Also known as
  • Nyan OWE
  • Nyan one-way effector

Nyan is a British low-observable one-way effector UAV developed by Callen-Lenz under BAE Systems' FalconWorks umbrella. Public reporting connects the turbojet-powered air vehicle to a combat debut in Ukraine, British Army deep-fires service, and launch integration with Threod's CATA B catapult.

Design And Service Context

Nyan sits in the low-cost one-way-effector tier rather than a recoverable reconnaissance-UAV family. Aviation Week describes a carbon-fiber air vehicle with more than 150 km range, UK assembly, and domestic component sourcing where possible.

Development driver

Callen-Lenz began the design in 2022 after UK requirements emphasized payload, speed, and price point for an expendable strike air vehicle.

British service route

The February 2026 UK MoD notice said the Nyan OWE had already been tested, assured, and purchased by the Army before wider Field Army introduction.

Payload growth

Callen-Lenz's chief executive told Aviation Week the airframe could potentially accept other payloads, different warheads, or scaled range and endurance variants.

Launch System

Public reporting connects Nyan to Threod's CATA B launcher for British Army one-way-effector operations.

Callen-Lenz says Nyan was fielded alongside the Estonian-built CATA B launcher at Exercise Spring Storm, and Aviation Week reports that Nyan was combined with a Threod-supplied catapult.

Public sources identify it as part of Ukraine's domestically developed deep-strike inventory, with direct official reporting placing RS-1 Bars in the May 2026 Moscow-region strike package and later defense reporting describing a Bars RS variant with a larger fuel tank, higher takeoff weight, and 1,000 km class use claims.

Open sources treat it as a previously little-known Bars-family weapon, so the record separates the confirmed Ukrainian conflict-use claim from family-level range, payload, speed, and manufacturer details that remain only partly disclosed.

Open sources describe it as a pusher-propeller, canard-layout loitering munition with roughly 800 to 1,000 km of reported range, an approximately 20 kg warhead, and later catapult-launched examples, giving Ukraine an indigenous strike option for targets far beyond the front line.
