Textron Systems has secured a $9.5 million contract to assist the US Air Force in evaluating a key defensive sensor installed on the F-15 Eagle.
The effort will center on the Eagle Passive Active Warning Survivability System (EPAWSS), which replaces the aircraft’s legacy radar warning receiver, internal countermeasures suite, and countermeasure dispensing systems.
To support this assessment, Textron will deliver several units of its proprietary Advanced Architecture Phase, Amplitude, and Time Simulator (A2PATS). This system is designed to evaluate radar warning effectiveness against advanced electronic warfare threats in dense operational environments.
The contract also includes benchmarking services and spare components alongside the testing systems. Work will be conducted in collaboration with the 68th Electronic Warfare Squadron at Eglin Air Force Base, Florida, over a 17-month period.
A portion of the program will also support evaluations for foreign military sales customers.
According to Textron, A2PATS enables realistic validation by generating waveforms typical of contested battlefields. The plug-and-play system accurately replicates signal phase, amplitude, and time of arrival across multiple frequency ranges, providing a high-fidelity testing environment.
