The 125 patrol cutter Tiger was designed for prohibition enforcement. Tiger and Pearl Harbor-based sister cutter Reliance were reconfigured for anti-submarine duties (Coast Guard Collection).
N THE BATTLE, Coast Guard units served
alongside of the Navy, firing anti-aircraft
barages against the Japanese attackers and performing harbor and anti-submarine patrols. The Coast Guard had supported the war effort even before Pearl Harbor.
The service had been transferred from the Department of the Treasury to the Navy in November 1941; however Coast Guard units in Hawaii had served alongside the Navy since the summer. By the time of the attack, these units had been integrated with their Navy counterparts.
Supporting U.S. Naval forces on December 7 were the Coast Guard cutters, patrol boats, bases, stations, lighthouses and personnel assigned to the 14th Naval District.
