Below is a Central Command news release. The video above goes into much more detail and discusses some of the considerations that come into play when seizing a large container ship.
I was very impressed that the Destroyer was confident that they could target engine room from miles away. It was relatively short range, for a 5″/62, but having observed dozens of gun shoots, my observation was that even in a good exercise, only a minority of rounds were hits. This is a demonstrated capability to forcibly stop any vessel regardless of size, something cutters should be able to do.
Gee, maybe this is another reason larger cutters should have a 5″ gun.
U.S. Forces Disable Vessel Attempting to Enter Iranian Port, Violate Blockade
USCENTCOM
TAMPA, Fla. – 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.

One of the reports I saw on YouTube said that the USS Spruance fired non explosive rounds from her 5 inch gun into the engine room of a container ship. That’s pretty smart much less damage or loss of life.
As I recall modern Container Ships are also double hulled for structural support of the weight of whatever is stored inside their TEUs (Twenty-foot Equivalent Units) and FEU (Forty-foot Equivalent Units)! And unlike most other ships modern container ships and super tankers have only one massive low speed two-stroke crosshead diesel engine displacing over 2,300-tons, which probably means that a single 5”/62 gun isn’t likely to knock out by one shot…
On April 19, 2026, the USS Spruance (DDG-111), a US Navy Arleigh Burke-class guided-missile destroyer, fired several rounds from its 5-inch (127 mm) MK 45 gun into the engine room of the Iranian-flagged cargo vessel M/V Touska to disable its propulsion.
Key Details of the Operation:
The use of the 5-inch gun was described as a tactical decision to use a precise weapon for “disabling fire” while minimizing, or aiming to avoid, the excessive destruction that might result from using modern explosive ammunition, or large missiles.
