The HAL Dhruv is a utility helicopter designed and developed by Hindustan Aeronautics Limited (HAL) in November 1984. The helicopter first flew in 1992; its development was prolonged due to multiple factors including the Indian Army's requirement for design changes, budget restrictions, and sanctions placed on India following the 1998 Pokhran-II nuclear tests. The name comes from a Sanskrit origin word dhruv which means unshakeable or firm.[5]
Dhruv entered service in 2002. It is designed to meet the requirement of both military and civil operators, with military variants of the helicopter being developed for the Indian Armed Forces, while a variant for civilian/commercial use has also been developed. Military versions in production include transport, utility, reconnaissance and medical evacuation variants.
As of January 2024, more than 400 Dhruvs had been produced for domestic and export markets logging more than 340,000 flying hours.[2][6]
HAL Dhruv on board INS Vikrant during her sea trials
The Advanced Light Helicopter (ALH) program for an indigenous 5-ton multirole helicopter was initiated in May 1979 by the Indian Air Force and Indian Naval Air Arm.[7] HAL were given a contract by the Indian government in 1984 to develop the helicopter;[7][8] Germany's Messerschmitt-Bölkow-Blohm (MBB) were contracted in July 1984 as a design consultant and collaborative partner on the programme.[9][10] Although originally scheduled to fly in 1989, the first prototype ALH (Z-3182) made its maiden flight on 20 August 1992 at Bangalore with the then-Indian Vice President K R Narayanan in attendance.[11] 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.[12] Development problems arose due to changing military demands and a funding shortfall in the wake of the 1991 Indian economic crisis.[7]
Naval testing on board INS Viraat and other ships started in March 1998, and around the same time a weight-reduction programme was initiated.[13] 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.[13][14] The Turbomeca TM 333-2B2 turboshaft engine was selected as a replacement; in addition, Turbomeca agreed to co-develop a more powerful engine with HAL, originally known as the Ardiden.[15] Turbomeca also assisted in the development of the helicopter; stress analysis and studies of rotor dynamics were conducted in France.[16] The first flight of Dhruv with the new engine variant, called the Shakti, took place on 16 August 2007.[17][18]
The HAL Rudra, earlier known as Dhruv-WSI (Weapons Systems Integrated), is an attack variant designed for the Indian Army.[19] Development was sanctioned in December 1998[20] and the prototype first flew on 16 August 2007; it is to be armed with both anti-tank and anti-aircraft missiles, and a 20-mm turret-mounted cannon.[21] The Dhruv-WSI is to be capable of conducting combat air support (CAS) and anti-submarine warfare (ASW) roles as well.[22] In addition to the Dhruv-WSI, HAL is also developing the light combat helicopter (LCH) based on the Dhruv for the Indian Armed Forces. It is fitted with stub wings for carrying up to eight anti-armour missiles, four air-to-air missiles, or four pods loaded with either 70 mm or 68 mm rockets. The LCH will also have forward-looking infrared (FLIR), a charge-coupled device (CCD) camera, and a target acquisition system with laser rangefinder and thermal vision.[23]
A Dhruv of the Indian Army
In 2005, following a crash landing of a Dhruv, the entire fleet was grounded when it was discovered to have been caused by excessive vibration of the tail rotor. Following a redesign which incorporated new materials in addition to changes in design methodology, the Dhruv undertook recertification and returned to service shortly after March 2006.[24][25] In April 2007, a report published by the Indian Committee of Defence noted the Dhruv as one of four "focus areas" identified as having high export potential.[26] In January 2011, HAL and partner Israel Aerospace Industries (IAI) announced that they were jointly developing the Dhruv to operate as an unmanned maritime helicopter, stating customer interest in such a feature.[27]
