Saltcoats is a town on the west coast of North Ayrshire, Scotland, situated along the Firth of Clyde. As a coastal settlement, it serves as a landing point for submarine cable infrastructure connecting parts of the United Kingdom. One submarine cable lands at Saltcoats: the Sirius North cable, which links locations within the United Kingdom.
Because both endpoints of the Sirius North cable are within the United Kingdom, Saltcoats functions as part of a domestic submarine cable corridor rather than an intercontinental or interregional one. This places it in the category of intra-national submarine cable infrastructure, serving connectivity within the UK rather than bridging separate national territories.
The Sirius North cable is the sole submarine cable landing at Saltcoats. It has a length of 147 kilometres and reached ready-for-service status in 1999, with a draft status noted for the route. Both of its endpoints are located within the United Kingdom, making it a domestic cable linking two points on British coastline. No further technical specifications regarding capacity or fiber configuration are recorded for this cable.
Within the United Kingdom's submarine cable network — which spans 66 cables across 125 landing points — Saltcoats hosts a single cable, placing it in the top 88 percent of UK landing points by cable count. Compared to more heavily served landing points such as Bude (8 cables), Lowestoft (6 cables), and Blackpool (4 cables), Saltcoats represents a smaller-scale node in the national submarine cable landscape. Its peers Broadstairs, Porthcurno, and Southport each host three cables, further illustrating the relatively modest scale of Saltcoats as a landing point.
Saltcoats operates as a single-cable terminus within the UK's domestic submarine cable network. The Sirius North cable, at 147 kilometres, connects two points within the United Kingdom, enabling intra-national submarine connectivity from this location on the west coast of Scotland. It does not serve as a hub for multiple cable systems, nor does it anchor an international or intercontinental corridor.
Within the broader submarine cable graph of the United Kingdom, Saltcoats represents a focused, single-purpose landing point that contributes to domestic network resilience by extending submarine cable reach to the Scottish west coast — a coastline that, without such infrastructure, would remain less integrated into the country's undersea cable topology.
