The transition from the aging KC-10 Extender to the Pegasus represents a significant technological leap, setting the stage for a new era of air-to-air refueling.

Autonomous Systems

While the KC-46 Pegasus represents a substantial upgrade, the USAF is not content to rest on its laurels. The military is actively exploring the integration of autonomous systems to revolutionize the air-to-air refueling process, leveraging the existing KC-135 Stratotanker fleet as a testbed.

Cooperative Research and Development Agreements (CRADAs)

Through Cooperative Research and Development Agreements (CRADAs), the USAF is partnering with innovative aviation technology startups to develop and test cutting-edge autonomous systems. These systems aim to enhance the safety, efficiency, and overall capability of air-to-air refueling operations, ultimately reducing pilot workload and increasing mission effectiveness.

The Future of Air-to-Air Refueling Autonomous Systems

Enhancing Situational Awareness and Capability

The integration of autonomous systems is expected to augment the flying tasks, freeing up the aircrew’s attention to focus on other critical mission objectives. By automating certain refueling processes, the USAF can enhance the overall situational awareness and capability of its air-to-air refueling operations, particularly in time-sensitive and high-stress environments.

Demonstration and Deployment Timeline

The first demonstration of these autonomous systems is anticipated to take place in 2025, marking a significant milestone in the USAF’s efforts to revolutionize air-to-air refueling. As the technology matures and undergoes further testing and evaluation, the potential for widespread deployment across the USAF’s tanker fleet becomes increasingly promising.
