MOD Projects - Project Darkstar

Overview

DARK STAR represents a foundational architectural concept and delivery programme that has established the technical baseline for cloud-based operations across the Royal Air Force's digital ecosystem. As an operational cloud architecture intended to reach across warfighting domains, DARK STAR has delivered the core hardware and software infrastructure that underpins contemporary RAF command and control capabilities, most notably the NEXUS digital C2 environment.

The programme delivered both the Air Cloud Hosting Environment (ACHE)—the physical hardware infrastructure—and the Air Information Platform (AIP), including visualisation tools that enable data fusion and decision-making. As a Defence Digital and ICT programme, DARK STAR established the technical and operational baseline that ensures compatibility, security, and support continuity for all subsequent RAF digital developments.

Strategic Vision and Objectives

Cross-Domain Cloud Architecture

DARK STAR's fundamental purpose is to provide an operational cloud architecture that spans across warfighting domains. This cross-domain approach breaks down traditional barriers between air, land, maritime, space, and cyber operations, enabling the integrated, multi-domain operations that characterise modern warfare.

Data Exploitation at Pace and Scale

The overarching goal for the RAF's use of cloud technology through DARK STAR is to enable an unsurpassed ability to consume, aggregate, analyse, and exploit data at both pace and scale. This capability is essential for maintaining information superiority and decision advantage in contemporary operating environments where the volume and velocity of data continue to increase exponentially.

Real-Time Sensor-to-User Information Flow

DARK STAR embodies an ambitious vision: to process data from every sensor on any platform in real-time, converting raw data into useful, flagged information that any authorised user can access and fuse with their existing knowledge. This sensor-to-user architecture represents a fundamental transformation in how military information systems operate, moving from platform-centric to truly network-centric operations.

Digital Resilience and Decision Superiority

The programme focuses on delivering digital resilience—ensuring that cloud-based capabilities remain available even in contested or degraded environments—and enabling rapid operational decision-making that provides decision superiority over adversaries.

Technical Architecture and Deliverables

Air Cloud Hosting Environment (ACHE)
