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.	Not recorded on the map.	Glasgow small satellite manufacturing cluster
Infrastructure	Not recorded on the map. Naval and maritime engineering facilities, photonics research centres and port infrastructure.	Space and Earth observation capability, Cornwall Aerodrome and space capability, marine research and test facilities and naval infrastructure.	National Manufacturing Institute Scotland Satellite manufacturing capacity, nanofabrication cleanrooms and national manufacturing research facilities.
Capital	Prime contractor supply chain finance and public programmes rather than venture capital.	Public programmes and a small local investor base; almost all growth capital is external.	Public co-investment and specialist funds; hardware scale-up capital is scarce.
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.	Space launch and Earth observation capability, marine autonomy and ocean research, and a distinctive combination of coastline, test space and specialist facilities.	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.
What's missing · UKIZ interpretation	Routes for smaller innovators into defence and maritime procurement, and a civil market for capability developed for defence customers.	Company density and connectivity. Excellent facilities sit a long way from capital, customers and complementary suppliers, and skilled people are hard to retain.	Downstream value. Satellites are manufactured here while much of the data and applications value is captured elsewhere. Scale-up finance for hardware is limited.
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.	Launch and Earth observation connected to Glasgow satellite manufacture and Harwell applications, and marine autonomy connected to Solent defence and offshore energy demand.	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.
UKIZ relevance	Marine autonomy is where defence, robotics and clean energy meet. The proposed Cornwall & Devon marine mission connects to this capability directly.	The proposed Cornwall & Devon mission treats the sea and the satellite economy as one system rather than two separate sectors.	Manufacture, launch and data are three different geographies in Britain. The proposed Scotland mission connects them deliberately.
