Bober / Beaver / UJ-26

A compact selection from this profile, with sources and limits. Other configurations and additional measurements remain in the full profile.

Full profile and archive

A Ukrainian long-range one-way aircraft reported under the Bober/Beaver name. Espreso publishes a specification table; the Prytula Foundation independently lists Bober in its procurement programme. Procurement acknowledgement does not verify the published performance figures.^[1][2]

Public-source profile. Performance claims are attributed; type links do not verify an incident identification.

Schematic top view of the general configuration. Not to scale and not an exact depiction of the model.

Form, sound & identification limits

All six measurements share one reporting origin, Espreso’s table. They are reported specifications, not independently replicated tests or a guaranteed combination of maximum range, speed and load.^[1]
The characteristic canard layout is background description, not proof that every similar object is Bober. The foundation’s indexed procurement list adds programme context; neither source automatically creates an incident tag.^[1][2]

Shape or sound alone cannot identify a drone. Follow local public-safety alerts; do not approach wreckage.
