The Allied Air Forces had used 233,847 rounds of ammunition, and dropped two-hundred and sixty-one 500-pound and two-hundred and fifty-three 1,000-pound bombs. They claimed 19 hits and 42 near misses with the former and 59 hits and 39 near misses from the latter. Of the 137 bombs dropped in low level attacks, 48 (35 percent) were claimed to have hit but only 29 (7.5 percent) of the 387 bombs dropped from medium altitude. This compared favourably with efforts in August and September 1942 when only 3 percent of bombs dropped were claimed to have scored hits. It was noted that the high and medium altitude attacks scored few hits but dispersed the convoy, while the strafing runs from the Beaufighters had knocked out many of the ships' anti-aircraft defences. Aircraft attacking from several directions at once had confused and overwhelmed the Japanese defences, resulting in lower casualties and more accurate bombing. The results therefore vindicated not just the tactics of mast height attack but of mounting coordinated attacks from several directions. The Japanese estimated that at least 29 bombs had hit a ship during the battle. This was a big improvement over the Battle of Wau back in January, when Allied aircraft attacked a Japanese convoy consisting of five destroyers and five troop transports travelling from Rabaul to Lae, but managed to sink just one transport and beach another.