The first five production Dhruv Mk III, powered by the more powerful Shakti-1H engine, were delivered to the Leh-based 205 Aviation Squadron on 7 February 2011 during a ceremony at HAL's Helicopter Division.[28] In July 2011, India's Directorate General of Civil Aviation certified a Dhruv simulator developed by HAL and Canadian developer CAE Inc; the simulator is easily modifiable to simulate different variants of the Dhruv and other helicopters such as the Eurocopter Dauphin.[29]Defence Bioengineering and Electromedical Laboratory (DEBEL) has been developing an oxygen life-support system to improve the helicopter's high-altitude performance, and as of August 2010 the IAF has ordered development of this system for the Dhruv.[30]
The HAL Dhruv is of conventional design; about 29 percent of its empty weight (constituting 60 percent of the airframe's surface area) is composite materials.[31] It has been reported that the unique carbon fibre composite developed by HAL reduced the helicopter's weight by 50 percent.[32] The high tail boom allows easy access to 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.[9] 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.[33]
The cockpit section of the fuselage is of Kevlar and carbon-fibre construction; it is also fitted with crumple zones and crashworthy seats. The aircraft is equipped with a SFIM Inc four-axis automatic flight control system. Avionics systems include a HF/UHF communications radio, IFF recognition, Doppler navigation, and a radio altimeter; a weather radar and the Omega navigation system were options for the naval variant.[34] IAI has also developed targeting systems and an electronic warfare suite for the Dhruv, as well as avionics for day-and-night flight observation.[27] HAL's claim that the Dhruv is indigenous has been challenged by 5h3 Comptroller and Auditor General of India, who reported that as of August 2010 the helicopter was: "...against the envisaged indigenisation level of 50% (by 2008), 90% of the value of material used in each ALH is still imported from foreign suppliers".[35]
HAL Dhruv MK-III of the Indian Coast Guard
In September 2010, it 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,[9] 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 the IDS in Italy in order to isolate the problem with the early testing of the Dhruv subsequently being criticized as "rushed".[36] In June 2011, HAL has reported that the issue had been resolved and not present in the Dhruv Mk III; a number of alterations both to the design and production had been made to improve the IDS. A programme of retrofitting the Mk I and Mk II was completed by June 2011.[37]
The ALH Mk-III with new Shakti-1H engines has better and improved high altitude performance operating at altitudes over 6 km. It comes with seating for 14 fully equipped troops. DGCA has reportedly praised its crashworthy design as a few accidents have not caused any fatalities.[38]
In September 2024, HAL assigned TimeTooth Technologies, based in Bengaluru, for indigenisation of Rotor Damp System to be used on ALH Dhruv and HAL Prachand. The project involves development and qualification of the system for the next two years followed by its production and supply would be for a period of 5 years and beyond. The majority of the project will be funded by the private company itself. The production order value is expected to exceed $5 million within the 5-year period.[39]
Dhruv Mk.III towed inside the hangar of an Indian Coast Guard patrol vessel
Deliveries of the Dhruv commenced in January 2002, nine years after the prototype's first flight, and nearly eighteen years after the program was initiated.[12]
The Dhruv is capable of flying at high altitudes, as it was an Army requirement for the helicopter to be able operate in the Siachen Glacier and Kashmir regions. In September 2007, the Dhruv Mk.3 was cleared for high-altitude flying in the Siachen Sector after six months of trials.[45][46] In October 2007, a Dhruv Mk.3 flew to an altitude of 27,500 feet (8,400 m) ASL in Siachen.[47] 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 the TM333 engine. As a consequence the Army had to continue relying on the older Cheetah/Cheetal helicopters to meet the shortfall.[48] The more powerful Shakti-1H engine has since been introduced on the Dhruv Mk.3; on one test it carried 600 kg load to Sonam Post against the Army's requirement of 200 kg.[49] The Indian Army received the first batch of Dhruv Mk.3s during Aero India 2011.[50]
