Port Sudan

Overview

Port Sudan is a city on the Red Sea coast and Sudan’s principal seaport. It serves as the country’s maritime gateway for trade and has also been an outlet for oil transported from inland production areas. Its strategic value extends beyond Sudan: ships using the Red Sea travel between the Suez Canal and the Indian Ocean, a route carrying approximately 12 percent of global maritime trade. Control of the port therefore affects Sudan’s access to overseas markets and the security interests of states active along the waterway.

Geography

Port Sudan’s coastal position connects inland Sudan to Red Sea shipping lanes. Vessels traveling north can reach the Suez Canal and Mediterranean Sea; those traveling south can reach the Indian Ocean through the southern Red Sea. This location has drawn interest from governments seeking naval logistics facilities, access to regional trade routes, or influence over maritime traffic. For Sudan, the port’s value also depends on its links to inland transport infrastructure, which allow goods and oil to move between the coast and the country’s interior.

Modern history

Oil gave Port Sudan particular economic importance before southern Sudan’s independence in 2011. Most of Sudan’s main oil reserves lay in the south, while refining and transport infrastructure lay in the north, including Khartoum and Port Sudan. Before the independence referendum, oil accounted for about 95 percent of Sudan’s export revenue. Southern production supplied approximately 65 percent of the Khartoum government’s income and 98 percent of the southern government’s income. The south had no foreseeable alternative export route to the Red Sea except through northern infrastructure. Port Sudan was consequently part of an export system on which both governments depended, even as they disagreed over oil revenues and the approaching division of the country.

Port Sudan later became a focus of Russian plans for a naval facility. During a 2017 visit to Sochi, Sudanese ruler Omar al-Bashir proposed hosting a Russian naval base. In November 2020, Vladimir Putin approved a 25-year agreement for a logistics facility near Port Sudan. Its terms permitted up to 300 military and civilian personnel and four naval vessels, including nuclear-powered vessels, as well as air-defense and electronic-warfare assets. The agreement included an option for an automatic 10-year extension. Russia sought a logistics hub from which to extend its presence along the Red Sea route between the Suez Canal and Indian Ocean.

Sudan suspended the Russian agreement in spring 2021 and sought removal of equipment already installed for the project. In June, Sudan’s military announced that it was renegotiating the terms. After his October 25, 2021 military coup, Abdel Fattah al-Burhan gave qualified support to reviving the arrangement, while Sudanese military leaders continued to review it. The sequence left the proposed facility subject to negotiations rather than operating as an established Russian base.

Security

Port Sudan was the planned unloading point for an Iranian-regime arms shipment intercepted by Israel in March 2014. The Panama-flagged Klos-C carried weapons concealed beneath sacks of cement. Its planned route ran through Port Sudan and then overland across the Sinai Peninsula into Gaza. Israeli naval commandos stopped the vessel on March 5 near the Eritrea–Sudan maritime border, about 1,500 kilometers from Israel’s coast. The ship reached Eilat on March 8 for unloading and examination. Its cargo included 40 Syrian-made M-302 rockets, 181 Iranian-made 122 mm mortar shells, and about 400,000 rounds of 7.62 mm ammunition. The interception prevented that shipment from reaching Port Sudan and continuing toward Gaza.

The Sudanese civil war began in April 2023 when fighting erupted between al-Burhan’s army and Hemedti’s Rapid Support Forces. The rivals had disagreed over Sudan’s transition to civilian government and the integration of the Rapid Support Forces into the army. Fighting for Khartoum drove al-Burhan to establish his headquarters in Port Sudan, making the Red Sea city his wartime capital and a center for military command and logistics. Sudan’s armed forces remained based there in 2026 while the war continued. Defections from the Rapid Support Forces also prompted concern that former commanders might infiltrate army positions in Port Sudan and Khartoum.

Present day

Foreign interest in Port Sudan has continued during the war. After Sudan and Iran restored diplomatic ties in December 2023, the Iranian regime supplied Sudan’s army with weapons, including drones and munitions, while pursuing naval access to Port Sudan. It reopened its embassy in the city as relations resumed under al-Burhan. A naval foothold on Sudan’s coast would extend Iranian reach along a commercial corridor near Israel and other Red Sea states. Iran’s pursuit of access remains distinct from the Russian agreement; neither establishes an operating Iranian base at Port Sudan.

Russian and Sudanese foreign ministers announced in February 2025 that they had reached a deal for a Russian naval base at Port Sudan. A later Sudanese government confirmation described the long-running agreement as still being finalized. Those announcements followed years of proposals, suspension, and renegotiation; they did not establish that the planned facility had begun operating. Port Sudan’s wartime role, commercial function, and place on the Suez Canal–Indian Ocean route continue to make decisions about foreign naval access consequential for Sudan and for regional maritime security.
