Footage from a recent Ukrainian strike on a Russian oil refinery captured an unidentified drone resembling the US F-117 Nighthawk stealth jet, though on a far smaller, drone-sized scale, according to RBC-Ukraine. Online observers suspect a new Ukrainian jet-powered strike drone, or a test of an allied foreign one, but no official body has confirmed what the aircraft is. If the guesses hold, Ukraine may be fielding a faster, longer-reaching class of weapon for hitting targets deep inside Russia.

Ukraine has spent the past year turning Russia's interior into contested space, sending long-range drones ever deeper toward the oil, defense, and logistics sites the Kremlin once treated as untouchable. Each new type that surfaces marks another step from short-range drones toward missile-like machines.

An unfamiliar silhouette over the refinery

The drone appeared during a 2 August Ukrainian drone strike on a refinery near Ufa, more than 1,300 kilometers from the Ukrainian border. The clip shows an aircraft shaped unlike most Ukrainian long-range drones, likely powered by a jet engine. The open-source monitoring channel Clash Report, which first shared the footage, believes it may be the Bravo drone or a modified version.

What the Bravo could do, and why it would matter

If the aircraft is indeed a Triada Robotics product, the company describes Bravo as a single-use, jet-powered drone intended for long-range strike missions. According to the developer, its range exceeds 2,000 km (about 1,240 miles)—enough to reach much of the refinery and defense-industrial infrastructure Russia keeps far from the front lines.

Triada Robotics says the drone cruises at about 600 km/h and can accelerate to roughly 800 km/h (around 500 mph) during the final phase of flight. The company also lists a warhead weighing more than 100 kg (220 lb), a payload that could threaten facilities such as fuel depots or refineries.

The developer pitches it as a cheaper stand-in for a cruise missile—long-range reach at a fraction of the cost—so Ukraine could fly more strikes at distant targets.

Why observers compare it to the F-117

The comparison rests on the drone's silhouette. Watchers noted its outline echoes the F-117 Nighthawk, the US jet built with radar-evading shaping. A similar shape, though, does not prove full stealth. Such geometry can also sharpen aerodynamics or dodge only certain radar types. Even so, the aircraft's identity stays unconfirmed, and its edge rests on the maker's claims rather than proven use.

Russia has shifted its scarce fleet of A-50U airborne radar aircraft to near-daily operations, according to an analysis by Ukrainian OSINT channel Cyberboroshno. After barely flying against Ukraine for most of June, the aircraft are now patrolling almost nightly to detect Ukrainian drones, operating from airfields deep inside Russia and, on 7 July, four were airborne at once—almost the country's entire combat-ready fleet.

From barely flying to daily duty

For most of June, Russia hardly sent its A-50U airborne radar planes up against Ukraine, according to Cyberboroshno. Its analysts studied more than 1,600 reports between 4 June and 2 August. Early in that window, the only real activity involved a repaired aircraft, tail number Red 47, returning to service.

That changed on 23 June, when one plane began patrolling over Russia's interior above Ulyanovsk and Samara oblasts, mostly at night. Those flights continued for the rest of the period, roughly 60 sorties in all. Basing later shifted deeper into the rear, from Ivanovo and Ulyanovsk to airfields near Perm, Orenburg, and Chelyabinsk. On 7 July, Russia put four A-50U planes in the air at once—close to its entire combat-ready fleet.

Ukraine's missiles are what's driving the surge

Russia's ground defenses struggle to catch Ukraine's long-range cruise missiles, so airborne radar helps spot them early. On 4 July, Cyberboroshno said an A-50U played a decisive role in helping repel one such Ukrainian missile strike.

Why every one of these planes matters

The A-50U is Russia's flying radar—an airborne command post that scans the sky for hundreds of kilometers and guides fighters and missiles. Ukraine shot one down over the Sea of Azov on 14 January 2024, and says it downed the second over Russia's Krasnodar Krai on 23 February 2024. 

Russia entered its all-out war with fewer than ten of these aircraft in service, and the only plant that builds and maintains them has since slid into deep losses, with a strike destroying the prototype of the successor meant to replace them. A single A-50U can track aircraft and cruise missiles out to 700 km. Every sortie forced by Ukraine’s attacks eats into the aircraft’s limited flight life and risks a plane Russia cannot replace.
