The seL4 Foundation thanks Collins Aerospace [0] for becoming a sponsor of the seL4 Summit 2025. Collins Aerospace has generously sponsored the seL4 summit every year since 2023. Collins Aerospace [0], part of seL4 Foundation member RTX [1], has been a long-time core participant in the seL4 ecosystem. Collins was a prime contractor in the DARPA HACMS program which demonstrated the seL4-based incremental cyber retrofit of autonomous military vehicles. This was a major milestone in the growth of seL4, demonstrating that it protects against cyber attacks on real systems in operation. The same team also led the follow-on DARPA CASE program, aiming at designed-in cyber-resiliency, including the seL4-based framework for verified initialisation and configuration of systems architectures. Collins Aerospace is now leading a team on the DARPA PROVERS program which has a goal of enhancing the security of defense and aerospace systems by dramatically improving the usability, flexibility, and accessibility of formal methods-based development and verification tools, and targeting seL4 as an implementation platform.
