The seeker deal aligns with an agreement in January between the Pentagon and Lockheed to up the annual production of THAAD interceptors from 96 to 400.
"It flies like a dream," ACC head Gen. Kenneth Wilsbach said of the new EA-37B Compass Call, a heavily adapted Gulfstream jet that will replace the EC-130.
The Air Force is planning to receive five EA-37B Compass Call electronic-warfare aircraft in 2025 as it moves forward with plans to retire its predecessor.
The Air Force's planned tests will make sure the new Compass Call's electronic warfare capabilities have been properly integrated into the Gulfstream jet.
