Evidence & current status
Current and older manufacturer figures differ. The current table is labelled explicitly and not retroactively applied to older Ukrainian deliveries.
RQ-35 Heidrun is Sky-Watch's compact reconnaissance platform. Current supplier material describes hand launch, deep-stall recovery and a 3.35 kg maximum take-off configuration. The manufacturer also documents Ukrainian military use, which is retained as attributed operator evidence.
The current platform page and earlier brochure do not describe an identical numerical baseline. The older sheet lists 3.05 kg and contains differing endurance statements within the same document. The present table is used for the displayed current figures rather than averaging the publications or selecting whichever value appears strongest.
A family name can persist while aircraft, batteries or mission equipment change. A purchaser or researcher therefore needs the configuration and publication date alongside each comparison. The recorded maximum flight time is not a guaranteed mission duration, and transmission reach is not total flight distance. Exact customer configurations and independent performance validation remain separate evidence questions.