In October 2008, Defence Minister A. K. Antony announced that the Indian Navy will deploy the Dhruv in the utility role. The proposed anti-submarine warfare (ASW) variant had been deemed unsuitable by the Navy, which was reportedly dissatisfied with the folding blade performance and maintenance record.[51][52] In 2015, HAL modified the foldable rotor's design to allow the Dhruv to be carried on board light frigates; several Indian Navy helicopters shall receive this modification.[53] The Navy has considered the Dhruv for maritime surveillance and search and rescue roles,[54] and in 2008 a senior Navy official said: "The ALH has a long way to go before the programme matures sufficiently for it to undertake basic naval roles such as search and rescue (SAR) and communication duties."[55] In 2013, the Indian Navy was reportedly interested in the HAL Rudra, the armed version of the Dhruv.[56] On 12 November 2013, the Indian Navy commissioned their first Dhruv squadron (INAS 322, Guardians); Vice Admiral Sinha stated that "In the Navy, Dhruv helicopters had transformed into an advanced search and rescue (SAR) helicopter, which is also used for missions like heliborne operations, and armed patrol with night vision devices".[57]
US Army deploying from Dhruv of Indian Army during a joint military exercise
Civil Dhruv variants are produced for transport, rescue, policing, offshore operations, air-ambulance, and other roles.[58] The Oil and Natural Gas Corporation are to use the Dhruv for offshore operations. Several Indian state governments are to use Dhruvs for police and transportation duties.[44] In March 2011, India's Directorate General of Civil Aviation released a proposed airworthiness directive asking all civilian Dhruv operators to temporarily ground their aircraft due to cracks potentially forming in the tail area, and recommended reinforcing affected areas.[59][60]
Following the 2011 Sikkim earthquake, four Dhruvs conducted rescue operations.[61] In October 2011, Jharkhand's regional government appealed for Mil Mi-17 helicopters as operations of their Dhruvs had been disrupted by prolonged maintenance delays and a major crash.[62][63] In October 2011, The Telegraph reported that a spate of helicopter crashes, including the Dhruv, were alleged to have been caused by low quality maintenance work performed by Pawan Hans Helicopters Ltd.[64]
In February 2012, the Home Ministry reported that the Dhruv remained grounded and that other helicopters such as the Mi-17 were being wet-leased in its place and that in the long term the Dhruv fleet is to be replaced.[65] In February 2012, HAL reported that the Indian Army and Air Force had ordered a further 159 units of Dhruv helicopters.[66]
HAL rolls out the 300th Dhruv Advanced Light Helicopter.
Six Army Dhruvs along with 18 Air Force Dhruvs were used during rescue operations after the 2013 North India floods. Their compact size, agility, ability to carry up to 16 people to heights of 10,000 feet, and to evacuate stranded people from inaccessible regions was praised.[67][68][69] 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.[67][70]

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), the HGSS can conduct magnetic, spectrometric and gravity surveys.[71][72][73] In May 2018, Israel Aerospace Industries was awarded a contract to upgrade cockpits of 150 Dhruv helicopters, in addition to 50 that had been contracted earlier.[74]
On February 5, 2021, the Indian Navy tweeted that it has received the Advanced Light Helicopter MK III (MR) alongside the Indian Coast Guard.[75] In February 2021, HAL announced that it had rolled out the 300th Advance Light Helicopter out of its production line in Bangalore.
As of September 2024, Oil and Natural Gas Corporation (ONGC) chose HAL Dhruv for its operations to fly out personnel and equipment from offshore oil rigs. The helicopters will be operated by Pawan Hans. Dhruv won the competition after a competitive bidding with foreign bidders.[76]
Israel: A civilian Dhruv was leased to the Israeli Defense Ministry in 2004; IAI has also made use of the Defense Ministry's Dhruv for marketing and public relations purposes.[32][77][78]
