A 5.5-tonne, twin-engine, multirole helicopter, the Dhruv serves the Indian Armed Forces, Coast Guard, and civilian operators in roles ranging from search and rescue (SAR) to armed combat. Despite its operational success, the program has faced challenges, including safety concerns, grounding incidents, and export setbacks. This detailed note explores the ALH program’s progress, production, indigenization, avionics, roles, armaments, costs, comparisons, and future prospects, drawing inferences and providing recommendations.

Abstract The Advanced Light Helicopter (ALH) Dhruv, developed by Hindustan Aeronautics Limited (HAL), is a 5.5-tonne, twin-engine, multirole helicopter integral to India’s defense and self-reliance goals under “Aatmanirbhar Bharat.” As of January 2024, HAL has delivered over 400 ALHs, with ~330 operational across the Indian Army, Air Force, Navy, and Coast Guard for roles like search and rescue, transport, and armed combat (Mk-IV Rudra). Contracts for 106 Mk-III/IV units and a potential 111 Naval Utility Helicopters aim for 100–150 deliveries by 2030, supported by a 30–40 units/year production capacity. Powered by the Shakti engine (HAL-Safran JV), the ALH achieves 60–65% indigenization, with avionics including glass cockpits, EO systems, and indigenous EW suites from BEL and DRDO. Despite operational success, 28 crashes and a January 2025 grounding highlight reliability concerns, impacting exports (e.g., Ecuador). Costing ~₹100–150 crore/unit, the program has seen ~₹42,573 crore invested, with ₹19,600–22,600 crore projected for 2025–2030. Competitive with helicopters like Airbus H145M, the ALH excels in high-altitude operations but lags in reliability. HAL must enhance quality control, diversify engine sources, and boost exports to solidify the ALH’s strategic role in India’s defense ecosystem.
