The Sultanate of Oman occupies a highly sensitive geopolitical position in the Middle East. Situated on the southeastern corner of the Arabian Peninsula, its coastline stretches along the Arabian Sea, the Gulf of Oman, and the Persian Gulf, placing it adjacent to some of the world's most critical maritime trade routes. Most notably, Oman controls the southern waters of the Strait of Hormuz—the vital maritime corridor through which approximately one-fifth of the world’s petroleum consumption passes daily.
To defend its sovereignty, protect critical maritime lanes, and maintain regional stability, Oman has built a professional and well-equipped military, known as the Sultan's Armed Forces (SAF). At the same time, Oman has pursued a highly distinctive foreign policy characterized by strict neutrality, regional mediation, and balanced diplomatic relations, particularly between its fellow Gulf Cooperation Council (GCC) members and the Islamic Republic of Iran. To understand how this strategic defense posture is funded by Oman's historical economic developments, see historical trade networks. To see how these defense expenditures are integrated into modern logistics and infrastructure, refer to industrial and logistics hubs.
The Sultan’s Armed Forces (SAF) are highly professionalized and rank among the most effective military forces in the Arab world. The SAF’s primary doctrine is defensive, focusing on protecting national territory, securing maritime borders, and maintaining internal security. The military is structured into four main branches, all under the command of the Sultan:
In addition to these branches, Oman operates several paramilitary forces, including the Royal Oman Police (ROP), which manages internal security, border control, and coast guard duties. To understand the political and administrative governance of these forces, see how they fit within the absolute monarchy and formal governance.
Maintaining a professional military in a volatile region requires substantial financial resources. Oman has historically allocated a significant portion of its national budget to defense and national security.
Throughout the 2010s, Oman's defense spending as a percentage of GDP was among the highest in the world, frequently exceeding 10% of GDP. In terms of total government expenditure, defense and security regularly absorbed over 30% of the state budget. While this high spending ensured national security, it also represented a severe fiscal burden, diverting capital away from non-oil economic development and social infrastructure. This high level of spending is a crucial variable in analyzing military expenditure as a percentage of GDP).
Under Sultan Haitham’s fiscal consolidation program, the government has sought to rationalize defense spending. While maintaining military readiness remains a top priority, the government has implemented cost-saving measures, including delaying non-essential procurement, streamlining administrative costs, and encouraging local defense production. The goal is to reduce defense spending toward a more sustainable level of 5% to 6% of GDP, freeing up fiscal space for sovereign stability and fiscal policy) and national security financing initiatives.
Oman's military responsibilities extend far beyond its borders due to its stewardship of the Strait of Hormuz. The Musandam Peninsula, an Omani exclave separated from the rest of the country by the United Arab Emirates, juts into the strait, giving Oman administrative control over the inbound and outbound shipping lanes.
The Strait of Hormuz is physically narrow, with its narrowest point measuring approximately 39 kilometers. Due to shallow water and navigation hazards, ships must follow a Traffic Separation Scheme (TSS) consisting of two-mile-wide inbound and outbound lanes, separated by a two-mile-wide buffer zone. The deepwater channel used for these lanes lies entirely within Oman's territorial waters in the Musandam Governorate.
The Royal Navy of Oman, in coordination with the Royal Air Force, maintains a constant patrol presence in the Musandam region. Their primary mission is to ensure the safe passage of commercial shipping, monitor maritime traffic, and prevent illegal activities, such as smuggling and piracy.
To manage this strategic responsibility, Oman has adopted a cooperative approach. It co-manages the shipping lanes with Iran, which controls the northern half of the strait. Despite intense regional tensions and occasional maritime incidents involving Western tankers and Iranian forces, Oman has successfully maintained its role as a neutral, stabilizing force in the strait, ensuring that commercial shipping continues to flow without major disruptions.
Oman’s defense doctrine is inseparable from its foreign policy of neutrality and quiet diplomacy. While Oman is a member of the Gulf Cooperation Council (GCC) and maintains close security relations with its Arab neighbors, it has consistently refused to join regional military alliances or participate in regional conflicts, such as the Saudi-led military intervention in Yemen.
Oman's relationship with Iran is particularly unique. This relationship is built on historical gratitude; in the 1970s, Iran’s Shah sent military forces to assist Sultan Qaboos in defeating the Dhofar Rebellion. Since then, Muscat and Tehran have maintained stable, cordial relations.
This unique positioning has allowed Oman to serve as a vital diplomatic bridge. Muscat has repeatedly mediated regional and international crises, including facilitating back-channel talks between the United States and Iran that led to the 2015 Joint Comprehensive Plan of Action (JCPOA) nuclear deal, negotiating the release of Western hostages held in Iran, and hosting peace talks between Yemeni factions. This neutral stance is a calculated defense strategy: by maintaining open communication channels with all regional actors, Oman reduces the likelihood of being drawn into a devastating conflict.
While Oman maintains cordial relations with Iran, its primary security and defense alliances are with Western powers, most notably the United Kingdom and the United States.
Oman's security relationship with the United Kingdom is historically deep, dating back to eighteenth-century treaties of friendship. British officers played a critical role in organizing and training the Sultan's Armed Forces during the mid-twentieth century. Today, the UK and Oman maintain a Joint Defense Agreement, and British forces regularly train in Oman's vast desert training grounds. A cornerstone of this training is the Ras Al Madrakah Joint Training Area in Al Wusta.
Oman also maintains a strong strategic partnership with the United States. In 1980, Oman became the first Gulf state to sign a formal military access agreement with the US, granting American forces access to Omani airfields and ports. This agreement has been renewed and expanded over the decades. Today, the US military utilizes Omani facilities, such as the Port of Duqm and Salalah, for logistical support and maritime patrols, enhancing Oman's deterrence capabilities without requiring a permanent foreign military base on Omani soil.
Oman is a founding member of the Gulf Cooperation Council (GCC), established in 1981 alongside Saudi Arabia, Kuwait, Bahrain, Qatar, and the United Arab Emirates. While Oman participates in GCC economic integration initiatives and regional security discussions, it has consistently maintained its diplomatic and military independence.
Oman has historically resisted efforts to transform the GCC into a tighter political or military union, fearing that such integration would compromise its sovereignty and its neutral foreign policy. For instance, Oman declined to participate in the Peninsula Shield Force's deployment to Bahrain in 2011 and remained strictly neutral during the 2017-2021 Qatar diplomatic crisis. This independent stance has occasionally caused friction with its larger GCC neighbors, but it has ultimately preserved Oman's status as the region's trusted mediator, ensuring its long-term security in a fractured geopolitical landscape.
Oman's military and paramilitary forces represent a significant financial investment, reflecting the high cost of maintaining security and neutrality in one of the world's most volatile regions. The Sultan's Armed Forces have proven highly effective at defending the nation's borders, securing the vital Strait of Hormuz, and maintaining internal stability.
As Oman pursues its ambitious Vision 2040 economic transition, the challenge will be to balance the high fiscal demands of national defense with the urgent need for domestic economic development. By rationalizing defense spending, pursuing local defense industrialization, and continuing its wise foreign policy of neutrality and mediation, Oman can ensure that its armed forces remain a guarantor of national sovereignty and economic prosperity for decades to come.
