Sept. 1 (UPI) -- Five U.S. Navy service members are missing after a military helicopter crashed off the coast of San Diego, authorities said.

The Navy said the MH-60S chopper, operating off the USS Abraham Lincoln, went into the water on Tuesday afternoon about 60 nautical miles off shore.

The helicopter was carrying six people. One sailor was rescued.

"Search and rescue operations are ongoing with multiple Coast Guard and Navy air and surface assets," the Navy said in a statement.

Five sailors aboard the Abraham Lincoln were injured as a result of the crash. Three sustained minimal injuries and remained aboard the ship while two others were transported ashore for medical treatment.

The helicopter crew had been conducting routine flight operations, the Navy said.
