U.S. sailors aboard the USS George H.W. Bush watched Tuesday as the first Revolutionary Guard vessels appeared on the horizon of the Strait of Hormuz, beginning a daylong face-off that has become familiar to Iranian paramilitary and U.S. naval forces that pass through the narrow mouth of the Persian Gulf.
"What reason were they to be in an international corridor, other than to harass us?" Rear Adm. Kenneth Whitesell, commander of Carrier Strike Group 2, asked of the Iranian actions. "Was today the day they were going to come out and potentially deploy kinetic actions against us?"
President Donald Trump has warned that Iranian forces will be blown out of the water if they challenge U.S. naval vessels. U.S. commanders describe the Revolutionary Guard as increasingly behaving unprofessionally, with rocket launches and provocative actions.
Whitesell oversees the strike group that has the USS Bush at its heart. The Nimitz-class, nuclear-powered carrier left its home port of Norfolk, Va., on Jan. 21 -- Trump's first full day in office. Its passage through the strait closes a roughly three-month gap in which America had no aircraft carrier in the Persian Gulf. A similar gap happened in the fall of 2015 -- the first for the U.S. since 2007.
Its overall mission is providing a base for airstrikes against the Islamic State extremist group. The ship's contingent of F-18 fighter jets began bombing the extremists in February as the vessel transited through the Mediterranean Sea.
But serving as a counterbalance to Iran and assuring America's Gulf Arab allies in the region also remains vital, Whitesell said. While acknowledging that Trump and Defense Secretary James Mattis have strong suspicions about Iran, he said there hadn't been any change in his orders in how to deal with the Islamic Republic.
"The political aspect of the United States has kind of been in our wake," the rear admiral said.
Threats, however, remain. After a Saudi naval vessel came under attack from a purported "drone" boat off the coast of war-torn Yemen, in the Bab al-Mandeb Strait in the Red Sea, U.S. vessels in the strike group changed their routine to protect themselves while passing, said Capt. Will Pennington, the commanding officer of the USS Bush.
"Some of our escort ships arrived in advance of us and provided security in that Bab al-Mandeb, and a few lagged a few days behind, so our coverage of that area was extended," Pennington said. "That same threat could exist here in the Strait of Hormuz or any other strait."
Small vessel attacks also include the October 2000 boat-borne bombing by al-Qaida on the USS Cole, which killed 17 U.S. sailors while the ship was refueling in Yemen's Aden harbor.
The worry grows for U.S. officials as the Navy recorded 35 instances of what it describes as "unsafe and/or unprofessional" interactions with Iranian forces in 2016, compared with 23 in 2015. Before this week, there had been six, said Lt. Ian McConnaughey, a spokesman for the U.S. 5th Fleet, based on the nearby island of Bahrain.
Of the incidents last year, the worst involved Iranian forces capturing 10 U.S. sailors and holding them overnight. It became a propaganda coup for Iran's hard-liners, as Iranian state television repeatedly aired footage of the Americans on their knees, their hands on their heads.
Iranian forces view the American presence in the Persian Gulf and especially the Strait of Hormuz as a provocation by itself. They in turn have accused the U.S. Navy of unprofessional behavior.
At dawn Tuesday, the USS Bush and its strike force entered the strait, which at its narrowest point is 21 miles wide, in the waters between Iran and Oman.
Iranian authorities demanded that the Americans leave the area, though both the U.S. Navy and a nearby Omani warship said the strike group was in Omani waters.
The Iranians had speedboats and other craft, several displaying the Kalashnikov-rifle emblem of the Revolutionary Guard. U.S. helicopters circled overhead as some of the Iranians used telephoto lens and video cameras to film the carrier -- while international journalists invited onboard the USS Bush filmed them.
On the bridge, a sailor called out: "There's nine. Reports of weapons being loaded."
But the Iranians merely stood alongside their machine guns, moving at their closest some 940 yards from the carrier as armed American sailors kept watch.
Hours later, the carrier exited the strait and entered the waters of the Persian Gulf, leaving the Iranians behind.
Still, Whitesell rated the day's danger as a 7.5 out of 10, because of fog and other issues compounding the possible threat the Iranian vessels posed.
"They had every one of those weapons manned, and we also have video data that they were arming every one of those weapons," he told journalists.
