The House Armed Services Committee has voted to bar the Air Force from retiring a single E-3 Sentry AWACS aircraft through fiscal 2027. The amendment, introduced by Rep. Rob Wittman (R-Va.) and approved on June 4, extends a retirement freeze that has been in place since the fiscal 2026 defence bill — and sends a blunt message: Congress does not trust the Air Force to manage the transition from AWACS to its replacement. The vote came during a marathon markup of the fiscal 2027 National Defense Authorization Act, one of the most contentious defence bills in years. The E-3 provision was one of scores of amendments adopted, but its implications for the Air Force’s fleet strategy are among the most significant.

Why Congress Won’t Let Go

The Air Force has spent years arguing that the E-3 is obsolete. Its radar technology dates to the 1970s. Its airframe — a modified Boeing 707 — is increasingly difficult and expensive to keep airworthy. Mission-capable rates have been declining for years, and senior leaders have repeatedly said the Sentry cannot survive in a modern threat environment. All of that is true. But Congress keeps blocking retirements because the replacement is not ready. The Air Force contracted with Boeing to build the E-7 Wedgetail, a 737-based airborne early warning aircraft in service with Australia — the UK’s first aircraft arrived at RAF Lossiemouth in May 2026 and is still in test ahead of service entry. But the E-7 programme has faced delays, and lawmakers want a binding schedule before they let the Air Force retire anything. Wittman’s amendment requires the Air Force Secretary to produce a detailed procurement and fielding timeline for the E-7, including milestones for initial and full operational capability. It also demands certification that the transition will not degrade airborne early warning, battle management, or command and control capabilities that combatant commanders depend on.

The Saudi Arabia Factor

One detail in the amendment reveals the real-world pressure behind the numbers. The minimum fleet size has been lowered from 16 to 15 aircraft — almost certainly because one E-3 was catastrophically damaged in the Iranian missile and drone strike on a Saudi air base in March 2026. That attack, which also damaged other coalition assets, put a spotlight on just how thin the AWACS fleet has become. The Air Force recently deployed nearly 40% of its entire E-3 fleet to the Middle East for operations against Iran — a commitment that left other theatres exposed and underlined the risks of operating a fleet this small with no operational replacement in sight.

A Bigger Pattern

The E-3 freeze is part of a broader congressional revolt against Air Force retirement plans. The same markup session also voted to prohibit F-22 Raptor retirements through fiscal 2032. Lawmakers have consistently rejected the service’s attempts to divest legacy platforms before replacements reach operational maturity. The Air Force is requesting about $1.5 billion for the E-7 programme in fiscal 2027, a sign of how seriously it wants to accelerate the transition. But until Boeing delivers Wedgetails in numbers and the new aircraft proves itself in the demanding airborne battle management role, Congress intends to keep every flyable Sentry in service — however painful and expensive that may be.
