March 2/23: First USAF Deal Boeing won a $1.2 billion contract action for the E-7A Rapid Prototype program. This contract provides for the initiation of the development activities for the program. Work will be performed in Seattle, Washington, and is expected to be complete by August 2024. Air Force Life Cycle Management Center, Hanscom Air Force Base, Massachusetts, is the contracting activity. The E-7A Wedgetail “will provide advanced Airborne Moving Target Indication and Battle Management, Command, and Control capabilities, and advanced Multi-Role Electronically Scanned Array radar that enhances airborne battle management and enables long-range kill chains with potential peer adversaries,” the Air Force said. The E-7A was originally developed for Australia, and has also been adopted by the U.K. By leveraging allied investment in the E-7A, the US aims to acquire the new AWACS replacements more quickly than would otherwise be possible.

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.
