BAE Systems has completed final hardware component deliveries of its Compass Call airborne EW jammer for the new EC-37B aircraft.
The first upgraded Baseline 3 Compass Call airborne standoff EW jamming system aboard USAF EC-37B aircraft will include ‘key components’ from BAE Systems, the company announced on 21 September.
BAE Systems stated that it has delivered final Baseline 3 hardware in preparation for initial flight tests in January 2023.
Baseline 3 offers additional EW capabilities and BAE Systems expects it to be fielded on an interim basis from mid-2024 while work continues on the Baseline 4 configuration.
The EC-37B is a new platform for Compass Call, as BAE Systems has provided the system for USAF EC-130H aircraft since 1981.
The EC-37B is based on the Gulfstream G550 commercial business jet. The EC-37B programme began in FY2017 with an estimated procurement cost of $1.45 billion for ten aircraft, according to Shephard Defence Insight.
There are 13 EC-130H aircraft in USAF service with an expected retirement date of 2025.
