Defence Holdings PLC (LSE: ALRT), the UK's first listed software-led defence company, is pleased to announce that it has completed a binding Strategic Partnership with Whitespace Global Limited ("Whitespace"), a leading UK deep-technology company specialising in AI infrastructure for defence, national security, and regulated public sector operations.
The agreement formalises the framework for Defence Holdings and Whitespace to co-develop a portfolio of defence-focused software applications and AI agents on Whitespace's proprietary Collective OS platform, with the first builds for the UK Ministry of Defence and allied partners already underway.
Key Highlights
● The partnership's first AI product is already under development for the UK Ministry of Defence. While details remain part of an operationally classified programme, it represents a commercially significant opportunity with long-term deployment potential.
● Already engaged with one of the world's leading technology providers to accelerate deployment timelines and support scalability.
● Framework to co-develop a portfolio of sovereign AI applications on Collective OS for high-priority defence and national security use cases.
● Defence Holdings to invest in initial AI capability builds, securing long-term commercial upside through a revenue share and structured cost recovery on deployment.
● Applications to deliver operational advantage in mission-critical domains, including autonomous decision-making, secure intelligence fusion, multi-domain situational awareness, protection of critical national infrastructure, and information domain dominance, encompassing both information and disinformation warfare.
● Joint IP ownership with flexibility to spin out projects into Special Purpose Vehicles for broader allied deployment, with Defence Holdings retaining majority control.
● Creates one of very few UK-listed platforms with the infrastructure, operational traction, and capital market access to challenge foreign incumbents and establish a sovereign AI leader in defence technology.
