A flotilla of military and support vessels Tuesday will conduct a joint security exercise off of the entrance to Pearl Harbor. Persons viewing this exercise from shore or from other vessels should not be alarmed - this is only an exercise. The U.S. Coast Guard Cutter Galveston Island along with small boats from Naval Station Pearl Harbor, Naval Submarine Support Command, and the Coast Guard Maritime Safety and Security Team Honolulu will exercise a variety of security scenarios. Additional support vessels include a Coast Guard Auxiliary vessel and several small boats and personal water craft from the Afloat Training Group Middle Pacific. These exercises will involve numerous high speed small boat maneuvers as well as flashing handheld lights and short blasts from air horns.
