In other words, he isn’t ready to commit to the Boeing-made E-7 Wedgetail, despite support from the service’s top general in the Asia-Pacific region. “I want to actually look at what options do we have,” Air Force Chief of Staff Gen. CQ Brown said during a Febl. 25 roundtable with reporters for the Air Force Association’s Aerospace Warfare Symposium. “It would be premature for me to commit to the Wedgetail right now, or a timeline. This is something I have to spend a little more time on looking at. But I realize there are some Wedgetail fans out there.”
