Kennith Osborne, 780th Test Systems Squadron guns and missiles flight engineer, conducts a visual inspection of PGU-9D/B 40 millimeter cartridges at Eglin Air Force Base, Fla. The 780th Test Squadron guns and missiles test flight developed a safe method to repurpose 80,000 of the WWII-era rounds with upgraded, safer fuzes. The unit successfully tested the refused cartridges on the Eglin range this summer. Modernized PGU-9D/B rounds are presently and exclusively used on AC-130U gunship aircraft.
