PurpleSector Feature in DSEI Gateway: Should Defence Embrace an F1™ Mindset?

The pace of change on the modern battlefield is exposing a growing mismatch between the speed at which threats evolve and the time traditionally required to develop and deploy new Defence capabilities.

In a new feature, DSEI Gateway explores what Defence can learn from the rapid iteration culture of Formula 1™, speaking with PurpleSector CEO and Founder Mark Mathieson MBE, and Senior Defence Advisor Gary Waterfall.

F1™ teams continuously design, simulate, test and improve complex systems throughout a racing season. Data gathered through digital twins, simulation and real-world testing creates a constant feedback loop, allowing teams to make informed engineering changes in weeks - or even days.

Much like Defence, every F1™ team has access to advanced tools, world-class engineers and significant investment - but what really differentiates performance is how quickly teams convert data into decisions. This requires authority to align with expertise, with decisions made by those who hold the greatest knowledge - enabling teams to respond quickly without losing valuable context.

Defence increasingly requires the same ability to iterate. Ukraine has demonstrated how short feedback loops between frontline operators and developers can allow technology to evolve in weeks rather than years. However, adopting this approach more widely will require a greater tolerance for managed risk, alongside a shift away from lengthy development cycles that seek perfection before capability reaches the user.

As Gary explained to DSEI Gateway, current approaches can focus too heavily on ensuring a capability performs in every possible scenario, rather than accepting proportionate risk to deliver systems more quickly and cost-effectively.

The principles behind this model have already been proven beyond motorsport. During the Covid-19 pandemic, Mark helped apply F1™-derived operating principles to the UK Ventilator Challenge, supporting the rapid redesign and scale-up of ventilator production within an extremely compressed timeframe.

The lesson for Defence is not simply to move faster. It is to create the culture, decision-making structures and feedback loops that make speed possible without losing control.

As Mark told DSEI Gateway:

“We’ve proven the impact of applying F1™ principles outside of F1™. It would be a mistake not to pivot that into defence.”
