Tech giant Meta has announced plans to deploy a 50,000-kilometre undersea cable system spanning five continents to enhance global data transmission and support the increasing demand for artificial intelligence (AI) applications.

The massive infrastructure project—dubbed Project Waterworth—will connect major regions, including the United States, South Africa, India, and Brazil, aiming to strengthen international connectivity and facilitate economic cooperation and digital inclusion.

Meta disclosed this initiative in a blog post on Tuesday but did not provide a timeline for the project’s completion.

Expanding the Backbone of the Internet

According to Meta, global digital communication relies heavily on undersea cables, with approximately 1.2 million kilometres of submarine infrastructure already installed worldwide, as noted in a 2024 report by the US-based Centre for Strategic and International Studies (CSIS).

“These cables form the backbone of internet infrastructure, carrying vast amounts of data across continents,” the company said.

The new high-capacity fibre-optic cable aims to support AI-driven services and cloud computing by enhancing global data transfer speeds.

The Role of Project Waterworth

Meta emphasized that Project Waterworth would enable:
✅ Faster and more reliable data transmission
✅ Expansion of digital services in developing markets
✅ Economic growth and digital transformation in key regions

“For example, in India, where we’ve already seen significant growth and investment in digital infrastructure, Waterworth will accelerate progress and support the country’s ambitious plans for its digital economy,” Meta stated.

Next-Gen Subsea Cable Technology

Undersea cables are made up of multiple fibre-optic strands encased in armoured sheaths to protect them from environmental damage. Many are buried several meters beneath the seabed for additional security.

Meta highlighted its ongoing infrastructure innovations, stating:

👉 More than 20 subsea cable projects have been developed over the past decade.
👉 New cables will feature 24 fibre pairs, compared to the 8–16 fibre pairs found in typical systems.

A Race to Improve Global Connectivity

Meta’s investment in subsea cables aligns with its strategy to expand internet access, AI applications, and cloud computing services worldwide. The project places Meta alongside other tech giants, including Google and Amazon, in the race to enhance global digital infrastructure.

With AI and data-heavy applications becoming more prevalent, investments like Project Waterworth are expected to shape the future of global communication and digital economies.
