Operation Prosperity Guardian. It is a multinational United States Navy-led security initiative established in December 2023 in response to attacks on international shipping by the Houthi movement from Yemen. The operation aims to ensure freedom of navigation and protect commercial vessels in key maritime regions including the Red Sea, the Gulf of Aden, and the Bab el-Mandeb strait. Formed under the umbrella of the existing Combined Maritime Forces and its Combined Task Force 153, the coalition represents a significant international effort to counter threats to global trade routes.

Background and context

The operation was launched following a significant escalation in attacks by the Houthi movement on commercial shipping transiting the Red Sea in the wake of the Israel–Hamas war. The Houthis, who control much of western Yemen, declared they would target vessels linked to Israel or its allies in solidarity with Hamas. These attacks, employing anti-ship ballistic missiles, unmanned aerial vehicles, and small boats, threatened one of the world's most critical maritime chokepoints. The Bab el-Mandeb strait is a vital artery for global commerce, with nearly 15% of seaborne trade passing through it, including significant volumes of oil from the Persian Gulf and trade between Asia and Europe. The deteriorating security situation prompted major shipping firms like Maersk and Hapag-Lloyd to reroute vessels around the Cape of Good Hope, causing substantial delays and increased costs.

Objectives and mission

The primary objective is to ensure the safe passage of merchant vessels through the Red Sea and adjacent waterways by deterring and responding to Houthi attacks. The mission focuses on providing a coordinated naval presence to conduct maritime security operations, including surveillance, escort duties for vulnerable ships, and direct defense against airborne and seaborne threats. A key aim is to uphold the principle of freedom of navigation as codified under the United Nations Convention on the Law of the Sea, thereby stabilizing a crucial corridor for the global economy. The operation seeks to de-escalate regional tensions and prevent a broader conflict while protecting seafarers from over 50 nations who transit the area.

Participating forces

The coalition is led by the United States Navy's Fifth Fleet, headquartered in Bahrain. Initial participants included the United Kingdom, which deployed the HMS Diamond, and other nations such as Canada, France, Italy, Netherlands, Norway, Seychelles, and Spain. Several allied nations, including Australia, Denmark, Germany, New Zealand, and South Korea, have contributed personnel or support without deploying warships. Notably, some regional powers and major naval forces have opted not to join the publicly named coalition, choosing instead to conduct independent patrols, as seen with China and India. The force operates in coordination with the existing Combined Maritime Forces structure.

Operational history

The operation was formally announced on 18 December 2023 by United States Secretary of Defense Lloyd Austin. Initial actions involved the USS *Carney*, USS *Mason*, and other coalition warships successfully intercepting multiple anti-ship ballistic missiles and unmanned aerial vehicles launched by the Houthi movement. In January 2024, following continued attacks, the coalition shifted from a purely defensive posture. The United States and the United Kingdom, with support from allies, executed major strikes on Houthi targets in Yemen with Tomahawk missiles and combat aircraft from the USS *Dwight D. Eisenhower* carrier strike group and RAF Akrotiri. These strikes targeted radar sites, command and control nodes, and weapons storage facilities.

Impact and consequences

The operation has had a direct but complex impact on the security situation. While it has successfully defended numerous merchant ships and degraded some Houthi capabilities, attacks have persisted, demonstrating the difficulty of completely neutralizing the threat. Commercially, insurance premiums for vessels transiting the Red Sea have soared, and many shipping companies continue to avoid the route, leading to extended transit times, increased fuel costs, and disruptions to global supply chains. The military escalation has raised concerns about a wider regional conflict, potentially drawing in other actors in the already volatile Middle East. The situation has also highlighted the vulnerabilities of critical maritime infrastructure to asymmetric warfare.

International reactions

International response has been mixed. The operation has received public support from key allies like the United Kingdom, the European Union, which launched its own naval mission EUNAVFOR Aspides, and major trading nations concerned with economic stability. However, it has faced criticism from Russia and China, who have questioned its legal basis and accused it of exacerbating regional tensions. Within the United Nations Security Council, discussions have been divisive. The Houthi movement has vowed to continue its attacks, framing them as a legitimate response to the Gaza conflict. Regional powers like Saudi Arabia and Oman, engaged in delicate peace talks with the Houthis, have expressed concern over the potential for further escalation.
