Background

USS Frank E. Petersen Jr. (DDG-121) transited the Strait of Hormuz on 11 April 2026 alongside USS Michael Murphy as part of a declared US Navy mine clearance mission. CENTCOM stated both destroyers conducted the transit without incident. The IRGC denied the ships entered the strait at all and warned any military vessel attempting transit 'will be dealt with severely.'

DDG-121 is an Arleigh Burke-class Flight IIA destroyer commissioned in 2018. The ship is named after General Frank E. Petersen Jr., the first African American officer to fly for the US Marine Corps and the first Black general in the corps. Arleigh Burke destroyers carry the Aegis combat system, Tomahawk Cruise Missiles, and Standard Missiles, giving them a multi-domain strike and air-defence capability.

The Hormuz transit marked one of the first declared US Navy mine-clearing operations in the strait since Iran seeded it with mines following the outbreak of war in late February 2026. The conflicting CENTCOM and IRGC accounts reflect a broader information battle over freedom-of-navigation in one of the world's most strategically important chokepoints.
