Tensions between U.S. and Iranian naval forces in the Arabian Sea have intensified, culminating in a direct confrontation this week when an Iranian ship approached dangerously close to the USS Abraham Lincoln, one of the U.S. Navy’s premier aircraft carriers. American forces responded with gunfire and missile strikes, according to two U.S. officials who spoke to CBS News on condition of anonymity.
The incident unfolded earlier this week as the Iranian vessel closed in on the carrier. A U.S. Navy warship first attempted to engage the intruder using its 5-inch, 54-caliber Mark-45 deck gun—a fully automated cannon that has been a staple of American destroyers and cruisers since the 1970s. The gun, mounted on the forward deck, is valued for its reliability and versatility in surface and air defense roles. However, multiple rounds missed the target. It remains unclear whether the shots were intended as warnings or precision strikes, a detail with significant tactical and diplomatic implications.
When the cannon fire proved ineffective, a military helicopter was deployed, armed with AGM-114 Hellfire missiles. The helicopter successfully hit the Iranian vessel with two missiles. As of the latest reports, the condition of the ship and the fate of its crew are unknown, with no official details released on casualties or damage.
The USS Abraham Lincoln is operating in the Arabian Sea as the centerpiece of its carrier strike group, accompanied by destroyers including the USS Spruance and USS Michael Murphy. Additional guided-missile destroyers were also active in the area. The helicopter involved was likely either an MH-60R Seahawk, suited for anti-surface missions, or a Marine Corps AH-1Z Viper—though officials have not specified the exact type.
U.S. Central Command offered a terse response when contacted by CBS News: “We have nothing for you on this.” Such restraint is common in ongoing operations, where full details often emerge only after internal reviews.
This clash fits into a pattern of escalating maritime confrontations. In early February, U.S. forces downed an Iranian Shahed-139 drone that aggressively maneuvered toward the Abraham Lincoln. The carrier strike group had deployed to the region in late January, a move President Donald Trump publicly described as an “armada” to project strength amid rising tensions with Tehran.
Since the onset of broader U.S. military operations against Iran, American forces have reportedly damaged or destroyed more than 90 Iranian naval vessels, according to U.S. Central Command figures. These engagements highlight how naval skirmishes have become a routine element of the conflict.
The Mark-45 gun’s reported misses raise questions about factors such as range, sea state, or the Iranian vessel’s speed and maneuvers. Meanwhile, the Hellfire—a precision-guided missile originally designed for anti-armor roles but effective against surface targets—provided a lethal and accurate follow-up.
As details remain limited and neither side has issued a full public statement, the episode underscores the high stakes in the Arabian Sea. Commanders must balance rules of engagement with the risk of rapid escalation, while sailors in the region face constant hazards. The waterway has emerged as a critical theater where split-second decisions could influence the wider conflict.
