The remaining offensive aircraft consisted of four RAF squadrons of Bristol Blenheim I and IV light bombers (27, 34, 60, 62 Squadrons), two RAAF squadrons (1 and 8) of Lockheed Hudsons, and two RAF squadrons of Vickers Vildebeest torpedo bombers (36 and 100). The Vildebeests were considered obsolete for the European theatre of operations. No 36 Squadron had some Fairey Albacore biplanes. There were also two PBY Catalina flying boats of No. 205 Squadron RAF and three Catalinas from the Royal Netherlands East Indies Army Air Force at Singapore.
