A day after the crash of a U.S. Navy helicopter that had been aboard the USS Abraham Lincoln off the coast of San Diego, five sailors remain missing.

In an update Wednesday on continuing search and rescue operations, officials disclosed that five sailors aboard the Abraham Lincoln at the time were also injured in the incident. 

The MH-60S helicopter crashed around 4:30 p.m. Tuesday about 60 nautical miles off San Diego. One of the six sailors who were on the helicopter at the time of the crash was rescued later Tuesday. 

A U.S. Coast Guard official told Fox News on Wednesday afternoon that debris from the helicopter has been located in the ocean, but five crew members are still missing. Navy and Coast Guard teams have searched 600 square miles so far.

"Two of the five Abraham Lincoln Sailors were transported ashore for treatment, while three of the five Abraham Lincoln Sailors had minimal injuries and remain aboard the ship," the update said.  "An investigation into the cause of the incident is underway." 

The MH-60S is a versatile aircraft that typically carries a crew of about four and is used in missions including combat support, humanitarian disaster relief and search and rescue. USS Abraham Lincoln (CVN 72) on Tuesday also initially announced the search and rescue operations.
