[Ed. – The Iranian Revolutionary Guard units conducted surveillance of the John C Stennis formation in the Strait of Hormuz, and reportedly performed some rocket launches. However, the U.S. Navy’s statement on the rocket launches is that they weren’t directed at the Stennis group. There’s no reporting I can find on the distance from the Stennis at the time of the rocket launch(es), but the bottom line is that the Navy didn’t consider it bad seamanship, provocative, or threatening. That tells me it wasn’t. This is in contrast to the Navy’s clear statement in January 2016 that rocket launches conducted by Iran in the Strait of Hormuz, near the USS Harry S Truman, were highly provocative and unsafe.]
