• The Indian Army has received Sabal-20 logistics drones, developed by Endure Air Systems, for deployment in the eastern sector. Simultaneously, the Indian Institute of Technology (IIT), Kanpur, has unveiled a groundbreaking Metamaterial Surface Cloaking System (MSCS), named Analakshya, marking a major advancement in stealth technology.

Sabal-20 Logistics Drones:

• Developer: Endure Air Systems, incubated at IIT Kanpur in 2018.
• Type: Electric unmanned helicopter based on variable pitch technology.
• Payload Capacity: Up to 20 kg.

Capabilities:

• Long-range deliveries.
• High-altitude operations.
• Precision logistics missions.

Equipped with advanced Vertical Take-Off and Landing (VTOL) technology, allowing seamless operations in confined and rugged terrains.

Low RPM design: Reduces noise and provides a low aural signature, enhancing stealth in sensitive missions.

Analakshya: Metamaterial Surface Cloaking System

• The Metamaterial Surface Cloaking System (MSCS) is an advanced stealth technology developed by IIT Kanpur.
• It manipulates electromagnetic waves to provide cloaking against radar detection, thermal imaging, and motion sensors.
• Made using metamaterials, which have engineered properties to control wave behaviour.
• Provides near-perfect wave absorption across a broad electromagnetic spectrum.
• Lightweight, ultra-thin, and flexible, suitable for diverse terrains and climates.
• Ideal for military camouflage, covering soldiers, vehicles, and aircraft to evade detection.
• Protects against Synthetic Aperture Radar (SAR) imaging and radar-guided missiles.
• Can be adapted for aircraft windshields and radar-absorbing textiles.
• More efficient than traditional stealth materials like heavy ceramics.
• Potential for active camouflage systems to dynamically adjust to environments.
• Scalable for use in both ground-based and aerial platforms.
• Adaptable for high-speed aircraft and extreme operational conditions.