HAL Dhruv helicopter gifted to Maldives
Maldives: In April 2010, the Indian Navy gifted a Dhruv to the Maldives National Defence Force for conducting search and rescue and medical evacuation,[79] while a second Mk.III equipped with a weather radar was donated in December 2013. The first helicopter is based at Addu Atoll and the second will be based at Hanimaadhoo.[80]
Myanmar: In 2007, Amnesty International stated it possessed evidence that India planned to transfer two Dhruvs to Burma, and pointed to the use of European-sourced components as a possible violation of the European Union (EU) arms embargo against that country.[81][82][83] The Indian government disputed Amnesty's claims and denied any wrongdoing.[84]
Nepal: In early 2004, the first foreign order for the Dhruv was placed by Nepal for two examples.[85] In November 2014, India gifted another Dhruv to Nepali Army as part of a strategic pact.[86][87]
Peru: In June 2008, the government of Peru ordered two air ambulance Dhruvs for use by the Peruvian Health Services.[88]
Turkey: In August 2008, a deal was reportedly finalised with Turkey for three Dhruvs for US$20 million, with plans to buy as many as 17 of the helicopters for use in the medical assistance role.[89][90]
The Dhruv has become the first major Indian weapons system to have secured large foreign sales. In 2004, HAL stated that it hoped to sell 120 Dhruvs over the next eight years,[91] and has been displaying the Dhruv at air shows, including Farnborough and Paris in order to market the Dhruv.[92] HAL had entered into a partnership with Israel Aerospace Industries (IAI) to develop and promote the Dhruv, IAI has also helped develop new avionics and a glass cockpit for newer variants of the Dhruv.[93]
With a unit price at least 15 percent less than its rivals, the Dhruv has elicited interest in many countries, mostly from Latin America, Africa, West Asia, South East Asia and the Pacific Rim nations. Air forces from around 35 countries have made inquiries, along with requests for demonstrations.[94] Flight certification for Europe and North America is also being planned in order to tap the large civilian market there.[95]
South America: HAL has reportedly been negotiating with Bolivia for five Dhruvs; and with Venezuela for up to seven.[89]
Southeast Asia: The Dhruv has also been offered to Malaysia,[97] while it is also being evaluated by the Indonesian Army.[98]
Phillippines: The HAL Annual Report for 2020-21, indicated that the Philippine Coast Guard is interested to potentially buy 7 Dhruvs via Indian-based credit.[99] It is reported that that the PCG is looking at the Dhruv ALH.[100][101] There has been to instances when the capabilities of Dhruv were demonstrated to Philippines. First was when PCG chief visited Indian Coast Guard facility at Goa in 2023 and took part in a "Customer Demonstration Flight" and second was when a three ship flotilla (including INS Delhi, INS Shakti and [[INS Kiltan (P30)|INS Kiltan]]) visited Manila, Philippines in May 2024.[102]
Egypt: Egypt stated in 2022 that it was interested in acquiring the ALH.[103]
Chile: The Dhruv participated in a Chilean tender for eight to ten twin-engined helicopters, conducting a series of evaluation flights to demonstrate the capabilities of its avionics and flight performance; however, it lost out to the Bell 412,[106][107] although there were media accusations of unfair pressure being exercised by the US Government to favour Bell.[94][108]
HAL has secured an order from the Ecuadorian Air Force (EAF) for seven Dhruvs, amidst strong competition from Elbit, Eurocopter and Kazan. HAL's offer of US$50.7 million was about 32 percent lower than the second lowest bid from Elbit.[109] Five helicopters were delivered in February 2009, during Aero India 2009.[110] Both the Ecuadorian Army and Ecuadorian Navy have since expressed interest in the Dhruvs.[111] The Dhruv has been involved in search and rescue, transport, and MEDEVAC missions in the north of the country.[112]
