RAD Raises £4.4M to Scale Autonomous Vessel and Electric Propulsion

Marine technology company RAD has closed a 4.4 million pound funding round to accelerate the commercialisation of its autonomous vessel technology and expand its electric propulsion portfolio. The raise, led by Mercia Ventures, follows a period of strong commercial momentum that included the launch of Axon, the company's open systems architecture for uncrewed vessels. Proceeds will support international expansion, product development and engineering growth as RAD positions itself at the forefront of autonomous and electric marine innovation for defence and commercial markets.

 

Details of the Funding Round

 

RAD has completed a 4.4 million pound funding round to fund its next phase of growth. The raise follows a period of strong commercial and product momentum for the company. It was led by Mercia Ventures, signalling investor confidence in the business. The round reflects belief in RAD's ability to turn complex marine technology challenges into scalable products. This positions the company to pursue opportunities across both defence and commercial markets.

The investment builds on a year of significant achievements for the company. Over the past year, RAD has delivered major customer programmes and expanded its product portfolio. It also launched Axon, its open systems architecture for uncrewed and autonomous vessels. These milestones underpinned the confidence shown by investors in the round. The combination of commercial delivery and product innovation provided a foundation for the raise.

 

The Axon Systems Architecture

 

At the centre of RAD's recent progress is its Axon architecture. Axon is an open systems architecture designed for uncrewed and autonomous vessels. It was launched at the Combined Naval Event in Farnborough in May 2026. The launch generated significant interest from both defence and commercial organisations. This response demonstrated demand for flexible approaches to autonomous vessel development.

The architecture is designed to give operators greater flexibility and control. Axon enables boat builders and operators to rapidly develop, integrate and deploy uncrewed vessel capabilities. It allows them to maintain flexibility over their choice of autonomy and mission software providers. This helps operators avoid vendor lock-in throughout the life of their fleets. The open approach lets systems, autonomy software and mission applications evolve independently.

Strategic Priorities for the Investment

 

The proceeds will support several defined strategic priorities. A key focus is international expansion, with RAD having appointed its first US-based employee. The company is building its presence in key international markets beyond its home base. This geographic growth is intended to broaden the company's customer reach. It reflects an ambition to compete in the global market for marine technology.

Product and engineering development form the other central priorities. The funding will support continued development of RAD's electric propulsion systems and energy management technologies. It will also fund the commercialisation of the Axon architecture across the industry. In addition, the company plans to expand its applications engineering and delivery capability. This growth is intended to meet increasing demand from defence and commercial customers.

 

Market Context and Outlook

 

The investment reflects a broader shift anticipated in the marine sector. Investors drew a direct parallel with the electrification of road transport over the past decade. They expect the marine sector to undergo a similar transition toward electric propulsion. RAD is positioned as building the platform for this shift across both crewed and autonomous vessels. This framing places the company at the leading edge of an emerging market trend.

Company leadership sees autonomous marine systems moving rapidly toward deployment. RAD's co-chief executive noted that such systems are moving quickly from concept to real-world use. He argued that the industry is moving toward open, flexible vessel architectures. The funding provides the runway to scale commercially and expand into international markets. This positions RAD to deliver flexible, high-performance vessel systems for operators worldwide.
