R Baker (Electrical) Ltd has completed the final shipset of transformers for the Type 31 programme, marking a significant milestone for our business. As a UK SME operating within the defence supply chain, delivering this final shipset demonstrates our ability to support complex naval programmes to completion.
This achievement reflects long-term investment in engineering capability, controlled manufacturing processes, and close collaboration with programme partners. The delivery further strengthens our position as a trusted UK supplier supporting modern naval defence projects.
Supporting the Type 31 Programme at Rosyth
The Type 31 programme represents a major investment in the Royal Navy’s future surface fleet. Reliable electrical infrastructure is essential to ensure safe operation, system resilience, and long-term platform availability throughout service life.
Since 2020, we have worked alongside Babcock International at Rosyth to manufacture and supply Ship Set 5 transformers. Units ranged from 15kVA to 250kVA and were engineered to meet strict onboard space, performance, and integration requirements.
UK Naval Shipset Transformers for Demanding Marine Environments
Each transformer was designed specifically for naval operating conditions. Efficiency, resilience, and compact design were prioritised to support installation within constrained shipboard environments. These factors are critical to maintaining performance and reliability at sea.
All UK naval shipset transformers were subject to structured inspection and testing prior to delivery. Electrical performance was verified against customer specifications, ensuring consistent operation under continuous load and variable operating conditions.
Engineering Transformers for Defence Applications
Designing transformers for defence use requires careful consideration of electrical, mechanical, and environmental stresses. Equipment must withstand vibration, shock loading, and prolonged exposure to marine conditions without compromising performance.
Our engineering approach addressed thermal stability, electrical integrity, and mechanical robustness from initial design through manufacture. This disciplined process reduced programme risk and supported reliable installation and long-term operational performance.
Standards Compliance and Lloyd’s Register Approval
All transformers were designed in accordance with DEF STAN requirements and applicable UK transformer regulations. Compliance was assessed against customer technical specifications and programme standards throughout the project lifecycle.
Independent approval was achieved through Lloyd’s Register. Certification confirmed that marine safety, performance, and construction requirements were fully met. This process required controlled documentation, manufacturing oversight, inspection, and witnessed testing.
UK Naval Shipset Transformers – Documentation and Quality Control
Defence programmes demand comprehensive documentation and full traceability. For the Type 31 programme, TES and GTR-aligned records were supplied covering the design, manufacture, inspection, testing, and certification of UK Naval Shipset Transformers.
Quality assurance was integrated throughout production, with inspections conducted at defined stages. Any non-conformances were managed through controlled procedures, supporting audit readiness and long-term in-service support.
Leadership and Collaborative Delivery
The project was led by Gareth Baker, providing consistent technical oversight across design, manufacture, and delivery. Engineering focus and delivery discipline were maintained throughout the programme.
Close collaboration with Babcock International enabled effective communication and timely decision-making. This approach supported early risk identification and ensured alignment with programme requirements at each stage.
