REPMUS 2026: Marble demonstrates Arctic-capable "ISR Bubble" system
UK company Marble demonstrated its remotely operated ISR Bubble at NATO’s REPMUS 2026 exercise in Portugal. The system combines a hangar with up to four unmanned aircraft that can be launched, recovered, and recharged without staff continuously present at the site; each aircraft has a stated operating radius of 250 kilometres. Designed from the outset for Arctic conditions, the concept is intended to monitor critical infrastructure from remote land sites, settlements near chokepoints, or ships. The demonstration showed the architecture, but operational endurance, sensor configurations, and procurement commitments remain customer-dependent.
