U.S. Navy Struggles Against Houthi Attacks in Yemen

September 15, 2024

Israeli Air Strikes and the Red Sea Crisis

In late July, Israeli airstrikes hit the Yemeni port city of Hodeidah. These attacks targeted transportation and energy infrastructure, marking Israel’s first military involvement in Yemen. The strikes followed a Houthi attack on Tel Aviv just a week earlier. These actions unfolded within the larger Red Sea crisis, a conflict that began in October 2023, disrupting international trade across the region.

Blockade of Bab al-Mandab Strait and Global Impact

The Houthis initiated a blockade of the Bab al-Mandab Strait as a response to the Gaza conflict. By January 2024, the blockade had severely reduced traffic in the Red Sea, a critical artery for global shipping. The blockade quickly caught the attention of Western powers. The United States launched Operation Prosperity Guardian, deploying a carrier strike group alongside 20 international allies to challenge Houthi control. Meanwhile, European nations launched Operation Aspides, focusing on escorting commercial vessels rather than direct combat with the Houthis.

Rising Costs and Tactical Challenges for the U.S. Navy

Despite the efforts of these operations, the Houthis remained a formidable opponent. Over 100 maritime incidents occurred in just six months, with a noticeable increase in attacks by June. The sinking of the MV Tutor, the second major vessel lost to Houthi forces, caused insurance premiums to spike. Although the U.S. Navy had the advantage in firepower, it struggled tactically. This naval conflict has become one of the most intense the U.S. has faced since World War II.

Operational costs are mounting. The price of Operation Prosperity Guardian is approaching $4 billion, and despite these expenditures, progress against the Houthis remains elusive. The high costs and limited success raise questions about the effectiveness of the U.S. military approach in this conflict.

Bab al-Mandab’s Strategic Importance and Economic Fallout

The Houthis’ attacks on shipping in the Red Sea have global implications. The Bab al-Mandab Strait is a strategic chokepoint for international trade. Any disruption in this region ripples through global supply chains, increasing costs and causing delays. The escalation of insurance premiums for ships traversing this region only adds to the economic strain. The Houthis have not only inflicted physical damage but also instilled fear among global shipping operators and insurers.

U.S. Navy’s Vulnerability to Asymmetric Warfare

The U.S. Navy is encountering a significant challenge in handling the Houthis’ unconventional tactics. In 2002, the Millennium Challenge war game demonstrated how the U.S. Navy could be overwhelmed by asymmetrical threats like those posed by Iran. In that exercise, Iranian forces relied on basic, dispersed methods to evade detection and cripple the U.S. fleet. The Houthis, although less equipped than Iran, are using a similar approach in the Red Sea, presenting a significant challenge for U.S. naval forces.

Global Geopolitical Constraints on U.S. Strategy

The U.S. Navy’s struggles are compounded by its global obligations. Tensions in the South China Sea have made it difficult to relocate forces to the Middle East, while other conflicts—such as those in Ukraine and South America—demand attention. The United States has had to make tough decisions, such as moving the USS Theodore Roosevelt from the South China Sea during a peak moment of tension between China and the Philippines. By doing so, Washington compromised its strategic position in the Pacific to address the Red Sea crisis.

The High Cost of Naval Warfare

Modern naval warfare is costly, and the current conflict in Yemen highlights this issue. U.S. warships, such as the Arleigh Burke-class destroyers, cost $2 billion to build and $7 million per month to operate. Repairs can easily run into the hundreds of millions, even for minor damage. For instance, the USS Cole bombing in 2000, a low-budget attack by Al-Qaeda, caused $240 million in damage with less than $1 million in explosives.

The economic mismatch extends to missile defense. The U.S. Navy is often forced to use multi-million-dollar missiles to destroy low-cost Houthi drones. This cost imbalance further strains the financial viability of ongoing naval operations.

European Naval Involvement and its Limitations

European involvement, led by Operation Aspides, has been hampered by various challenges. The European Union’s naval forces lack the number of ships needed to adequately defend against the Houthis. The absence of a unified command structure further weakens the effectiveness of these missions. Coordination between European and U.S. forces has been inconsistent, resulting in ineffective joint operations.

Diplomatic Limitations and Strategic Dilemmas

Diplomatic options are proving as difficult as military ones. The Yemeni government in Aden lacks widespread support, being viewed as corrupt and illegitimate. Strengthening this government has done little to shift the balance in the conflict. The broader international diplomatic landscape offers limited solutions. Washington would need to engage with powers like Russia and China, which complicates matters further due to the ongoing conflicts in Ukraine and Taiwan.

Resolving the Gaza conflict could weaken the Houthis’ justification for their actions in the Red Sea, but that approach carries political risks domestically for the U.S. government. Diplomatic and military options seem equally unappealing, leaving Washington with limited paths forward.

Washington’s Stalemate in the Red Sea Conflict

The conflict in Yemen, specifically the Red Sea crisis, has exposed a critical weakness in U.S. strategy. The United States has committed significant financial and military resources, yet it has made little progress against the Houthis. At the same time, global geopolitical constraints hinder its ability to fully address the conflict. As the U.S. Navy struggles with asymmetric warfare, the cost of maintaining operations in the Red Sea continues to rise. Washington finds itself trapped in a conflict where both military and diplomatic efforts have failed to deliver a resolution. The Houthis, meanwhile, continue to exploit the situation, strengthening their position as global trade and security remain at risk.
