“These deliveries to our customer are significant for the THAAD program and Aerojet Rocketdyne,” said Michael Bright, vice president of Missile Defense and Strategic Systems at Aerojet Rocketdyne. “Fielding THAAD batteries for our troops and allies who are defending against the growing ballistic missile threat is a major focus for our customers. Meeting the growing demand for THAAD missile propulsion has been a major focus for Aerojet Rocketdyne. We look forward to continuing to provide affordable and reliable products for this unique missile defense capability that supports our nation and our allies."
