Boeing Receives $10.9 Million Modification for VC-25B Test Maintenance

Boeing has received a $10.89 million U.S. Air Force contract modification to perform test maintenance work for the VC-25B presidential aircraft program, bringing the contract’s cumulative value to approximately $4.51 billion.

The modification, awarded to Boeing’s Tukwila, Washington, operation, covers VC-25B test maintenance at San Antonio, Texas. According to the contract announcement, the work is expected to be completed before flight testing, although the announcement does not specify a completion date or identify the individual maintenance tasks.

The award adds $10,889,535 to a contract whose value rises from $4,497,540,207 to $4,508,429,742. The Air Force Life Cycle Management Center at Wright-Patterson Air Force Base, Ohio, is managing the contract.

Maintenance work remains part of the aircraft development effort

The modification is separate from the program’s firm-fixed-price engineering and manufacturing development efforts. That distinction matters because the award is specifically associated with test maintenance rather than a disclosed expansion of the aircraft’s engineering and manufacturing development scope.

The Air Force is obligating $5 million in fiscal 2026 research, development, test and evaluation funds at the time of the award. This is the amount being committed initially, not the full value of the modification.

The contract announcement does not explain why the additional maintenance work is required, whether it addresses specific technical issues, or whether it changes the program’s overall schedule. It would therefore be premature to interpret the award as evidence of a new technical problem or a change in flight-test plans.

Why the VC-25B program matters

The VC-25B is the U.S. Air Force’s planned replacement for the existing VC-25A presidential aircraft. Based on Boeing’s 747-8 platform, the new aircraft are being modified to support presidential transportation and the communications and other mission requirements needed to operate as an airborne presidential command platform.

The Air Force’s Presidential and Executive Airlift Directorate oversees the program. Planned modifications include upgraded electrical power, mission communications, a medical facility, a specialized executive interior and a self-defense system, according to the Air Force Life Cycle Management Center’s program background.

The aircraft’s role makes maintenance, testing and certification essential parts of the acquisition process. Before a new presidential aircraft can enter service, its modified systems and airframe must meet applicable safety and mission requirements. The latest contract notice, however, does not detail which particular systems or components are covered by this maintenance award.

Contract value rises above $4.5 billion

The latest modification brings the cumulative face value of the contract to $4.508 billion. That figure represents the value of the contract after this modification, not the amount of money newly awarded for the current work.

Earlier contract activity also shows that the program’s spending extends beyond the original aircraft development work. In August 2026, the Air Force announced a separate $75 million modification for initial spare parts for the two VC-25B aircraft, bringing the contract’s cumulative value at that point to approximately $4.492 billion.

These awards cover different requirements. The spare-parts modification addressed initial logistics support, while the latest action funds test maintenance. Both illustrate that preparing the replacement aircraft involves more than modifying the airframes, with maintenance and support requirements also forming part of the program’s cost.

The cumulative contract value should not be confused with the final total cost of the entire presidential aircraft effort. The latest announcement does not provide a revised overall program estimate or a complete accounting of all associated government costs.

For now, the confirmed scope of the new award is limited: Boeing will conduct VC-25B test maintenance in San Antonio, with work expected to be completed before flight testing. The contract notice does not disclose further technical details or establish a new program milestone.
