Ilyich, Russia

Ilyich, Russia: Submarine Cable Landing Point

Ilyich is a landing point located in Russia, situated on the coast in a position that places it at the western end of the Kerch Strait corridor. Two submarine cables make landfall here, connecting Ilyich to Ukraine across the narrow stretch of water that separates Russia and Ukraine in this region. The cables landing at Ilyich represent a short-haul, cross-strait connection rather than a long-distance intercontinental link, reflecting the geographic proximity of the two countries at this particular coastal crossing.

The two cables at Ilyich — the Kerch Strait Cable and the Energy Bridge Cable — both terminate in Ukraine on their opposite ends, establishing a bilateral submarine link between the two countries. This configuration makes Ilyich a dedicated bilateral terminus for Russia-Ukraine connectivity across the Kerch Strait, a notably compact corridor by the standards of submarine cable infrastructure.

Cables Landing at Ilyich

The Kerch Strait Cable is a 46-kilometre submarine cable that reached ready-for-service status in 2014. It connects Ilyich, Russia with a landing point in Ukraine, spanning the Kerch Strait in a relatively short undersea route. The cable was assigned a draft status at the time of its documentation.

The Energy Bridge Cable is a 13-kilometre submarine cable that reached ready-for-service status in 2017. Like the Kerch Strait Cable, it connects Ilyich, Russia with Ukraine, making it one of the shortest submarine cables associated with this landing point. It too carries a draft status in its documentation. At just 13 kilometres, it ranks among the shorter submarine cable deployments in the region.

Regional Context

Within Russia's network of 28 submarine cable landing points, Ilyich sits alongside several two-cable landing points including Anadyr, Nahodka, Petropavlovsk-Kamchatsky, and Sovetskaya Gavan, each of which also host two cables. Ilyich is therefore representative of the mid-tier landing points in Russia by cable count, hosting more than single-cable sites such as Amderma and Dikson. What distinguishes Ilyich from most of its Russian peers is the exclusively bilateral, short-range nature of both its cables, as opposed to the longer international routes served by other Russian landing points.

Network Role

Ilyich functions as a two-cable terminus specifically oriented toward cross-strait connectivity with Ukraine. Both cables — the Kerch Strait Cable and the Energy Bridge Cable — serve this single bilateral corridor, meaning the landing point does not branch toward multiple countries or intercontinental routes. The combined route lengths of its two cables, 46 kilometres and 13 kilometres respectively, are far below Russia's average submarine cable length of 4,510 kilometres, underscoring the highly localised role Ilyich plays within the broader submarine cable graph.

In the regional submarine cable graph, Ilyich represents a specialised short-haul node that provides direct undersea connectivity between Russia and Ukraine across the Kerch Strait, a function that is distinct from the longer-haul and more geographically diverse connectivity offered by other Russian landing points.
