To monitor the situation, the US Navy was patrolling the Persian Gulf. Its main task was to protect oil routes from attacks. The Navy's rules of engagement weren't public, but, according to The New York Times, ships were told to be cautious to avoid the US entering the war or causing an "international incident."

The commanding officer was Capt. Will C. Rogers III. According to a Middle East correspondent from the time, he had been acting recklessly aggressive in the month before the incident. Yet he was later awarded the Legion of Merit, for his service as commander between 1987 and 1989.

On July 3, 1988, the USS Vincennes and another US vessel were caught in a skirmish with Iranian gun boats. The skirmish began just after 10 a.m. Forty minutes later, the US Navy fired at the gun boats, and sunk two of them. In initial reports, this was meant to have happened in international waters, but in 1992, it was established that it was in Iranian waters.

At 10.15 a.m., Iran Air Flight 655 took off from nearby Bandar Abbas International Airport. The commercial flight was on an Airbus 300, and had 290 people on board. It was headed for Dubai. But at 10.47 a.m., the USS Vincennes' radar picked up the flight.

In the 1970s, the US had supplied Iran with 80 F-14 fighter jets. This could explain why when personnel on the USS Vincennes saw the Airbus 300 on its radar they thought it was a fighter jet. It's also worth noting that the airport was used by Iran's military along with civilian flights.

At 10.49 a.m., the USS Vincennes sent distress signals asking Iran Air 655 to identify itself, but it didn't. According to the Navy, the plane began to descend. This was later proven to be untrue. At 10.51 a.m., it was warned again. In total, the Navy said it warned the plane seven times — three by a civilian channel, and four by a military channel.

Alongside the grief, Iran was outraged. Many in Iran's government didn't believe the attack was an accident at all, but a message sent by the US. In response to the attack, Iran's government said it would "avenge the blood of our martyrs."

President Ronald Reagan and Admiral William Crowe defended the US Navy's actions. They both said Roger's first responsibility had been the safety of his ship and crew. Crowe told media he had "sufficient latitude" to defend his crew. "They do not have to be shot at before responding," he said.
