The requirement would be fulfilled through the Strategic Partnership (SP) model including an Indian and a foreign Original Equipment Manufacturer (OEM) under the Make in India initiative. According to a report in April 2022, the Expression of Interest (EoI) to OEMs and Strategic Partners were issued in February 2019. However,

5236-531: The rear doors. The twin 1000 shp Turbomeca TM333-2B2 turboshafts are mounted above the cabin and drive a four-blade composite main rotor. The main rotor can be manually folded; the blades are mounted between carbon-fibre-reinforced plates, the rotor head is constructed from fibre elastomers. In February 2004, US helicopter company Lord Corporation were awarded a contract to develop an active vibration control system (AVCS), which monitors onboard conditions and cancels out fuselage vibrations. The cockpit section of

5313-429: The same time a weight-reduction programme was initiated. However, further delays in development were caused when sanctions were implemented against India following a number of Pokhran-II nuclear tests in 1998 and India's continued refusal to sign the Comprehensive Nuclear-Test-Ban Treaty . As a result, the intended engine for the helicopter, the LHTEC T800 , was embargoed . The Turbomeca TM 333-2B2 turboshaft engine

5390-504: The then-Indian Vice President K R Narayanan in attendance. This was followed by a second prototype (Z-3183) on 18 April 1993, an Army/Air Force version (Z-3268), and a navalised prototype (IN.901) with Allied Signal CTS800 engines and a retractable tricycle undercarriage. Development problems arose due to changing military demands and a funding shortfall in the wake of the 1991 Indian economic crisis . Naval testing on board INS  Viraat and other ships started in March 1998, and around

5467-401: Was cleared for high-altitude flying in the Siachen Sector after six months of trials. In October 2007, a Dhruv Mk.3 flew to an altitude of 27,500 feet (8,400 m) ASL in Siachen. An Indian Army report in 2009 criticised the Dhruv's performance, stating: "The ALH was not able to fly above 5,000m, though the army's requirements stipulated an ability to fly up to 6,500m"; this has been blamed on

5544-573: Was developed as a result of Israel's need for adapting the Dassault Mirage III to the specific requirements of the Israeli Air Force. The Kfir entered service with the IAF in 1975, the first units being assigned to the 101st "First Fighter" Squadron . Over the following years, several other squadrons were also equipped with the new aircraft. The Kfir's first recorded combat action took place on 9 November 1977, during an Israeli air strike on

5621-503: Was initiated in May 1979 by the Indian Air Force and Indian Naval Air Arm . HAL were given a contract by the Indian government in 1984 to develop the helicopter; Germany's Messerschmitt-Bölkow-Blohm (MBB) were contracted in July 1984 as a design consultant and collaborative partner on the programme. Although originally scheduled to fly in 1989, the first prototype ALH (Z-3182) made its maiden flight on 20 August 1992 at Bangalore with

5698-523: Was praised. The Dhruv could carry more people from high-altitude helipads than the heavier Mi-17 , and land where the lighter Bell 407 could not. Total flight time during Operation Rahat and Operation Surya Hope was 630 hours, of which 550 hours were dedicated to SAR missions. In January 2014, the Geological Survey of India (GSI) inducted a Dhruv equipped with a heliborne geophysical survey system (HGSS). Costing ₹ 63 crore (US$ 8 million),

5775-490: Was reported that the Dhruv's Integrated Dynamic System (IDS), which combines several key rotor control functions into a single module carrying the engine's power to the rotors, was suffering from excessive wear, necessitating frequent replacement; as a consequence the cruising speed had been restricted to 250 km/h and high-altitude performance was lessened as well. HAL contracted Italian aerospace firm Avio for consultancy purposes and they subsequently replicated production of

5852-608: Was selected as a replacement; in addition, Turbomeca agreed to co-develop a more powerful engine with HAL, originally known as the Ardiden . Turbomeca also assisted in the development of the helicopter; stress analysis and studies of rotor dynamics were conducted in France. The first flight of Dhruv with the new engine variant, called the Shakti , took place on 16 August 2007. The HAL Rudra , earlier known as Dhruv-WSI ( Weapons Systems Integrated ),

5929-458: Was supposed to be done by the EAF due to the warranty period being expired, the company was willing to assist them to make sure that the Dhruvs were operational. Quito declined further assistance. Same in performance to the Mk.3 however, has additional equipment such as a cabin mountain MG, High Intensity Search Light and a loud hailer. It is armed with a 12.7 mm HMG. Has additional equipment such as
