IOKWE

IOKWE: what this cable is

IOKWE is a planned submarine fiber-optic cable system for the Republic of the Marshall Islands (RMI). The project was publicly announced in March 2026: the Marshall Islands National Telecommunications Authority (NTA / MiNTA) said the country was joining Google's Pacific Connect initiative and building a new cable that will connect RMI directly to Google's Halaihai system.

The name "Iokwe" carries several meanings in Marshallese: "hello", "love", and figuratively "rainbow / you are beautiful as one". In the NTA release it is framed as a symbol of connection, unity, and the country's "digital handshake" with the world.

The key idea: IOKWE is not a standalone trans-Pacific cable spanning thousands of kilometers, but a national branch system, an offshoot that connects the Marshall Islands to Google's larger Halaihai trunk.

Geography and landing points

According to available data, IOKWE will connect the Marshall Islands to the Halaihai trunk, which is part of the central-Pacific portion of Google Pacific Connect. DatacenterDynamics reports that the full details and timeline for IOKWE have not been disclosed, but Submarine Networks lists expected landings at Majuro and Ebeye.

These are important points:

• Majuro is the capital of RMI and the country's main administrative and economic center.
• Ebeye / Kwajalein Atoll is a critically important population and infrastructure hub, next to the U.S. Ronald Reagan Ballistic Missile Defense Test Site on Kwajalein Atoll; it is already historically tied to the HANTRU-1 cable.

The existing HANTRU-1 cable already links Guam, Kwajalein, Majuro, and Pohnpei, but it remains effectively the only international submarine backbone for RMI. Geographically this is an extremely difficult territory: the Marshall Islands consist of 29 coral atolls, 5 main islands, and more than 1,000 small islands spread across a vast expanse of the Pacific Ocean.

How IOKWE connects to Halaihai

Halaihai is one of Google's new cables under Central Pacific Connect. In January 2024 Google announced two new intra-Pacific systems: Bulikula, linking Guam with Fiji, and Halaihai, linking Guam with French Polynesia. According to Submarine Networks, Halaihai is to connect Guam and the CNMI / Northern Mariana Islands with French Polynesia and Chile, with an estimated length of about 17,483 km.

Google has described Central Pacific Connect as an architecture that forms a "ring" between Guam, French Polynesia, and Fiji, with pre-placed branching units so that other Pacific nations and territories can connect to this infrastructure. IOKWE fits exactly into this logic: the Marshall Islands are not building a huge trans-Pacific trunk of their own, but obtaining a sovereign branch into Google's large system, using a "trunk and island system" model.

Architecture: the "trunk and island system"

In public statements IOKWE is described as a "trunk and island system" project: there is a large backbone cable (the trunk, in this case Halaihai) and a national branch (the island/branch) that is owned and operated by the local side. In practice this means:

• Google builds and owns the large trans-Pacific Halaihai infrastructure, which provides enormous capacity and international connectivity.
• RMI, through NTA, gets its own IOKWE cable, which connects to that trunk and gives the country a nationally controlled entry point into the global backbone.

This approach is cheaper and more realistic for a small island nation than building a full trans-Pacific route on its own. At the same time it is better than simply buying capacity from an external operator, because the country gains its own physical infrastructure and more control over critical connectivity. Submarine Networks calls this a "Sovereign Branch" model: the branch stays under RMI control, with NTA as owner and operator of IOKWE.

Historical context: before IOKWE there was HANTRU-1

Before IOKWE, RMI's main submarine backbone was HANTRU-1. It was completed and brought into service in 2010; the 2,917 km system connects Kwajalein with Guam and supports separate segments/branches for Majuro and Pohnpei. HANTRU-1 had 20 Gbps of installed capacity on two fiber pairs and an ultimate capacity of 160 Gbps, according to SubTel Forum's report on the system's completion.

Historically HANTRU-1 was a huge leap: before it, many island territories in the region depended mainly on satellite links, and submarine fiber gave a far more stable and faster international channel. But the problem is that for RMI it is still a bottleneck and a single point of dependency: at the time of publication the Marshall Islands had only one active international submarine cable, HANTRU-1, linking Majuro and Kwajalein with Guam.

