The US Air Force has started market research to find contractors capable of designing and delivering a suite of training devices for its future E-7 Wedgetail aircraft, according to a Request for Information (RFI) issued to industry.

The initiative comes as the E-7 is set to succeed the ageing E-3 Sentry as the service’s airborne warning and control platform.

Specifically, the Air Force is seeking industry feedback on the development, delivery, and ongoing support for an Operational Flight Trainer, two Virtual Maintenance Trainers, and a dedicated Training System Support Centre.

According to documents released by the US Government, the device development is expected to begin in 2027 or 2028, with long-term support anticipated beyond the systems’ delivery.

The RFI will gather information from potential suppliers; it does not constitute a formal request for proposals at this stage.

“The purpose of the E-7 Training Program is to provide the highest hands-on training experience for the E-7 flight crew and maintenance crew, to minimize aircraft training time,” the RFI document read.

This market research follows the Air Force’s 2022 selection of Boeing’s E-7 Wedgetail, a platform based on the 737 commercial airframe, as the replacement for the E-3 Sentry AWACS.

According to Air Force officials, the E-7 stood out as the only current aircraft able to meet the tactical battle management, command, and control requirements set by the Department of War.

The E-7 Wedgetail features a range of 3,500 nautical miles unrefuelled, a maximum ceiling of 41,000ft, and an Identification Friend or Foe (IFF) system with a range of 300 nautical miles.

The aircraft will operate with a total crew of 21, including two pilots.

Funding for the E-7 programme has seen several reversals in recent years. Although the Pentagon initially sought to remove E-7 procurement from the 2026 and 2027 budgets, Congress reinstated funding, a decision later confirmed by defence secretary Pete Hegseth in May.

Air Force Secretary, Troy Meink, told Congress that a $1.5bn budget amendment would restore E-7 Wedgetail funding for fiscal year 2027, with continued allocations for 2028 and subsequent years, including support for the first five production aircraft.
