The Iranian vessel approached within 150 yards of the coastal patrol ship USS Thunderbolt and did not respond to attempts to establish communications, officials said.

The Thunderbolt crew then fired warning flares and sounded the internationally recognised danger signal of five short blasts on the ship’s whistle, but the Iranian vessel continued inbound, officials said.

According to a statement released by the US Navy:

“As the Iranian vessel proceeded toward the U.S. ship, the crew again sounded five short blasts before firing warning shots in front of the Iranian vessel.”

The Iranian vessel halted its approach after the warning shots were fired, officials said, noting that the Iranian vessel’s actions were not in accordance with internationally recognised “rules of the road,” nor with internationally recognised maritime customs, thus creating a risk for collision.

The USS Thunderbolt is a Cyclone class patrol ship. The primary mission of these ships is coastal patrol and interdiction surveillance, which according to the US Navy is an important aspect of littoral operations outlined in the Navy’s strategy, “Forward…From the Sea.”

These ships also provide full mission support for U.S. Navy SEALs and other special operations forces.

I don’t get it are the Iranian actions against international law ? If yes no warning shots should be fired just blow them to kingdom come. Iran has almost certainly killed hundreds of UK and thousands of US troops in Iraq and Afghanistan. I think warning shots are not an acceptable response.

Yes, but wars aren’t particularly helpful are they?


Like with almost everything “international law” is either non existent or very vague.

Certainly it is behaviour contrary to professional and military norms.

If the IRGC jihadists want to meet their 72 virgins, the USN should oblige.

Good on the usn for what they done in a mature and responsible way .the Iranian captain knew after the flare and hooter blasts it was a nice salvo of shells coming his way and a nice swim to hell,all done in legitimate military protocol .well done boys
