U.S. B-1B bombers, F-15E Strike Eagles and F-35A Lightning IIs flew together over the North Sea during Astral Knight 26, in imagery released by DVIDS on June 11, 2026, demonstrating how U.S. airpower combines strike aircraft, advanced sensors and command networks into a single operational force. The formation shows how bomber firepower, fighter escort, stealth-enabled awareness and aerial refueling can be integrated to support NATO air defense and long-range strike operations across Europe.
The exercise highlights a combat model in which the F-35A expands situational awareness, the F-15E adds multirole firepower, and the B-1B delivers heavy conventional strike capacity at range. Backed by tankers, electronic warfare support and tactical command and control, Astral Knight 26 demonstrates how U.S. forces are preparing to operate across contested airspace where endurance, networking and rapid transitions between defensive and offensive missions are critical.

The U.S. Defense Visual Information Distribution Service released on June 11, 2026, imagery showing U.S. Air Force B-1B Lancer bombers, F-15E Strike Eagles and F-35A Lightning IIs flying together during Astral Knight 26 over the North Sea. The formation, supported by aerial refueling operations, offers a visible demonstration of how U.S. airpower combines bomber aircraft with fourth- and fifth-generation fighters in a networked combat environment. In the context of Europe’s evolving air and missile threat landscape, the image is not only a display of aircraft readiness but also a signal of how modern air operations are built around integration, endurance, tactical command and control, and the ability to shift rapidly between defensive and offensive missions.
Astral Knight 2026, led by U.S. Air Forces in Europe-Air Forces Africa under U.S. European Command, is designed as a high-end integrated air and missile defense exercise. Conducted from the United Kingdom, it involves U.S. Air Force personnel, F-35A Lightning IIs and F-15E Strike Eagles from the 48th Fighter Wing at RAF Lakenheath, as well as KC-135 Stratotankers from the 100th Air Refueling Wing at RAF Mildenhall. The use of these home-station assets is operationally relevant because it reflects how U.S. forces based in Europe could generate combat airpower from established air bases while supporting NATO air defense missions across the northern and western approaches to the continent.
The presence of bomber aircraft and fourth- and fifth-generation fighters in the same aerial formation gives the image a broader operational meaning. Rather than a simple flypast, the B-1B, F-15E and F-35A combination reflects the composition of a modern composite air package, in which different platforms provide complementary effects within the same mission architecture. The B-1B Lancer brings long-range conventional strike capacity and payload volume, enabling the delivery of effects at operational depth. The F-15E Strike Eagle adds a multirole fighter-bomber profile suited for escort, interdiction and precision attack, while the F-35A Lightning II contributes low-observable penetration, sensor fusion, electronic situational awareness and tactical data-sharing. Together, these aircraft illustrate how modern airpower is no longer based solely on individual aircraft performance, but on the ability to connect sensors, shooters and command nodes across a contested battlespace.
This mixed-generation formation also highlights the tactical value of integrating fourth- and fifth-generation aircraft. In a high-end air operation, the F-35A can act as a forward sensing and information-sharing platform, using its sensor suite and low-observable design to improve situational awareness and support the wider air package. The F-15E can carry a larger weapons load and operate as a strike, escort or interdiction asset, while benefiting from targeting and threat information shared through secure data links. The B-1B, although not a stealth aircraft, remains relevant in such a package because of its range, speed and ability to deliver significant conventional payloads once access, routing and threat suppression have been managed. This combination shows how readiness is measured not only by the number of available aircraft, but by their ability to operate as a coordinated force.
Aerial refueling is central to this operational model. By extending the range and endurance of combat aircraft, tanker support allows fighters and bombers to remain on station for longer periods, sustain defensive counter-air patrols, support offensive counter-air missions and conduct long-range strike profiles beyond the limits of unrefueled operations. In Astral Knight 26, tanker tracks and refueling windows help preserve tempo during live-fly vulnerability periods, allowing aircraft to maintain formation discipline, manage ingress and egress routes, and remain available for follow-on tasking. For operations over the North Sea and across the European theater, this endurance is critical because air defense missions may require aircraft to respond to simulated cruise missile threats, adversary aircraft, or land-based targets at extended distances from their launch bases.
The exercise also demonstrates how integrated air and missile defense depends on the ability to transition from defensive to offensive air operations. Astral Knight 26 begins with defensive combat air missions against simulated adversary jets and cruise missiles, directly reflecting the need to protect allied airspace from airborne and missile threats. The training then shifts to offensive combat air missions, including sweep, escort, suppression of enemy air defenses and air interdiction against simulated air and land-based targets. This sequencing is important because modern air defense does not end with interception. To reduce the threat over time, air forces must also be able to disrupt enemy aircraft, sensors, surface-to-air missile systems, launch infrastructure and command networks that enable offensive operations.
Tactical command and control is another key element behind the formation. The 606th Air Control Squadron from Aviano Air Base provides Tactical C2 during live-fly operations, ensuring that aircraft are synchronized and that the air package can respond to changing threat conditions. Its rapid mobility mission, simulating a deployed environment, adds a further layer of operational realism by testing whether battle management and control functions can be moved, established and sustained outside fixed infrastructure. In a European conflict scenario, where air bases, radar sites and communication nodes could be targeted, the ability to disperse and rapidly reconstitute command-and-control capacity would be essential for maintaining air operations.
Electronic warfare support from the 19th Electronic Warfare Squadron adds another technical layer to Astral Knight 26. By deploying land-based emitters to simulate adversary surface-to-air missile threats and by providing Link 16 network simulations, the squadron helps create a realistic electromagnetic environment for aircrews. Spectrum deconfliction ensures that simulated jamming and threat replication do not interfere with civilian infrastructure, while technical signal analysis and mission reconstruction allow commanders and crews to assess simulated engagements in detail. This makes the exercise not only a flight training event but also a test of the wider kill chain, from detection and tracking to data exchange, targeting, threat response and post-mission assessment.
The B-1B, F-15E and F-35A formation over the North Sea during Astral Knight 26 sends a clear operational message: modern airpower depends on integration, not isolated platform capability. Bomber aircraft and fourth- and fifth-generation fighters flying together show how the U.S. Air Force is preparing to combine strike mass, fighter escort, low-observable sensing, aerial refueling, electronic warfare and tactical command and control into a single combat system. In a European security environment shaped by cruise missile threats, contested airspace and electromagnetic warfare, Astral Knight 26 demonstrates that readiness is defined by the ability to connect aircraft, crews, networks and command structures at speed. The formation therefore stands as both a training milestone and a deterrence signal, showing that U.S. air forces in Europe are preparing to defend allied airspace while retaining the capacity to conduct offensive operations if deterrence fails.
