the assembly line in chaos, and the employees not doing their work: Beaverbrook, who had disturbed the Air Ministry by agreeing with the vision of Air Vice Marshal Hugh Dowding that Britain at that time needed defensive fighters over attacking bombers, immediately cancelled all Castle Bromwich contracted bombers, which at that point included the Handley-Page Halifax and the Vickers Wellington. He then sent in experienced management staff and workers from Supermarine, and gave over control of the factory to Vickers-Armstrong (Supermarine's parent company). Although it would take some time to resolve the problems, CBAF achieved full production in June 1940, when 10 Spitfire Mk IIs were built; 23 in July; 37 in August; and 56 in September. No. 611 Squadron at RAF Digby the first squadron to receive the Mk II in August 1940, notably late in the Battle of Britain. The wisdom of the shadow factory scheme was demonstrated in September 1940, when the Supermarine factory in Southampton was bombed, and production there temporarily stopped. CBAF went on to become the largest and most successful plant of its type during the 1939–45 conflict. As the largest Spitfire factory in the UK, by producing a maximum of 320 aircraft per month, it built over half of the approximately 20,000 aircraft of this type. By the time production ended at Castle Bromwich in June 1945, a total of 12,129 Spitfires (921 Mk IIs, 4,489 Mk Vs, 5,665 Mk IXs, and 1,054 Mk XVIs) had been built. Subsequently receiving an order for 200 production aircraft, the first CBAF Lancaster was flown on 22 October 1943 by Alex Henshaw. Given the airframe number HK535 and fitted with Merlin 22 engines, it was issued to No. 463 Squadron Royal Australian Air Force. It was lost on a raid over Lille, France, during the night of 10/11 May 1944. Production of Lancasters reached a peak of 25 in December 1944, a record for the quantity produced anywhere. Some original war time features can still be seen such today, such as the faded remains of green camouflage paint. This can still be seen on the top of some older production buildings such as F Block that is now used as trim and final assembly for the Jaguar XJ. Close inspection will also reveal that all the cast-iron hoppers of the factory's rainware have a winged-roundel motif cast into them. At the Jubilee celebrations in 1997, a
