May, Wasp and Eagle delivered 64 more Spitfires (Operation Bowery). Malta now had five full Spitfire squadrons; No. 126, 185, 249, 601 and 603 Squadrons. The impact of the Spitfires was apparent. On 9 May, the Italians announced 37 Axis losses. On 10 May, the Axis lost 65 aircraft destroyed or damaged in large air battles over the island. The Hurricanes were able to focus on the Axis bombers and dive-bombers at lower heights, while the Spitfires, with their superior rate of climb, engaged enemy aircraft at higher levels. From 18 May – 9 June, Eagle made three runs carrying another 76 Spitfires to Malta. With such a force established, the RAF had the firepower to deal with any Axis attacks. By the spring of 1942, the Axis air forces ranged against the island were at their maximum strength. The main adversaries for the defenders were the 137 Bf 109Fs of JG 53 and II./JG 3 'Udet' and the 80 Macchi C.202s of the 4th and 51st Stormo. Bomber units included 199 Junkers Ju 88s of II./Lehrgeschwader 1, II and III./Kampfgeschwader 77, I./Kampfgeschwader 54, and 32–40 Ju 87s. However, in May the numerical and technical improvements in the RAF defences wrested air superiority from the Luftwaffe. By the end of May 1942, Kesselring's forces had been reduced to just 13 serviceable reconnaissance aircraft, six Bf 110s, 30 Bf 109s and 34 bombers (mostly Ju 88s): a total of 83 compared with several hundred aircraft two months earlier. Axis target convoys After the battles of May and June, the air attacks were much reduced in August and September. While air superiority had been won back by the RAF, German pressure had allowed Axis convoys to re-supply the Panzer Army Africa. The island appeared to the Axis forces to be neutralised as a threat to their convoys. Rommel could now look forward to offensive operations with the support of the Luftwaffe in North Africa. At the Battle of Gazala he won a major victory, while the Battle of Bir Hakeim was less successful. Even so, he was soon back in Egypt fighting at El Alamein. Despite the reduction in direct air pressure over Malta itself, the situation on the island was serious. It was running out of all essential commodities, particularly food and water, as the bombing had crippled pumps and distribution pipes. Clothing was also hard to come by. All livestock
