Blue Arrow Defense Launches RII, a C2 System for Multi-Drone Operations in Contested Environments
Kyiv, Ukraine & Pittsburgh, PA— 2 April 2026 — Blue Arrow Defense, a U.S.–Ukrainian defense technology company, today announced the launch of RII, a next-generation command-and-control (C2) system designed to enable coordinated multi-drone operations in GPS-denied and communications-contested environments.
Born out of frontline operational demands, RII introduces a scalable command layer that allows to plan large scale missions while a single operator can manage multiple drones and missions simultaneously shifting drone operations from isolated missions to coordinated, operational-level execution.
RII provides a unified control and management across heterogeneous drone fleets, agnostic to any UAS system. The system enables operators to plan, execute, and adapt complex missions in real time from a single interface.
“RII is not just about swarming—it introduces a command layer on top of drone operations,” said Sergii Tereshchenko , CEO of Blue Arrow Defense. “We build products that directly support warfighters and deliver immediate operational impact. Operating in Ukraine gives us a firsthand understanding of the realities and demands of asymmetric warfare.”

From Single Flights to Coordinated Missions
RII enables a new operational model where multiple drone classes (ISR, bomber, and strike UAS) work together as part of a unified mission. For example, ISR drones can be deployed across multiple directions to map and monitor the environment, while strike and FPV platforms execute targeted actions based on continuously updated intelligence.

As missions unfold, gathered data from ISR drones feeds back into RII, generating a dynamic, real-time representation of the battlefield that supports rapid replanning and adaptive execution.
To enable rapid deployment, Blue Arrow pairs RII with MZK (“Mozok,” Ukrainian for “brain”), a compact onboard hardware module that carries core autonomy and mission software directly onto the drone. This module integrates:
-
GPS-independent visual navigation
-
Onboard object detection and tracking
-
Fleet coordination and mission logic
-
Terminal guidance and ballistic computation modules

These capabilities are designed to reduce operator workload allowing a single user to safely manage multiple drones under conditions of electronic warfare and communications degradation.
Deployment and Availability
Blue Arrow Defense will initially deploy RII and MZK as an integrated solution with Ukrainian defense units, enabling rapid field testing and iteration in real-world conditions.
