India’s efforts to develop advanced autonomous strike capabilities are accelerating as National Aerospace Laboratories and Solar Defence & Aerospace Limited collaborate on a 150-kg class loitering munition UAV designed for deep-strike missions.
The partnership, formalized in November 2025, aims to transform the concept into a fully operational system, with prototype testing expected to begin from 2028. The initiative represents a major step in strengthening India’s indigenous long-range strike drone capabilities.
The proposed platform is a long-endurance loitering munition capable of targeting high-value assets deep within hostile territory. It is expected to offer a range of around 900 kilometers and endurance of 6 to 9 hours, enabling extended loitering before executing strikes. The UAV will carry a 15-kg warhead, suitable for engaging targets such as radar installations, air defense systems, logistics hubs, and command centers.
A key technological feature is an indigenous Wankel rotary engine developed by NAL, known for its compact design, lightweight structure, and high power-to-weight ratio. The engine has already received flight clearance from CEMILAC, paving the way for future testing.
The system is being designed with low radar cross-section characteristics to enhance survivability in contested airspace. It will also feature the ability to operate in GPS-denied environments using vision-based AI navigation, reducing reliance on satellite signals in electronically contested scenarios.
Additionally, the drone will be equipped with AI-enabled electro-optical/infrared sensors capable of automatic detection, recognition, and identification of targets. Once a target is confirmed, the system can autonomously guide itself during the terminal phase, enabling precise strikes with minimal operator intervention.
