The F-15 Eagle Passive/Active Warning and Survivability System (EPAWSS) upgrade for the US Air Force (USAF) has passed its Critical Design Review (CDR), it was announced on 1 May.

The EPAWSS EW suite will replace the legacy TEWS system that has been fitted to F-15C (pictured) and F-15E-variant Eagles since the 1980s.

The programme prime, Boeing, completed its CDR of the system in February following a review of the CDR of the system's electronic warfare (EW) suite that was undertaken by sub-contractor BAE Systems in late 2016.

EPAWSS is designed to sample the radio frequency (RF) spectrum, identify threats, prioritise, and allocate jamming resources against them, and will replace the 1980s-vintage Tactical Electronic Warfare Suite (TEWS) currently fitted to the USAF's more than 400 F-15C and F-15E-variant Eagles.

Boeing was awarded a USD478.8 million contract for the engineering, manufacturing, and development (EMD) of EPAWSS in November 2016. With the CDR now passed, aircraft modification and flight testing will begin. As noted by BAE Systems, the programme is running about a month ahead of schedule. The system should be ready for operational fielding by 31 August 2020.
