In a major stride toward self-reliance in defense technology, the Indian Air Force (IAF) has unveiled Project Vayu Baan (Air Arrow). This initiative marks the development of India’s first Helicopter-Launched Drone System, officially categorized as an Air-Launched Effect (ALE). Developed by the IAF’s Directorate of Aerospace Design (DAD), the project aims to integrate unmanned systems with manned rotary-wing platforms to enhance lethality and survivability in contested airspaces.

Technical Overview: How Vayu Baan Operates

The Vayu Baan is a compact, autonomous drone engineered for mid-air deployment from moving helicopters.

1. Deployment: The drone is dropped from a mother ship (such as the Prachand LCH or ALH Dhruv).
2. Activation: Post-release, the system unfolds its wings and activates its propulsion system to transition into controlled flight.
3. Mission Profile: It functions as a "Loyal Wingman" for helicopters, capable of switching between high-definition ISR (Intelligence, Surveillance, and Reconnaissance) and acting as a Precision-Guided Munition (Kamikaze drone).

Key Features and Specifications

The Vayu Baan system is tailored for the specific challenges of the modern battlefield, particularly along India's mountainous borders:

• Stand-off Range: The drone can travel over 50 km after release, allowing the host helicopter to remain outside the range of enemy MANPADS (Man-Portable Air-Defense Systems).
• Endurance: It offers a loitering time of approximately 30 minutes, providing a window to scout targets or wait for optimal strike conditions.
• GNSS-Denied Navigation: A critical feature is its ability to operate in electronic warfare (EW) environments. It uses advanced flight control systems to navigate even when GPS/GNSS signals are jammed.
• Advanced Sensors: Equipped with EO/IR (Electro-Optical/Infrared) sensors, ensuring operational efficiency during both day and night missions.
• Swarm Potential: A single helicopter can deploy multiple units, creating a localized "mini-swarm" to overwhelm enemy defenses through saturation.
