Antigua-St.Kitts

Overview

Antigua-St.Kitts is a short intra-Caribbean submarine cable connecting Antigua and Barbuda with Saint Kitts and Nevis. Spanning just 14 kilometres, it is among the shortest systems in the Eastern Caribbean and provides a direct link between two neighbouring island nations in the Lesser Antilles.

Route and Landings

In Antigua and Barbuda, the cable lands at St. John's, the country's capital. In Saint Kitts and Nevis, it comes ashore at Basseterre, the capital of that island nation. The two landing points are separated by only 14 kilometres of open sea.

Ownership and Operators

Antigua-St.Kitts is owned by Liberty Networks, a regional telecommunications infrastructure provider operating across the Caribbean basin.

Status and Timeline

The cable entered service in 1995 and has now been operational for approximately 31 years, making it one of the longest-serving submarine systems in the Eastern Caribbean corridor.

Regional Context

Both Antigua and Barbuda and Saint Kitts and Nevis are each served by four submarine cables, with the first systems in both countries also dating to 1995. The Antigua-St.Kitts cable sits alongside several other systems that serve this corridor. The Eastern Caribbean Fiber System (ECFS), which also connects Antigua and Barbuda with Saint Kitts and Nevis and entered service the same year, is considerably longer at 1,730 kilometres, reflecting a broader multi-island route. Southern Caribbean Fiber, another system linking the same two countries, stretches 3,000 kilometres and became operational in 2006. The more recent Saba, Statia Cable System (SSCS), serving Saint Kitts and Nevis, runs 198 kilometres and reached service in 2013. The planned CELIA cable, landing in Antigua and Barbuda, is expected to be ready in 2027 and will extend some 3,700 kilometres. Against this backdrop, Antigua-St.Kitts stands out for its brevity and its focus on a single, direct inter-island connection.

Strategic Role

At 14 kilometres, Antigua-St.Kitts offers a dedicated, geographically direct submarine link between St. John's and Basseterre. Its short route and single-corridor focus distinguish it from the longer regional systems that span multiple islands and territories. For two small island nations with limited overland connectivity options, a direct submarine connection of this kind provides a straightforward path for inter-island communications between their respective capitals.
