It took losing an E-3 Sentry over Iran to make the Pentagon do what it should have done years ago. Secretary of Defense Pete Hegseth has submitted a budget amendment to the White House adding funding for the E-7A Wedgetail to the fiscal year 2027 budget request — reversing a decision made just months earlier to defer the programme. The loss of an aging AWACS aircraft during Operation Epic Fury apparently concentrated minds. The E-3 Sentry fleet has been in crisis for years. The aircraft — based on the Boeing 707 airframe — entered service in 1977. The average airframe is approaching 50 years old. Readiness rates have been abysmal: at times, fewer than half the fleet has been mission-capable. The Air Force has been trying to retire the E-3 and replace it with the E-7 Wedgetail — a modern airborne early warning platform based on the Boeing 737 — but budget fights kept pushing the timeline to the right. Then one of them was shot down.

A Loss That Changed the Conversation

The details of the E-3 shootdown remain partially classified, but the aircraft was operating in support of strike packages over Iran when it was engaged by Iranian air defences. The E-3’s role — orbiting at high altitude, providing the radar picture that directs fighters and bombers to their targets — made it a high-value target. Its loss immediately degraded the coalition’s ability to coordinate complex air operations in the theatre.

The loss also exposed a hard truth: the E-3 fleet was already too small and too old to sustain wartime operations. With one fewer aircraft, the remaining Sentries were pushed harder, and readiness — already below 50 per cent on some days — became even more precarious.

What the E-7 Brings

The Wedgetail is not just a newer AWACS — it is a fundamentally more capable platform. Its MESA (Multi-role Electronically Scanned Array) radar provides 360-degree coverage without the E-3’s iconic rotating dome, which creates mechanical reliability problems and blind spots during rotation. The E-7’s radar is electronically steered, meaning it can track multiple threat sectors simultaneously and switch modes in milliseconds. Australia has operated six E-7s since 2012 and considers them a generation ahead of the E-3. Turkey, South Korea, and the United Kingdom have also ordered the type. The Royal Air Force took delivery of its first E-7 in 2025, debuting it at RIAT — an ironic footnote given today’s cancellation of that same airshow.

The Budget Reversal

Earlier this year, the Pentagon’s budget request had deferred significant E-7 funding, pushing the programme further to the right. The decision was widely criticised by Air Force leadership and members of Congress, who argued that the E-3’s declining readiness made delay unacceptable. The Iran war changed the math. The budget amendment submitted by Hegseth does not detail the exact funding level, but it signals that E-7 procurement will be accelerated rather than stretched. The Air Force has previously estimated it needs at least 26 E-7As to replace its E-3 fleet. For a programme that has spent years stuck in budget purgatory, losing an E-3 in combat was the grim catalyst that finally broke the logjam. The Wedgetail is coming — the only question now is how fast. Sources: Air & Space Forces Magazine, Defense News, The Aviationist
