HAL Light Combat Helicopter (India)
https://en.wikipedia.org/wiki/HAL_Li...bat_Helicopter The HAL Light Combat Helicopter (LCH) is an Indian multirole combat helicopter developed and manufactured by Indian aerospace manufacturer Hindustan Aeronautics Limited (HAL). It has been ordered for both the Indian Air Force and the Indian Army. The type is also intended to be sold upon the export market, since 2015, HAL has been seeking other customers for the LCH. The impetus for the development of the LCH came in the form of the Kargil War, a conflict fought between India and neighbouring Pakistan in 1999, which revealed the Indian armed forces to lack a suitable armed rotorcraft capable of operating unrestricted in the high-altitude theatre. Accordingly, both HAL and the Indian armed forces commenced explorative efforts towards the defining of a conceptual combat helicopter to perform in this role. During 2006, the company announced that it had launched a development programme to produce such a rotorcraft, referred to simply as the Light Combat Helicopter. Originally, the LCH was anticipated to attain initial operating capability (IOC) by December 2010, however, development of the type was protracted and subject to several delays, some of which having been attributed to suppliers. The LCH drew extensively on an earlier indigenous helicopter developed and manufactured by HAL, the Dhruv; using this rotorcraft as a starting point has been attributed as significantly reducing the cost of the programme. On 29 March 2010, the first LCH prototype performed its maiden flight. An extensive test programme, involving a total of four prototypes, was conducted. During the course of these tests, the LCH gained the distinction of being the first attack helicopter to land in Siachen, having repeatedly landed at several high altitude helipads, some of which being as high as 13,600 feet to 15,800 feet. During mid 2016, the LCH was recognised as having completed its performance trials, paving way for the certification of its basic configuration. On 26 August 2017, limited series production of the LCH was formally inaugurated. Origins During the late 1990s, India and neighbouring nation Pakistan engaged in a brief but intensely-fought conflict commonly known as the Kargil War. This war, in which various elements of the Indian military were deployed, revealed operational shortcomings and areas for improvement, particularly the requirement for an attack helicopter that would be suitable for use within the high altitude climates in which some combat operations were fought along the north-western border region. Accordingly, there was considerable interest in not only the acquisition of a suitable contemporary rotorcraft for the task (as well as to replace several aging types in Indian military service, such as the Cheetah and Chetak), but for such an aircraft to be domestically developed and manufactured in India as well. During early 2004, Indian aerospace manufacturer Hindustan Aeronautics Limited (HAL) declared that the company was in the midst of discussions with the Indian armed forces on the prospects for a potential light combat helicopter derivative of the company's existing Dhruv utility helicopter platform for the requirement. During late 2004, the Indian armed forces decided to curtail plans to order foreign-built attack helicopters in anticipation of a decision to formally select the tentative LCH.[7] During 2006, HAL publicly announced that it had embarked upon the development of such an attack helicopter, which it referred to as the Light Combat Helicopter (LCH). During late 2006, the Indian government decided to aid the fledgling programme via the issuing of external finance to support the design phase of the LCH's development, this was done as to aid the attack helicopter in conforming with the established requirements of the Indian Army and the Indian Air Force. The LCH is a derivative of the HAL Dhruv, which had been developed during the 1990s and inducted into the Indian Armed Forces during the 2000s. Basing the LCH on an existing helicopter is expected to greatly reduce the associated costs of the programme, which was estimated to be roughly ?376 crore (US$54.4 million) in 2010. By 2010, the Indian Air Force was reportedly set to acquire 65 LCHs while the Indian Army was to also procure 114 LCHs for its own purposes. Role Attack helicopter National origin India Manufacturer Hindustan Aeronautics Limited First flight 29 March 2010 Status In production Primary users Indian Army Indian Air Force Produced 2010–present Number built 4 Program cost ?376 crore (US$54 million) Unit cost US$20.2 million Developed from HAL Dhruv During November 2016, the Indian Ministry of Defense (MoD) authorised the purchase of an initial batch of 15 LCHs for the Indian Air Force (IAF) and the Indian Army Air Corps (AAC), referred to as being a limited series production order. By mid-2017, the AAC had placed combined orders for 114 LCHs, while the IAF had a total of 65 LCHs on order. During early 2017, it was reported that the LCH's initial operating capability (IOC) with the Indian armed forces was expected to occur by 2018. The AAC intended to deploy the indigenous LCH alongside the American-built Boeing AH-64 Apache attack helicopter. Achieving export sales for the LCH has been a stated priority of both HAL and the Indian government. During mid-2016, a spokesperson for the Indian Defence Ministry stated the ministry was in the progress of holding discussions with several unidentified African nations on the topic of the LCH.
