Hindustan Aeronautics Limited (HAL) has successfully completed the first ground run of the upgraded PTAE-7 engines, developed for the indigenous CATS Warrior unmanned combat aerial vehicle (UCAV). The PTAE-7 engine, originally developed in partnership with Safran Helicopter Engines of France during the 1980s, has been extensively upgraded by HAL to meet modern performance requirements. The recent tests, conducted in late July 2025, demonstrate improved thrust and fuel efficiency, critical for the CATS Warrior’s operational capabilities. This advanced UCAV, designed under the Combat Air Teaming System (CATS) program, is intended to operate seamlessly alongside manned fighter jets of the Indian Air Force, offering enhanced surveillance and combat support. The developmental timeline sets the first flight of the CATS Warrior by late 2025 or early 2026. This achievement aligns with India’s strategic emphasis on indigenous defense technology development and self-reliance under the Make in India initiative, marking a crucial step in reducing dependence on foreign systems and boosting domestic aerospace manufacturing capabilities.
