Extensive damage from Iranian missile and drone attacks on Naval Support Activity (NSA) Bahrain, a critical US military installation, has finally come into clearer focus, compelling the Pentagon to undertake a sweeping strategic reassessment of its entire footprint in the Gulf. An investigation by The Wall Street Journal revealed that between late February and June, repeated strikes penetrated US air defenses, causing destruction far greater than what American defense officials had publicly acknowledged.

The investigation, which drew on satellite imagery, social media footage, and interviews with current and former US servicemembers, highlighted significant hits to key facilities. Among the structures damaged were the command headquarters, at least a dozen other buildings, and two vital satellite communications terminals essential for military operations. While the Pentagon maintained that no personnel were killed and operations continued, most US military staff had been evacuated from the base before the heaviest barrages, leaving only a limited number of personnel on site.

Captain Tim Hawkins, a spokesperson for US Central Command, defended the military’s approach, stating, "Centcom rightfully prioritised the protection of people over buildings, and our strategy of protecting people worked." He noted that out of more than 8,000 Iranian missiles and drones launched, only two resulted in US fatalities. Hawkins also emphasized the scale of the American response, asserting that US forces struck over 13,500 targets in return.

Beyond the physical destruction, these attacks have forced senior US defense officials to confront a fundamental question: whether long-established American bases in the Gulf remain viable against the backdrop of Iran’s advanced arsenal of precision-guided missiles and armed drones. This strategic dilemma has spurred the Pentagon to explore various options for adapting its regional presence. These considerations include redesigning the Bahrain base itself, potentially reducing the US military presence in countries like Kuwait and Saudi Arabia, relocating some command functions further west, and even placing more facilities underground for enhanced protection. Military planners are also weighing the benefits of distributing capabilities across multiple smaller locations rather than concentrating them at a few large, vulnerable bases.

No final decisions have been made regarding these proposed changes. However, Israel has emerged as a potential candidate for hosting additional US military assets, particularly after accommodating dozens of American aircraft during the recent conflict, according to officials cited in the report. This shift underscores a broader re-evaluation of alliances and strategic positioning in the Middle East.

The financial repercussions of these attacks are substantial, though a complete estimate remains elusive. The Pentagon has declined to provide Congress with a full accounting of the damage suffered by US bases. When pressed by lawmakers in May, US Defence Secretary Pete Hegseth deflected, asking, "What is the cost of Iran obtaining a nuclear weapon?" The Pentagon later confirmed that its $29 billion estimate for the conflict’s overall cost did not encompass damage to military installations.

Independent analysis from the Center for Strategic and International Studies (CSIS) estimates the total conflict cost at roughly $40 billion, with damage to US bases ranging between $2.2 billion and $5.1 billion. The Wall Street Journal, using publicly available Defense Department construction models, estimated that rebuilding just the damaged structures at NSA Bahrain would cost approximately $400 million. This figure excludes specialized military equipment, communications systems, or necessary security upgrades. For instance, two destroyed AN/GSC-52B satellite communications terminals alone were valued at about $20 million each by CSIS.

Military experts suggest the conflict exposed critical weaknesses in infrastructure built decades ago, long before Iran developed its current capabilities in precision missiles and drones. NSA Bahrain, unlike many overseas military installations, also served as a residential community, housing families and offering amenities like restaurants, schools, and recreational facilities. This dual function complicated defensive strategies and highlighted the vulnerability of such integrated bases.

The renewed urgency around these strategic discussions comes after previous proposals to move some US military assets farther from Iran during President Donald Trump’s first term were never implemented. Now, following months of sustained missile strikes reaching America’s most significant naval base in the region, the conversation about adapting to modern threats has returned with undeniable force. US Secretary of State Marco Rubio recently met with Bahrain’s King Hamad bin Isa Al Khalifa and other Gulf leaders, aiming to reassure allies of Washington’s enduring commitment to regional security amidst these evolving challenges.
