Meta launches ambitious global submarine cable project

Tuesday 18 February 2025 - 14:34

Meta has announced plans to deploy a 50,000-kilometer submarine cable connecting five continents to enhance global digital data capacity and reliability. The initiative, named Project Waterworth, is the company’s most ambitious submarine cable endeavor to date.

The cable aims to provide high-performance connectivity to regions including the United States, India, Brazil, South Africa, and others. Meta has confirmed that the project represents a multi-year, multi-billion-dollar investment.

Submarine cables are crucial infrastructures that support nearly all global digital communications. According to an August 2024 report from the Center for Strategic and International Studies (CSIS), approximately 450 cables spanning 1.2 million kilometers currently connect the world’s oceans.

While the submarine cable market has traditionally been dominated by four companies—SubCom, Alcatel Submarine Networks, NEC, and HMN Technologies—tech giants like Meta are increasingly investing in their own networks due to the growing economic importance of digital connectivity.

Despite their strategic role, submarine cables are vulnerable to damage from natural events such as landslides and tsunamis, as well as from ship anchors. Additionally, they can be targets for sabotage or espionage. With the rapid advancement of artificial intelligence and generative models, which require vast amounts of data, global digital traffic is expected to surge in the coming years.
