In a significant development that has reverberated through India’s defense ecosystem, the Indian Armed Forces recently grounded their entire fleet of Advanced Light Helicopter (ALH) Dhruv following a series of incidents, raising serious questions about reliability and safety. As investigations deepen into the root causes, French aerospace company Safran, a key partner in the ALH program through its supply of Shakti engines, has found itself under scrutiny. This unfolding situation not only highlights concerns over the ALH-Dhruv’s operational integrity but also casts a shadow on India’s broader ambitions for self-reliance in defense manufacturing.
The ALH-Dhruv, designed and manufactured by Hindustan Aeronautics Limited (HAL), has been a flagship project of India’s indigenous defense industry since its induction in 2002. Over 300 units serve across the Indian Army, Air Force, Navy, and Coast Guard, performing roles ranging from troop transport and reconnaissance to search-and-rescue and medical evacuation. However, the helicopter has been plagued by a troubled history of accidents and technical issues, with multiple incidents prompting temporary groundings over the years.
The latest decision to ground the fleet came after a string of mishaps, with reports suggesting that the most recent incident involved a crash during a routine training sortie, resulting in casualties. While HAL has initiated a comprehensive safety review, defense sources indicate that preliminary findings point to potential issues in the helicopter’s critical systems, including its powerplant and control mechanisms. This has led to intensified focus on the Shakti engine, a joint development between HAL and Safran Helicopter Engines, which powers the ALH-Dhruv and its variants.
Safran Helicopter Engines, a leading global manufacturer, collaborated with HAL to develop the Shakti engine (also known as the Ardiden 1H1), a derivative of Safran’s Ardiden engine family tailored for Indian requirements. The Shakti engine, which replaced the earlier Turbomeca TM333-2B2 engine used in initial ALH variants, was introduced to provide greater power and reliability, especially for high-altitude operations in regions like the Himalayas. Over 500 Shakti engines have been produced, powering not only the ALH-Dhruv but also the Light Combat Helicopter (LCH) Prachand and weaponized ALH Rudra.
While HAL bears primary responsibility for the ALH-Dhruv as the helicopter’s designer and manufacturer, Safran’s involvement as a key supplier has drawn attention. Defense experts and military officials are reportedly examining whether the Shakti engine’s integration with the ALH platform has introduced unforeseen vulnerabilities. Issues such as engine reliability, maintenance protocols, and compatibility with the helicopter’s overall design are being scrutinized.
The spotlight on Safran also stems from broader concerns about foreign partnerships in India’s defense sector. Critics argue that reliance on foreign technology, even in collaborative projects, can create dependencies that undermine India’s goal of self-reliance under the ‘Make in India’ and ‘Atmanirbhar Bharat’ initiatives. Some have pointed to past instances where Safran allegedly hesitated to share critical technologies, such as in the stalled Kaveri engine program for fighter jets, as evidence of the challenges in such partnerships.
The grounding of the ALH-Dhruv fleet has far-reaching implications for the Indian Armed Forces. As a versatile platform, the helicopter plays a pivotal role in operations across diverse terrains, from the deserts of Rajasthan to the high-altitude regions of Ladakh and the Northeast. Its absence has forced the military to rely on alternative platforms, such as older Chetak and Cheetah helicopters, which are nearing the end of their operational lifespans and lack the modern capabilities of the ALH.
The disruption has also affected missions critical to national security, including border patrols along the Line of Actual Control (LAC) with China and counter-insurgency operations in the Northeast and Jammu & Kashmir. Additionally, the grounding has impacted humanitarian and disaster-relief efforts, where the ALH-Dhruv has proven invaluable in delivering aid to remote areas during natural calamities.
HAL has responded to the crisis by launching a thorough investigation into the ALH-Dhruv’s issues, with teams analyzing flight data recorders, wreckage, and maintenance records to pinpoint the root causes. The company has also engaged with the Indian Armed Forces to implement safety upgrades, including potential replacements of critical components like control rods, which have been implicated in past incidents. HAL’s leadership has emphasized its commitment to resolving the issues swiftly, acknowledging the helicopter’s importance to India’s defense readiness.
However, the involvement of Safran in addressing engine-related concerns remains a critical factor. Reports suggest that HAL and Safran are working closely to assess the Shakti engine’s performance, with possible upgrades or modifications on the horizon. The outcome of this collaboration will likely influence not only the ALH-Dhruv’s future but also Safran’s standing as a partner in other Indian defense projects, such as the Indian Multi-Role Helicopter (IMRH) program.
