Honeywell Aerospace announced the launch of HON6000, a high-performance turbofan engine that is designed to power collaborative combat aircraft, advanced unmanned aerial vehicles, light combat aircraft, and advanced jet trainers. The engine is designed to support the operational needs of collaborative combat aircraft. These autonomous platforms are intended to operate alongside crewed fighter aircraft, taking on high-risk missions in challenging environments while maintaining coordination with traditional military aircraft.
The company mentioned that “engines powering collaborative combat aircraft must deliver high efficiency, reliability, and cost effectiveness.” Such capabilities are crucial as these aircraft are designed to operate at scale in complex combat scenarios.
The HON6000 has been developed using Honeywell’s established engine architecture and is optimized for medium-sized collaborative combat aircraft platforms. Honeywell said the engine offers a high power-to-weight ratio within its thrust class to support performance requirements in demanding operational environments.
According to Precedence Research, the aircraft turbofan engine market size was USD 112.05 billion in 2025 and is projected to increase from USD 117.89 billion in 2026 to approximately USD 186.20 billion by 2035, expanding at a CAGR of 5.21% from 2026 to 2035, driven by rapid growth in air travel, growing demand for fuel-efficient engines, rapid advances in engine technology, and rising focus on sustainability.
Advancing Propulsion Systems for Autonomous Aircraft
The introduction of the HON6000 expands Honeywell’s propulsion portfolio for next-generation defense platforms. This new engine complements the previously announced SKYSHOT1600 engine, which is designed for smaller collaborative combat aircraft.
Together, the two engines aim to support manufacturers in developing small and medium-sized autonomous aircraft platforms.
According to Honeywell, the HON6000 has been engineered to provide thrust and responsiveness for collaborative combat aircraft to operate alongside crewed fighter aircraft on long-range missions. Additionally, the engine supports autonomous flight operations while maintaining predictable performance and operational reliability.
