A specialist partner in defenceFor over 40 years the Ferranti name has been associated with prestigious defence programs such as Trident and Astute submarine, Warrior armoured fighting vehicle and the SA80 assault rifle.

Working collaboratively with UK MoD as prime contractor Denis Ferranti Limited are Design Authority for pyrotechnic signaling used on many of the Royal Navy frontline systems and by navies around the globe.

We understand the standards for mission critical equipment where robustness and reliability makes the difference between success and failure.

By adopting a concurrent engineering philosophy ‘in-house’ including software, electronics, mechanical design and systems integration, coupled to strong project management, lead time from concept to a fully tested, integrated solution is kept to a minimum.

Our Intellectual Property library for pyrotechnics is unique within the Defence industry, allowing us to react quickly to market requirements and offer reduced lead times whilst remaining compliant to customer specification and standards.

Products are manufactured at our 4,500 square metre facility in North Wales incorporating vertically integrated manufacturing from machining of components, through specialist painting, plating and test in accordance with MoD stringent quality standards.

    UK Trade & Investment

  • Denis Ferranti Group have provided MoD with a service that is technically competent and sound and one that offers good value for money.

    They have operated in a flexible, open and honest manner and are particularly customer-focused in their dealings with MoD and communicate well.

    Denis Ferranti Group are very pro-active in problem solving and in particular have presented a design solution to a critical safety defect identified in submarine distress signals that has provided a tangible reduction in the safety hazard to the Royal Navy Users.

    I have confidence in their design capability and management and I am in the process of transferring Design Authority ownership for a range of Naval stores from another contractor to Denis Ferranti Group and have confidence that they will fulfil their technical role in this key area well and offer MoD value for money.
