India’s push toward integrating loitering munitions and air-launched drones into battlefield operations has taken a new step with Project Vayu Baan, an indigenous program proposed by the Indian Air Force.
The project was formally detailed in a Request for Proposal (RFP) issued on March 25, 2026, inviting Indian defence firms to develop a compact Air-Launched Effects (ALE) system that can be deployed directly from helicopters. The concept aims to transform frontline helicopters into mobile launch platforms capable of deploying reconnaissance drones or precision strike loitering munitions during combat missions.
Quick Facts
- Program: Project Vayu Baan
- Issued By: Indian Air Force
- Concept: Air-Launched Effects (ALE)/Helicopter-Launched drone system
- Launch Platform: Military helicopters
- Payload: 500 g to 1 kg
- Range Modes: 80 km (15 minutes) / 50 km (30 minutes)
- Altitude Envelope: 150 ft – 8,000 ft
- Delivery Timeline: Within 12 months of contract signing
Transforming Helicopters into “Launch Nodes”
One of the most innovative aspects of Project Vayu Baan is its launch concept.
Instead of being mounted externally on pylons, the system is designed to be deployed directly from helicopter doors or hatches. Once released, the drone unfolds and begins its mission autonomously.
This approach effectively turns helicopters into airborne drone carriers or “launch nodes”, enabling them to deploy loitering munitions or reconnaissance drones without exposing the aircraft to enemy air defences.
The system is expected to be compatible with several helicopters in Indian service, including:
- HAL Prachand
- HAL Dhruv
- Mil Mi-17
This integration could significantly enhance the strike and reconnaissance capabilities of these platforms during high-intensity battlefield operations.
Dual Range and Endurance Modes
The March 2026 RFP provides clear operational specifications, which are critical for evaluating the system’s potential.
The drone will operate in two distinct mission modes:
Long-Range Strike Mode
- Range: 80 km
- Endurance: 15 minutes
Extended Loiter Mode
- Range: 50 km
- Endurance: 30 minutes
This dual configuration allows the system to perform both rapid precision strikes and extended surveillance missions, depending on the operational requirement.
Payload Flexibility
Another key feature of the Vayu Baan system is its modular payload capability.
The drone is designed to carry payloads between 500 grams and 1 kilogram, which can include:
- Electro-Optical / Infrared (EO/IR) sensors for reconnaissance and targeting
- 500-gram warhead for loitering munition strike missions
- Integration with 57 mm or 80 mm rocket systems
This versatility means the system can operate as both a surveillance drone and a precision strike weapon depending on mission needs.
Nap-of-the-Earth Flight Profile
According to the RFP, the drone will operate within an altitude envelope between 150 feet and 8,000 feet.
Flying at very low altitude allows the drone to perform “Nap-of-the-Earth” flight, where it uses terrain masking to remain hidden from enemy radar systems.
This capability is particularly valuable in mountain warfare environments, where terrain can provide natural cover during drone operations.
Designed for GNSS-Denied Warfare
Modern battlefields increasingly feature intense electronic warfare and GPS jamming, which can disable many unmanned systems.
Project Vayu Baan specifically requires the drone to operate in GNSS-denied environments, meaning it must continue functioning even when satellite navigation signals are jammed or unavailable.
This capability is considered crucial for operations along contested regions such as the northern borders, where electronic warfare is expected to play a major role in future conflicts.
Opportunity for India’s Defence Industry
The RFP for Project Vayu Baan was issued through the Regional Aerospace Innovation Division – Gandhinagar (RAID-GN), a specialized innovation unit supporting the Indian Air Force.
The program offers a significant opportunity for Indian defence startups and aerospace companies to participate in the development of next-generation drone warfare technologies.
Notably, the project has a fast-track development timeline, with the IAF seeking delivery within 12 months of contract signing—highlighting the urgency of integrating loitering munition capabilities into helicopter operations.
