The search for a Navy SEAL missing at sea since Tuesday extended farther northwest from Kaena Point today, the Coast Guard said.

A Coast Guard C-130 aircraft, a 45-foot response boat, the 110-foot cutter Kiska and the Navy tug Sea Commando are continuing the search for the 34-year-old SEAL, who became separated from other members of his command during ocean swim training near Kaena Point Tuesday afternoon.

The Navy said the missing man is a first class petty officer assigned to a Hawaii-based special-warfare unit. An official said 10 sailors were using two rigid-hull inflatable boats during the training.  

Navy officials would not name the SEAL or his unit. SEAL Delivery Vehicle Team 1 is the main unit for the commandos in Hawaii, with about 100 SEALs.

The Honolulu Fire Department set up an incident command post at Kaena Point, the Coast Guard said.
