These are exciting times in British aerospace. I want to talk you through Proteus, the UK’s bold leap into large-scale uncrewed rotorcraft for the Royal Navy. And yeah—I’ll weave in silver. The shimmer of innovation deserves a metaphor, and silver fits snug in the naval technology of today/future.
A Decade of Foundation—Now Slated for a Metallic Takeoff
Leonardo’s journey with the UK Ministry of Defence isn’t new—it’s over ten years in the making. This trajectory gave birth to Proteus, part of the RWUAS Phase 3A Technology Demonstrator Programme, a four-year, £60 million commitment awarded in July 2022. Proteus, a ~three ton c3t rotorcraft, is being designed, developed, and built at Yeovil. Its first flight is planned for mid 2025.
This isn’t smoke and mirrors—Proteus is strategic, modular, autonomous. It stands as a crucial element of the Royal Navy’s Maritime Aviation Transformation (MATx), a vision stretching toward 2040.
Why Autonomy Matters Now More Than Ever
This isn’t just tech for tech’s sake. Budget cuts, personnel challenges, and a hostile global climate all press hard on the Royal Navy. Autonomy, AI, drones—they’re not buzzwords—they’re strategic multipliers. As the UK’s Strategic Defence Review recently outlined, “drones, AI and autonomy” are integral to a hybrid of conventional and digital warfighters.
Autonomous platforms like Proteus pack endurance and focus—no humans on board, so you ditch crashworthiness tailored to people, seats, displays, and cut complexity and cost. Imagine grey North Atlantic nights, pounding seas, endless submarine searches. Proteus offers persistent coverage while human crews rest ashore—a silent, unblinking sentinel.

Milestones in the Mirror: Synthetic Demonstrations Spark Trust
Let me pause and reflect—seeing really is believing. In July 2024, Proteus ran its first synthetic “ASW FIND” mission: locating and classifying a simulated submarine autonomously. Then by May 2025, objective-based automatic mission planning kicked in: multi-aircraft task handover, wide-area surveillance, sensor fusion (EO, radar, AIS), feeding real-time tactical data to ship combat systems.
These tests are the silver sheen that reflects real-world promise. Not theoretical—they’re real-time, multi-asset, AI-coordinated maneuvers.
SILVERWARS
Silver in the Skeleton: Where the Shine Gets Real
From avionics to actuators, the Proteus isn't just about cutting-edge autonomy—it’s also packed with materials that make that autonomy possible. Silver’s role? Everywhere the mission can’t afford to fail:
| Component Area | Silver Application Example |
| High-voltage connectors | Silver-coated contacts for efficient, low-resistance power transfer |
| Avionics bay EMI shielding | Silver-infused mesh/fabrics to reduce interference and data corruption |
| Heat sinks and cooling pathways | Silver-filled thermal interface materials (TIMs) for edge computing and AI hardware |
| Aerospace fasteners and joints | Silver-plated threads to prevent galling, corrosion, and ensure durability in salt-air missions |
| Radar and sensor antenna systems | Silver coatings and conductive pastes for high-frequency signal fidelity |
| Redundant onboard power systems | Potential silver-zinc or silver oxide batteries for autonomy-critical payloads |
Autonomy doesn’t just need code; it needs conductivity, cooling, and corrosion resistance. That’s where silver, with its unmatched properties, comes in.

Final Design Unveiled—On the Verge of Flight
Early 2025 brought the final design reveal. Proteus takes cues from the AW09 helicopter, with a five-blade main rotor, modular fuselage, and autonomy baked in. It’s designed for large maritime UAS viability, flight control laws, and autonomous VTOL systems.
And it debuted at DSEI 2025 in London—a clear message of intent. A fully modular, autonomous, large-scale UAS—capable of ASW, ISR, logistics—isn’t just rad. It’s high-value tech, envisioned in silver precision.

Beyond Proteus: A Strategic Silver Forged Gem
Once it flies, Proteus will be activated in live tests, deck landings, harsh North Atlantic conditions. But its purpose is larger: refining how uncrewed rotorcraft integrate into the Navy’s structure. It’s a stepping stone toward mass at sea operations under MATx. And the export potential? Allies eyeing modular autonomy will see this as a beacon.
Proteus isn’t just hardware. It’s an investment in sovereignty, UK industry, and operational innovation—a silver thread weaving through strategic autonomy.
