U.S. Navy Deploys MH-60R Seahawk Helicopter From USS Truxtun Destroyer to Enforce Iran Blockade.

A U.S. Navy MH-60R Seahawk operating from the destroyer USS Truxtun is enforcing the American blockade of Iranian ports in the Arabian Sea, extending the ship’s surveillance and response reach far beyond the horizon as tensions with Tehran continue to escalate. Images released by United States Central Command on May 14, 2026, highlight how destroyer-based helicopters are being used to track, identify, warn, and if necessary, support interdiction operations against vessels attempting to challenge the blockade.

CENTCOM said U.S. forces have redirected 70 commercial ships and disabled four vessels since the operation began on April 13, demonstrating an increasingly aggressive maritime enforcement posture in one of the world’s most strategically critical waterways. The deployment also reflects the growing importance of shipborne rotary-wing assets in contested naval operations, especially after Iranian missiles, drones, and fast attack craft targeted USS Truxtun and other U.S. destroyers during a recent Strait of Hormuz transit.

The operational point is not that the MH-60R alone enforces a blockade. The helicopter gives a destroyer commander a lower-threshold instrument between radio warnings and the use of ship-launched missiles or naval gunfire. CENTCOM’s April 12 blockade notice stated that enforcement applied to vessels entering or leaving Iranian ports and coastal areas, while non-Iranian traffic through the Strait of Hormuz would not be impeded; that distinction requires identification, communication, and documented observation at close range. A destroyer can track traffic with radar, but the helicopter can move toward a contact, observe hull markings and deck activity, relay imagery, maintain standoff from the ship, and provide armed cover while bridge-to-bridge communications continue on Channel 16.

HSM-50 is a relatively new U.S. Navy expeditionary maritime strike squadron, established on October 1, 2021, at Naval Station Mayport, Florida, and formally commissioned on November 18, 2022. Its command history states that it operates six combat-ready MH-60R detachments for deployment aboard U.S. Navy cruisers, destroyers, and littoral combat ships. That matters for USS Truxtun because the detachment is organized for independent warship operations rather than carrier-only employment. In blockade enforcement, this structure allows a destroyer to conduct persistent maritime control without waiting for fixed-wing aircraft from a carrier air wing, although carrier aircraft remain important for range, mass, and larger ordnance.

The MH-60R is a three-crew, twin-engine helicopter built around the maritime strike and anti-submarine warfare mission. NAVAIR lists Sikorsky, a Lockheed Martin company, as the contractor, two GE T700-GE-401C or -401D engines as propulsion, an empty weight of 15,170 pounds, a maximum gross weight of 23,500 pounds, a length of 64 feet 10 inches, and a height of 17 feet. The U.S. Navy says the type reached initial operational capability in December 2005, entered deployment in 2006, and reached full operational capability in 2010. Its primary missions are anti-submarine warfare, surface warfare, electromagnetic warfare, command and control, and non-combat operations, with secondary roles including search and rescue, special warfare support, logistics, and intelligence, surveillance, and reconnaissance.

The helicopter’s most relevant capability in Hormuz is its sensor package. The AN/APS-153(V) maritime surveillance radar is integrated into the MH-60R mission system and includes identification friend-or-foe functions, automatic radar periscope detection and discrimination, and high-resolution imaging for littoral maritime awareness. The AN/AQS-22 airborne low-frequency sonar gives the MH-60R an undersea detection and classification role, even when the immediate mission is surface interdiction. In the Gulf of Oman and Strait of Hormuz approaches, where merchant traffic, patrol craft, drones, submarines, and potential mines can occupy the same battlespace, the sensor mix lets the aircraft contribute to both tactical enforcement and force protection.

The armament is structured for several levels of force. AGM-114 Hellfire missiles give the MH-60R a precision point-target weapon against small craft, bunkers, light vehicles, and fixed positions; the U.S. Navy describes the missile as a laser-guided, subsonic weapon weighing 98 to 107 pounds, using a solid-propellant rocket motor and shaped-charge, blast-fragmentation, or thermobaric warheads depending on variant. APKWS II gives a lighter option by converting a 2.75-inch Hydra rocket into a laser-guided munition; NAVAIR lists a 32.6-pound all-up round, 1,000 m/s maximum speed, Mk66 Mod 4 motor, and a 10-pound high-explosive warhead, with MH-60R integration completed in March 2014. The GAU-21 .50-caliber machine gun, used on MH-60R fleets, provides belt-fed fire out to roughly 2,000 meters, while the Mk 54 lightweight torpedo preserves the anti-submarine role with a 607-pound weapon and a 100-pound high-explosive warhead.

For blockade enforcement, the practical value of that weapons suite is discrimination. A Hellfire is not the default answer to a merchant vessel that fails to answer radio calls; it is a precision weapon for a defined military target or for a limited disabling shot if rules of engagement allow it. APKWS offers a smaller explosive effect against lightly built fast boats, exposed weapons, or specific machinery, but even that munition carries escalation and legal risk when used near commercial shipping. The crew-served gun is often more relevant for warning, suppression, and last-ditch defense, while the radar, electro-optical observation, and communications equipment do most of the work before any weapon is fired. This is why the helicopter fits the blockade mission: it supports compliance without forcing every encounter into a destroyer-scale engagement.

The strategic geography explains why this specific aircraft is useful around Hormuz. The U.S. Energy Information Administration assessed that oil flows through the Strait of Hormuz averaged 20 million barrels per day in 2024, about 20 percent of global petroleum liquids consumption, and that Hormuz carried more than one-quarter of global seaborne oil trade in 2024 and the first quarter of 2025. EIA also estimated that 84 percent of crude oil and condensate and 83 percent of liquefied natural gas moving through the strait in 2024 went to Asian markets, with China, India, Japan, and South Korea the main crude destinations. In that environment, U.S. naval presence is not only a bilateral signal to Iran; it is tied to the credibility of maritime movement for allied and partner economies.

The MH-60R is therefore a good fit for USS Truxtun’s mission, but not because it is a substitute for destroyers, maritime patrol aircraft, or carrier aviation. It fills the tactical space between wide-area naval control and face-to-face interdiction: close enough to inspect, armed enough to deter small craft, connected enough to feed the destroyer’s combat information center, and small enough to be launched repeatedly from a single warship. Its limitations are also clear. It has less endurance than fixed-wing aircraft, is exposed to weather and small-arms threats at low altitude, and depends on the ship for maintenance, fuel, and flight-deck availability. Still, for a blockade that must distinguish Iranian-port traffic from other commercial movement through a crowded energy chokepoint, the MH-60R provides the kind of measured, documented, and reversible presence that a destroyer alone cannot maintain at the same distance from the hull.
