Projectile event in Iran, Islamic Republic of on Sun 19th April 2026

U.S. forces operating in the Arabian Sea enforced naval blockade measures against an Iranian-flagged cargo vessel attempting to sail toward an Iranian port, April 19. Guided-missile destroyer USS Spruance (DDG 111) intercepted M/V Touska as it transited the north Arabian Sea at 17 knots enroute to Bandar Abbas, Iran.

American forces issued multiple warnings and informed the Iranian-flagged vessel it was in violation of the U.S. blockade. After Touska’s crew failed to comply with repeated warnings over a six-hour period, Spruance directed the vessel to evacuate its engine room. Spruance disabled Touska’s propulsion by firing several rounds from the destroyer’s 5-inch MK 45 Gun into Touska’s engine room. U.S. Marines from the 31st Marine Expeditionary Unit later boarded the non-compliant vessel, which remains in U.S. custody.

American forces acted in a deliberate, professional, and proportional manner to ensure compliance. Since the blockade’s commencement, U.S. forces have directed 25 commercial vessels to turn around or return to an Iranian port.
