Delivering mission-ready UAS capabilities anywhere in the world

Since 2008, Callen-Lenz has been delivering internationally recognised UAS operations from military ISR missions to infrastructure and environmental surveys. We have consistently pioneered the use of commercially operated UAS in new and innovative ways.

We deliver a full spectrum of operational requirements on a ‘capability as a service’ basis. Our teams support customers in planning, commissioning, air traffic integration and executing complex operations across the globe. This approach provides scalable, repeatable, advanced UAS capabilities without needing in-house expertise.

Our teams have a genuine passion and extensive knowledge of aircraft operations, with expertise ranging from rotary to fixed wing aircraft across civil and military applications. The operational expertise of our personnel enables us to develop and deliver safe and effective solutions and services in some of the most challenging environments and circumstances.
