Persistent aerial surveilance below the clouds

With Kelluu, defense operations move with confidence. You see more details, decide faster, and protect your forces.

Modular platform for isr

Kelluu lifts your surveillance sensors higher, giving them extra reach and wider coverage. Electro-optical cameras, infrared, hyperspectral, radar, RF and comms payloads integrate on the same platform. The result is persistent aerial ISR across land, air, and maritime operations.

Turn low-altitude into your advantage

Satellites provide a wide global view, but intelligence loses accuracy with clouds and distance. Kelluu fixes this.

Our airships fly just below the clouds, between 50 and 1,000 metres (150 to 3,300 feet). They deliver accurate data and persistent monitoring. No one else provides long-duration intelligence in the low-altitude like this.

Operates where GPS fails

Kelluu navigates in GNSS-denied or jammed environments. Autonomous systems keep missions running in contested airspace.

Endurance in demanding environments

Airborne for up to 12 hours. Proven in Arctic conditions down to –30 °C (-22 °F). Airships can be set to patrol or loiter over areas of interest, offering persistence that drones and manned aircraft cannot match.

Remotely operated ISR

No pilot onboard. Controlled beyond visual line of sight. A reliable, low-risk way to maintain continuous surveillance over wide areas.

CASE: ATLANTIC TRIDENT 25

Kelluu at Atlantic Trident 25

Hosted by Finland, the exercise brought together the air forces of the US, UK, France, and Finland with over 40 aircraft and 1,000 personnel.

Kelluu provided persistent, silent aerial surveillance, complementing high-level intelligence with low-altitude precision data.