Following the crash of one of the Dhruvs in October 2009, Ecuador reportedly considered returning their six helicopters to HAL amid claims of being unfit for service;[113] EAF commander Genl. Rodrigo Bohorquez stated "If it is a major problem that can't be easily remedied, we would have to return [the Dhruv]." HAL assisted the crash investigation, which found the cause to be pilot error.[114]
In February 2011, the EAF were reported to be satisfied with the Dhruv's performance and was considering further orders.[115] By October 2015, a total of four Ecuadorian Dhruvs had crashed reportedly due to mechanical equipment and Ecuador grounded the type.[116] In October 2015 Ecuador cancelled the contract and withdrew the surviving helicopters from service, non-delivery of parts and high accident rate were cited.[117] In 2016, the Ecuadorian Minister of DefenseRicardo Patiño announced that the remainder of the HAL Dhruv helicopters of the Ecuadorian Air Force, which are stored at the Guayaquil Air Base are for sale and that the Air Force is looking for potential buyers.[118] The Government of Ecuador had unilaterally terminated the contract with HAL citing safety concerns of the helicopters.[119] A HAL spokesman said that while maintenance 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.[120] Quito declined further assistance.[120]
India was expected to order up to 12 Dhruvs outfitted with an onboard emergency medical suite, to be used by the Armed Forces Medical Services for MEDEVAC purposes as of August 2007.[44] The National Disaster Management Authority (NDMA) placed an order for 12 Dhruv helicopters equipped with a full medical suite, including ventilators and two stretchers in 2007.[125]
In June 2008, HAL has secured an order from the Ecuadorian Air Force (EAF) for seven Dhruvs, worth US$50.7 million.[109]
In 2008, it was announced that India's Home Ministry had ordered six Dhruvs.[126]
In August 2008, a deal was reportedly finalised with Turkey for three Dhruvs for US$20 million for use in the medical assistance role.[89][90]
On 4 September 2017, an order of 41 helicopters for Indian Army (40) and Indian Navy (1). The order is to be executed within 60 months The order was be worth ₹6,100 crore (equivalent to ₹86 billion or US$1.0 billion in 2023).[128]
Apart from getting 16 Dhruv Mk III, Indian Coast Guard issued Letter of Intent (LoI) for nine additional units in 2022.[129] In March 2024, Cabinet Committee on Security (CCS) approved the procurement of 34 Dhruv Mk III models. The order of 34 helicopters was signed between MoD and HAL on 14 Match 2024. The Indian Army is to get 25 units while Coast Guard will get 9 units. The order was worth ₹8,073 crore (US$970 million).[130]
As of September 2024, Oil and Natural Gas Corporation (ONGC) chose HAL Dhruv operated by Pawan Hans for its operations to fly out personnel and equipment from offshore oil rigs. An initial order of 10 Dhruvs is expected with the order quantity expected to cross 28 units later.[76]
The initial configuration with a conventional cockpit with mechanical gauges and Turbomeca TM 333-2B2 turboshaft engines. A total of 56 have been delivered to the Indian military.[131][132] Manufacturing began in 2001.[133]
Mk.2
Similar to the Mk.1, except has the newer HAL-IAIglass cockpit.[132] A total of 20 have been delivered to the Indian military.[131] Manufacturing began in 2007.[133]

An improved version equipped with Shakti-1H engines, new electronic warfare (EW) suite and warning systems, automatic chaff and flare dispensers, Integrated Architecture Display System (IADS) with Digital Moving Map, Electro Optical pod, infrared suppressor, health & usage monitoring system, Solid State Digital Video Recorder (SSDVR), Engine Particle Separator and improved vibration control system.[132][134] The first batch were inducted into service in 2012.[135]
Mk.3 Coast Guard
HAL Dhruv operated by Indian Coast Guard
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.[136]
Mk. 3 Navy/Mk.3 MR (Marine Reconnaissance)
Has additional equipment such as a modern surveillance radar and electro-optical equipment to carry out maritime reconnaissance as well as long-range search and rescue missions, an HMG and the capability to mount at least 2 ASW torpedoes.[137]
HAL is currently developing an advanced variant of the ALH Dhruv to address the specific needs of the Indian Navy. The helicopter is to be purpose-built for ship-borne uses.
