 Air attacks on Arawe dropped off after 1 January. As a result of the heavy losses they suffered during attacks on Arawe and Cape Gloucester, and the damage caused by Allied raids on Rabaul, Japanese air units conducted only small-scale raids at night after this date. The IJN fighter units based at Rabaul and nearby Kavieng were also kept busy throughout January and February 1944 defending their bases from continuous Allied air attacks. Few raids were made against the Arawe area after 90 mm anti-aircraft guns were established there on 1 February. These weak attacks did not disrupt the Allied convoys. In the three weeks after the landing, 6,287 short tons (5,703 t) of supplies as well as 541 artillery guns and vehicles were transported to Arawe. On 20 February, the Japanese air units at Rabaul and Kavieng were permanently withdrawn to Truk, ending any significant aerial threat to Allied forces in New Britain from the IJN.
