted into the Indian armed forces. Using a successful and proven helicopter as the base platform is expected to conserve the project costs for the LCH, which is pegged at Indian Rupee ₹8.76 billion (US$190.1 million).
The LCH was expected to be ready for the Initial Operational Clearance (IOC) by December 2010 with the Final Operational Clearance (FOC) in 2011. However, the revised timeframes hold that the 5.5-tonne LCH should be ready for induction into IAF by 2012-2013.
The first prototype of LCH completed its first ground run on February 4.HAL has a firm order to deliver 65 LCH to the IAF and 114 to the Army.
HAL has performed the maiden flight of its indigenously designed and developed LCH. The first Technology Demonstrator (TD-1) of the LCH flew the 20 minute flight from HAL’s Helicopter Complex, Bangalore on 29 March 2010. This flight provided an opportunity to carry out low speed, low altitude checks on the systems on-board. The crew reported that the performance of the helicopter and systems was satisfactory.

The LCH incorporates stealth features and crash landing gear for survivability. The LCH will have a narrow fuselage, with two crew stations.

The LCH is being designed to fit into an anti-infantry and anti-armour role and will be able to operate at high altitudes (16,300 feet). HAL hopes to equip the Indian Air Force with about 65 gunships.[6] The helicopter is powered by the HAL/Turbomeca Shakti turboshaft engine. The helicopter will be equipped with helmet-mounted targeting systems, electronic warfare systems and advanced weapons systems.

In 2006, HAL selected the M621 cannon incorporated in a Nexter THL 20 turret for the gun armament of the helicopter, operated by a helmet mounted sight.[7][8] Three prototypes will be built. The second version will be fitted with weaponry before its test flight. The Indian Air Force will be provided with the third prototype for user trials.

The LCH is to have a glass cockpit with multifunction displays, a target acquisition and designation system with FLIR, Laser rangefinder and laser designator. Weapons will be aimed with a helmet mounted sight and there will be an electronic warfare suite with radar warning receiver, laser warning receiver and a missile approach warning system.

The helicopter is 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,facilitating force multiplication.

With these features, the LCH is expected to play a major role in air defence 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.

The two pilots in the LCH sit one behind the other, compared to side-by-side in the Dhruv. All the flight controls, the hydraulics and the fuel system had to be redesigned for the LCH. The LCH’s many stealth features also necessitated redesigning the fuselage.

Operational history
The LCH TD-1 made its first flight on March 29, 2010. The second flight took place on April 28, 2010 at 15:30 hrs. As per HAL Press release, over 20 Test flights have been conducted to check various flight parameters.The third test flight of the LCH was successfully made on 23 May 2010 and it fulfilled the desired parameters and also paves the way for further testing with weapons. As of 17 December 2010 TD-1 has logged 50 hours of flight. The second prototype which will be weaponized with more sub-systems will be unveiled at Aero India 2011 in February 2011. Two more prototypes are under construction to speed up the process of its induction into the Indian Air Force in the year 2012.
