Project Summary
The Type 45 Anti-Air Warfare Destroyers represent a critical element of the Royal Navy’s surface fleet, delivering advanced air defence capability well into the 21st century. As part of the initial outfitting programme, OCS, formerly FES FM and Support Services (“OCS”), was selected to deliver a future-proof fibre optic backbone infrastructure across the Type 45 class, supporting both immediate operational requirements and future technological advancement.
- 6 Type 45 destroyers (4 delivered by OCS) equipped with advanced optical fibre infrastuctures
- Future-proofed design for rapid communications upgrades
- Zero requirement for invasive cable replacement during lifecycle enhancements
- State-of-the-art blown fibre technology and ruggedised fibre cabling installed across full vessel infrastructure
Project Delivery
The Type 45 class, including HMS Daring, HMS Dauntless, HMS Diamond, HMS Dragon, HMS Defender, and HMS Duncan, are designed to provide unparalleled air defence, capable of tracking, engaging, and neutralising multiple airborne threats simultaneously. Protecting key Royal Navy assets such as aircraft carriers and amphibious task groups, the Type 45’s operational effectiveness is heavily dependent on resilient, high-bandwidth fibre optic infrastructure to support ship-wide communications systems.
Working in partnership with BAE Systems, OCS was responsible for the installation of a blown optical and ruggedised fibre network, tailored specifically to meet the demands of the Type 45. This innovative approach enabled the vessels to be equipped with state-of-the-art communications infrastructure from commissioning, whilst significantly reducing future disruption typically associated with system upgrades.
The blown fibre solution allows new fibre cables to be installed through pre-laid microducts using compressed air. This methodology provides exceptional flexibility, enabling rapid installation of upgraded or new systems without the need for structural modification or intrusive cable pulling activities.
Challenges
The unique operational environment aboard a warship necessitated a highly robust and adaptable network solution. Key challenges included:
- Navigating complex vessel geometries to provide comprehensive fibre coverage without compromising critical ship systems.
- Ensuring that the network design would accommodate both existing and yet-to-be-developed communications technologies.
- Delivering an installation that met stringent naval standards for durability, electromagnetic compatibility, and operational resilience.
OCS’s solution addressed these challenges through meticulous planning, extensive collaboration with BAE Systems and the Royal Navy technical authorities, and the deployment of specialist installation teams with significant maritime experience.
Collaboration and Partnerships
Successful delivery of the project was underpinned by close collaboration with BAE Systems, the prime contractor for the Type 45 programme. Regular interface meetings ensured alignment between communications infrastructure development and wider ship systems integration, supporting seamless project delivery within the broader shipbuilding schedule.
Results and Impact
The installation of a blown optical fibre network across the Type 45 destroyers has delivered substantial operational and strategic benefits:
Immediate operational readiness with a state-of-the-art communications system backbone infrastructure at vessel handover.
- Future-proofing of the communications system, with rapid, low-disruption upgrade capability embedded from day one.
- Reduced through-life costs by eliminating the need for major re-cabling works during technology refresh cycles.
- Enhanced resilience against evolving threats through the ability to rapidly integrate new systems and capabilities.
The blown fibre infrastructure continues to ensure that the Royal Navy’s frontline air defence platforms remain at the cutting edge of maritime communications technology, safeguarding operational superiority well into the future.
