Removed from the Navy List.

Authors' Notes:
[1] Dutch sources claim the aircraft and the squadrons involved in the strike were: No. 18 Dutch Squadron - 10 B-25s, No. 2 RAAF Squadron - 10 B-25, and No. 82 RAAF Wing - 9 B-24s. Two of the B-24s that attacked about 20 minutes later were shot down by Japanese Army fighters (probably Nakajima KI-43 "Oscars" and/or Nakajima KI-44 "Tojos").
