LOSSIEMOUTH, SCOTLAND — May 22, 2026 : The first Boeing E-7 Wedgetail Airborne Early Warning and Control (AEW&C) Mk1 aircraft for the Royal Air Force (RAF) arrived at RAF Lossiemouth on May 21, 2026, marking a major milestone in restoring the United Kingdom’s long-range airborne surveillance and battle management capability.
The aircraft, registered WT001, flew from STS Aviation Services at Birmingham Airport to its future permanent operating base in Scotland. The flight was conducted by a mixed crew of Boeing UK and RAF personnel. On arrival, the aircraft was welcomed by Group Captain Sarah Brewin, Station Commander at RAF Lossiemouth, representatives from Boeing UK, the Wedgetail Project Team, No. 8 Squadron personnel, and members of the RAF Lossiemouth Pipe Band.
The arrival marks the beginning of the aircraft’s final Test and Evaluation phase before formal entry into RAF service later in 2026. Testing activities will take place at both RAF Lossiemouth and MOD Boscombe Down in Wiltshire, the UK’s primary military aircraft testing facility. The programme is intended to verify the aircraft’s radar, communications, mission systems, and operational performance before formal handover from Boeing UK to the RAF.
Once testing is completed and the aircraft achieves its planned Initial Operational Capability (IOC), WT001 will transition into operational service with No. 8 Squadron, the RAF unit that previously operated the Boeing E-3D Sentry fleet for more than three decades.
The E-7 Wedgetail programme is replacing the RAF’s retired E-3D Sentry airborne warning aircraft, which were withdrawn from service in 2021 due to rising maintenance costs and aging airframes. The remaining E-3D aircraft were later sold to Chile in 2022. During the capability gap, NATO allies, particularly the United States and other alliance partners, supported the UK’s airborne early warning requirements.
Advanced Radar and Mission Systems
The E-7 Wedgetail is based on the Boeing 737 Next Generation commercial airframe. WT001 itself is a converted Boeing Business Jet originally delivered in 2010.
The aircraft is equipped with the Northrop Grumman Multi-Role Electronically Scanned Array (MESA) radar, mounted in a fixed dorsal rotodome on the fuselage spine. Unlike older airborne warning aircraft that rely on mechanically rotating radar dishes, the MESA radar uses electronically steered beams to provide simultaneous multi-sector coverage.
The radar is capable of tracking hundreds of airborne and maritime targets across long distances while providing commanders with a real-time operational picture. According to programme data, the system can detect fighter-sized targets at ranges exceeding 400 kilometres in look-down mode and more than 850 kilometres in look-up conditions at altitude.
The aircraft is also fitted with secure communication systems including UHF, VHF, HF, SATCOM, and Link 16, along with electronic support measures and ten operator mission consoles. These systems allow the platform to coordinate missions involving RAF Typhoon and F-35 combat aircraft, tanker fleets, intelligence and surveillance assets, and naval forces operating in joint environments.
RAF Lossiemouth’s Strategic Role
RAF Lossiemouth was selected as the main operating base for the Wedgetail fleet because of its strategic location on the northeastern coast of Scotland, providing rapid access to the North Sea and North Atlantic approaches. These areas remain important monitoring corridors for NATO due to regular Russian long-range aviation activity near alliance airspace.
The station already hosts RAF Typhoon fighter squadrons and a fleet of nine Boeing P-8 Poseidon maritime patrol aircraft. Since both the Poseidon and Wedgetail are based on the Boeing 737 Next Generation airframe, the RAF and Boeing plan to use common maintenance infrastructure, spare parts logistics, and technical expertise across the two fleets.
New engineering, maintenance, and squadron facilities have also been constructed at Lossiemouth to support the Wedgetail programme and future operational activities.
Programme Background and International Operators
The UK originally signed a contract in 2019 to procure five E-7 Wedgetail aircraft, though the order was later reduced to three aircraft during the 2021 Integrated Review as part of wider defence cost-saving measures. However, the 2025 Strategic Defence Review indicated that future fleet expansion remains under consideration.
The programme also experienced schedule adjustments due to aircraft integration and conversion work. WT001 was formally unveiled in RAF markings in October 2024 before entering the current testing phase.
The E-7 platform already has an established operational history internationally. It entered service with the Royal Australian Air Force in 2009 and is also operated by the Republic of Korea Air Force and the Turkish Air Force. In 2022, the United States Air Force selected the E-7 as its future airborne early warning aircraft to replace portions of its aging E-3 Sentry fleet.
Official Statements
Group Captain Sarah Brewin stated:
“We are delighted to welcome the arrival of the first Wedgetail aircraft to RAF Lossiemouth to continue its Test and Evaluation phase. This marks a significant step in delivering the Royal Air Force’s next generation of airborne surveillance and control capabilities that will support the defence of the UK for the years to come.”
Stu Voboril, Boeing E-7 Vice President and Program Manager, said:
“The E-7 will provide the UK with the world’s most advanced, capable and reliable Airborne Early Warning and Control platform, while supporting British industry through UK jobs and supply chain opportunities.”
The RAF expects the E-7 Wedgetail to deliver long-range airborne surveillance, battlespace management, target tracking, and coordination of fighter, tanker, intelligence, surveillance, and reconnaissance assets once the aircraft formally enters service later in 2026.