Why IOKWE matters: not just speed, but resilience

The main value of IOKWE is redundancy, the duplication of international connectivity. The new cable is meant to become a second route so the country does not remain dependent on HANTRU-1 alone. For an island state this is not a "nice to have" but national-resilience infrastructure:

• if one cable is damaged, the country should not fully degrade to a satellite fallback;
• a backup route lowers the risk of prolonged outages for banks, government services, healthcare, education, and emergency communications;
• connecting to a large Google trunk potentially gives lower latency, higher capacity, and better routing quality toward global clouds and CDNs.

NTA directly ties the project to digital resilience, national development, telehealth, education, and digital entrepreneurship.

Funding and geopolitics

The project is backed by U.S. government funding and a feasibility study from the U.S. Trade and Development Agency (USTDA). In a broader context this is not only about telecommunications but about strategic infrastructure in the Pacific: Submarine Networks ties the Central Pacific Cable / Central Pacific Connect to the U.S. initiative to strengthen connectivity for Pacific island states amid competition for influence in the region.

DatacenterDynamics also reports that the U.S. government announced 132 million dollars of investment to connect the Marshall Islands and American Samoa to Pacific Connect. This makes IOKWE part of a much larger picture: the U.S., Google, and island states are building not just capacity but an alternative, politically more resilient digital architecture in the Pacific Islands.

What is known and what is not yet disclosed

Publicly known:

• IOKWE is a new submarine system for RMI, announced in March 2026;
• it will connect the Marshall Islands to Google Halaihai;
• the model is "trunk and island system"; RMI/NTA owns and operates the national branch;
• expected landings, per Submarine Networks and DatacenterDynamics, are Majuro and Ebeye;
• the project is meant to provide redundancy to HANTRU-1 and raise the country's resilience.

Not yet disclosed, or only partly disclosed: the exact length of IOKWE; the exact design capacity of the IOKWE branch system itself; the wet plant / cable ship / SLTE suppliers; a detailed route map; and the exact RFS / ready-for-service date.

Technically: what effect to expect

Seen through the eyes of network monitoring, IOKWE should change the RMI profile across several metrics at once:

• Path diversity. Today the dependency on HANTRU-1 means that the failure or degradation of one physical route can hit the whole country hard. IOKWE adds an alternative exit via Halaihai / Pacific Connect.
• Latency stability. Latency will not necessarily become dramatically lower for every direction, but it should become more stable thanks to Google's better backbone connectivity and the ability to route traffic through different Pacific Connect nodes.
• Capacity headroom. For a small island nation, even a share of a large Google trunk's capacity can mean a qualitatively different level of internet access, especially for cloud services, video, remote education, and telemedicine.
• Operational resilience. In reality what matters is not only fiber pairs and Tbps but having two independent operational chains: different cables, different landing arrangements, different repair scenarios, and different upstream routes. IOKWE closes exactly the "single cable country" pain.

Why this matters for GeoCables / monitoring weak points

IOKWE is a good example of a cable that matters not so much for its length as for how it changes the topology of risk. Before IOKWE, RMI is a classic single-international-subsea-cable dependency case: there is HANTRU-1, there is Guam as the key gateway, and any event on that route can have a national effect. After IOKWE the risk picture becomes different:

Before: RMI -> HANTRU-1 -> Guam -> Global Internet After: RMI -> HANTRU-1 -> Guam -> Global Internet RMI -> IOKWE -> Halaihai / Pacific Connect -> Guam / French Polynesia / Chile / broader Google backbone

For monitoring this means it is worth tracking not only cable status but also:

• changes in BGP paths out of RMI;
• the appearance of new upstream / peering via Google / Pacific Connect;
• latency Majuro / Ebeye to Guam, the US West Coast, Japan, Australia, and Chile;
• correlation between HANTRU-1 degradation and traffic shifting onto IOKWE;
• changes in packet loss / jitter during maintenance windows or storms;
• the appearance of new CDN / Google Global Cache / Cloud edge routes.

Short conclusion

IOKWE is the second submarine cable path for the Marshall Islands and their entry into Google's Pacific Connect architecture. It connects the country to Halaihai, reduces dependence on HANTRU-1, strengthens RMI's digital sovereignty, and turns the country from a "single-cable island" into a more resilient node of the central-Pacific network. The most interesting thing about IOKWE is not the absolute Tbps, but the topological meaning: a small national branch into a large trunk changes the entire risk map for a remote island nation.
