US Central Command (CENTCOM) announced on Tuesday that US military personnel have rescued two crew members of an Apache helicopter that crashed into the water off the coast of Oman on Monday evening.

On June 8, at 19:33 Eastern Time, US forces rescued two crew members of a US Army AH-64 Apache helicopter when their helicopter crashed into the water off the coast of Oman while conducting a patrol in regional waters, according to a statement posted on social media by CENTCOM.

The servicemembers were successfully rescued within about two hours and are in stable condition.

The cause of the incident is under investigation.

The rescue operation was led by the US Naval Forces Central Command and the 82nd Airborne Division, with support from the US Air Force and Marine Corps units, including the US 5th Fleet's 59th Task Force

Speaking to reporters early Tuesday morning at John F. Kennedy International Airport in New York, US President Donald Trump specifically noted that everything was fine with the pilots.

Later on Tuesday, CENTCOM revealed an exclusive detail of the operation: the crew members were found and evacuated from the water using an unmanned surface vehicle (USV), a maritime drone.

This was the first time in the history of the US military that unmanned motor boats were used in combat operations to rescue people, the CENTCOM spokesperson, US Navy Captain Tim Hawkins, confirmed in a statement to Fox News.
