• US Space Force awards $615 million for space-based aircraft tracking.
• Contracts awarded to Rocket Lab, Systems & Technology Research, and a third undisclosed company.
• Program aims to provide persistent surveillance of airborne targets from orbit.
• Space-Based Air Moving Target Indicator programme is part of broader Space-Based Sensing and Targeting portfolio.

The US Space Force's investment in space-based aircraft tracking may indicate a shift towards more persistent and comprehensive surveillance capabilities. This could suggest a growing concern about aerial threats and the need for enhanced battlespace awareness, which may have significant implications for the development of future military operations and strategies.
