Digital Catapult has launched a nine-month accelerator that will fund up to 12 UK technology SMEs to develop digital-twin solutions against defined industrial challenges set by Artemis Technologies, BAE Systems, Thales and Vertical Aerospace.
Each successful company can receive up to £75,000 in Innovate UK grant funding alongside technical support, mentoring, access to specialist facilities and direct contact with the organisation that set its chosen challenge. Applications opened on 15 September and close on 27 October, with the programme due to begin in February 2027.
The Digital Twin Industry Challenge Led Accelerator is being delivered through the UK Digital Twin Centre and is structured around four specific engineering problems rather than generic technology demonstrations. They span marine situational awareness, aircraft system health, uncrewed-vessel monitoring and real-time support for eVTOL flight testing.
Artemis Technologies is asking participants to develop systems capable of detecting small objects above and below the waterline in complex marine environments. The challenge combines real-time sensing, edge computing and digital-twin technology, including operation where communications bandwidth may be restricted.
BAE Systems has set a different problem around in-service aircraft. Participating SMEs will be asked to develop and validate a digital twin for either an actuation or fuel system, with the aim of improving condition monitoring, predictive maintenance and fleet-management decisions while generating information that can inform future aircraft designs.
Thales is targeting health monitoring for uncrewed surface vessels. Remote operation increases the value of knowing the condition of onboard equipment because a technician may not be physically present when faults develop. The challenge therefore requires digital-twin systems that can combine sensor information, identify abnormal behaviour and support decisions about the appropriate response.
Vertical Aerospace is focused on development rather than through-life operation. Its challenge calls for a digital shadow capable of running alongside eVTOL test flights, using modelling, simulation and live data to generate predictions and identify approaching limit conditions for telemetry and flight-test engineers.
The structure addresses one of the persistent difficulties around industrial digital twins: establishing a sufficiently valuable use case. Manufacturers and engineering companies can build detailed models of assets, but a model only becomes operationally useful when the information changes a maintenance, testing, production or control decision.
Digital Catapult is effectively placing that requirement at the front of the programme. Applicants must bring a demonstrable technology or capability to an existing industrial problem and show that it can create measurable value, rather than develop a platform first and search for an application later.
That should also make the resulting proof-of-concept work easier to assess. A BAE Systems project can be judged against its ability to represent aircraft-system behaviour and support maintenance decisions; a Vertical Aerospace project can be assessed against whether it improves the speed or quality of decisions during testing. The outcome is more concrete than simply demonstrating that data from a physical asset can be reproduced digitally.
Interoperability, data quality and integration remain substantial constraints. Industrial assets typically combine equipment from several suppliers, existing control systems and historical data sets that were not created with a digital twin in mind. A useful twin therefore has to work with the information available rather than assume a clean-sheet digital environment.
The accelerator provides SMEs with direct access to challenge owners partly to address that issue. Understanding how data is generated, which interfaces can realistically be accessed and what decisions engineers are trying to make can alter the architecture of a proposed solution before significant development time is spent.
The UK Digital Twin Centre is backed by more than £37 million of investment over five years through public funding and industry co-investment. It is intended to move digital-twin technology through a progression from understanding and validation towards practical deployment, with industrial partners already involved in aerospace, maritime and defence use cases.
For the participating SMEs, the attraction is not limited to grant funding. Working against a named industrial requirement gives smaller technology companies a route to prove systems in environments where access can otherwise be difficult, particularly in aerospace and defence where qualification, security and integration requirements can create high barriers to entry.
The programme is due to conclude with a showcase in October 2027. By then, the useful measure will not be the number of visual models produced but whether the projects can influence real engineering decisions. The four challenges provide clear tests: detecting hazards, identifying deteriorating equipment, supporting fleet maintenance and making aircraft testing more informed in real time.
If the accelerator produces systems that survive those requirements, Digital Catapult will have moved the discussion beyond whether digital twins can be built. The more relevant industrial question is whether they can be trusted sufficiently to alter how complex physical assets are designed, tested and maintained.
