VEM Technologies Develops SATCOM-Linked ‘Chaser’ Loitering Munition

India’s private defense sector is experiencing a paradigm shift with the foray of VEM Technologies into the realm of advanced military technology. The company, based in Hyderabad, has introduced the “Chaser,” an indigenous loitering munition engineered to redefine battlefield dynamics, particularly in Intelligence, Surveillance, Tracking, Attack, and Reconnaissance (ISTAR) operations.

Overview of the Chaser

Currently in the phase of advanced prototype testing, the Chaser is designed for dual functionality: long-endurance flight and precision striking capabilities. This positions it as a formidable contender alongside globally recognized systems such as the Shahed-136. Emphasized as a flexible weapon for the modern and networked battlefield, the Chaser integrates autonomous navigation with human oversight, enabling it to pursue both moving and stationary targets over extensive distances.

Revolutionary SATCOM Technology

One of the standout features of the Chaser is its satellite communication (SATCOM) link, which fundamentally transforms traditional operational constraints. By overcoming line-of-sight limitations, military operators located hundreds of kilometers away can receive real-time video feeds and manage the drone’s operations deep into potentially hostile territory. This level of accessibility allows for an unprecedented tactical advantage in combat scenarios.

Prioritizing Safety with MITL Architecture

Safety remains paramount in the Chaser’s design, particularly regarding its engagement protocols. The drone utilizes a Man-in-the-Loop (MITL) architecture, ensuring that human operators maintain control during critical moments. Before carrying out any strike, the operator can visually confirm the target via onboard cameras, significantly minimizing the risk of collateral damage or civilian casualties.

Moreover, the Chaser is equipped with a mid-air abort function. Should the ground situation evolve unpredictably, the operator has the option to cancel the strike and redirect the munition towards a different threat, showcasing the system’s adaptability.

Advanced Sensor Capabilities

To excel in diverse weather and lighting conditions, the Chaser boasts a comprehensive sensor package. Its Electro-Optical/Infrared (EO/IR) cameras are designed for clear imaging throughout the day, during night operations, and even under thermal conditions. For challenging environments, such as heavy cloud cover or low visibility, the drone can further be enhanced with Synthetic Aperture Radar (SAR), allowing it to effectively locate and identify targets.

Precision Strike Mechanism

When it comes to executing a strike, the Chaser is built for versatility. Its seeker provides a 360-degree field of view, permitting attacks from multiple angles. This capability enables military forces to conduct lethal top-down dives against well-fortified tanks or lateral strikes against heavily defended buildings, thereby exploiting vulnerabilities in enemy defenses.

Specifications and Performance Metrics

The Chaser first captured attention during the Aero India 2025 expo, positioned as a potent combination of endurance and speed. The drone has a takeoff weight of approximately 150 kilograms and is capable of carrying a 25-kilogram explosive payload—suitable for neutralizing radar installations, command posts, and armored vehicles alike.

Its propulsion system is powered by a 27-kilowatt (37 horsepower) Wankel engine, allowing the drone to cruise at speeds between 195 and 220 km/h. During an attack maneuver, it can achieve a maximum speed of 270 km/h. To ensure rapid deployment, the Chaser is launched from a storage canister using a rocket booster, showcasing its readiness for swift military action.

Operational Range and Endurance

Remarkably, the Chaser boasts an operational range of 1,000 kilometers and can maintain flight for up to six hours, operating at altitudes of 16,000 feet. This altitude keeps it well above the reach of most small-arms fire, further enhancing its survivability during missions.

The Path to Mass Production

VEM Technologies is harnessing decades of aerospace expertise in the development of the Chaser, with a rich background that includes the manufacturing of key structural components for India’s HAL Tejas fighter jet and the BrahMos supersonic cruise missile. The company is well on its way to transitioning the Chaser from a prototype to mass production within its new Integrated Defence Systems Facility, located in Yelgoi near Zaheerabad. This expansive 511-acre site represents a monumental investment of ₹1,000 crores, reflecting India’s commitment to fostering cutting-edge defense technologies.

Scheduled for full commissioning by 2026, this facility is poised to become one of India’s largest private defense manufacturing hubs, dedicated to equipping the armed forces with the latest in unmanned aerial technology.
