Iranian IRGC vessels conduct 'harassing' approaches of US navy ships
The IRGCN vessels repeatedly crossed the bows and sterns of the U.S. vessels at extremely close range and high speeds, including multiple crossings of the Puller with a 50 yard closest point of approach (CPA) and within 10 yards of Maui's bow.
The U.S. crews issued multiple warnings via bridge-to-bridge radio, five
short blasts from the ships' horns and long range acoustic noise maker
devices, but received no response from the IRGCN.
After approximately one hour, the IRGCN vessels responded to the
bridge-to-bridge radio queries, then maneuvered away from the U.S. ships and opened distance between them.
The IRGCN's dangerous and provocative actions increased the risk of
miscalculation and collision, were not in accordance with the
internationally recognized Convention on the International Regulations for
Preventing Collisions at Sea (COLREGS) "rules of the road" or
internationally recognized maritime customs, and were not in accordance with the obligation under international law to act with due regard for the safety of other vessels in the area.
