The Marine Corps on Monday identified the three Marines killed on Sunday when their Osprey aircraft crashed during a training exercise off the northern coast of Australia.
The MV-22B Osprey was carrying 23 service members when it went down at about 9:30 a.m. near the Tiwi Islands, in the Northern Territory of Australia, Marine officials said.
The three Marines killed were identified as:
"We are deeply saddened by the loss of three respected and beloved members of the MRF-D family. Our thoughts and prayers remain with the families and with all involved," said Col Brendan Sullivan, commanding officer of Marine Rotational Force-Darwin.
Three others Marines remain hospitalized, one in critical condition, according to a Marine press release.
The Osprey had been transporting troops as part of a "routine training exercise" in support of Exercise Predators Run, a joint military exercise, officials said.