The UH-M programme has its origin from the Navy's Naval Utility Helicopter (NUH) acquisition programme. The Navy issued a requirement of 111 units of utility helicopters. The programme was cleared by the Defence Acquisition Council (DAC) – the main acquisition panel under the Ministry of Defence (MoD) headed by the then Minister of DefenceNirmala Sitharaman on 25 August 2018 though the Acceptance of Necessity (AoN) document. The cost of the programme was set at ₹21,000 crore (equivalent to ₹280 billion or US$3.4 billion in 2023). 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.[140]
According to a report in April 2022, the Expression of Interest (EoI) to OEMs and Strategic Partners were issued in February 2019. However, the deal was included in the third "positive indigenisation list".[141] Meanwhile, HAL had carried out a joint study of ALH Dhruv to increase the MTOW to 5.7 tonnes, reduce the empty weight and increase the overall payload capacity to 600 kg. The modifications also included "reduced stowage dimensions to meet requirement with foldable two segment blades and modified upper control system and Aircraft Ship Integrated Secure and Traverse (ASIST) traversing interface for ship deck." The programme is to replace the Navy's ageing Chetak fleet.[142] The Indian Navy is to place an order of at least 50 helicopters in the first phase.[143][144]
The maritime wheeled version of Dhruv having segmented Main Rotor Blades (MRBs) and Main Rotor Head (MRH) in pre-cone configuration completed its first flight on 30 June 2022.[145] By March 2023, tail boom folding has been demonstrated. Reportedly, the UH-M will also showcase anti-ship missile and torpedo firing capability.[146]
On 16 March 2023, the Defence Acquisition Council (DAC) approved the Utility Helicopter-Maritime programme for the Indian Navy.[147]
On 20 October 2024, a report from The Economic Times revealed that the prototype of Utility Helicopters-Marine (UH-M) helicopter is under construction while the first flight is expected by May 2025. Its multirole capabilities will include transportation of personnel, cargo delivery and CASEVAC. Simultaneously, the new technologies developed for the new helicopter is also being tested on a testbed. The design is mostly based on the earlier Dhruv and includes extensive modifications to fit inside a ship-based hangar. The modifications includes foldable tail boom as well as foldable rotor blades and a nose-mounted surveillance radar. The Navy needs 111 of these helicopters.[148]

There have been several accidents involving Dhruv Helicopters (ALH) ever since the Hindustan Aeronautics Limited began producing them in 2002, the Indian Government reported to Parliament on 8 March 2016. “Out of 16 accidents, 12 occurred due to human error and environmental factors and the remaining four occurred due to technical reasons,” Minister of State for Defence Rao Inderjit Singh informed the Indian parliament.[119]
On 8 March 2023, a MK III naval variant made an emergency water landing off the coast of Mumbai, prompting the navy to ground the aircraft pending further investigation. All three crew members were rescued.[156][157]
On 26 March 2023, an Indian Coast Guard ALH Dhruv Mark 3 helicopter crashed during soon after takeoff from a height of 25 ft near the main runway at Kochi Airport. Three Indian Coast Guard servicemen on board survived with minor injuries.[158][159]
The aluminium booster control rods, which are found to be the main reason of the recent accidents, are being replaced by steel ones. According to reports, the collective control rod has been replaced in the entire helicopter fleet while that of the other two rods (lateral and longitudinal) in the ALH fleet is underway, and is planned to be completed by end of June 2024.[160][161]
On 2 September 2024, an Indian Coast Guard Dhruv Mk 3 (CG 863) of 835 Squadron had conducted an emergency landing in the Arabian Sea at night when it was deployed for medical evacuation of a seriously injured crew on board Indian-flagged motor tanker Hari Leela about 45 km from Porbandar. The helicopter was launched at around 2300 hrs IST and crash landed at 2315 hrs while approaching the motor tanker ship. However, the injured crew was rescued by an ICG Ship afterwards. Out of the 2 pilots and 2 divers of the helicopter, one diver (diver Gautam Kumar) was rescued by a search and rescue team while the search for the others were on. The wreckage was also found while ICG deployed four ships and two aircraft for search and rescue. Navy also joined in with 2 specialised ships and diving ships. It was the same helicopter which rescued 67 people during the recent cyclonic weather in Gujarat.[162] Later, 2 missing personnel's body was recovered. They were later known to be pilot Vipin Babu and diver Karan Singh. For the incident, ICG grounded the Dhruv fleet for inspection.[163] As of 6 September, the search for the captain is on along with the process of salvaging the helicopter. The average depth of search and rescue ops is 55 m.[164] On 10 October the remains of Commandant Rakesh Kumar Rana, the captain of the helicopter was located and recovered about 55 km from southwest of Porbandar. He was cremated with full military honours the next day. This was after a total of more than 70 air sorties and 82 ship days of search efforts by the ICG and the Indian Navy. With this the massive search operation was called off.[165]
On 2 October 2024, an Indian Air Force ALH air-dropping relief material in flood-hit Bihar made a forced landing in a swamp following engine failure. All 4 crew were rescued.[166][167]
