condition to prevent a major German air attack, with only 16 Hurricanes and a couple of Gladiator aircraft serviceable. On 11 January 1941, 10 more Ju 87s were sent to sink Illustrious. They chanced upon the light cruisers and . Hits were scored on both; Southampton was so badly damaged her navy escorts scuttled her. Over the next 12 days, the workers at the shipyard in the Grand Harbour repaired the carrier under determined air attack so that she might make Alexandria. On 13 January, the Ju 87s, now equipped with SC 1000 bombs failed to achieve a hit. On 14 January, 44 Ju 87s scored a hit on the ill-fated after lift. On 18 January, the Germans switched to attacking the airfields at Hal Far and Luqa in an attempt to win air superiority before returning to Illustrious. On 20 January, two near misses breached the hull below the water line and hurled her hull against the wharf. Nevertheless, the engineers won the battle. On 23 January, she slipped out of Grand Harbour, and arrived in Alexandria two days later. The carrier later sailed to America where she was kept out of action for a year. The Luftwaffe had failed to sink the carrier. However, their losses were few—three aircraft on 10 January and four Ju 87s over several weeks—and the Germans had impressed the British with the effectiveness of land-based air power. They withdrew their fleet's heavy units from the central Mediterranean and risked no more than trying to send cruisers through the Sicilian Narrows. Both the British and Italian navies digested their experiences over Taranto and Malta. German and Italian air superiority The appearance in February of Messerschmitt Bf 109 E-7 fighters of 7. Staffel (squadron) Jagdgeschwader 26 (26th Fighter Wing or JG 26), led by Oberleutnant Joachim Müncheberg, quickly led to a rise in RAF losses; the German fighter pilots were experienced, confident, tactically astute, better-equipped and well-trained. The Allied pilots on Malta had little combat experience and their Hawker Hurricanes were worn-out and for four months, JG 26 had few losses. The Luftwaffe claimed 42 air victories, 20 of them (including one over Yugoslavia) credited to Müncheberg. The RAF Hurricanes were kept operational by being patched up and cannibalised and their performance, already inferior to the Bf 109E-7, deteriorated. Five Hurricanes arrived at Malta in early March, another six on 18 March. but five Hurricanes
