Platforms

Koios

Strategic ISR with a tactical footprint

Koios is our medium-sized, S2 Class, Vertical Take-Off and Landing (VTOL) platform, offering strategic ISR capabilities with a tactical footprint. Designed and manufactured in-house by Callen-Lenz, Koios is payload agnostic and is operationally proven in both civil and defence markets worldwide.

Key capabilities

Fregata

High endurance, long range ISR platform.

Fregata is a medium sized, S2 class, high endurance Conventional Take-Off and Landing (CTOL) ISR platform with an enhanced payload capacity. While Fregata requires more space to land than Koios it utilises lightweight skids that make short landings achievable on almost any surface. Like Koios, Fregata has been designed from the ground up in house by Callen-Lenz and has been tailored to suit long range missions where flight endurance is a priority.
