One person was rescued and five others missing after a U.S. Navy helicopter crashed into the Pacific Ocean on Tuesday afternoon.
The MH-60S helicopter crashed into the sea about 60 nautical miles off the coast of San Diego during a routine flight operation at 4:30 p.m., military officials said.
Several Coast Guard and Navy planes and ships were conducting the search and rescue operation, officials said.
At least one member of the service has been rescued and five others missing, military officials said.
According to the statement, it is unclear how many sailors were on board the plane, which was boarded on the USS Abraham Lincoln.
San Diego is home to the second largest naval base in the country.
The MH-60S is a versatile aircraft that typically carries a crew of four people and is used in missions such as combat support, humanitarian disaster relief and search and rescue.
