In the fall of 1944, Marine Air Group-45 set up shop at Ulithi Atoll and received the task of suppressing the bypassed Japanese bases in the Carolines. MAG-45’s biggest and most important target was Yap, which included a large airfield capable of handling twin-engine bombers. The air group’s Avenger squadron, initially VMTB-232 and later VMSB-245, also provided anti-submarine patrols around the fleet anchorage at Ulithi. In November, two Japanese submarines launched five midget subs which succeeded in sinking a U.S. Navy oiler. Marine Avengers sank two of the midget subs.
In the months that followed, the air group flew night intercept operations with VMF (N)-542’s F6F-5N Hellcats, carried out ceaseless attacks on Yap, Fais and Sorol Islands. Though they encountered only occasional Japanese aircraft, the flak over these targets was often intense and so dangerous the crews were told not to drop below six thousand feet during their attack runs.
MAG-45’s job was a thankless one, their efforts and missions lost to the American people as the tide of war advanced ever closer to the shores of the Japanese Homeland. Yet, it was in these grinding, attritional missions that the Marine aviators demonstrated a supreme level of dedication to their craft and cause. Day in and day out, the struck the same targets to ensure the strips at Yap could not be used to launch surprise raids against the U.S. warships at anchor in Ulithi, which had become a key forward replenishing base for the fast carrier task forces. There was little chance to participate in a major battle that could make headlines and history, and almost no opportunity for the fighter pilots to score aerial kills. Yet they were steadfast and carried out their missions with deadly effectiveness until the Japanese surrender in August 1945.
In honor of their all-but unknown efforts, here are some photographs from that backwater campaign.
