A comprehensive resource for safe and responsible laser use
A group of three U.S. ships — a destroyer, an amphibious assault ship, and a dry cargo ship — were transiting international waters in the Strait of Hormuz, according to a U.S. military statement. The Iranian naval vessel, said by one source to be a missile ship, came within 800 yards of the assault ship and scanned two of the U.S. ships with a spotlight.
The helicopter was flying alongside the deployment when the Iranian targeting laser was aimed at it, setting off the flares.
There was no report of injury to the helicopter pilots. A spokesperson for the U.S. Navy’s Fifth Fleet said “Illuminating helicopters with lasers at night is dangerous as it creates a navigational hazard that can impair vision and can be disorienting to pilots using night vision goggles.”

UPDATED JULY 16 2017 - Iran claimed it did not point a laser at the helicopter. The Tasnim News Agency said “A top commander of Iran’s Navy denied reports that the country’s naval forces had pointed a laser at an airborne US Marine Corps helicopter in the Strait of Hormuz back in June. Commander of Iran's First Naval Zone Admiral Hossein Azad categorically denied reports of such incident.”
The report had no additional details, such as what could have set off the helicopter’s flares as claimed by the initial U.S. report.
From the Tasnim News Agency and the Tehran Times
There were no reports of injuries or damage caused by the laser, so the Navy “believes it was not of industrial or military grade quality….” A Navy public affairs officer from the U.S. Naval Forces Central Command called the Iranian use of the laser as “unsafe” and “unprofessional.”

Note: The U.S. Navy in November 2014 deployed the first laser weapon sent into trials on an active duty warship, the USS Ponce. Six commercial welding lasers are merged into a single beam of 30 kilowatts, that can be used against targets including Iranian gunboats, according to SlashGear.
