The UK-Ukraine technology-sharing arrangement announced in September 2025 created a route for Ukrainian designs and battlefield-driven updates to be produced in Britain. The first named project was Project OCTOPUS, an advanced air-defence interceptor drone intended for mass production in the UK, with government statements describing a target of thousands of drones per month.
Public sources identify two distinct UK facility contexts relevant to weapon production. One is the UK production line for the Octopus interceptor drone, supported by a Ukraine-UK licensing agreement and later UK government statements that production had started. The other is Ukrspecsystems' East Anglia footprint: GOV.UK identified Mildenhall and Elmsett sites for a factory plus testing and training facility, while Ukrainian reporting described the launch of a UK plant for Ukrspecsystems drone production.

Public sources describe the UK production arrangements at programme, facility, or company-site level and do not identify every subcontractor, production-line operator, or component supplier. The narrow UK facilities scope is limited to sourced UK-based production contexts rather than a legal manufacturer name.
