Saudi Arabia's Defense Challenges Amid Houthi Missile and Drone Attacks

Recent Houthi attacks have struck Saudi energy facilities and civilian airports, killing at least 20 people, including a strike on Riyadh's King Khalid Airport that killed 13 victims. The Iranian-backed group has also targeted Saudi Aramco headquarters and contested control of Yemen's Red Sea coastline, a key route for global energy supplies.

Analysts note that Saudi Arabia’s vast territory makes comprehensive air defense difficult. "Over the last eight months, they have been facing threats from every direction," said Elizabeth Dent, senior fellow at the Washington Institute for Near East Policy. Thomas Juneau of Chatham House added that protecting numerous critical sites across such a large area is "extremely difficult."

A global shortage of interceptor missiles, exacerbated by the wars in Ukraine and the Middle East, has limited Saudi access to U.S.-made Patriot systems. U.S. Secretary of State Marco Rubio said the demand for Patriot interceptors is "probably the most in-demand product right now in the defense field." Lockheed Martin’s Tim Cahill confirmed that international demand for the interceptors remains strong.

The Houthi force employs swarms of inexpensive drones alongside ballistic missiles, complicating Saudi defenses. Allison Minor of the Center for Strategic and International Studies explained that the rebels use large numbers of cheap drones to distract and exhaust defenses before launching more destructive missile attacks.

Saudi Arabia has purchased 730 Patriot interceptors from the United States since 2020, but the high cost—up to $4 million per unit—and the system’s design for ballistic missiles limit its effectiveness against drone swarms. Analysts suggest cheaper, Ukrainian-developed drone interceptors as a possible supplement, though they require trained operators and extensive training.

Critics also point to limitations in Saudi military readiness. Aaron MacLean, a national security analyst, said the armed forces are structured around regime security rather than operational excellence, noting that "you can spend all the money you want on your military and your missile defenses, but you also have to have a culture of readiness and excellence among the troops responsible."

In response to the threat, Saudi Arabia has sought air-defense support from multiple partners, invoking a mutual defense pact with Pakistan and Turkey, and receiving assistance from France, the United Kingdom, Egypt, Greece, and Italy. Minor warned that such a patchwork of systems could become difficult to manage, raising questions about interoperability.

The sustainability of the Houthi campaign remains uncertain, with analysts unsure whether the group can maintain its current pace of attacks over the long term.
