Stealthy Drone Paves the Way for a New Era in Air Combat
A New Era in Air Combat
The Hindustan Aeronautics Limited's Combat Air Teaming System (CATS) programme has reached a critical milestone with the successful completion of the engine ground run of the full-scale CATS Warrior demonstrator. This achievement marks a significant step towards the development of a stealthy unmanned combat aerial vehicle (UCAV) designed to fly alongside manned fighters like the Tejas and AMCA.
Stealthy Design
The CATS Warrior boasts a unique design that enables it to evade enemy radar. Its serpentine air intake shields the engine face from direct radar visibility, while its radar absorbent material coatings with over 99% attenuation ensure that the aircraft remains undetectable. The blended-wing design optimised for low radar cross-section further enhances the UCAV's stealth capabilities.
Engine Ground Run
The engine ground run was conducted at HAL's Bengaluru campus on January 11, 2025, validating the integration of the twin PTAE-W engines with the airframe, fuel systems, and flight control architecture. This achievement is a testament to the expertise of HAL and its partners in developing cutting-edge aerospace technology.
Public-Private Partnership
The full-scale demonstrator was built in a compressed 14-week timeline through a public-private partnership between HAL and Tata Elxsi. This collaboration has enabled the development of a sophisticated UCAV with advanced features such as airframe assembly, fuel storage systems, and landing gear development.
OMCA: A Critical Enabler
The Optionally Manned Combat Aircraft (OMCA) serves as a critical enabler within the CATS architecture. Based on the Indian Air Force's Kiran Mk-II jet trainer, the OMCA has completed its maiden unmanned flight validation and functions as a cost-effective testbed for avionics, datalinks, mission systems, and autonomous control experimentation tied to the Warrior roadmap.
Integration with Rafale F4 Fleet
The Indian Air Force is also pursuing integration of the CATS Warrior with its forthcoming Rafale F4 fleet through open API access. This will enable Indian engineers to interface directly with the aircraft's mission computers without requiring French modification of the core combat code.
Projected Requirements
The Indian Air Force has signalled a projected requirement of approximately 100 CATS Warrior units, sized to support three to four loyal wingmen per manned strike package. HAL is targeting a unit cost of approximately $5 million per drone, making it an attractive option for the Indian military.
