Since 2023, Anduril UK has experienced rapid growth, introducing world-leading software-first, hardware-enabled systems to the UK Ministry of Defence and other government agencies. Our exemplar programme of Maritime Sentry Towers (MST), has been developed and delivered in close partnership with the UK government and sovereign British industry, fundamentally changing how border security and surveillance capabilities can be employed by UK authorities. Additionally, Anduril UK has expanded its portfolio to include the ALTIUS-600, a versatile autonomous aerial system, and Seabed Sentry, an advanced underwater surveillance platform. These systems, along with others, position Anduril UK to provide a broad range of software and software-enabled hardware products to meet the UK's defence and security needs as outlined in the 2023 Integrated Review Refresh and Defence Command Paper. World-leading technology like MST, ALTIUS-600, Seabed Sentry, and many of the other autonomous systems that will underpin the UK's technological future rely on modern C4 systems. These systems can integrate and fuse data across distributed systems, nodes, and networks to enable timely command decision-making. Anduril's open architecture Lattice operating system is an AI-powered software platform that transforms thousands of data streams into actionable information for operators at all levels. As the world enters an era of strategic competition, Anduril is committed to bringing cutting-edge autonomy, AI, computer vision, and networking technology to UK defence and security personnel in months, not years. Our focus is on rapidly delivering innovative solutions that enhance the UK's defence capabilities, support its industrial strategy, and contribute to its position as a science and technology leader.
