LIGHT COMBAT HELICOPTER 

LIGHT COMBAT HELICOPTER 

Source: The Indian Express

1.Context 

The indigenous Light Combat Helicopter (LCH), capable of destroying enemy air defence, conducting counter-insurgency strikes and much more, was formally inducted into the Indian Air Force (IAF) at the Jodhpur air base on Monday.

2.Key points

  • The fleet of four helicopters was inducted at a ceremony. The helicopter will be called "Prachand", which means Fierce.
  • The LCH is the only attack helicopter in the world which can land and take off at an altitude of 5, 000 meters with a considerable load of weapons and fuel, meeting the specific requirements laid out by the Indian Armed Forces.
  • Hindustan Aeronautics Ltd  (HAL) developed its unique features, importance as a strategic asset and the road it faces ahead.

3.The genesis of the Helicopter 

  • It was during the 1999 Kargil war that the need was first felt for a homegrown lightweight assault helicopter that could hold precision strikes in all Indian battlefield scenarios.
  • This meant a craft that could operate in very hot deserts and also in very cold high altitudes, in counter-insurgency scenarios to full-scale battle conditions.

4.Chetak and Cheetah 

  • India has been operating sub-3-ton category French-origin legacy helicopters, Chetak and Cheetah, made in India by the HAL. These single-engine machines were, primarily, utility helicopters.
  • Indian forces also operate the Lancer, an armed version of Cheetah.
  • In addition, the Indian Air Force currently operates the Russian-origin Mi-17 and its variants Mi-17 IV and Mi-17 V5, with a maximum take-off weight of 13 tonnes, which are to be phased out starting in 2028.
  • But the requirement was for a more agile, multi-role dedicated attack helicopter.
  • After the initial deliberations, the government sanctioned the LCH project in October 2006 and HAL was tasked to develop it.
  • The Government sanctioned the LCH project in October 2006 and HAL was tasked to develop it.
  • The HAL's Rotary Wing Research and Development Centre, which had already worked on the Advanced Light Helicopter (ALH) Dhruva and its weaponised version ALH Rudra, embarked on the project.

5.The Development of LCH

  • It has been designed as a twin-engine, dedicated combat helicopter of 5.8-ton class, thus categorised as light.
  • It features a narrow fuselage and tandem one behind the other configuration for pilot and co-pilot.
  • The Copilot is also the Weapon Systems Operator (WSO).
  • While LCH inherits many features of the ALH, it mainly differs in tandem cockpit configuration, making it sleeker.
  • It also has many more state-of-art systems that make it a dedicated attack helicopter.
  • In the LCH's journey towards clearance and induction by the IAF and the Army, extensive flight testing has been carried out on four Prototypes, also known as Technology Demonstrators (TDs).

6.Technology Demonstrator

  • The first Technology Demonstrator (TD) was completed in February 2010 and took its first flight on March 29 of the same year.
  • TD-2 prototype, completed around 2012, successfully passed the cold weather trials at high altitudes.
  • TD-3 and TD-4 prototypes, completed around 2014 and 2015, successfully tested other flight test requirements.

7.Flight testing 

  • The Flight testing was carried out at various altitudes, from sea level to the Siachen range, in extreme cold and hot weather conditions and desert regions.
  • During these tests, the integration of mission sensors such as an electro-optical system, helmet-mounted display system, solid-state data and video recorder and weapon systems such as turret guns, rockets and air-to-air missile systems was carried out.
  • Weapons firing trials were also completed.
  • The four prototypes have together undergone over 2, 000 flights with close to 1600 flight hours.

8.Clearance

  • Initial operational clearance came in 2017 for the IAF variant and 2019 for the Army variant.
  • In August 2020, the MoD added LCH to the items under the import embargo.
  • In November 2021, Prime Minister Narendra Modi symbolically handed over the LCH to the Indian Air Force, Paving the way for its final induction.
  • In March this year, the Cabinet Committee on Security (CCS) approved the procurements of 15 LCH Limited Series Production (LSP) 10 for IAF and five for Army at the cost of Rs 3, 887 crores along with infrastructure sanctions worth Rs 377 crores.

9.Features and Significance of the LCH

LCH has a maximum take-off weight of 5.8 tonnes, a maximum speed of 268 kilometres per hour, a range of 550 kilometres, an endurance of over three hours and a service ceiling of the maximum density altitude to which it can fly of 6.5 kilometres.
 
  • The helicopter uses radar-absorbing material to lower radar signatures and has a significantly crash-proof structure and landing gear.
  • A pressurised cabin offers protection from nuclear, biological and Chemical (NBC) contingencies.
  • The helicopter is equipped with a countermeasure dispensing system that protects it from enemy radars or infrared seekers of enemy missiles.
  • As far as weapons systems are concerned, a 20 mm turret gun, 70 mm rockets and air-to-air missile systems are onboard.
  • LCH is powered by two French-origin Shakti engines manufactured by the HAL.
  • With these features, the LCH has the capabilities of combat roles such as destruction of enemy air defence, counter-insurgency warfare, combat search and rescue, and anti-tank and counter-surface force operations.

10.The road ahead

  • According to HAL, there is a projected requirement of 160 LCHs 65 for IAF and 95 for the Indian Army.
  • After receiving a contract for the LSP in March, some units have already been delivered and the rest are at various stages of acceptance.
  • HAL has said that it has drawn a detailed masterplan for achieving the peak rate production capacity of 30 helicopters per year to produce the remaining 145 LCHs in eight years from the date of signing of the Series Production order.
  • The LCH was formally inducted into the Army on September 29 at Bangalore and into the IAF on Monday at Jodhpur.
    For export, the HAL has already obtained a no objection certificate from the Ministry of Defence for Countries like Malaysia, Thailand, Vietnam, Angola, Egypt, Indonesia, Ecuador and Nigeria.
