No. 428 Squadron RCAF
No. 428 Squadron RCAF was the ninth long-range heavy bomber Article XV squadron formed overseas during the Second World War at RAF Dalton in Yorkshire, England on November 7, 1942. The squadron was initially assigned to No. 4 Group RAF. With the creation of No. 6 Group RCAF, the squadron was reallocated on January 1, 1943 operating with it until April 25, 1945.
No. 464 Squadron RAAF
The squadron was officially formed on 1 September 1942 at RAF Feltwell, Norfolk in the United Kingdom, as an Article XV squadron under the Empire Air Training Scheme. Although technically a squadron of the RAAF, its personnel were drawn from many countries and upon formation only about 30 percent were Australian. This fluctuated and later in the war this grew to just over 50 percent. Upon formation, the squadron's first commanding officer was a South African, Wing Commander Ronald Young. No. 464 Squadron was initially equipped with Lockheed Ventura light bombers, and participated in its first operation on 6 December. Dubbed Operation Oyster, it was an attack on the Philips radio valve factory at Eindhoven, in the Netherlands. The squadron lost three aircraft to anti-aircraft fire during the attack, but inflicted significant damage on the target.
