Compare places

Two or three clusters, read side by side across sectors, research, companies, capital, infrastructure, government designations and UKIZ relevance. There is no score and no ranking: British clusters are different from one another, not better or worse than one another.

Companies	Not recorded on the map.	Glasgow small satellite manufacturing cluster	Bristol semiconductor and processor design cluster
Infrastructure	Not recorded on the map. Naval and maritime engineering facilities, photonics research centres and port infrastructure.	National Manufacturing Institute Scotland Satellite manufacturing capacity, nanofabrication cleanrooms and national manufacturing research facilities.	National Composites Centre Quantum and robotics laboratories, national composites facilities and aerospace test capability.
Capital	Prime contractor supply chain finance and public programmes rather than venture capital.	Public co-investment and specialist funds; hardware scale-up capital is scarce.	An established angel and seed base with strong deep tech interest; growth rounds usually come from London or the US.
Government programmes	Solent Freeport — Freeports	No place-based designation recorded.	No place-based designation recorded.
What exists	Maritime, naval and defence engineering, marine autonomy, photonics research and a major port and logistics complex.	More small satellites built here than anywhere else in Europe, quantum imaging and nanofabrication research, and a large applied engineering, manufacturing and energy research base.	Semiconductor and processor design, quantum engineering, robotics and autonomous systems, aerospace and composites, and a creative and screen economy of national significance.
What's missing · UKIZ interpretation	Routes for smaller innovators into defence and maritime procurement, and a civil market for capability developed for defence customers.	Downstream value. Satellites are manufactured here while much of the data and applications value is captured elsewhere. Scale-up finance for hardware is limited.	Fabrication and volume production capacity to match the design strength, and hardware-friendly capital. Companies scale by moving production abroad.
What could connect · UKIZ interpretation	Marine autonomy and photonics connected to Plymouth marine capability, Bristol robotics and offshore energy operations — the same technologies serving defence, energy and shipping.	Glasgow manufacture connected to Cornwall launch and Earth observation, Harwell space applications and domestic data customers — one national space chain instead of four regional ones.	Bristol design capability connected to South Wales compound semiconductor fabrication and to composites and aerospace manufacturing — a western technology corridor with a complete chain.
UKIZ relevance	Marine autonomy is where defence, robotics and clean energy meet. The proposed Cornwall & Devon marine mission connects to this capability directly.	Manufacture, launch and data are three different geographies in Britain. The proposed Scotland mission connects them deliberately.	Bristol's design and robotics capability has historically been acquired rather than scaled. The proposed zone concentrates on the capital and customer connections that let companies stay independent.
