The silent threat below: Why Indian Navy needs many more ASW helicopters

India’s navy faces mounting pressure to bolster its anti-submarine warfare (ASW) capabilities amid rising tensions in the Indo-Pacific region, where the undersea domain has emerged as a critical front in modern naval strategy. With adversaries such as Pakistan and China fielding increasingly sophisticated submarine forces, the Indian Navy must urgently expand its fleet of ASW helicopters to maintain maritime superiority. Current numbers fall far short of what is required to secure India’s vast maritime interests, spanning from the Bab el-Mandab in the west to the Strait of Malacca in the east. The Indian Navy has inducted 21 of the 24 MH-60R Seahawk helicopters ordered from the United States, marking a significant step forward in enhancing its ASW capabilities. These helicopters, equipped with advanced dipping sonars, sonobuoys, magnetic anomaly detectors, and lightweight torpedoes, play a crucial role in detecting, tracking, and neutralizing underwater threats. However, despite this progress, the number of ASW helicopters remains insufficient to cover the extensive maritime territory under India’s responsibility. The Navy’s modernization efforts have been robust, but the induction of helicopters has lagged behind the expansion of its surface fleet. Recent developments highlight the urgency of this issue. Pakistan has begun inducting the first of eight Chinese-built submarines, adding to the already formidable submarine presence in the region. Meanwhile, China’s People’s Liberation Army Navy operates over 60 submarines, according to the Observer Research Foundation (ORF). This growing submarine armament poses a direct challenge to India’s naval dominance, particularly in scenarios where stealthy submarines could disrupt vital sea lanes of communication or threaten aircraft carrier battle groups. To address this imbalance, the Indian Navy must accelerate the procurement of both the Naval Multi-Role Helicopter (NMRH) and the Naval Utility Helicopter (NUH). These programs aim to provide a domestic alternative to foreign-manufactured ASW platforms, ensuring self-reliance in defense production. The need for immediate action is underscored by the fact that while India has initiated the procurement of additional P-8I long-range maritime patrol and ASW aircraft through the Acceptance of Necessity (AoN) process, these aircraft will require several years before entering active service. In contrast, ASW helicopters can offer immediate and effective coverage, complementing the Navy’s existing assets. The strategic importance of underwater warfare has grown exponentially in recent years. Modern submarines are designed to operate undetected for prolonged periods, making them potent tools for disrupting enemy logistics and conducting surprise attacks. Incidents involving submarine activity in the broader Indian Ocean region have demonstrated how swiftly underwater threats can reshape the balance of power. For instance, the presence of submarines near key choke points such as the Strait of Hormuz or the Andaman Sea could have severe implications for regional stability and trade routes. Naval experts emphasize that the integration of ASW helicopters into the fleet is essential for maintaining situational awareness in areas where traditional radar systems are ineffective. These helicopters can deploy sonobuoys to create a network of acoustic sensors, allowing for continuous monitoring of the ocean floor. Their ability to conduct sustained surveillance missions ensures that potential threats are identified and neutralized before they can cause damage. This capability is especially vital given the increasing sophistication of submarine technology, which includes advanced noise reduction features and stealthy propulsion systems. As the Indo-Pacific becomes more contested, the Indian Navy’s ability to project power and safeguard national interests hinges on its capacity to dominate the undersea battlespace. While the acquisition of new warships and aircraft is critical, the effectiveness of these platforms will ultimately depend on the helicopters that accompany them. By prioritizing the procurement and indigenous production of ASW helicopters, India can bridge a critical capability gap and ensure its naval forces remain prepared for the challenges of the future.
