Congress has stepped in to block the Pentagon from canceling a troubled and expensive military aircraft program—tying the hands of President Donald Trump’s Defense Department as it attempts to rein in costs and modernize America’s war-fighting capabilities.
Lawmakers moved to preserve funding for Boeing’s E-7 Wedgetail surveillance aircraft, despite years of delays, rising price tags, and growing questions about whether the system will remain effective in future conflicts.
A High-Cost Aircraft Under Fire
Reporting from The Wall Street Journal describes the E-7 as a long-range surveillance aircraft capable of spotting airborne threats far beyond the horizon, staying aloft for lengthy missions, and directing large-scale air combat operations.
The aircraft is built on a modified Boeing 737 airframe and was intended to replace the Air Force’s aging E-3 Sentry planes—some of which have been in service for nearly 50 years.
But the replacement effort has been anything but smooth.
Initial estimates placed the cost of each Wedgetail prototype at about $588 million. That figure later ballooned to roughly $724 million per aircraft, triggering concern inside the Pentagon as delays mounted and budgets tightened.
Pentagon Sought Cancellation
Earlier this year, Pentagon leaders announced plans to cancel the purchase of two Wedgetail prototypes. Officials pointed to cost overruns, schedule problems, and the rapid advancement of space-based surveillance technologies that could eventually replace some airborne missions.
Defense officials also raised concerns about whether large, slow-moving aircraft would remain survivable in a future conflict against near-peer adversaries.
Congress Steps In
Congress reversed the Pentagon’s decision in the newly enacted $901 billion defense policy bill.
Senate lawmakers blocked any attempt to terminate the Wedgetail program and added $847 million in funding for the two aircraft. At the same time, they ordered the Air Force to address affordability issues and submit a plan to reduce costs and streamline requirements.
War Secretary Pete Hegseth testified before House lawmakers in June that the department must carefully reevaluate expensive platforms that may not perform well in future high-end conflicts. He also warned that space-based systems could soon outperform certain traditional airborne assets.
Boeing Pushes Back
Boeing maintains that the United States will ultimately need a balanced approach, combining both aircraft and satellite systems to ensure reliable global surveillance.
The Wedgetail carries a Northrop Grumman–designed radar mounted on the aircraft’s body, features ten mission workstations, and can remain airborne longer than legacy surveillance planes.
Allies Rethink the Program
The U.S. is not alone in reassessing the Wedgetail.
The Netherlands recently abandoned plans to acquire the aircraft for NATO missions. The United Kingdom scaled back its planned purchase from five aircraft to three. Australia, the original customer, is moving forward with upgrades to its existing fleet rather than expanding it.
Air Force Caught in the Middle
The Air Force says it will comply with the defense law while seeking cost savings, including completing portions of the aircraft modification work in Britain, where operators already have experience with the platform.
Despite the controversy, Air Force commanders insist that replacing the E-3 Sentry fleet remains unavoidable. Aging aircraft, growing maintenance challenges, and shrinking spare-parts availability continue to strain readiness—leaving the service caught between congressional mandates, cost control, and the push to prepare for future wars.
