India Expands Air Defense with Helicopter-Based Drone Interdiction Tactics

“In the future, 156 additional units will be inducted into the fleets of both services: 66 to the IAF and 90 to the Indian Army. These 156 helicopters will be delivered by 2032.”

Exercise Rotor Clap III at Pokhran and its purpose

Exercise Rotor Clap III concluded on August 2 after a week-long helicopter drill at the Pokhran firing range in Rajasthan. Conducted under the IAF South Western Air Command, the exercise validated tactics to shoot down unwarranted low-flying loitering munitions and drones, and it activated units at forward operational bases in Rajasthan that border Pakistan. Rotor Clap III is the third iteration of a drill inaugurated in 2019; its latest editions followed India’s launch of Operation Sindoor in May 2025 and are explicitly framed as responses to drone incursions identified during that operation.

Helicopter platforms used and their basing

Rotor Clap III involved rotary-wing platforms across the IAF fleet, including Apache, Prachand, Mi-25/35P, Rudra, and Mi-17V-5 helicopters. The exercise emphasized assets already based in Rajasthan: Prachands have been deployed at the IAF Jodhpur air station since 2022, and Apaches are with the 451 Army Aviation Squadron based in Jodhpur. The field activity in Rajasthan suggests these helicopters could form an airborne leg of New Delhi’s Mission Sudarshan Chakra to intercept and neutralize aerial objects near the border.

Prachand, Rudra and Apache: numbers, production, and timelines

The Prachand — the indigenously developed attack helicopter by Hindustan Aeronautics Limited (HAL) — is described as the backbone of India’s helicopter fleet for these tasks. Currently the IAF and Indian Army Aviation Corps have 10 and 5 Prachands in service respectively. A further 156 Prachand helicopters (66 for the IAF and 90 for the Army) are planned for induction by 2032, with HAL partnering with Adani Defense Systems and Technologies Limited and Bharat Earth Movers Limited (BEML) to boost annual production.

The Rudra attack helicopter, also made by HAL, is stated to be in broad service: the IAF has one operational Rudra squadron and is expected to induct three more, while the Indian Army operates around 75 Rudras across five operational aviation wings. In addition, both services have 28 advanced Apache helicopters in service (22 with the IAF and six with the Indian Army), and India has retained capability to produce parts of the Apache, including its fuselage.

How Mission Sudarshan Chakra has expanded

Mission Sudarshan Chakra is being positioned beyond a purely ground-based air defense shield. Rotor Clap III indicates the mission’s scope now includes using helicopters to interdict drones and loitering munitions. The exercise argues that rotary platforms — capable of flying low to evade low-level radars — can perform interdiction missions close to the border. Analysts in the source material note a trade-off: using helicopters to shoot down low-cost drones is not as cost-effective as ground-based air defense guns or jammers, but it is far less expensive than firing costly missile interceptors.

Options laid out for Pakistan’s military response

The source sets out three concrete options for Pakistan to blunt India’s evolving tactics. First, Pakistan is advised to induct high-speed loitering munitions with speeds exceeding Mach 0.5, on the premise that such speed would make helicopter-based interdiction more difficult. Second, Pakistan can attempt to close the low-level radar detection gap by deploying advanced long-range electro-optical sensors that do not rely solely on line-of-sight radar horizons, along with additional low-level radar deployment. Third, the Pakistan Army and Air Force are urged to conduct joint exercises to develop a coordinated response and preserve conventional deterrence at the tactical level.

What this means for the IAF, the Pakistan armed forces, and regional dynamics

  • For the IAF: Rotor Clap III is a test of tactics and force structure — integrating rotary assets into Mission Sudarshan Chakra expands options for low-altitude interdiction and leverages ongoing production plans for Prachand and Rudra platforms.
  • For the Pakistan armed forces: The source recommends accelerating both high-speed loitering-munition procurement and sensor/radar deployments, and prioritizing joint Army-Air Force exercises to respond to low-level rotary threats.
  • For regional observers: The exercise, and the source’s note of possible Israeli assistance — including the cited example that an Israeli Air Force Apache shot down six drones in minutes during the 2025 12-day Iran-Israel war — underscores how tactics used elsewhere are informing local doctrine; the source also cites a newly released Amnesty International report alleging that India has aided Israel’s war effort against Iran.

Rotor Clap III is explicit about widening New Delhi’s defensive toolkit: not abandoning ground-based measures but adding a helicopter interdiction option that sits between jammers and missile interceptors in cost and capability. The concrete choices Pakistan now faces — faster loiterers, denser low-level sensing, and joint tactical rehearsal — will determine whether that airborne leg delivers operational surprise or becomes another countered capability on a contested frontier.
