Classified U.S. RQ-180 Stealth Drone Suspected Landing at Greek Air Base in Rare Sighting

An unidentified stealth aircraft flew over Larissa, Greece, before landing near a key Hellenic Air Force base. Its configuration suggests a possible U.S. RQ-180 stealth drone, raising questions about ongoing classified ISR operations in Europe.
The aircraft was observed near the Hellenic Air Force’s 110th Combat Wing, a location frequently used for NATO and U.S. deployments. While initially mistaken for a B-2 Spirit, its wing profile, size, and apparent lack of a vertical tail diverge from known bomber characteristics. Analysts point instead to the highly classified RQ-180, a long-endurance, high-altitude stealth ISR platform believed to operate in contested airspace with advanced sensor payloads. No official confirmation has been issued by U.S. or Greek authorities.Read Also: Possible Appearance of Israeli RA-01 Drone Over Lebanon After Intelligence Leak

Photographs published on March 18, 2026, by the Greek outlet onlarissa.gr reveal a flying-wing configuration without vertical stabilizers, featuring a smooth geometry that clearly differs from the B-2, whose serrated trailing edge is absent. The aircraft also does not match the B-21 Raider, particularly due to the visible landing gear layout, nor the RQ-170 Sentinel, which is smaller and structurally distinct. The platform appears broader, with a wide wing and a pronounced central body, suggesting a design optimized for endurance and lift.
The observed configuration, especially the wide spacing of the main landing gear, indicates a large airframe capable of accommodating substantial internal systems. This supports the hypothesis of a High Altitude Long Endurance (HALE) platform, designed to operate above 50,000 feet, or approximately 15,000 meters. At such altitudes, it can cover wide areas while remaining outside the engagement envelope of many surface-to-air systems. The flying-wing design reduces radar cross-section by minimizing reflective surfaces and eliminating vertical structures.
The aircraft type most often associated with this architecture, known as the RQ-180, is attributed to Northrop Grumman under the Penetrating Intelligence Surveillance Reconnaissance (P-ISR) program. Although classified, it is generally described as a strategic intelligence platform combining low observability with long endurance. Estimates suggest a wingspan comparable to the RQ-4 Global Hawk, around 40 meters, with endurance exceeding 24 hours. Such a platform is expected to carry advanced sensors, including Active Electronically Scanned Array (AESA) radars capable of Synthetic Aperture Radar (SAR) imaging, along with electro-optical and infrared systems for persistent surveillance.
The images also show a slight bulge along the central fuselage, consistent with internal bays or sensor modules. However, the absence of visible air intakes or exhausts prevents any assessment of propulsion. On this type of aircraft, S-shaped intake ducts and shielded exhausts are typically used to reduce infrared signature. The aircraft appears dark in the images, whereas some descriptions refer to a lighter color scheme, which may be due to lighting conditions or coating variations.
The circumstances of the sighting remain unusual. The aircraft was observed in daylight with its landing gear deployed over a populated area, which does not align with typical operating patterns for a classified platform. According to local reporting, it may have diverted due to a technical issue, which would explain this exposure. Under normal conditions, such aircraft are expected to operate from remote bases or during time windows that reduce the risk of visual detection.
Larissa Air Base regularly hosts U.S. detachments, including MQ-9 Reaper operations. The MQ-9 Reaper, a Medium Altitude Long Endurance (MALE) drone, can remain airborne for more than 25 hours and carry multi-spectral sensors as well as precision-guided munitions, providing both surveillance and strike capabilities. The base infrastructure has been upgraded in recent years to support such operations, including facilities suitable for larger aircraft.
Flight tracking data also indicate that C-17 Globemaster III transport aircraft conducted multiple flights between Edwards Air Force Base in California and Larissa between February and March 2026. The C-17, capable of carrying more than 70 tonnes of cargo over intercontinental distances, is commonly used to deploy sensitive equipment. Edwards AFB, located near Palmdale where Northrop Grumman produces the B-21 Raider and previously built the B-2 Spirit, serves as a key hub for advanced aerospace programs. These movements may indicate logistical or technical support related to advanced systems.
The possibility that the aircraft could be an Israeli RA-01-type drone appears inconsistent with the available evidence. The observed proportions suggest a larger and more structurally complex platform than concepts attributed to that program. In addition, the operational and logistical context at Larissa aligns with an established U.S. presence. The daylight exposure of such a sensitive system would also be difficult to reconcile with the expected risk management practices of a clandestine Israeli program.
At this stage, the aircraft cannot be formally identified in the absence of official confirmation. However, the consistency between the observed features, the operational environment, and the available logistical indicators points toward a U.S. strategic intelligence platform of a new generation. The RQ-180 hypothesis remains plausible, but it should be treated with caution pending further evidence to clarify the exact nature of the aircraft observed.
