Autonomous Flight Termination Unit

The Autonomous Flight Termination Unit (AFTU) is a fully configurable termination unit which employs the latest software, technologies, and manufacturing processes providing a high performance, highly reliable, long-life product. The AFTU is fully compliant to all applicable RCC 319-19 specifications, without exception. The AFTU has no single-point failure and is remotely accessible for configuration and status monitoring.

The AFTU includes five customizable I/O banks with hardware or software cross-strapping providing maximum flexibility for every platform. Leveraging& decades of qualified flight termination, instrumentation, and range safety experience, the CAES AFTU is an extremely low SWAP unit, capable of handling the harshest operational environments.
