UK to lead development of AUKUS undersea sensor payloads

The Ministry of Defence has announced the UK will lead the development of three advanced sensor payloads for uncrewed underwater vehicles. The systems are designed to detect threats and protect infrastructure, and will be available to UK, Australian, and US fleets from 2027.

The Ministry of Defence has confirmed that the UK will lead the development and delivery of three specific sensor payloads for uncrewed underwater vehicles. This initiative forms part of the AUKUS partnership between the UK, Australia, and the United States. The payloads are intended to collect underwater information, detect threats, and generate underwater effects to protect infrastructure.

Minister for Defence Readiness and Industry Luke Pollard stated: "The UK is all in on AUKUS, and this cutting-edge technology shows why." Under the plans, the systems will be available for use by the UK, Australia, and the United States starting in 2027. The announcement follows testing and demonstrations conducted at the Maritime Big Play exercise in San Diego.

British companies in Frome, Basingstoke, and Dorchester are involved in the work, creating skilled jobs. This project is the first signature project under AUKUS Pillar 2, which aims to pool defence innovation. No specific limitations or additional conditions were stated in the announcement.
