U.S.A.F.’s New Combat Rescue Helicopter Finishes Developmental Tests Our Bureau 404 HH-60W combat rescue helicopter The U.S. Air Force’s new combat rescue helicopter, the Sikorsky HH-60W Jolly Green II, completed developmental tests earlier this week. Tests were conducted at Eglin Air Force Base on April 13, the service announced today. The final test by the Sikorsky and Air Force team was on the aircraft’s weapon systems. The goal of the test was to both demonstrate the performance of the weapons while optimizing weapon-system configurations. The HH-60W first flew in May 2019. The aircraft arrived at Eglin AFB to the 413th FLTS November 2019, although various tests took place in other locations. The integrated test team accumulated more than 1,100 flight test hours across six aircraft testing the full spectrum of aircraft systems.
