May 3/21: Pacific Edge A Royal Australian Air Force E-7A early warning aircraft flew to Hawaii for the inaugural exercise Pacific Edge last month. The E-7A were joined by F-22s from the Hawaii Air National Guard as blue force. The red force was played by F-16s from the 442nd Training and Evaluation Squadron. Seventeen F-22 pilots also flew inside the E-7A during the three-week exercise to provide real-time feedback to the E-7A on what is happening inside the F-22 cockpit during air-to-air engagements.

The island continent of Australia faces a number of unique security challenges that stem from its geography. The continent may be separated from its neighbors by large expanses of ocean, but it also resides within a potential arc of instability, and has a number of important offshore resource sites to protect. Full awareness of what is going on around them, and the ability to push that awareness well offshore, are critical security requirements.

“Project Wedgetail” had 3 finalists, and the winner was a new variant of Boeing’s 737-700, fitted with an MESA (multirole electronically scanned array) radar from Northrop Grumman. That radar exchanges the traditional AWACS rotating dome for the E-7A’s “top hat” stationary antenna. That design, and the project as a whole, have run into severe turbulence, creating problems for Boeing earnings, the ADF, and other export orders for the type. DID’s FOCUS articles offer in-depth, updated looks at significant military programs of record. This one covers contracts, events, and key milestones within Australia’s E-7A program, from inception to the current day.
