More than 300 American service members have been injured during the conflict with Iran, with one of the sharpest jolts coming from a strike on Prince Sultan Air Base in Saudi Arabia that has underscored the growing vulnerability of US forces across the Gulf. The latest attack, carried out on Friday, involved six ballistic missiles and 29 drones, and by Saturday the number of wounded had risen to at least 15, according to updated reporting, after an earlier US official account put the figure at 12. The assault marked the third strike on Prince Sultan within a week and left several troops seriously hurt, while also damaging American aircraft on the ground. Earlier reporting said two personnel had sustained serious injuries; later accounts said five were in serious condition as officials continued to assess the aftermath. The discrepancies reflected the fog that has surrounded battlefield reporting throughout the war, but the broader picture has remained consistent: the Saudi base has become an increasingly exposed node in a conflict that Washington had once suggested was degrading Iran’s military capabilities.
Prince Sultan Air Base, south-east of Riyadh, has long served as a critical site for American air operations, surveillance and logistics in the region. Damage reported after the attack included refuelling aircraft, and one account said a US E-3 Sentry airborne warning and control aircraft was also hit, a potentially significant setback because such aircraft are central to monitoring missiles, drones and hostile aircraft across a wide theatre. If confirmed in full, that would deepen concern about how effectively American assets are being shielded even at heavily defended facilities.
The strike also sharpened questions about the wider course of the war, which Reuters said began on February 28 and has already left 13 American troops dead and more than 300 wounded. Most of those injured have returned to duty, but the scale of the casualty count has become harder for Washington to downplay as attacks have spread beyond direct US-Iran exchanges to a broader regional contest involving Gulf infrastructure, commercial shipping lanes and partner states. The cumulative toll has become politically sensitive because it clashes with earlier claims from senior US officials that Iran’s ability to retaliate had been sharply curtailed.
Washington’s answer has been to pour more military power into the region. Associated Press reported that additional Marines, warships and carrier strike groups have been sent towards the Middle East, including the USS Tripoli with about 2,500 Marines aboard, while further reinforcements from the United States are on the way. At the same time, the administration has continued to signal that it does not want a large-scale ground war, even as internal planning has reportedly begun for more aggressive contingencies. That tension between military build-up and political caution has become one of the defining features of the campaign.
Officials have tried to frame the mobilisation as leverage rather than a prelude to invasion. Secretary of State Marco Rubio has said Washington believes it can meet its aims without deploying ground combat forces on a major scale, yet reports of Pentagon planning for limited raids or other ground operations have kept speculation alive. The message reaching allies and markets is mixed: the United States is reinforcing heavily, but it is still trying to avoid saying how far it is prepared to go.
For Saudi Arabia and other Gulf states, the attack has been another reminder that geography is narrowing the margin for staying insulated. Iran’s retaliatory strategy has increasingly focused on economic disruption and pressure on US regional basing, while the conflict has begun to widen through other actors. The Houthis’ entry into the war has added another layer of instability, with missile launches towards Israel and fresh concern over shipping routes already strained by turmoil around the Strait of Hormuz and the Red Sea approaches. That has turned the military contest into an economic one as well, affecting energy markets, aviation and insurance costs far beyond the battlefield.
